What is the possible root cause?
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?
What is preventing the labels from populating the MPLS forwarding table?
Refer to the exhibit.
Routers R1 and R2 have exchanged label binding information. What is preventing the labels from
populating the MPLS forwarding table?
What could be the cause of this problem?
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?
Which feature allows the LDP protocol to be automatically enabled on interfaces that run IGP on the routers?
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?
Which two BGP attributes are used by a route reflector to avoid this issue?
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.)
What should be configured to install that route?
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?
Which two options satisfy this requirement?
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.)
Which BGP attribute can be modified to solve this network reachability issue in this type of scenario?
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?
What is the most likely cause of this issue?
The SP core supports PIM-SM for multicast traffic, but one of these routers is not able to see one
of its PIM neighbors. What is the most likely cause of this issue?
how will R1 handle that traffic?
Refer to the exhibit.
There are receivers that are registered at the RP. If the source begins sending multicast traffic
toward R1, how will R1 handle that traffic?
