RIP Questions Flashcards
Question 1
What are two characteristics of RIPv2? (Choose two)
A.classful routing protocol
B. variable-length subnet masks
C. broadcast addressing
D. manual route summarization
E. uses SPF algorithm to compute path
Answer: B D
Question 2
Router_1# show ip protocols
Routing Protocol is “rip”
Sending updates every 30 seconds, next due in 8 seconds
Invalid after 180 seconds, hold down 180, flushed after 240
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
After a RIP route is marked invalid on Router_1, how much time will elapse before that route is removed from the routing table?
A. 30 seconds
B. 60 seconds
C. 90 seconds
D. 180 seconds
E. 240 seconds
Answer: B
Explanation
The invalid and flush timers start at the same time and run concurrently. So after a RIP route is marked invalid, it will take 240 – 180 = 60 seconds for that route to be removed from the routing table.
Question 3
Which three statements are correct about RIP version 2? (Choose three)
A. It has the same maximum hop count as version 1.
B. It uses broadcasts for its routing updates.
C. It is a classless routing protocol.
D. It has a lower default administrative distance than RIP version 1.
E. It supports authentication.
F. It does not send the subnet mask in updates.
Answer: A C E
Question 4
RIP_ISDN.jpg
HQ(config)# router rip
HQ(config-router)# network 172.16.0.0
HQ(config-router)# exit
HQ(con£ig)# ip route 172.16.15.0 255.255.255.0 172.16.18.2 150
Assuming that the routing protocol for the entire network is RIP, and the RIP is configured with its default settings. You properly configure all links and all these links are functioning normally.
Regarding the network described which of the following statements are true? (Choose two)
A. The HQ router will prefer to use its S0 interface to reach E1 of the Branch router.
B. The HQ will prefer to use its BRIO interface to reach E1 on the Branch router.
C. The HQ BRI0 interface will be used to reach the Branch E1 network in the event the S0 link fails.
D. The HQ S0 interface will be used to reach the Branch E1 network in the event the BRI0 link fails.
Answer: A C
Explanation
The HQ router is configured with both static and RIP to reach 172.16.15.0/24 network so it has to use the Administrative Distance of each route to decide which route should it forward the packet to. The static route “ip route 172.16.15.0 255.255.255.0 172.16.18.2 150” is configured with an AD of 150 but the default AD of RIP route is 120 so the RIP path will be favored over static route.
Question 5
Which statement about RIPng is true?
A. RIPng allows for routes with up to 30 hops.
B. RIPng is enabled on each interface separately.
C. RIPng uses broadcasts to exchange routes.
D. There can be only one RIPng process per router.
Answer: B
Explanation
The Routing Information Protocol next generation (RIPng) is an interior gateway protocol (IGP) that uses a distance-vector algorithm to determine the best route to a destination, using the hop count as the metric. RIPng is a routing protocol that exchanges routing information used to compute routes and is intended for Internet Protocol version 6 (IPv6)-based networks.
RIPng is enabled on each interface separately. Below is an example:
R1(config)#ipv6 router rip 9tut //name the process RIPng 9tut
R1(config-rtr)#exit
R1(config)#interface E0/0
R1(config-if)#ipv6 rip 9tut enable //run RIPng 9tut process on E0/0
Question 6
A medium-sized company has a Class C IP address. It has two Cisco routers and one non-Cisco router.
All three routers are using RIP version 1.
The company network is using the block of 198.133.219.0/24.
The company has decided it would be a good idea to split the network into three smaller subnets and create the option of conserving addresses with VLSM.
What is the best course of action if the company wants to have 40 hosts in each of the three subnets?
A. Convert all the routers to EIGRP and use 198.133.219.32/27,198.133.219.64/27, and 198.133.219.92/27 as the new subnetworks.
B. Maintain the use of RIP version 1 and use 198.133.219.32/27,198.133.219.64/27, and 198.133.219.92/27 as the new subnetworks.
C. Convert all the routers to EIGRP and use 198.133.219.64/26,198.133.219.128/26, and 198.133.219.192/26 as the new subnetworks.
D. Convert all the routers to RIP version 2 and use 198.133.219.64/26,198.133.219.128/26, and 198.133.219.192/26 as the new subnetworks.
E. Convert all the routers to OSPF and use 198.133.219.16/28,198.133.219.32/28, and 198.133.219.48/28 as the new subnetworks.
F. Convert all the routers to static routes and use 198.133.219.16/28,198.133.219.32/28, and 198.133.219.48/28 as the new subnetworks.
Answer: D
Question 7
The network shown in the exhibit is running the RIPv2 routing protocol. The network has converged, and the routers in this network are functioning properly.
The FastEthernet0/0 interface on R1 goes down. In which two ways will the routers in this network respond to this change? (Choose two)
A. All routers will reference their topology database to determine if any backup routes to the 192.168.1.0 network are known.
B. Routers R2 and R3 mark the route as inaccessible and will not accept any further routing updates from R1 until their hold-down timers expire.
C. Because of the split-horizon rule, router R2 will be prevented from sending erroneous information to R1 about connectivity to the 192 168.1.0 network.
D. When router R2 learns from R1 that the link to the 192.168.1.0 network has been lost, R2 will respond by sending a route back to R1 with an infinite metric to the 192.168.1.0 network.
E. R1 will send LSAs to R2 and R3 informing them of this change, and then all routers will send periodic updates at an increased rate until the network again converges.
Answer: C D
Question 8
What is the default routing update period for RIPv2?
A. 15 seconds
B. 30 Seconds
C. 180 Seconds
D. 240 Seconds
Answer: B
Question 9
What two things will a router do when running a distance vector routing protocol? (Choose two)
A. Send periodic updates regardless of topology changes.
B. Send entire routing table to all routers in the routing domain.
C. Use the shortest-path algorithm to the determine best path.
D. Update the routing table based on updates from their neighbors.
E. Maintain the topology of the entire network in its database.
Answer: A D
