Question 660

At Timberline Foods, the supply-chain assurance team is conducting a coordinated processing-plant assessment under requirements for food safety and secure logistics. Following the approved correction, auditors require proof that: A mobile app relies on a custom TLS certificate check that accepts every server certificate during testing and remains enabled in production. Which result BEST demonstrates successful remediation?

  1. After logout the cache no longer exposes customer records to an unauthorized local test account.
  2. The app connects to its valid service and rejects a test server with an untrusted certificate.
  3. An unapproved app installation is blocked and the managed work profile contains only approved applications.
  4. A diagnostic capture contains no reusable token and an app restart retains only securely stored session state.

Explanation

Correct Answer

B:

The app connects to its valid service and rejects a test server with an untrusted certificate. The observable result demonstrates that the documented condition, A mobile app relies on a custom TLS certificate check that accepts every server certificate during testing and remains enabled in production. has been addressed. The planned remediation is: Validate trusted server certificates through supported platform TLS verification and remove permissive debug exceptions. This is a stronger validation than a saved ticket or unverified claim by Timberline Foods.

Incorrect Answers

A:

After logout the cache no longer exposes customer records to an unauthorized local test account. That observation would verify another scenario: A mobile app stores private customer records in unencrypted local cache files that survive user logout. The corrective step for that other scenario is: Encrypt sensitive local storage and clear session-bound data on logout under the device's data-protection controls. But Timberline Foods is evaluating: A mobile app relies on a custom TLS certificate check that accepts every server certificate during testing and remains enabled in production. The necessary outcome is: The app connects to its valid service and rejects a test server with an untrusted certificate.

C:

An unapproved app installation is blocked and the managed work profile contains only approved applications. That observation would verify another scenario: A managed Android fleet permits installation from unapproved package sources despite a corporate policy requiring vetted applications. The corrective step for that other scenario is: Enforce managed application allowlists, OS update compliance and work-profile separation through mobile device management. But Timberline Foods is evaluating: A mobile app relies on a custom TLS certificate check that accepts every server certificate during testing and remains enabled in production. The necessary outcome is: The app connects to its valid service and rejects a test server with an untrusted certificate.

D:

A diagnostic capture contains no reusable token and an app restart retains only securely stored session state. That observation would verify another scenario: A mobile application writes authentication tokens into a world-readable debug log on the device. The corrective step for that other scenario is: Remove secrets from logs and use platform-protected token storage with suitable expiration and revocation. But Timberline Foods is evaluating: A mobile app relies on a custom TLS certificate check that accepts every server certificate during testing and remains enabled in production. The necessary outcome is: The app connects to its valid service and rejects a test server with an untrusted certificate.

Question 661

At Juniper Media, the digital-platform security team is conducting a scoped content-delivery assessment under requirements for rights enforcement and safe media workflows. Assessors report the following documented condition: A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. Which action BEST addresses the documented security gap?

  1. Remove secrets from logs and use platform-protected token storage with suitable expiration and revocation.
  2. Use phishing-resistant MFA or number matching, prompt throttling and a clear unexpected-request reporting process.
  3. Review mobile permissions, remove unnecessary entitlements and require just-in-time consent for legitimate capabilities.
  4. Use server-side risk checks and platform-supported app or device integrity signals without treating them as the only authorization condition.

Explanation

Correct Answer

B:

Use phishing-resistant MFA or number matching, prompt throttling and a clear unexpected-request reporting process. This directly addresses the authorized assessment finding: A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. The Juniper Media team should verify the outcome rather than treat a configuration edit as proof. Acceptance evidence: An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation.

Incorrect Answers

A:

Remove secrets from logs and use platform-protected token storage with suitable expiration and revocation. This is an appropriate control for a different issue: A mobile application writes authentication tokens into a world-readable debug log on the device. The Juniper Media finding instead concerns: A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. It does not demonstrate the required correction. The decisive test remains: An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation.

C:

Review mobile permissions, remove unnecessary entitlements and require just-in-time consent for legitimate capabilities. This is an appropriate control for a different issue: A corporate iOS app uses broad background permissions for location and microphone even though its business function requires neither. The Juniper Media finding instead concerns: A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. It does not demonstrate the required correction. The decisive test remains: An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation.

D:

Use server-side risk checks and platform-supported app or device integrity signals without treating them as the only authorization condition. This is an appropriate control for a different issue: A banking app trusts a user-provided client device identifier as proof that the phone has not been compromised. The Juniper Media finding instead concerns: A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. It does not demonstrate the required correction. The decisive test remains: An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation.

Question 662

At Juniper Media, the digital-platform security team is conducting a scoped content-delivery assessment under requirements for rights enforcement and safe media workflows. The team now needs objective retest evidence for: A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. Which result BEST demonstrates successful remediation?

  1. The app operates its approved workflow without unused microphone or background location access.
  2. A noncompliant test device is flagged or quarantined despite showing the latest OS patch version.
  3. An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation.
  4. An altered device identifier does not bypass transaction authorization and anomalous device posture raises a review event.

Explanation

Correct Answer

C:

An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation. The observable result demonstrates that the documented condition, A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. has been addressed.

The necessary outcome is: An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation.

B:

A noncompliant test device is flagged or quarantined despite showing the latest OS patch version. That observation would verify another scenario: An endpoint team equates a successful mobile OS update with a fully secure device even though an unapproved sideloaded app persists. The corrective step for that other scenario is: Combine patch compliance with application inventory, configuration posture and policy attestation. But Juniper Media is evaluating: A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. The necessary outcome is: An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation.

Question 663

At Meadowbrook Finance, the banking cyber assurance team is conducting a controlled financial-services security review under requirements for auditability and transaction integrity. The control assessment finds: A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. Which action BEST addresses the documented security gap?

  1. Use phishing-resistant MFA or number matching, prompt throttling and a clear unexpected-request reporting process.
  2. Enforce object-level server authorization for every mobile API endpoint and use the UI only for presentation.
  3. Encrypt sensitive local storage and clear session-bound data on logout under the device's data-protection controls.
  4. Validate trusted server certificates through supported platform TLS verification and remove permissive debug exceptions.

Explanation

Correct Answer

A:

The Meadowbrook Finance team should verify the outcome rather than treat a configuration edit as proof. Acceptance evidence: An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation.

Incorrect Answers

B:

Enforce object-level server authorization for every mobile API endpoint and use the UI only for presentation. This is an appropriate control for a different issue: A mobile API gives a user access to another customer's record because the app hides the other record in its UI but the API does not check ownership. The Meadowbrook Finance finding instead concerns: A push-approval login asks users to approve many unexpected sign-in prompts and the help desk has no reporting workflow. It does not demonstrate the required correction. The decisive test remains: An unsolicited approval prompt cannot authorize a session and users can report repeated prompts for investigation.
