1. Exam Question Preparation and Review
Hello, folks, and welcome back. So I went ahead and updated the case study questions. I wanted to make sure that they were as realistic as possible. And so what you’re going to have to do is They’re going to give you a case study question, and they’ll have the question in there, but actually they’re going to give you a good number of case study questions. I got around; I believe the exam included at least eight or nine case study questions. Now there are four case study questions, but on the fully released version of the test, only two out of the four case studies were actually tested, at least in the pool that I had. So just so you know how they’re going to test you, and I’m going through two examples with you here just to make sure you get it because I found it actually very confusing because, again, Google doesn’t do a particularly good job at explaining things to the average Joe. So if you’re not a developer, you really don’t know what they’re talking about half the time.
And even though I do have a developer background, I still had to look at it a few times to really understand what they’re asking. So I want to make sure we get this. I want you to be as successful as possible. Okay? So let’s do this. So the first thing I’d like you to do is go to, and the link will also be provided here. Also in the case study section that you just finished. So go over to the case study, and let’s go over to the case study that we are looking at right now, which is going to be Mount Kirk. So how have you said that? So we go over to Mount Kirk’s, and I think I spelled that wrong. My bad. Now if you go over there and read the case study again, I’m not going to read it all to you; just a few things on the exam will make you want to read the case study in full, but you’ll want to go back and reread exactly what they’re talking about. So again, try to discern whether it’s a technical requirement that they’re looking at or whether they’re asking you about a business requirement. Some case studies have both technical and business requirements in it. This one is just technical.
Now Mont Kirk Games is building a new game, and they’re essentially using no SQL databases. They’re also using Linux, so they’re building games, and essentially, this is going to use a lot of disparate data. They’re likely going to have a lot of mobility involved, as they say. Again, if you go up here, they also had issues with scaling, which is not a surprise; they use ETL. So again, we get that. So let’s go to the question that should give you an idea of what you can expect.
Okay? So they’re going to ask you to read the case study. So basically, you read the case study, then you go down to what they’re asking customers, requesting that we look at the MySQL database and migrate it to a GCP managed service. Okay? So we know right now that the customer wants a managed service. Now, I’ll be honest: most of Google’s databases as well as its big data service are managed. So that doesn’t help much, but it does help to some extent. And then we do know it’s MySQL. So again, this is the kicker. What you have to do is match MySQL to the Google Cloud service.
So let’s go. And again, I recommend you do this before you take this test. This is what killed me on the beta exam when I first took it because, again, there were 100 questions and it was a lot longer. And, to be honest, I’m not very good at remembering administrator, but you need to know the different services with Google rather than simply going to a webpage to validate your memory is correct. So again, this is what you want to do. Go over to the Google Cloud Platform and go to Products and Services here, right? And just again, before you take the test, go over and match up. So again, Mount Cook cooks. They’re using Linux. Okay, we knew there would be no sequel, as there would be no SQL database service. So again, we go back here and we go over to databases, right? And we want a managed NoSQL database.
What do we have here? We obtained cloud data storage. So again, we click on “cloud data store.” We know that it’s a highly scalable new SQL database. Again, it handles everything you need; it’s simple, integrated, and ETCA. Again, this is an option. Now, how is this managed? So again, it doesn’t say it’s managed. So again, you have to double check, and usually they advertise it, but it is actually a managed service. And I’m trying to understand why they don’t; I don’t know why they usually just sort of stick in your face. Where is it? Here it is. Yeah, again, it’s fully managed. So again, we go back to the case study, right? And we see that it is MySQL, right? But we looked at “no SQL,” right? just double checking, right? So just seeing it again, you can see that it’s very easy to confuse SQL and MySQL, no sequel.
Then you go back here, right? And guess what? You have MySQL here, fully manage MySQL.So we return; let’s just double-check that PostgreSQL and MySQL are fully managed. Okay? So again, we go back to the question. We know that this should work, right? Because again, just based on what is there, we know that again, you can use databases and analytic tools; this will all work. So that’s not an issue. So what we want to do now is just validate. Hey, is this actually a MySQL managed service? Right. Okay. So, cloud SQL, right? MySQL just wants to double check; you can see the little pop-up there. Again, it might be just at the top of the screen again. So we know that that’s a good start.
So we know that it’ll be a cloud SQL answer. So now what we want to do is try to understand, well, which one do we want to use for virtual machines? Basically, the customer is asking that we provide custom Linux images for their distro and persistent disks.
Okay? So we go back over here to Services, and now what we want to do is go over to Compute here and take a look at Compute Engine. And just to speed things up, we know that Compute Engine is actually what we want to use because, again, they’re running Linux. They support Linux over here, right? We know they will support Linux, custom machine types, and persistent disks. So again, these are the features. So a lot of the tests are, like I said, just matching the name to the feature.
But like I said, for me personally, the hard part is not just memorising the very similar names of the cloud services but also the very similar names of the databases and the services as well. Again, this is an exercise that you have to go through because you could easily fail this exam if you don’t know the difference or the correct name. Actually. Do you go with Cloud SQL or Cloud Data Flow or Dataproc?
Again, this is what I’m spending time on because this is where you’re going to get slammed if you don’t get it. So go over to App Engine. Now again, this is a managed platform. Now, they didn’t say they need a managed platform for servers, but that’s okay. But again, this isn’t really meant for hosting Linux machines; it’s meant for developing on. This is a platform as a service. And again, you’re not going to typically use this for servers; you’re going to use this more for applications. So that was sort of the kicker here. So we go back, and again, man, this thing just doesn’t want to let me go. We also choose the Cloud SQL compute engine. So again, that would be the right answer. So I just want to make sure you get the case study. I’ll take one more question, and I’m going to walk you through this. So now this is another service question, but it’s not a case study, so this is a good one to go through.
So what service would you specify for a customer that needs a direct physical connection between OnPrem and the Cloud Virtual Network Edge? Don’t be confused, because what’s going to happen is, and I’ll be honest, this is not best practice. But you’ll likely see at least one question, if not two, where the names will be Amazon Web Services names and not Google’s. And I did this on purpose just to throw it in there. As a result, connect directly. This is actually an Amazon Web service. Cloud VPCs communicate directly with a cloud. IAM. So which one do you think it is? So, once again, let me just walk you through the service and then we’ll move on to networking. Interconnect. Okay, so we go down more, right? We’re thinking about identity and security, right? We start with Cloud IAM and then move on to the interconnect. I just don’t know why I lost my place there, but I did. Okay, so clouds interconnect. Okay, so VPC What is VPC? This is managed networking. This is intended to connect you to Google Cloud. It’s a private virtual cloud.
However, let’s go back. Is this a direct physical connection? No, it is not. This is a shared VPC, right? So it’s not a direct connection. Let’s go over to Internet Connect, and that will be the right answer because, again, this is basically how you’re going to connect to Google’s Network Edge with an enterprise-grade interconnect. And, once again, this is essentially “direct peering.” And they also call it “Cloud Interconnect” as well. So this would be the proper feature to use. Again, this is a naming convention issue. This is what you would use to connect to the cloud’s virtual network edge. So this is another confusing sort of area. So, once again, I did it on purpose because they basically asked you to do it in a direct manner. To make that work, you must perform a direct tier. Cloud VPC won’t actually work. Direct Connect is actually what it is: an Amazon On service. Then IAM will be clouded. Right. This is actually for identity management. So again, this is part of the gig there. Okay, so with that said, let’s continue on.
