Question 100

During an application modernization project at Atlas Scientific, engineers say that they resolved this finding: A file integrity workflow uses reversible encryption as its only proof that a downloaded update was unmodified. Which result provides the STRONGEST acceptance evidence?

  1. Credential storage contains salted adaptive hashes rather than plaintext or fast unsalted digests.
  2. A tunnel behind NAT establishes and carries protected traffic without ESP being dropped.
  3. The negotiated security associations protect bidirectional traffic and are visible in VPN status.
  4. A tampered update fails signature validation while the authentic package validates.

Explanation

Correct Answer

D:

A tampered update fails signature validation while the authentic package validates. This is the decisive evidence for the original problem: A file integrity workflow uses reversible encryption as its only proof that a downloaded update was unmodified. It verifies that the intended corrective control—Use a cryptographic digest and verified digital signature for integrity and publisher authenticity—works in the relevant environment; a completed change ticket alone would not prove the outcome at Atlas Scientific.

Incorrect Answers

A:

Credential storage contains salted adaptive hashes rather than plaintext or fast unsalted digests. This would be relevant evidence for a different failure: A security team assumes a fast general-purpose hash can safely protect stored user passwords by itself, usually addressed by Use an adaptive password-hashing function with unique salts and suitable work factors. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: A tampered update fails signature validation while the authentic package validates.

B:

A tunnel behind NAT establishes and carries protected traffic without ESP being dropped. This would be relevant evidence for a different failure: A NAT gateway changes IPsec peer addresses and native ESP traffic fails through the path, usually addressed by Use supported IPsec NAT traversal with UDP encapsulation and matching peer configuration. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: A tampered update fails signature validation while the authentic package validates.

C:

The negotiated security associations protect bidirectional traffic and are visible in VPN status. This would be relevant evidence for a different failure: Two remote offices require confidentiality and authenticated integrity for traffic traversing the public Internet, usually addressed by Configure standards-based IPsec using appropriate IKE authentication and encryption proposals. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: A tampered update fails signature validation while the authentic package validates.

Question 101

At Pinecrest Research, during a security incident tabletop exercise, the security team is examining research data and distributed collaboration. The finding is: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings. Which action BEST addresses this specific security issue?

  1. Use a cryptographic digest and verified digital signature for integrity and publisher authenticity.
  2. Configure standards-based IPsec using appropriate IKE authentication and encryption proposals.
  3. Use supported IPsec NAT traversal with UDP encapsulation and matching peer configuration.
  4. Deploy a valid certificate chain for the service name and enforce normal certificate validation.

Explanation

Correct Answer

D:

Deploy a valid certificate chain for the service name and enforce normal certificate validation. This directly addresses the documented failure: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings. For the Pinecrest Research environment, the measurable success condition is: Clients reject an untrusted chain while the correct service certificate succeeds. This control targets the specific failure rather than merely changing an unrelated security setting.

Incorrect Answers

A:

Use a cryptographic digest and verified digital signature for integrity and publisher authenticity. That action fits another problem: A file integrity workflow uses reversible encryption as its only proof that a downloaded update was unmodified. It does not directly remediate the current finding at Pinecrest Research: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings. The relevant corrective control for this case is: Deploy a valid certificate chain for the service name and enforce normal certificate validation.

B:

Configure standards-based IPsec using appropriate IKE authentication and encryption proposals. That action fits another problem: Two remote offices require confidentiality and authenticated integrity for traffic traversing the public Internet. It does not directly remediate the current finding at Pinecrest Research: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings.

It does not directly remediate the current finding at Pinecrest Research: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings. The relevant corrective control for this case is: Deploy a valid certificate chain for the service name and enforce normal certificate validation.

Question 102

At Pinecrest Research, a team reports that it corrected the following problem affecting research data and distributed collaboration: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings. Which observation BEST verifies that the correction actually worked?

  1. A tunnel behind NAT establishes and carries protected traffic without ESP being dropped.
  2. A tampered update fails signature validation while the authentic package validates.
  3. Clients reject an untrusted chain while the correct service certificate succeeds.
  4. The negotiated security associations protect bidirectional traffic and are visible in VPN status.

Explanation

Question 103

A security engineer at Briarwood Property Group reviews tenant applications and facility services as part of a scheduled security controls review. The observed problem is: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings. What is the BEST corrective action?

  1. Use an adaptive password-hashing function with unique salts and suitable work factors.
  2. Inventory vulnerable algorithms and plan interoperable standards-based post-quantum or hybrid migration.
  3. Use supported IPsec NAT traversal with UDP encapsulation and matching peer configuration.
  4. Deploy a valid certificate chain for the service name and enforce normal certificate validation.

Explanation

Correct Answer

D:

Deploy a valid certificate chain for the service name and enforce normal certificate validation. This directly addresses the documented failure: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings. For the Briarwood Property Group environment, the measurable success condition is: Clients reject an untrusted chain while the correct service certificate succeeds. This control targets the specific failure rather than merely changing an unrelated security setting.

Incorrect Answers

The relevant corrective control for this case is: Deploy a valid certificate chain for the service name and enforce normal certificate validation.

B:

Inventory vulnerable algorithms and plan interoperable standards-based post-quantum or hybrid migration. That action fits another problem: A long-lived cryptographic system has no plan for migration to quantum-resistant key establishment. It does not directly remediate the current finding at Briarwood Property Group: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings. The relevant corrective control for this case is: Deploy a valid certificate chain for the service name and enforce normal certificate validation.

C:

Question 104

During a scheduled security controls review at Briarwood Property Group, engineers say that they resolved this finding: A site serves TLS with a certificate from an untrusted issuer and clients bypass warnings. Which result provides the STRONGEST acceptance evidence?

  1. Credential storage contains salted adaptive hashes rather than plaintext or fast unsalted digests.
  2. A controlled pilot negotiates supported algorithms and documents rollback and interoperability.
  3. Clients reject an untrusted chain while the correct service certificate succeeds.
  4. A tunnel behind NAT establishes and carries protected traffic without ESP being dropped.
