,1. Which of the following protocols is most susceptible to a
man-in-the-middle attack if not properly secured?
a) OSPF
b) RIP
c) EIGRP
d) BGP
Answer: d) BGP
Rationale: BGP is used for inter-domain routing and
relies heavily on trust. Without proper security measures
like TCP MD5 signature option or BGPsec, it can be
susceptible to attacks.
2. What is the primary purpose of implementing VLAN
Access Control Lists (VACLs) in a network?
a) Ensuring data integrity
b) Filtering traffic within a VLAN
c) Preventing data packet loss
d) Securing routing protocols
Answer: b) Filtering traffic within a VLAN
Rationale: VACLs are used to filter traffic within a
VLAN, applying security policies to frames traversing the
VLAN.
3. Which type of attack does Dynamic ARP Inspection
(DAI) help mitigate?
Answer: b) ARP Spoofing
Rationale: DAI validates ARP packets on the network,
helping to prevent ARP spoofing attacks.
4. In a secure network, what is the most effective way to
prevent unauthorized access to switch management
interfaces?
a) Applying VLANs
b) Using SSH instead of Telnet
c) Configuring port security
d) Utilizing a DMZ
Answer: b) Using SSH instead of Telnet
Rationale: SSH encrypts the management traffic,
reducing the risk of interception, whereas Telnet transmits
data in plaintext.

a secure connection for BGP sessions?
