Question: 1 
   
A recent zero-day vulnerability is being actively exploited, requires no user interaction or privilege 
escalation, and has a significant impact to confidentiality and integrity but not to availability. Which of 
the following CVE metrics would be most accurate for this zero-day threat? 
 
A. CVSS: 31/AV: N/AC: L/PR: N/UI: N/S: U/C: H/1: K/A: L 
B. CVSS:31/AV:K/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:L 
C. CVSS:31/AV:N/AC:L/PR:N/UI:H/S:U/C:L/I:N/A:H 
D. CVSS:31/AV:L/AC:L/PR:R/UI:R/S:U/C:H/I:L/A:H 
 
Answer: A     
 
Explanation: 
This answer matches the description of the zero-day threat. The attack vector is network (AV:N), the 
attack complexity is low (AC:L), no privileges are required (PR:N), no user interaction is required (UI:N), 
the scope is unchanged (S:U), the confidentiality and integrity impacts are high (C:H/I:H), and the 
availability impact is low (A:L). Official Reference: https://nvd.nist.gov/vuln-metrics/cvss 
 
Question: 2 
   
Which of the following tools would work best to prevent the exposure of PII outside of an organization? 
 
A. PAM 
B. IDS 
C. PKI 
D. DLP 
 
Answer: D     
 
Explanation: 
Data loss prevention (DLP) is a tool that can prevent the exposure of PII outside of an organization by 
monitoring, detecting, and blocking sensitive data in motion, in use, or at rest.

Which of the following tuning recommendations should the security analyst share? 
 
A. Set an HttpOnlvflaq to force communication by HTTPS 
B. Block requests without an X-Frame-Options header 
C. Configure an Access-Control-Allow-Origin header to authorized domains 
D. Disable the cross-origin resource sharing header 
 
Answer: B     
 
Explanation: 
The output shows that the web application is vulnerable to clickjacking attacks, which allow an attacker 
to overlay a hidden frame on top of a legitimate page and trick users into clicking on malicious links. 
Blocking requests without an X-Frame-Options header can prevent this attack by instructing the browser 
to not display the page within a frame. 
 
Question: 4

A. Lessons learned 
B. Service-level agreement

F. Education plan 
 
Answer: D, E     
 
Explanation: 
A vulnerability scan report should include information about the affected hosts, such as their IP 
addresses, hostnames, operating systems, and services. It should also include a risk score for each 
vulnerability, which indicates the severity and potential impact of the vulnerability on the host and the 
organization. Official Reference: https://www.first.org/cvss/ 
 
Question: 5 
   
The Chief Executive Officer of an organization recently heard that exploitation of new attacks in the 
industry was happening approximately 45 days after a patch was released. Which of the following would 
best protect this organization? 
 
A. A mean time to remediate of 30 days 
B. A mean time to detect of 45 days 
C. A mean time to respond of 15 days 
D. Third-party application testing 
 
Answer: A     
 
Explanation: 
A mean time to remediate (MTTR) is a metric that measures how long it takes to fix a vulnerability after 
it is discovered. A MTTR of 30 days would best protect the organization from the new attacks that are 
exploited 45 days after a patch is released, as it would ensure that the vulnerabilities are fixed before 
they are exploited
