You are developing code for a class named Account. The Account class includes the
following method:
You need to ensure that overflow exceptions are thrown when there is an error.
Which type of block should you use?
A. checked B. try C. using D. unchecked

Can I really put some comments here? Nov 14, 2017
Here is the answer for this question: https://msdn.microsoft.com/en-us/library/khy08726(v=vs.110).aspx Oct 18, 2017
Is the extraCents variable a member of the class?
I thought it would be prefixed with this. (I know it is not the aim of the question :) ) Oct 12, 2017
A Sep 12, 2017
You're correct. It would be *caught* by a try-catch block when thrown, but without the "checked" keyword it wouldn't be thrown in the first place. Aug 20, 2017
"For the arithmetic, casting, or conversion operation to throw an OverflowException, the operation must occur in a checked context. By default, arithmetic operations and overflows in Visual Basic are checked; in C#, they are not. If the operation occurs in an unchecked context, the result is truncated by discarding any high-order bits that do not fit into the destination type. "

I thought an overflow exception would be caught using a "try catch" block. I was wrong. May 28, 2017
Question No : 2 - Topic 1
You are developing an application in C#.
The application will display the temperature and the time at which the temperature was
recorded. You have the following method (line numbers are included for reference only):
You need to ensure that the message displayed in the lblMessage object shows the time
formatted according to the following requirements:
? The time must be formatted as hour:minute AM/PM, for example 2:00 PM.
? The date must be formatted as month/day/year, for example 04/21/2013.
? The temperature must be formatted to have two decimal places, for example 23-
45.
Which code should you insert at line 04? (To answer, select the appropriate options in the
answer area.)
Answer:
The answer is for ENGLISH environment. If my OS is Chinese, the answer is wrong. Mar 21, 2018
Can anyone explain about About temperature: {1:N2} ?? Mar 11, 2018
when I tested only "{0:t} {0:d} {1:N2}" gives the answer matches with the requirement. Nov 28, 2017
i am confused with this one Nov 21, 2017
About temperature: {1:N2} produce 23.45 not 23-45 Nov 17, 2017
string.Format("Temprature at {0:t} on {0:MM/dd/yyyy} is {1:N2}", DateTime.Now, 45.98555)
for the time format {0:t} will also do. Nov 15, 2017
The answer to this question is wrong. The correct format is {0:MM/dd/yyyy} Nov 14, 2017
Like many comments below addressed the answer should be {0:t}, {0:mm/dd/yy} and {1:N2} but there is no choice like that. Nov 8, 2017
string.Format("Temperature at {0:hh:mm tt} {0:MM/dd/yyyy} on {1:N2}", date, temp); Oct 26, 2017
output = string.Format("Temperature at {0:hh:mm tt} {0:MM/dd/yyyy} on {1:N2}", date, temp);
Oct 26, 2017
That would try to format temp as a date. The second part should be {0:mm/dd/yy}, but there is no such choice. Oct 20, 2017
no. the second dropdown still consumes the date variable so its still 0. Oct 14, 2017
And what about the {1:N2} outside of the brackets? Oct 13, 2017
I think if you chose {0:dd/mm/yy}, you will have the "minute" part of the DateTime(to have the "month" part, you need to put "MM"), and the year will be displayed on 2 digits, not on 4, as required in your example. Oct 12, 2017
should the second part be {1:mm/dd/yy} ?? Sep 16, 2017
The best answer according to the choices is "{0:t}", "{0:d}" and "{1:N2}". Sep 14, 2017
If it is month/day/year, how is that the format in the answer puts the day first? Sep 13, 2017

You are developing an application that will process orders. The debug and release versions
of the application will display different logo images.
You need to ensure that the correct image path is set based on the build configuration.
Which code segment should you use?
A. Option A B. Option B C. Option C D. Option D
Answer: C Explanation:
There is no such constraint (unless you define one explicitly) RELEASE.
http://stackoverflow.com/questions/507704/will-if-release-work-like-if-debug-does-in-c
I don't use any of the listed options because if your solution is in debug mode then anything in the #else isn't evaluated by the IDE for syntax errors. So if the name "imgPath" ever changes and you are in debug mode then you will get a syntax error in the #if block but not the #else block. Better use case is to set a local debug boolean in the #if structure and use that to dictate what to do instead so that the relevant code is always being scanned for syntax errors. Nov 20, 2017

You are creating an application that manages information about zoo animals. The
application includes a class named Animal and a method named Save.
The Save() method must be strongly typed. It must allow only types inherited from the
Animal class that uses a constructor that accepts no parameters.
You need to implement the Save() method.
Which code segment should you use?
A. Option A B. Option B C. Option C D. Option D
Answer: C Explanation:
When you define a generic class, you can apply restrictions to the kinds of types that client
code can use for type arguments when it instantiates your class. If client code tries to
instantiate your class by using a type that is not allowed by a constraint, the result is a
compile-time error. These restrictions are called constraints. Constraints are specified by
using the where contextual keyword.
http://msdn.microsoft.com/en-us/library/d5x73970.aspx
When used together with other constraints, the new() constraint must be specified last.

You are debugging an application that calculates loan interest. The application includes the
following code. (Line numbers are included for reference only.)
You have the following requirements:
? The debugger must break execution within the Calculatelnterest() method when
the loanAmount variable is less than or equal to zero.
? The release version of the code must not be impacted by any changes.
You need to meet the requirements.
What should you do?
A. Insert the following code segment at tine 05: Debug.Write(loanAmount > 0); B. Insert the following code segment at line 05: Trace.Write(loanAmount > 0); C. Insert the following code segment at line 03: Debug.Assert(loanAmount > 0); D. Insert the following code segment at line 03: Trace.Assert(loanAmount > 0);
Answer: C Explanation:
By default, the Debug.Assert method works only in debug builds. Use the Trace.Assert
method if you want to do assertions in release builds. For more information, see Assertions

You are developing an application that includes a class named Order. The application will
store a collection of Order objects.
The collection must meet the following requirements:
? Internally store a key and a value for each collection item.
? Provide objects to iterators in ascending order based on the key.
? Ensure that item are accessible by zero-based index or by key.
You need to use a collection type that meets the requirements.
Which collection type should you use?

You are developing an application that uses structured exception handling. The application
includes a class named ExceptionLogger.
The ExceptionLogger class implements a method named LogException by using the
following code segment:
public static void LogException(Exception ex)
You have the following requirements:
? Log all exceptions by using the LogException() method of the ExceptionLogger
class.
? Rethrow the original exception, including the entire exception stack.
You need to meet the requirements.
Which code segment should you use?
A. Option A B. Option B C. Option C D. Option D
Answer: A Explanation:
Once an exception is thrown, part of the information it carries is the stack trace. The stack
trace is a list of the method call hierarchy that starts with the method that throws the
exception and ends with the method that catches the exception. If an exception is re-
thrown by specifying the exception in the throw statement, the stack trace is restarted at
the current method and the list of method calls between the original method that threw the
exception and the current method is lost. To keep the original stack trace information with
the exception, use the throw statement without specifying the exception.

You are developing an application that accepts the input of dates from the user.
Users enter the date in their local format. The date entered by the user is stored in a string
variable named inputDate. The valid date value must be placed in a DateTime variable
named validatedDate.
You need to validate the entered date and convert it to Coordinated Universal Time (UTC).
The code must not cause an exception to be thrown.
Which code segment should you use?
A. Option A B. Option B C. Option C D. Option D
Answer: A Explanation:
AdjustToUniversal parses s and, if necessary, converts it to UTC.
Note: The DateTime.TryParse method converts the specified string representation of a
date and time to its DateTime equivalent using the specified culture-specific format
information and formatting style, and returns a value that indicates whether the conversion
succeeded.

An application includes a class named Person. The Person class includes a method named
GetData.
You need to ensure that the GetData() from the Person class.
Which access modifier should you use for the GetData() method?
A. Internal B. Protected C. Private D. Protected internal E. Public
Answer: B Explanation:
Protected - The type or member can be accessed only by code in the same class or
structure, or in a class that is derived from that class.
http://msdn.microsoft.com/en-us/library/ms173121.aspx
The protected keyword is a member access modifier. A protected member is accessible
within its class and by derived class instances.
"You need to ensure that the GetData() from the Person class." => That's an incomplete sentence Aug 16, 2017
Question asks: "You need to ensure that the GetData() from the Person class." ??? Something is missing! From the answer I suppose it should be "You need to ensure that the GetData() can only be called from the Person class itself or classes derived from the Person class." Aug 8, 2017
Jun 26, 2017
correct
because if you have a class as Employee derived from Person, you will still able to GetData() because Employee is Person Jun 23, 2017
the correct answer to this question is C, private Jun 5, 2017
And even with this wording, the "correct" answer would still be wrong. Question should ask for "access from the class itself and derived classes". May 11, 2017
"You need to ensure that the GetData() from the Person class." misses some information like "You need to ensure that the GetData() can only be called from the Person class.". May 3, 2017
Question No : 15 - Topic 1
You are developing an application that will include a method named GetData. The
GetData() method will retrieve several lines of data from a web service by using a
System.IO.StreamReader object.
You have the following requirements:
? The GetData() method must return a string value that contains the entire response
from the web service.
? The application must remain responsive while the GetData() method runs.
You need to implement the GetData() method.
How should you complete the relevant code? (To answer, drag the appropriate objects to
the correct locations in the answer area. Each object may be used once, more than once,
or not at all. You may need to drag the split bar between panes or scroll to view content.)
Answer:
public async void GetData(WebResponse response) Mar 28, 2018
it is wrong can't have 2 awaits, the code is suppose to be like this
public async void GetData(WebResponse response)
{
string urltext;
var sr = new StreamReader(response.GetResponseStream());
urltext = await sr.ReadToEndAsync();
} Mar 28, 2018
Yeah. Its typos Mar 7, 2018
Looks like that syntax could potentially work in another scenario but with "sr.ReadToEndAsync()" it will cause a syntax error because the first await is expecting its argument to produce a task(of T) but it doesn't. I was able to get code with a double await in it to compile with a function whose signature looked like: "System.Threading.Tasks.Task(of System.Threading.Tasks.Task(of T)) SomeFunc()". Nov 20, 2017
async
await
ReadToEndAsync(); Nov 11, 2017
async
await
ReadToEndAsync(); Nov 11, 2017
Actually, I believe it's intentional. If I'm not mistaken, the second await is used to retrieve the value of the asynchronous read method. The first await is then used for the GetData method. Nov 2, 2017
it will be urlText= await await sr.ReadToEndAsync(); then???
there will be 2 await on the same method call, right? Nov 2, 2017
I would have returned a Task object, not void (I mean public async Task...) Oct 12, 2017
I think that's wrong Oct 10, 2017
It's wrong. Oct 9, 2017
the double "await" operator is intentionally or its an wrong? Sep 24, 2017
It says in the question: "The GetData() method will retrieve several lines of data from a web service" Sep 19, 2017
The answer is right, check out the statement : "The GetData() must return a string value that contains the ENTIRE response from the web service." Sep 19, 2017
I believe ReadLineAsync() should be there at ReadToEndAsync() Sep 13, 2017

You are developing an application by using C#.
The application includes an object that performs a long running process.
You need to ensure that the garbage collector does not release the object's resources until
the process completes.
Which garbage collector method should you use?
A. ReRegisterForFinalize() B. SuppressFinalize() C. Collect() D. WaitForFullGCApproach()
Answer: B
Collect() this is correct according to an exam 70-483 Mar 12, 2018
The correct answer is C = Collect() According to the 70-483 book Page 176 - "Collect will execute a garbage collection, freeing as much memory as possible at that time, which can be a very expensive process. This won't prevent the garbage collector from executing during your time-sensitive code, but it will make it less likely to happen." Nov 2, 2017
c Oct 30, 2017
SuppressFinalize()
Sep 13, 2017
correct answer will be C.. Aug 3, 2017
I'm pretty sure the answer is C. SuppressFinalize() doesn't actually prevent garbage collection, it only prevents Finalize from being called (usually used to close resources) before garbage collection. I don't think there is a way to tell the GC to stop, but Collect() will reduce the chances and maximize available resources before the task starts. Jul 28, 2017
KeepAlive() is according to an exam 70-483 trainee book the correct answer for this issue. Jul 26, 2017
KeepAlive() seems to be correct. The SuppressFinalize() method seems to be used for completely different scenarios (Dispose design pattern). Additionally the documentation on the KeepAlive() method seems to be used for these scenarios. See https://msdn.microsoft.com/en-us/library/system.gc.keepalive(v=vs.110).aspx Jul 3, 2017
SuppressFinalize() Jul 2, 2017
Jun 30, 2017
Jun 23, 2017
I think that the answer is correct : https://msdn.microsoft.com/en-us/library/system.gc.suppressfinalize(v=vs.110).aspx Jun 5, 2017
KeepAlive() is the correct answer. Jun 5, 2017
Which is the correct answer please? May 26, 2017
But then which is the correct answer...? May 16, 2017
Completely wrong. SupressFinalize() is called from Dispose to prevent the call of the Finalizer on an object of a class which has on declared. It will not prevent garbage collection on the object. May 14, 2017
Question No : 18 - Topic 1
You are developing an application that includes the following code segment. (Line numbers
are included for reference only.)
You need to ensure that the application accepts only integer input and prompts the user
each time non-integer input is entered.
Which code segment should you add at line 19?
A. If (!int.TryParse(sLine, out number)) B. If ((number = Int32.Parse(sLine)) == Single.NaN) C. If ((number = int.Parse(sLine)) > Int32.MaxValue) D. If (Int32.TryParse(sLine, out number))
Answer: A Explanation:
B and C will throw exception when user enters non-integer value. D is exactly the opposite
what we want to achieve.
Int32.TryParse - Converts the string representation of a number to its 32-bit signed integer
equivalent. A return value indicates whether the conversion succeeded.
http://msdn.microsoft.com/en-us/library/f02979c7.aspx
This doesn't give an explanation for why D is not the correct answer. The reason why it's wrong is because of the resulting flow options after we check the result of the TryParse operation. TryParse returns 1 if the operation succeeds, 0 if it fails. If the operation succeeds we don't want to return false from the function, we want to assign the value of "val" and return true. Hence the correct answer is A. Oct 19, 2017
No it is not. It is true that 0/false is returned inf the conversion fails but if you insert the code from D you would have:
If (Int32.TryParse(sLine, out number))
{
return false;
} else {... return true; }
the method would return false if the integer could be parsed, and true if the conversion fails.
That is definitely not what we want here. Aug 10, 2017
If the conversion fails, you will not enter the return false-state. Answer A is correct. D is the same as
if(Int32.TryParse(sLine, out number) == true) which is not true in this case. Zero evaluates to false Aug 10, 2017
Executed the code in visual studio and found the correct answer as 'D' because TryParse() returns 0 if conversion failed.In this code we should return false if conversion failed hence correct answer is D. Aug 8, 2017
If(!Int.TryParse(sLine, out number)) Jul 2, 2017

actions from the list of actions to the answer area and arrange them in the correct order.)
Answer:
Question No : 20 - Topic 1
You are reviewing the following code:
For each of the following statements, select Yes if the statement is true. Otherwise, select
No.
Answer:
All is Yes , for third yes as it treated as int values , for first try below :
var user = new User();
user.groub= Group.Users | Group.Supervisors;
Console.WriteLine(user.groub);
if ((user.groub & Group.Supervisors) ==Group.Supervisors)
Console.WriteLine("true"); Mar 23, 2018
On Object Creation,
user.UserGroup = 0
Group.Administrator = 8
So, the answer will be
1. NO
2. NO
3. YES Mar 7, 2018
Yes, Yes, Yes. Explanation: (1) A user can be member of more than one group by setting e.g. user.UserGroup = Group.Users | Group.Supervisors; In this case the user is considered member of Users and Supervisors. (2) If you did the following user.UserGroup = Group.Administrators then user.UserGroup == Group.Administrators is true, because 8 == 8 is true (3) If you did the following user.UserGroup = Group.Supervisors then user.UserGroup < Group.Administrators is true, because 2 < 8 is true. All tested in VS. Mar 5, 2018
Dsmolevski it is a flag thus you can use the bitwise OR "|" to combine values Nov 2, 2017
It's Yes, Yes, Yes.
The third one is user.UserGroup <= Group.Administrators Nov 2, 2017
No, Yes, Yes .. tested and verified. Nov 2, 2017
yes Oct 24, 2017
No, Yes, Yes...100% tested in LINQPAD Oct 23, 2017
I was confused by the lt; on the last statement. So likeMgkoch I did a little script to test the values. If user.UserGroup = Group.Supervisors | Group.Admins the user.UserGroup becomes 10. So it took more than one user group on. Yes for the first. Yes for the second if the user is only an Admin. Yes for the third since supervisor(2) < admin(8). Oct 12, 2017
Answer : YES,YES,YES
Explanation :
1. User Can belong to More than Group. -TRUE
2. If User belongs to administrator then comparing against the administrator will result to True.
3. If user belongs to only supervisor group and checking if supervisor < administrator will result to True Sep 19, 2017
In my opinion.... No, Yes, Yes Aug 30, 2017
Correct Answer: Yes, Yes, Yes
lt; = less than Aug 29, 2017
When you add the FlagsAttribute to an enum you should think of it like a bit operator. This question is confusing because it normally would be 0, 1, 2, 4 as that is how a byte works, although I do not think it really matters...at any rate in regards to the question a value of 3 then would mean you belong to the Users (1) and the Supervisors (2) group. A value of 17 would mean you belong to all of the groups (8 + 4 + 2 + 1). The first part would be yes, the second part would be yes (2 == 2), the third part (assuming no syntax error) would also be true as 2 is less than 8 Jul 28, 2017
why not yes, yes, yes. Please explain why the final expression isn't evaluated as 2 < 8 Jul 25, 2017
It should be YES, YES NO Jul 11, 2017
Yes, Yes, Yes. If user only has supervisors group, user.UserGroup IS less than Group.Administrators. Try it in VS first and verify... [Flags()]
public enum Group
{
Users = 1,
Supervisors = 2,
Managers = 4,
Administrators = 8
}
public class User
{
public Group UserGroup { get; set; }
}
static void Main(string[] args)
{
User user1 = new User();
Console.WriteLine("Setting User to Users and Supervisors");
user1.UserGroup = Group.Users | Group.Supervisors;
if ((user1.UserGroup & Group.Users) == Group.Users) Console.WriteLine("User is Users");
if ((user1.UserGroup & Group.Supervisors) == Group.Supervisors) Console.WriteLine("User is Supervisors");
Console.WriteLine("Setting User to Administrators");
user1.UserGroup = Group.Administrators;
if (user1.UserGroup == Group.Administrators) Console.WriteLine("User is Administrators");
Console.WriteLine("Setting User to Supervisors");
user1.UserGroup = Group.Supervisors;
if (user1.UserGroup < Group.Administrators) Console.WriteLine("User is less than Administrators");
Console.ReadLine();
} Jul 2, 2017
True, True, True (Tested in VS). 1) can have more groups (its how flags works) 2) yes 3) correct question is: "user.UserGroup < Group.Administrators". And it returns true because Supervisors is less than Administrator (look at values of flags). Jun 30, 2017
Bdosbdos, what about user.UserGroup = Group.Manager | Administrators? Corect is Yes, Yes, No Jun 28, 2017
Note : user.UserGroup == 2 when user.UserGroup == Group.Supervisors. Last has to be Yes.
A user might be part of more than one group in this particuliar situation, but that's only because of the misleading flags of the enum... Nothing infers against new groups set to
[System.FlagsAttribute()]
public enum Group
{
Users = 1,
Supervisors = 2,
Devs = 3, //New one
Managers = 4,
Retailers = 5, //Another new one
Administrators = 8
}
But yes, AS STATED IN THE QUESTION and said in Visionapp.Development, a user CAN be part of more than one group, when the flags are bit-compatibles.
-> (with the "in-the-question" enum)
user.UserGroup = Group.Users | Group.Managers; //user.UserGroup = 5
if ((user.UserGroup & Group.Users) == Group.Users) { Console.WriteLine("UserGroup is part of Users"); } // "5 & 1" returns 1 (bitwise conversion)
if ((user.UserGroup & Group.Managers) == Group.Managers) { Console.WriteLine("UserGroup is part of Managers"); } // "5 & 4" returns 4 (bitwise conversion)
-> (with the "+Devs-and-Retailers" enum)
user.UserGroup = Group.Retailers; //user.UserGroup = 5 (== same as above [!! Woups !!])
if ((user.UserGroup & Group.Users) == Group.Users) { Console.WriteLine("UserGroup is part of Users"); } // "5 & 1" returns 1 [!! Woups !!]
if ((user.UserGroup & Group.Managers) == Group.Managers) { Console.WriteLine("UserGroup is part of Managers"); } // "5 & 4" returns 4 [!! Woups !!] Jun 20, 2017
"user.UserGroup < Group.Administrators" for the last part of the question. Jun 20, 2017
Bdos is wrong.. Jun 18, 2017
the User can't be a member more than one group because of that the property is not a collection of group. Ienumebrable<group> != group, [no, yes, no] Jun 10, 2017
Correct answer should be: Yes,Yes, No. Look on last: "If user belongs to only the Supervisors group". May 29, 2017
This is confused by the comments below..please make it clear May 11, 2017
A user can be member of more than one of groups should be true as enum has flags attribute set. May 3, 2017
