,1. Question:
Which of the following protocols is used to provide network
communications through the encapsulation of packets within the
same transport layer protocol?
- A) IPsec
- B) GRE
- C) L2TP
- D) MPLS
Answer: B) GRE
Rationale: GRE (Generic Routing Encapsulation) is used to
encapsulate a wide variety of network layer protocols inside
virtual point-to-point links.
2. Question:
In a Network Function Virtualization (NFV) environment,
which component is responsible for orchestrating and managing
resources?
- A) Virtual Network Function (VNF)
- B) NFV Infrastructure (NFVI)
- C) NFV Orchestrator
- D) Element Management System (EMS)
Answer: C) NFV Orchestrator
Rationale: The NFV Orchestrator manages the lifecycle of
network services and coordinates resources in an NFV
environment.
3. Question:
Segment Routing primarily operates at which layer of the OSI
model?
©2024/2025
, - A) Layer 2
- B) Layer 3
- C) Layer 4
- D) Layer 7
Answer: B) Layer 3
Rationale: Segment Routing operates at Layer 3 (Network
Layer) and leverages the IP/MPLS functionalities.
4. Question:
In Software-Defined Networking (SDN), which part of the
architecture is responsible for defining the network behavior via
programming?
- A) Data Plane
- B) Control Plane
- C) Application Plane
- D) Management Plane
Answer: B) Control Plane
Rationale: The Control Plane in SDN is responsible for
network behavior, programming, and defining routing rules.
5. Question:
Which of the following is not a benefit of Network Slicing in
5G networks?
- A) Improved Bandwidth Utilization
- B) Increased Latency
- C) Customizable Network Services
- D) Enhanced Isolation of Services
Answer: B) Increased Latency
Rationale: Network Slicing aims to reduce latency, not
increase it, along with improving bandwidth utilization and
