Microsoft AZ-305 Practice Test 18
Question 170
An architecture proposal for vault network and encryption boundaries relies on the following approach: Grant ordinary application operators unrestricted immediate purge permission. Which specific failure or mismatch should the design reviewer identify?
- Data-service CMK integration requires explicit supported configuration.
- This inflates effective access and misses activation control.
- Irreversible purge defeats recovery safeguards.
- A public endpoint with an allowlist does not provide Private Link connectivity.
Explanation
Correct Answer
C:Grant ordinary application operators unrestricted immediate purge permission. Irreversible purge defeats recovery safeguards.
Incorrect Answers
A:That assessment refers to the separate proposal 'Assume a Key Vault secret automatically replaces every service's encryption key.' not to the recommendation under review. Here, Irreversible purge defeats recovery safeguards.
B:This concern applies to Treat every eligible assignment as permanently active when auditing privilege. in another design authentication and authorization solutions design. The current proposal specifically fails because irreversible purge defeats recovery safeguards.
D:That assessment refers to the separate proposal 'Add an outbound Internet allowlist and call the path private.' not to the recommendation under review. Here, Irreversible purge defeats recovery safeguards.
Question 171
Acceptance testing must establish the following operational result: Recovery evidence verifies deleted secret versions can be restored under policy. Which verification action most directly establishes that outcome?
- Inspect the resource's encryption configuration and key usage audit.
- Resolve vault DNS from the subnet and test network path and authorized retrieval.
- Run an authorized recovery test in a nonproduction vault.
- Test a protected operation before and during approved activation.
Explanation
Correct Answer
C:Recovery evidence verifies deleted secret versions can be restored under policy.
Incorrect Answers
A:That verification addresses the different requirement: An organization needs customer-managed encryption keys for a supported Azure data service. It does not directly establish recovery evidence verifies deleted secret versions can be restored under policy.
B:That verification addresses the different requirement: A restricted VM subnet must retrieve vault secrets without public network exposure. It does not directly establish recovery evidence verifies deleted secret versions can be restored under policy.
D:This is a test for A user claims PIM eligibility itself grants immediate permission to delete production resources. The requirement here is instead demonstrated by run an authorized recovery test in a nonproduction vault.
Question 172
Remote employees need SSO to an on-premises web app without opening inbound firewall ports. Which Azure architecture choice best meets this requirement?
- Assume an OAuth bearer token can be passed unmodified as a Kerberos ticket.
- Replace MFA with network subnet trust alone.
- Design Microsoft Entra application proxy with appropriate preauthentication and connector placement.
- Publish the app directly on public HTTP with no identity preauthentication.
Explanation
Correct Answer
C:Outbound connectors can publish eligible private web applications through managed identity controls.
Incorrect Answers
A:OAuth tokens are not native Kerberos tickets. In the present requirement, remote employees need SSO to an on-premises web app without opening inbound firewall ports. The needed design instead works because outbound connectors can publish eligible private web applications through managed identity controls.
B:IP location does not prove user possession of a strong authentication factor. In the present requirement, remote employees need SSO to an on-premises web app without opening inbound firewall ports. The needed design instead works because outbound connectors can publish eligible private web applications through managed identity controls.
D:Public unauthenticated exposure violates the controlled access requirement. This proposal contradicts the stated architecture constraint.
Question 173
An architecture proposal for authorization for on-premises and hybrid apps relies on the following approach: Publish the app directly on public HTTP with no identity preauthentication. Which specific failure or mismatch should the design reviewer identify?
- Public unauthenticated exposure violates the controlled access requirement.
- IP location does not prove user possession of a strong authentication factor.
- OAuth tokens are not native Kerberos tickets.
- Unrestricted key copies defeat hardware-backed custody and auditing.
Explanation
Correct Answer
A:Publish the app directly on public HTTP with no identity preauthentication. Public unauthenticated exposure violates the controlled access requirement.
Incorrect Answers
B:That assessment refers to the separate proposal 'Replace MFA with network subnet trust alone.' not to the recommendation under review. Here, Public unauthenticated exposure violates the controlled access requirement.
C:That assessment refers to the separate proposal 'Assume an OAuth bearer token can be passed unmodified as a Kerberos ticket.' not to the recommendation under review. Here, Public unauthenticated exposure violates the controlled access requirement.
D:This concern applies to Export the private key as a shared plaintext file to all application pods. in another design authentication and authorization solutions design. The current proposal specifically fails because public unauthenticated exposure violates the controlled access requirement.
Question 174
Acceptance testing must establish the following operational result: Assignment and policy results prove the app proxy boundary. Which verification action most directly establishes that outcome?
- Audit signing operations and verify callers cannot export nonexportable key material.
- Attempt sign-in with assigned and unassigned test users through the published URL.
- Test a user without registered MFA against the protected application.
- Test end-user SSO while checking connector delegation and SPN resolution.
Explanation
Correct Answer
B:Assignment and policy results prove the app proxy boundary.
Incorrect Answers
A:This is a test for A signing service must perform cryptographic key operations without exposing private key material. The requirement here is instead demonstrated by attempt sign-in with assigned and unassigned test users through the published URL.
C:That verification addresses the different requirement: A company plans MFA for an on-premises application while maintaining its existing directory. It does not directly establish assignment and policy results prove the app proxy boundary.
D:That verification addresses the different requirement: A hybrid workforce must sign in to a legacy Kerberos service after cloud authentication. It does not directly establish assignment and policy results prove the app proxy boundary.
Question 175
A hybrid workforce must sign in to a legacy Kerberos service after cloud authentication. Which Azure architecture choice best meets this requirement?
- Evaluate supported integrated Windows authentication or Kerberos delegation through a secure connector design.
- Replace MFA with network subnet trust alone.
- Publish the app directly on public HTTP with no identity preauthentication.
- Assume an OAuth bearer token can be passed unmodified as a Kerberos ticket.
Explanation
Correct Answer
A:Kerberos service authentication requires compatible service principals and delegation constraints.
Incorrect Answers
B:IP location does not prove user possession of a strong authentication factor. In the present requirement, a hybrid workforce must sign in to a legacy Kerberos service after cloud authentication. The needed design instead works because kerberos service authentication requires compatible service principals and delegation constraints.
C:Public unauthenticated exposure violates the controlled access requirement. In the present requirement, a hybrid workforce must sign in to a legacy Kerberos service after cloud authentication. The needed design instead works because kerberos service authentication requires compatible service principals and delegation constraints.
D:OAuth tokens are not native Kerberos tickets. This proposal contradicts the stated architecture constraint.

- Irreversible purge defeats recovery safeguards.
- OAuth tokens are not native Kerberos tickets.
Explanation
Correct Answer
D:Assume an OAuth bearer token can be passed unmodified as a Kerberos ticket. OAuth tokens are not native Kerberos tickets.
Incorrect Answers
A:That assessment refers to the separate proposal 'Publish the app directly on public HTTP with no identity preauthentication.' not to the recommendation under review. Here, OAuth tokens are not native Kerberos tickets.
B:That assessment refers to the separate proposal 'Replace MFA with network subnet trust alone.' not to the recommendation under review. Here, OAuth tokens are not native Kerberos tickets.
C:This concern applies to Grant ordinary application operators unrestricted immediate purge permission. in another design authentication and authorization solutions design. The current proposal specifically fails because oAuth tokens are not native Kerberos tickets.
Question 177

- Run an authorized recovery test in a nonproduction vault.
- Test a user without registered MFA against the protected application.
- Test end-user SSO while checking connector delegation and SPN resolution.
Explanation
Correct Answer
D:The exercise isolates on-premises ticket issuance and delegation prerequisites.
Incorrect Answers
A:That verification addresses the different requirement: Remote employees need SSO to an on-premises web app without opening inbound firewall ports. It does not directly establish the exercise isolates on-premises ticket issuance and delegation prerequisites.
B:This is a test for A critical vault must withstand operator mistakes including accidental key deletion. The requirement here is instead demonstrated by test end-user SSO while checking connector delegation and SPN resolution.
C:That verification addresses the different requirement: A company plans MFA for an on-premises application while maintaining its existing directory. It does not directly establish the exercise isolates on-premises ticket issuance and delegation prerequisites.
Question 178

- Publish the app directly on public HTTP with no identity preauthentication.
- Replace MFA with network subnet trust alone.
- Front the supported application with Entra preauthentication and Conditional Access.
- Assume an OAuth bearer token can be passed unmodified as a Kerberos ticket.
Explanation
Correct Answer
C:Cloud access controls can enforce MFA before traffic reaches the private app.
Incorrect Answers
A:Public unauthenticated exposure violates the controlled access requirement. In the present requirement, a company plans MFA for an on-premises application while maintaining its existing directory. The needed design instead works because cloud access controls can enforce MFA before traffic reaches the private app.
B:IP location does not prove user possession of a strong authentication factor. This proposal contradicts the stated architecture constraint.
D:OAuth tokens are not native Kerberos tickets. In the present requirement, a company plans MFA for an on-premises application while maintaining its existing directory. The needed design instead works because cloud access controls can enforce MFA before traffic reaches the private app.

- Public unauthenticated exposure violates the controlled access requirement.
- OAuth tokens are not native Kerberos tickets.
- Federation introduces a dependency on reachable on-premises identity infrastructure.
- IP location does not prove user possession of a strong authentication factor.
Explanation
Correct Answer
D:Replace MFA with network subnet trust alone. IP location does not prove user possession of a strong authentication factor.
Incorrect Answers
A:That assessment refers to the separate proposal 'Publish the app directly on public HTTP with no identity preauthentication.' not to the recommendation under review. Here, IP location does not prove user possession of a strong authentication factor.
B:That assessment refers to the separate proposal 'Assume an OAuth bearer token can be passed unmodified as a Kerberos ticket.' not to the recommendation under review. Here, IP location does not prove user possession of a strong authentication factor.
C:This concern applies to Require an on-premises federation service for every cloud login despite a cloud-resilience goal. in another design authentication and authorization solutions design. The current proposal specifically fails because iP location does not prove user possession of a strong authentication factor.
Question 180
