NO.2 Refer to the PE1 router routing table output exhibit.
What is causing the i su 10.1.10.0/24 [115/30] via 0.0.0.0, 00:40:34, Null0 entry on the PE1 router routing
table?
A. The PE1 router is receiving the 10.1.10.0/24 summary route from the upstream L1/L2 IS-IS router.
B. The PE1 router has been configured to summarize the 10.1.10.x/32 IS-IS routes to 10.1.10.0/24.
C. The 10.1.10.0/24 has been suppressed because IS-IS auto-summary has been disabled on the PE1
router.
D. The 10.1.10.0/24 has been suppressed because of a route policy configuration on the PE1 router.
E. The 10.1.10.0/24 has been suppressed because the more specific 10.1.10.x/32 IS-IS routes have
been configured to leak into the IS-IS non-backbone area.
Answer: B

NO.3 Which four statements are correct regarding IS-IS operations? (Choose four.)
A. By default, Level 1 routers within an IS-IS area do not carry any routing information external to the area
to which they belong. They use a default route to exit the area.
B. Summarization should be configured on the Level 2 routers, which injects the Level 2 routes into Level
1.
C. IS-IS supports "route leaking" in which selected Level 2 routes can be advertised by a Level 1/Level 2
router into Level 1.
D. The IS-IS backbone is a contiguous collection of Level 1 capable routers, each of which can be in a
different area.
E. With IS-IS, an individual router is in only one area, and the border between areas is on the link that
connects two routers that are in different areas.
F. Cisco IOS XR Software supports multitopology for IPv6 IS-IS unless single topology is explicitly
configured in IPv6 address-family configuration mode.
Answer: A,C,E,F

other methods.

ID goes down. The router ID changes only if the router reloads or if the OSPF routing process restarts.
E. In OSPF version 3, the OSPF router ID uses a 128-bit number.
Answer: A,B,D
