Which two statements about the IS-IS routing protocol are true? (Choose
two.)
A. In the IS-IS routing domain, routers may have adjacencies with other routers on multipoint links.
B. IS-IS metrics are based on delay, bandwidth, reliability, load, and MTU.
C. Level 1 routers learn about paths within the areas that the routers are connected to.
D. Level 2 routers are equivalent to ABRs in OSPF and learn about paths both within and between areas.
E. Level 1 and Level 2 routing is a function of ES-IS.

In an IS-IS environment, what happens when the designated IS router
crashes?
A. The elected backup designated router takes the place of the DIS indefinitely without the necessity of a new
election.
B. The elected backup designated router takes the place of the DIS temporarily without the necessity of a new
election, until the original DIS comes back online.
C. A new election process occurs immediately, establishing a new DIS that will remain in place indefinitely.
D. A new election process occurs immediately, establishing a new DIS until a router with a higher priority or
MAC address establishes an adjacency.

Which three route filtering statements are true? (Choose three.)
A. After the router rip and passive-interface s0/0 commands have been issued, the s0/0 interface will not send
any RIP updates, but will receive routing updates on that interface.
B. After the router eigrp 10 and passive-interface s0/0 commands have been issued, the s0/0 interface will not
send any EIGRP updates, but will receive routing updates on that interface.
C. After the router ospf 10 and passive-interface s0/0 commands have been issued , the s0/0 interface will not
