1. Which security architecture model assumes no implicit trust for
any user or device?
A. Bell-LaPadula
B. Clark-Wilson
C. Zero Trust
D. Biba
Answer: C. Zero Trust
Rationale: Zero Trust requires continuous verification of every user,
device, and application regardless of location.
2. Which principle grants users only the permissions necessary to
perform their job?
A. Separation of duties
B. Job rotation
C. Least privilege
D. Need to share
Answer: C. Least privilege
,Rationale: Least privilege minimizes attack surfaces by limiting
unnecessary access.
3. Which architecture component separates internal networks from
external networks?
A. IDS
B. Proxy
C. Firewall
D. Load balancer
Answer: C. Firewall
Rationale: Firewalls enforce security policies by filtering traffic
between networks.
4. What is the primary purpose of network segmentation?
A. Increase bandwidth
B. Improve DNS performance
C. Limit attack spread
D. Compress traffic
Answer: C. Limit attack spread
Rationale: Segmentation isolates systems, reducing lateral
movement by attackers.
5. Which technology authenticates devices before network access is
granted?
A. SSH
B. NAT
C. 802.1X
D. SMTP
,Answer: C. 802.1X
Rationale: IEEE 802.1X provides port-based network access control.
6. Which architecture places public-facing servers between internal
and external networks?
A. VLAN
B. VPN
C. DMZ
D. SAN
Answer: C. DMZ
Rationale: A DMZ isolates public services from the internal network.
7. Which architecture concept distributes workloads across
multiple servers?
A. Proxy
B. NAT
C. Load balancing
D. Sandboxing
Answer: C. Load balancing
Rationale: Load balancing improves performance and availability.
8. Which security architecture component inspects encrypted
HTTPS traffic?
A. Switch
B. Hub
C. SSL/TLS inspection appliance
D. Repeater
, Answer: C. SSL/TLS inspection appliance
Rationale: SSL inspection decrypts, analyzes, and re-encrypts secure
traffic.
9. Which design principle assumes systems will eventually fail?
A. Defense in depth
B. Trust but verify
C. Fail securely
D. Availability
Answer: C. Fail securely
Rationale: Secure failure prevents unauthorized access during
outages.
10. Which architecture strategy uses multiple overlapping security
controls?
A. High availability
B. Defense in depth
C. Thin client
D. Containerization
Answer: B. Defense in depth
Rationale: Multiple security layers provide redundancy against
attacks.
11. Which network architecture isolates broadcast domains?
A. Hub
B. VLAN
