Which of the following best explains why AI output could be inaccurate?

  1. Model poisoning
  2. Social engineering
  3. Output handling
  4. Prompt injections

Answer(s): A

Explanation:

Model poisoning involves deliberately feeding malicious or biased data into an AI model during training, leading to inaccurate or manipulated outputs. It directly affects the model's behavior and reliability.



A company runs a DAST scan on a web application. The tool outputs the following recommendations:


- Use Cookie prefixes.

- Content Security Policy - SameSite=strict is not set.

Which of the following vulnerabilities has the tool identified?

  1. RCE
  2. XSS
  3. CSRF
  4. TOCTOU

Answer(s): C

Explanation:

The recommendations to use Cookie prefixes and set SameSite=strict relate directly to mitigating Cross-Site Request Forgery (CSRF) attacks by restricting how cookies are sent with cross-site requests.



Which of the following best describes the reason a network architect would enable forward secrecy on all VPN tunnels?

  1. This process is a requirement to enable hardware-accelerated cryptography.
  2. This process reduces the success of attackers performing cryptanalysis.
  3. The business requirements state that confidentiality is a critical success factor.
  4. Modern cryptographic protocols list this process as a prerequisite for use.

Answer(s): B

Explanation:

Forward secrecy ensures that even if long-term private keys are compromised, past session keys remain secure. This reduces the success of attackers performing cryptanalysis on captured encrypted traffic.



Which of the following best explains the importance of determining organizational risk appetite when operating with a constrained budget?

  1. Risk appetite directly impacts acceptance of high-impact, low-likelihood events.
  2. Organizational risk appetite varies from organization to organization.
  3. Budgetary pressure drives risk mitigation planning in all companies.
  4. Risk appetite directly influences which breaches are disclosed publicly.

Answer(s): A

Explanation:

Risk appetite defines the level of risk an organization is willing to accept.
When budgets are constrained, understanding this threshold is essential to prioritize resources and determine whether to accept, mitigate, or transfer high-impact, low-likelihood risks.



A company hired an email service provider called my-email.com to deliver company emails. The company started having several issues during the migration. A security engineer is troubleshooting and observes the following configuration snippet:



Which of the following should the security engineer modify to fix the issue? (Choose two.)

  1. The email CNAME record must be changed to a type A record pointing to 192.168.1.11
  2. The TXT record must be changed to "v=dmarc ip4:192.168.1.10 include:my-email.com ~all"
  3. The srv01 A record must be changed to a type CNAME record pointing to the email server
  4. The email CNAME record must be changed to a type A record pointing to 192.168.1.10
  5. The TXT record must be changed to "v=dkim ip4:192.168.1.11 include:my-email.com ~all"
  6. The TXT record must be changed to "v=spf ip4:192.168.1.10 include:my-email.com ~all"
  7. The srv01 A record must be changed to a type CNAME record pointing to the web01 server

Answer(s): D,F

Explanation:

The email CNAME currently points to srv01.company.com, which resolves to an internal IP (192.168.1.10). For proper mail delivery through the external provider, this should be replaced with an A record pointing directly to the correct public IP or provider's mail server.
The TXT record shown is a DMARC record, but to authorize the external email provider (my-email.com), an SPF (Sender Policy Framework) record must be configured using:
"v=spf1 ip4:192.168.1.10 include:my-email.com ~all"
