False. PIM does not have a hop-count limit. DVMRP has a hop-count limit of 32.

False. BGP uses several attributes in the BGP decision process.

RIPv2, OSPF, and EIGRP.

OSPF. Although RIPv2 and EIGRP support VLSMs, RIPv2 is no longer recommended.
EIGRP is not supported on non-Cisco routers.

All traffic from one area must travel through Area 0 (the backbone) to get to another
area.

OSPFv3 is identified as IPv6 Next Header 89.

H. RIPv1 and RIPv2 generate periodic routing traffic. IS-IS is used in SP networks.
BGP is used for external networks.
32.
B. OSPFv3 is used in IPv6 networks.
33.
B. From Router A, the OSPF cost for Path 1 is 108 / 256 kbps = 390. The OSPF cost
for Path 2 is (108 / 1536 kbp s) + (108 / 1024 kbp s) + (108 / 768 kbp s) = 65 + 97 + 130
= 292. OSPF selects Path 2 because it has a lower cost.

Router A = Internal; Router B = ABR; Router C = Backbone; Router D = ASBR; Router
E = ABR; Router F = Internal.

hand, the local preference attribute is exchanged between iBGP peers and is config-
ured at the gateway router.

Route reflectors reduce the number of iBGP logical mesh connections.
