More Random Cisco Based networking Questions for you to ponder.
1, In a local broadcast all bits set to 1 received by all hosts on local and remote broadcast domains?
2. Which protocol is used to determine the IP address if the MAC address is already known?
3. What is the invalid timer set to by default when you have a router running the Interior Gateway Routing Protocol?
A) 3 times the update period
B) 270 seconds
C) 3 times the update period + 10 seconds
D) Answer A and B
E) 7 times the update period
4. The startup-config (Cisco) is found in the ...
5. What component of a router holds the routing tables and the software that allows the router to function?
C) ROM monitor
E) Configuration register
6. Which switching mode has the highest degree of error checking?
1. Correct Answer: B
Routers don't forward broadcasts so local broadcasts will stay on the broadcast domain from which they originated.
2. Correct Answer: B
Reverse Address Resolution Protocol (RARP) is a networking protocol used by a host computer to request its IP address from an administrative host, when it knows its MAC address.
3. Correct Answer: D
IGRP sends its routing table to its neighbors every 90 seconds. IGRP uses an invalid timer to mark a route as invalid after 270 seconds (three times the update timer). IGRP uses a flush timer to remove a route from the routing table (default flush timer is 630 seconds, seven times the update period).
4. Correct Answer: C
The startup configuration is stored in NVRAM
5. Correct Answer: D
The running-config is stored in RAM and allows the router to function.
6. Correct Answer: D
Store and forward switching method is known as store and forward because the switch will store the incoming data frame in its internal buffer, then when the complete frame has been received the switch will then run a Cyclic Redundancy Check (CRC) against the frame. If the CRC passes, the switch will then look up the destination MAC Address in its MAC filter table to forward it on to its destination.
