D. OSPFv3 is the only correct answer. RIPv2 is for IPv4 networks. EIGRP is not stan-
dards based. BGPv6 and RIPv3 do not exist.
23.
B, C, and E
24.
B and C. IGPs converge faster than EGPs.
25.
C. Faster routing convergence means more accurate information.
26.
A. Classless network have less routing overhead.
27.
B and C. EIGRP uses DUAL for fast convergence and supports VLSMs.
28.
i = D, ii = B, iii = A, iv = C
29.
C. To reduce broadcast traffic, use EIGRP for IPv4 as the routing protocol for the net-
work. RIPng and EIGRPv6 are for IPv6 networks.
30.
i = B, ii = D, iii = A, iv = C
31.
i = C, ii = A, iii = D, iv = B
32.
B. EIGRP route has a lower administrative distance.
33.
C. EIGRP provides fast convergence and unequal load balancing.
34.
B and C
35.
A is EIGRP for IPv6, B is OSPFv2, C is RIPv2, D is EIGRP for IPv4, E is OSPFv3.
36.
A. The minimum bandwidth via Route 1 is 384 kb/s. The minimum bandwidth via
Route 2 is 128 kbps. The route with the higher minimum bandwidth is preferred, so
the router chooses Route 1.
37.
B. Route 2 has fewer router hops than Route 1.
38.
A. Route 2 has a higher cost than Route 1. The Route 2 cost is 108/128 kbps = 781.25.
The Route 1 cost is 108/512 kbps + 108/384 kbps + 108/512 kbps = 195.31 + 260.41
+ 195.31 = 651.03. Route 1 is preferred.
39.
A. Path 1 has a lower hop count metric.
40.
A. Path 1 has a lower hop count metric.
41.
B. Path 2 has greater bandwidth.
42.
C. Load sharing is enabled with the
variance
command.
43.
B. By default, path 2 has higher bandwidth thus has the better metric.

1.
B. OSPF defines ABRs that connect areas to the OSPF backbone.
2.
G. EIGRP, OSPF, and IS-IS support VLSMs.
