Computer Networks Questions & Answers – RIP v2
1. Which statement is true regarding
classless routing protocols?
a) The use of discontinuous networks is not allowed
b) The use of variable length subnet masks is permitted
c) RIPv1 is a classless routing protocol
d) RIPv2 supports classless routing
a) The use of discontinuous networks is not allowed
b) The use of variable length subnet masks is permitted
c) RIPv1 is a classless routing protocol
d) RIPv2 supports classless routing
Answer: b
Explanation: Classful routing means that all hosts in the internetwork use the same mask. Classless routing means that you can use Variable Length Subnet Masks (VLSMs) and can also support discontinuous networking.

2. What is route poisoning?
a) It sends back the protocol received from a router as a poison pill, which stops the regular updates. The use of variable length subnet masks is permitted
b) It is information received from a router that can’t be sent back to the originating router.RIPv2 supports classless routing
c) It prevents regular update messages from reinstating a route that has just come up
d) It describes when a router sets the metric for a downed link to infinity
a) It sends back the protocol received from a router as a poison pill, which stops the regular updates. The use of variable length subnet masks is permitted
b) It is information received from a router that can’t be sent back to the originating router.RIPv2 supports classless routing
c) It prevents regular update messages from reinstating a route that has just come up
d) It describes when a router sets the metric for a downed link to infinity
Answer: d
Explanation: When a network goes down, the distance-vector routing protocol initiates route poisoning by advertising the network with a metric of 16, or unreachable.

3. Which of the following is true
regarding RIPv2?
a) It has a lower administrative distance than RIPv1
b) It converges faster than RIPv1
c) It has the same timers as RIPv1
d) It is harder to configure than RIPv1
a) It has a lower administrative distance than RIPv1
b) It converges faster than RIPv1
c) It has the same timers as RIPv1
d) It is harder to configure than RIPv1
Answer: c
Explanation: RIPv2 is pretty much just like RIPv1. It has the same administrative distance and timers and is configured just like RIPv1.
Explanation: RIPv2 is pretty much just like RIPv1. It has the same administrative distance and timers and is configured just like RIPv1.
4. Which of the situations might not
require require multiple routing protocols in a network?

c) When you are using routers from multiple vendors
d) When there are host-based routers from multiple vendors
a) When a new Layer 2-only switch is added to the network

6. Which is a reason for avoiding
doing route redistribution on two routers between the same two routing domains?
a) Higher cost of two routers
b) Routing feedback
c) Cisco IOS incompatibility
d) Not possible to use two routers
a) Higher cost of two routers
b) Routing feedback
c) Cisco IOS incompatibility
d) Not possible to use two routers
Answer: b
Explanation: Routing feedback is a reason for avoiding doing route redistribution on two routers between the same two routing domains.
Explanation: Routing feedback is a reason for avoiding doing route redistribution on two routers between the same two routing domains.
