Networking questions part 4

Another batch of random network questions, specifically targeted at the CCNA exam for those budding engineers out there - or people like me that need refreshing sometimes :-) enjoy.


1. What does 'r' stand for in the capabilities of a Cisco device in the output of a show cdp neighbor command?

A) Repeater
B) Router
C) IGMP
D) Host
E) Switch

2. What describes the role of the Session layer?

A) Provides transport services
B) Translates between different data formats
C) Supports communication between applications
D) Establishes and terminates communications between applications

3. What is the default VTP mode of operation for the Cisco Catalyst switch?

A) Client
B) Server
C) Transparent

4. The maximum default hop count for Routing Information Protocol (RIP) is?

A) 1
B) 10
C) 15
D) 16
E) 30

5. What is the purpose of VTP pruning?

A) Reduces unnecessary VLANS
B) Reduces traffic on VLAN1
C) Reduces unnecessary broadcast and multicast traffic
D) A mechanism used to create Switched VLANs
E) Manages the addition, deletion, and renaming of VLANs

1. Correct Answer: A

Explanation: Router#show cdp neighbors 

Capability Codes: 

• R - Router, 
• T - Trans Bridge, 
• B - Source Route Bridge,  
• S - Switch, 
• H - Host, 
• I - IGMP, 
• r - Repeater

2.  Correct Answer: D

Explanation: The Session Layer (layer 5) of the OSI model provides the mechanism for opening, closing and managing a session between end-user application processes.

3. Correct Answer: B

Explanation: The default mode for all Catalyst switches is Server.
A VTP domain requires at least one VTP server.

4. Correct Answer: C

Explanation: The maximum allowable hop count for RIP is 15 by default. 16 is unreachable.

5.  Correct Answer: C

Explanation: VTP pruning makes more efficient use of VLAN trunk bandwidth by reducing unnecessary broadcast traffic. Broadcast and unknown uni-cast frames on a VLAN are only forwarded over a trunk link if the switch on the receiving end of the trunk has ports in that VLAN.
