In an OSPF domain, four routers have OSPF neighborship over a broadcast domain. What is the
expected state after running the show ip OSPF neighbor command on the OSPF designated
router?

Refer to the exhibit.

Router 2 connects OSPF area 1 and area 0. Router 2 receives LSA type 1 from Router 1 in area
1. How many type 3 LSAs will be generated by Router 2 into area 0 to advertise all prefixes that
are announced by the Router 1 LSA type 1 packet?

Two OSPF neighbor routers are stuck in the EXSTART state. After a while, the neighborship goes
down. A network engineer is debugging the issue when both routers show the OSPF log message
“too many retransmissions.” What is the possible root cause?

Refer to the exhibit.

Routers R1 and R2 have exchanged label binding information. What is preventing the labels from
populating the MPLS forwarding table?

A router is able to assign labels to the prefixes and MPLS is enabled on all of the router interfaces.
However, this router is unable to establish an LDP session with its LDP neighbors. What could be
the cause of this problem?

A network engineer is responsible for provisioning LDP and IGP over the IP core network to
maintain the MPLS functionality as a day-to-day task. The IP engineer is looking for automation
opportunities. Which feature allows the LDP protocol to be automatically enabled on interfaces
that run IGP on the routers?

A network engineer wants to avoid route looping in an internal BGP. Which two BGP attributes are
used by a route reflector to avoid this issue? (Choose two.)

Refer to the exhibit.

R3 is not able to install the R1 loopback address into its BGP routing table. What should be
configured to install that route?

Refer to the exhibit.

ISP-X customers must be able to reach both ISP-Y and ISP-Z, but ISP-X must not allow transit
traffic between ISP-Y and ISP-Z at any time. Which two options satisfy this requirement? (Choose
two.)

A network engineer is having trouble overcoming a BGP rule: “an EBGP neighbor address
information is carried in the IBGP advertisement. This information does not change to the local
ASBR address”. Which BGP attribute can be modified to solve this network reachability issue in
this type of scenario?
