Drag and drop the EIGRP query condition on the left to the corresponding action taken by the router on the right.

Correct Answer:

Which two options are mandatory components of a multiprotocol BGP VPN-IPv4 address? (Choose two.)

• A.a route target
• B.an MPLS label
• C.an area ID
• D.an IPv4 address
• E.a system ID
• F.a route distinguisher

Which two statements about STP are true? (Choose two)

• A.MST configurations are propagated throughout the VTP domain
• B.To support load-balancing across redundant paths, the VAN-to-instance mapping must match on all
• C.Rapid PVST+ and MST can be active on a device simultaneously
• D.switches in each path
• E.MST supports up to four MST instances, including instance 0
• F.Only one version of STP can be active on a device at one time

How does having an EIGRP feasible successor speed up convergence?

• A.EIGRP sends queries only if there is not a feasible successor, which causes less control traffic to compete with data.
• B.EIGRP sends queries only if there is a feasible successor, which decreases the number of routers that are involved in convergence.
• C.EIGRP preinstalls the feasible successor in the RIB in all cases, which causes traffic to switch more quickly.
• D.EIGRP immediately installs the loop-free alternative path in the RIB.

What are two conditions that can cause UDLD to move an interface into the errdisable state? (Choose two.)

• A.An ACL denying all IP traffic is applied to a switchport.
• B.A switch receives its own UDLD message on the same port it has sent it from.
• C.A port in normal UDLD mode fails to receive a UDLD message for a prolonged time period.
• D.UDLD detects a mismatch between timer settings on neighboring switches.
• E.The list of detected neighbors in a received UDLD message is missing the receiving switch ID and port ID combination.
