CompTIA Network+ N10-009 Practice Test 65

Question 640

An application queries user attributes from a corporate directory. Which diagnostic or verification check MOST directly evaluates the expected network behavior in this situation?

  1. Verify a directory object exists but never query under the intended least-privilege identity
  2. Check that TCP/389 responds without assessing allowed attributes or TLS protection
  3. Test a highly privileged admin bind and infer ordinary applications are correctly restricted
  4. Test least-privilege query returns only authorized entries

Explanation

Correct Answer

D:

LDAP directory queries do not automatically prove interactive login. The result of the remedy is checked directly: Test least-privilege query returns only authorized entries.

Incorrect Answers

A:

Verify a directory object exists but never query under the intended least-privilege identity. LDAP directory queries do not automatically prove interactive login. The appropriate acceptance test is: Test least-privilege query returns only authorized entries.

B:

Check that TCP/389 responds without assessing allowed attributes or TLS protection. LDAP directory queries do not automatically prove interactive login. The appropriate acceptance test is: Test least-privilege query returns only authorized entries.

Question 641

A SaaS app exchanges identity assertions with the corporate IdP. Which response MOST directly addresses the stated network problem or requirement?

  1. Require verified SAML signature, audience and validity checks
  2. Accept a SAML assertion with a valid signature for a different application audience
  3. Ignore NotBefore/NotOnOrAfter validity when old assertions are replayed
  4. Disable IdP signing verification if the SaaS app can decode the XML message

Explanation

Correct Answer

A:

Federated assertion trust depends on claims validation, not just XML parsing. A direct way to confirm the outcome is to replay assertion for wrong relying party and expect rejection.

Incorrect Answers

B:

Accept a SAML assertion with a valid signature for a different application audience. Federated assertion trust depends on claims validation, not just XML parsing. This does not implement the needed approach: require verified SAML signature, audience and validity checks.

C:

Question 642

A SaaS app exchanges identity assertions with the corporate IdP. Which diagnostic or verification check MOST directly evaluates the expected network behavior in this situation?

  1. Confirm a legitimate SSO succeeds but never replay a wrong-audience assertion
  2. Replay assertion for wrong relying party and expect rejection
  3. Check assertion XML syntax without evaluating signature, audience and expiry
  4. Read IdP metadata while never testing whether the relying party rejects invalid tokens

Explanation

Correct Answer

B:

Question 643

A junior operator needs read-only switch status but not configuration privileges. Which response MOST directly addresses the stated network problem or requirement?

  1. Give the read-only junior operator write privilege to modify interface ACLs
  2. Implement a shared full-admin account instead of individual restricted roles
  3. Assign least-privilege operational role and test command-level authorization
  4. Treat command visibility as permission to execute configuration mutations

Explanation

Correct Answer

C:

Authentication establishes identity; authorization limits what it can do. A direct way to confirm the outcome is to attempt configuration write under read-only role and verify denial.

  2. Read a role name Restricted without testing effective command authorization
  3. Check login success and infer all write operations are denied automatically
  4. Attempt configuration write under read-only role and verify denial

Explanation

Correct Answer

D:

Authentication establishes identity; authorization limits what it can do. The result of the remedy is checked directly: Attempt configuration write under read-only role and verify denial.

  2. Assign permissions separately to each employee without reviewing departmental role membership
  3. Keep all former-department permissions after a staff transfer regardless of new responsibilities
  4. Grant the same highest privilege role to every SOC and sales user to avoid access requests

Explanation

Correct Answer

A:

RBAC assigns permission bundles through roles, not physical location. A direct way to confirm the outcome is to audit effective privileges before and after role transfer.

Question 647

A SaaS service is geographically restricted to authorized sales regions. Which response MOST directly addresses the stated network problem or requirement?

  1. Treat country IP geolocation as a guaranteed legal identity and block legitimate users without exception
  2. Permit all restricted-region sessions because a VPN can change the apparent IP country
  3. Use geofencing as risk signal with legitimate access exception workflow
  4. Use timezone language settings as sole proof the client belongs to an approved sales territory

Explanation

Correct Answer

C:

Geographic filtering is not strong identity authentication. A direct way to confirm the outcome is to test expected region policy and measure false location classification.

Incorrect Answers
