SECTION 1: Network Infrastructure Security
Question 1
A medium-sized e-commerce company plans to implement a load balancer to
manage increased web traffic. The network administrator must ensure the load
balancer is configured according to security best practices to reduce the attack
surface. What is the most critical security measure the administrator should
implement?
A) Implement a Web Application Firewall alongside the load balancer
B) Disable all unused ports and services on the load balancer
C) Configure the load balancer in active-passive mode
D) Enable SSL/TLS encryption for all traffic passing through the load balancer
Answer: B) Disable all unused ports and services on the load balancer
Rationale: Disabling unused ports and services is the most fundamental step in
reducing the attack surface of any network device. This principle of least
functionality ensures that only necessary services are running, minimizing
potential entry points for attackers. While the other options provide security
benefits, they build upon the foundation of reducing the attack surface by
eliminating unnecessary services.
Question 2
An organization is redesigning its network infrastructure to improve security. The
IT manager is considering implementing both an Intrusion Prevention System
(IPS) and an Intrusion Detection System (IDS). Which deployment method would
provide the most comprehensive protection while maintaining network
performance?
A) Deploy both IPS and IDS in passive mode at the network perimeter
B) Deploy the IDS in inline mode and IPS in passive mode
C) Deploy the IPS in inline mode and IDS in passive mode at the network
,perimeter
D) Deploy both devices in inline mode at the network core
Answer: C) Deploy the IPS in inline mode and IDS in passive mode at the
network perimeter
Rationale: This deployment strategy provides comprehensive protection by
placing the IPS inline to actively block threats and the IDS in passive mode to
monitor and alert on suspicious activity without impacting traffic flow. The
network perimeter is the ideal location for these devices as it provides visibility
into both inbound and outbound traffic. This approach balances security
effectiveness with network performance considerations.
Question 3
A network engineer needs to analyze packet data to verify that application
protocols correspond to their assigned ports and track session states to prevent
fraudulent session initiations. Which security tool should the engineer prioritize
deploying?
A) Stateful firewall
B) Deep packet inspection firewall
C) Proxy server
D) Network address translation (NAT) device
Answer: B) Deep packet inspection firewall
Rationale: Deep packet inspection (DPI) firewalls examine the actual content of
packets, including application-layer data, to verify that protocols match their
assigned ports. DPI firewalls also maintain session state information and can detect
and prevent fraudulent session initiations by analyzing the complete context of
network communications. This makes them superior to traditional stateful firewalls
for application-aware security.
Question 4
, A large enterprise is implementing a Next Generation Firewall (NGFW) as part of
its defense strategy. The organization mixes internal and external services,
including web applications and VPN access. How should the administrator deploy
the NGFW to ensure effective security without disrupting normal operations?
A) Deploy the NGFW in passive monitoring mode only
B) Deploy the NGFW in inline mode, analyzing all traffic while maintaining
connectivity
C) Deploy the NGFW as a transparent bridge between the core and distribution
layers
D) Deploy the NGFW in parallel with the existing firewall infrastructure
Answer: B) Deploy the NGFW in inline mode, analyzing all traffic while
maintaining connectivity
Rationale: Inline deployment allows the NGFW to actively inspect and block
threats in real-time while maintaining network connectivity. This provides the
maximum security benefit by enabling all security features including application
identification, user identification, and threat prevention. The NGFW's advanced
capabilities, such as application-layer filtering and intrusion prevention, function
optimally when operating inline.
Question 5
A network security team wants to implement zone-based security across their
organization. When designing the security zones, which principle should guide the
placement of hosts with similar access requirements?
A) Hosts with similar functions should be placed in different zones for redundancy
B) Hosts with different security requirements should be placed in the same zone
for efficiency
C) Hosts within the same zone should be subject to the same access control
requirements
D) Hosts should be assigned to zones based solely on their physical location
Answer: C) Hosts within the same zone should be subject to the same access
control requirements
