NVCC ITN 100 EXAM 2 — 300 RANDOMIZED PRACTICE QUESTIONS
1. A network administrator notices that users in the accounting department cannot
communicate with users in the marketing department even though both departments are
connected to the same physical network infrastructure. What is the most likely reason for this
communication failure?
A) The network cables are too long
B) The computers are using different application layer protocols
C) The network has been configured with VLANs that separate broadcast domains
D) The switches are operating at half-duplex mode
Answer: C
VLANs logically segment a network into separate broadcast domains, preventing devices in one
VLAN from communicating directly with devices in another VLAN without routing intervention.

2. When a company implements a virtual private network to connect its branch offices across
the Internet, which benefit is most significant compared to leasing dedicated circuits?
A) Higher bandwidth capacity
B) Lower cost and operational flexibility
C) Guaranteed service level agreements
D) Simpler network management
Answer: B
VPNs leverage the existing Internet infrastructure, significantly reducing costs compared to
dedicated leased lines while providing flexible connectivity options. VPNs offer high security
because they operate through the Internet—this is false; security must be added through
encryption, not inherent to the Internet itself.
3. An organization is experiencing excessive collisions on its Ethernet network. Which device,
when installed, would most effectively reduce the collision domain size?
2

A) Hub
B) Repeater
C) Switch
D) Router
Answer: C
Switches create separate collision domains for each port, isolating traffic and eliminating
collisions that occur when multiple devices share the same medium through a hub.
4. A network engineer needs to implement a routing protocol that can dynamically adapt to
network changes and automatically select alternate paths when a link fails. Which type of
routing approach is required?
A) Static routing
B) Centralized routing
C) Dynamic routing
D) Monitor routing
Answer: C
Dynamic routing protocols automatically exchange information about network topology

changes and compute optimal paths, providing fault tolerance without manual intervention.
Dynamic routing imposes an overhead cost by increasing network traffic.
5. Which statement accurately describes the difference between connection-oriented and
connectionless communication at the transport layer?
A) Connection-oriented communication does not require a session to be established
B) Connectionless communication establishes a session before data transmission
C) Connection-oriented communication uses a session to send data reliably
D) Both approaches use sessions to ensure delivery
Answer: C
Using a session to send data is called connection-oriented communication, which establishes a
logical connection before transmitting data to ensure reliable delivery. Sending messages
without establishing a session is connectionless communication.
6. A technician is troubleshooting a situation where a computer cannot communicate with
any device outside its local subnet. The IP configuration shows an address of 192.168.1.25
