Refer to the topology diagram in the exhibit.

Which IS-IS feature could be implemented so that the return path for the packets from router Y in
area 49.00AA to router X in area 49.00BB will use the more optimal path?

Refer to the exhibit.

Which two configuration options can be used to optimize the IS-IS network scenario? (Choose
two.)

The Cisco IOS XE Software summary-address router IS-IS configuration command can be used to
send a summarized route into which IS-IS hierarchy?

Refer to the Cisco IOS XE IS-IS configuration exhibit.

What are two problems with the configuration that are causing the IPv4, or the IPv6, or the IPv4
and IPv6 IS-IS operations to fail? (Choose two.)

In which network environment is IS-IS adjacency check important?

Refer to the IS-IS configuration exhibit.

This is the typical IS-IS configuration of the routers in an AS using IS-IS as the IGP. This AS is in
the transition phase of integrating IPv6 into the network. During this transition phase, some of the
routers within the AS might be running IPv4 only, some might be running IPv6 only, and others
might be running both IPv4 and IPv6. To avoid any black holes for the IPv6 traffic, which
configuration change can be made?

When implementing OSPF, which type of networks require DR/BDR election?

The S bit in the MPLS header is used for what purpose?

What are two purposes of the BGP scan-time command? (Choose two.)

When using the show bgp ipv6 unicast summary command to verify the IPv6 BGP session status
with the IPv6 BGP peers, you noticed the “St/PfxRcd” status for one of the IPv6 BGP peers is in
the “Active” state. What does the “Active” state indicate?
