Which command group does a network administrator use to filter out R3 (3.3.3.3 subnet) from the R4 routing tab
Refer to the exhibit.
Which command group does a network administrator use to filter out R3 (3.3.3.3 subnet) from the
R4 routing table?
What is the expected state after running the show ip OSPF neighbor command on the OSPF designated router?
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?
How many type 3 LSAs will be generated by Router 2 into area 0 to advertise all prefixes that are announced by
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?
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.)
