Spanning All Eight Core Network Defense Domains
to Ensure Success
Domain 1: Network Defense Management (10%)
Question 1
Which statement BEST describes defense in depth?
• A. Using one perimeter firewall as the primary
security control
• B. Applying multiple layered controls so that
one failure does not expose the entire
environment
• C. Encrypting every packet on the network with
the same shared key
,2
• D. Blocking all outbound traffic from user
workstations
☑VERIFIED ANSWER: B

controls at different layers. If one control fails, other
controls still reduce the chance of compromise or
limit impact.
Question 2
Which of the following is true regarding any attack
surface?
• A. The attack surface refers to the sum of all
potential points where an unauthorized user
can try to enter or extract data
• B. The attack surface is only related to physical
access points
• C. The attack surface cannot be reduced
,3
• D. The attack surface only includes software
vulnerabilities
☑VERIFIED ANSWER: A
Rationale: The attack surface encompasses all
vulnerabilities, including software flaws, unsecured
network ports, and unprotected system endpoints.
When vulnerabilities are decreased, the attack
surface is reduced.
Question 3
Which Internet access policy starts with all services
blocked and the administrator enables safe and
necessary services individually?
• A. Permissive policy
• B. Paranoid policy
• C. Prudent policy
• D. Promiscuous policy

approach minimizes potential vulnerabilities.
Question 4
Management decides to implement a risk
management system to reduce and maintain the
organization's risk at an acceptable level. What is
the correct order in the risk management phase?
• A. Risk assessment → Risk mitigation → Risk
evaluation → Risk monitoring
• B. Risk identification → Risk analysis → Risk
evaluation → Risk treatment
• C. Risk planning → Risk execution → Risk review
→ Risk closure
• D. Risk discovery → Risk classification → Risk
response → Risk audit
