,1. What is the primary benefit of using OSPF over RIP in
large scale networks?
- A) Faster convergence
- B) Easier configuration
- C) Less CPU usage
- D) Smaller routing tables
Answer: A) Faster convergence
Rationale : OSPF provides faster convergence than RIP
due to its link-state nature, which allows it to quickly
propagate changes to network topology.
2. Which type of BGP attribute is used to determine the
preferred path among multiple routes with identical
prefixes?
- A) AS-PATH
- B) Next-hop
- C) Local-preference
- D) MED (Multi-Exit Discriminator)
Answer: C) Local-preference
Rationale : Local-preference is a BGP attribute used to
prioritize routes within an AS when choosing between
multiple paths.
3. In MPLS, what is the function of an LSR (Label
Switching Router)?
- A) Label distribution
- B) Traffic policing
- C) Traffic shaping
- D) Route aggregation
©2024/2025
, Answer: A) Label distribution
Rationale : LSRs are responsible for forwarding packets
based on labels and distributing these labels throughout the
MPLS network.
4. Which switching technology can combine multiple
physical links into a single logical link?
- A) Ethernet Channel
- B) VLAN
- C) LACP (Link Aggregation Control Protocol)
- D) STP (Spanning Tree Protocol)
Answer: C) LACP (Link Aggregation Control Protocol)
Rationale : LACP is used to bundle several physical ports
to form a single logical channel, increasing availability and
bandwidth.
5. When configuring HSRP, which router becomes the
active router by default?
- A) Router with the lowest IP address
- B) Router with the highest IP address
- C) Router with the highest priority
- D) Router with the lowest priority
Answer: C) Router with the highest priority
Rationale : HSRP elects the router with the highest
configured priority as the active router.

6. In OSPF, an area that does not accept external routes
from one or more areas is known as an __________.
