COMPTIA NETWORK+ N10-008 MOST TESTED QUESTIONS AND
ANSWERS GRADED A+ WITH RATIONALES
CompTIA Network+ N10-008 — Intensive Exam (Part 1)
1. Which device is primarily used by an end-user to access a network?
A. Server
B. Switch
C. Client
D. Router
Correct Answer: C. Client
Rationale:
A client is an endpoint device (PC, laptop, smartphone) used by end-users to access network
resources. Servers provide resources, not consume them.
2. Which device provides shared resources such as files and printers to other
devices?
A. Hub
B. Server
C. Router
D. WAP
Correct Answer: B. Server
Rationale:
A server centrally provides services and resources to client devices in a network environment.
3. Which device connects multiple network devices but may increase network
collisions due to broadcasting?
A. Switch
B. Router
,C. Hub
D. Bridge
Correct Answer: C. Hub
Rationale:
A hub broadcasts traffic to all connected ports, increasing collisions and reducing efficiency.
4. Which device learns MAC addresses and forwards frames intelligently?
A. Hub
B. Switch
C. Router
D. Modem
Correct Answer: B. Switch
Rationale:
Switches operate at Layer 2 and build a MAC address table to forward frames only to the correct
port.
5. Which device connects different networks and forwards traffic using logical IP
addresses?
A. Switch
B. Hub
C. Router
D. NIC
Correct Answer: C. Router
Rationale:
Routers operate at Layer 3 and route packets between networks based on IP addresses.
6. Which network type connects devices within a limited area such as an office
building?
A. WAN
B. MAN
, C. PAN
D. LAN
Correct Answer: D. LAN
Rationale:
A Local Area Network (LAN) connects devices within a small geographic area.
7. Which network type connects networks across a city?
A. LAN
B. PAN
C. MAN
D. CAN
Correct Answer: C. MAN
Rationale:
A Metropolitan Area Network (MAN) spans a city or metropolitan region.
8. Which topology uses a single central connection point and fails entirely if that
central device fails?
A. Bus
B. Ring
C. Star
D. Mesh
Correct Answer: C. Star
Rationale:
In a star topology, all devices connect to a central device (e.g., switch). If it fails, the network
goes down.
9. Which topology provides maximum redundancy because every node connects
to every other node?
A. Bus
B. Ring
