CCNA 4 v5 Final Exam answers

CCNA 4 v5 Final Exam answers

1 Why is it useful categorize networks by size when discussing network design?
Knowing the number of connected devices will define how many additional layers will be added to the three-tier hierarchical network design.
Knowing the number of connected devices will define how many multilayer switches will be necessary at the core layer.
A high-level redundancy at the access layer may be better implemented if the number of connected devices is know.
The complexity of networking infrastructure will vary according to the number of connected devices.
2 Which two statements are true regarding a PPP connection between two Cisco routers? (Choose two.)
Only a single NCP is allowed between the two routers.
NCP terminates the link when data exchange is complete.
With CHAP authentication, the routers exchange plain text passwords.
LCP tests the quality of the link.
LCP manages compression on the link.

1. How is “tunneling” accomplished in a VPN?
New headers from one or more VPN protocols encapsulate the original packets.
All packets between two hosts are assigned to a single physical medium to ensure that the packets are kept private.
Packets are disguised to look like other types of traffic so that they will be ignored by potential attackers.
A dedicated circuit is established between the source and destination devices for the duration of the connection.
