Which configuration is used when matching a prefix-list <name> in a route map?

• A.  match ip next-hop mylist
• B.  match ip address prefix-list mylist

Which four statements are correct regarding IS-IS operations? (Choose four.)

• A.  The IS-IS backbone is a contiguous collection of Level 1 capable routers, each of which can be in a different area.
• B.  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.
• C.  Cisco IOS XR Software supports multitopology for IPv6 IS-IS unless single topology is explicitly configured in IPv6 address-family configuration mode.
• D.  Summarization should be configured on the Level 2 routers, which injects the Level 2 routes into Level 1.
• E.  IS-IS supports "route leaking" in which selected Level 2 routes can be advertised by a
  Level 1/Level 2 router into Level 1.
• F.  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.

Which two of the following are true regarding the BGP Prefix-Based outbound route filtering feature? (Choose two.)

• A.  Outbound route filtering is more effective when a distance vector IGP is used.
• B.  Outbound route filtering is configured only on a per-address family basis.
• C.  Outbound route filtering can be configured for either iBGP or eBGP sessions.
• D.  IP multicast routes are not supported.
• E.  The outbound route filter can be defined in a Prefix list, Distribute list or Access lists.

Routers B and C in transit AS 200 are the exit points toward AS 100 and AS 300. Router B is running Cisco IOS XR and Router C IOS XE. Internally, AS 200 runs OPSF only for internal routing. Which two methods can an engineer use to ensure proper reachability between AS 100 and AS 300 for the needed routes? (Choose two.)

• A.  Router C:
  router ospf 200
  redistribute bgp 200 metric-type 1 subnets tag 200
  router bgp 200
  address-family ipv4
  redistribute ospf 200 route-map match-tag match external
  route-map match-tag deny 10
  match tag 200
• B.  Router C:
  router ospf 200
  redistribute bgp 200 metric-type 1 subnets tag 200
  router bgp 200
  address-family ipv4
  redistribute ospf 200
• C.  Router B:
  router ospf 200
  redistribute bgp 200
  router bgp 200
  address-family ipv4 unicast
  redistribute ospf 200
• D.  Router B:
  router ospf 200
  redistribute bgp 200 tag 20
  router bgp 200
  address-family ipv4 unicast
  redistribute ospf 200 metric-type 2
• E.  Router C:
  router ospf 200
  redistribute bgp 200 metric-type 1 subnets tag 200
  router bgp 200
  address-family ipv4
  redistribute ospf 200 match external 2
