IT 210 Enterprise Network Engineering
Comprehensive Final Exam (Qns & Ans)
2025
Question 1 (Multiple Choice)
Question:
Which of the following features most clearly distinguishes
Software-Defined Networking (SDN) within an enterprise
network compared to traditional networking architectures?
A) Distributed control plane managed by individual switches
B) Centralized control that decouples the control plane from the
data plane
C) Reliance on static routing tables hard-coded into hardware
D) Use of proprietary protocols exclusively for routing
Correct ANS:

,B) Centralized control that decouples the control plane from the
data plane
Rationale:
SDN’s centralization means that a central controller makes
decisions and pushes policies to the underlying devices. This
decoupling allows for dynamic network provisioning, easier
management, and rapid response to changes, in contrast to
traditional, hardware-centric, distributed control approaches.

Question 2 (Fill in the Blank)
Question:
The process of dividing an IP address space into smaller, more
manageable segments is known as ________ .
Correct ANS:
subnetting
Rationale:
Subnetting breaks a large network into sub-networks (subnets),
which improves management, enhances security by isolating

,broadcast domains, and optimizes address allocation in enterprise
networks.

Question 3 (True/False)
Question:
True/False: Multiprotocol Label Switching (MPLS) is primarily
used in enterprise networks to accelerate packet forwarding and
support scalable Virtual Private Networks (VPNs).
Correct ANS:
True
Rationale:
MPLS assigns short labels to packets, allowing routers to forward
them quickly without performing full IP lookups. Additionally,
MPLS supports scalable VPN solutions by isolating traffic among
different customer networks on a common infrastructure.

, Question 4 (Multiple Response)
Question:
Select all components that are typically part of a hierarchical
enterprise network design model:
A) Core layer
B) Distribution layer
C) Access layer
D) Application layer
E) Internet layer
Correct ANS:
A, B, C
Rationale:
A hierarchical network design in enterprise environments
commonly comprises the core, distribution, and access layers.
These layers help organize the network for optimal performance,
scalability, and ease of management. The application and Internet
layers are not specific to the physical or logical network design in
this model.
