Section 8 – RIP, EIGRP, OSPF, and BGP

QUESTION 21
With which of the following capabilities does RIPv2 improve RIPv1?
A.    Multicast updates, authentication, variable-length subnet mask (VLSM)
B.    Authentication, VLSM, hop count
C.    Multicast updates, authentication, hop count
D.    Multicast updates, hop count
Answer: A
Explanation:
RIPv2 improves on RIPv1 with the ability to use VLSM, with support for route authentication, and with multicasting of route updates. RIPv2 supports CIDR. It still sends updates every 30 seconds and retains the 15-hop limit; it also uses triggered updates. RIPv2 still uses UDP port 520; the RIP process is responsible for checking the version number. It retains the loop-prevention strategies of poison reverse and counting to infinity. On Cisco routers, RIPv2 has the same administrative distance as RIPv1, which is 120. Finally, RIPv2 uses the IP address 224.0.0.9 when multicasting route updates to other RIP routers. As in RIPv1, RIPv2 by default summarizes IP networks at network boundaries. You can disable auto summarization if required.

QUESTION 22
For the following protocols, which one maps names to IPv6 addresses?
A.    Domain Name System (DNS)
B.    DNSv2
C.    Address Resolution Protocol (ARP)
D.    Neighbor discovery (ND)
Answer: A

QUESTION 23
In a network with Enhanced Interior Gateway Routing Protocol (EIGRP) and IGRP using the same autonomous system number, what will happen on the router configured with both protocols?
A.    Redistribution occurs automatically.
B.    Redistribution is not necessary.
C.    EIGRP assumes IGRP is a less capable protocol and overtakes it.
D.    Redistribution does not occur automatically.
Answer: A

QUESTION 24
Which two of these are the most accurate characteristics of EIGRP deployment? (Choose two.)
A.    Provides features for most Ethernet, Frame Relay, and dial-up network deployment types.
B.    Provides routing for IPv4, IPv6, Appletalk, and IPX.
C.    Provides default hierarchical routing and summarization of a VLSM IP address deployment.
D.    Provides quick convergence through neighbor relationships and topology backup routes.
E.    Provides the best route selection on combined default metrics of active bandwidth, delay, load, reliability, and MTU parameters.
Answer: BD
