(Choose two.)

• A.There is a mismatch in the poll interval parameter between routers R1 and R2.
• B.There is a mismatch in the hold timer parameter between routers R1 and R2.
• C.There is a mismatch in the dead interval parameter between routers R1 and R2.
• D.There is a mismatch in the hello interval parameter between routers R1 and R2.

You work for a service provider and need to build EVPN service which provides an active/active multihoming topology using a single CE at each site.
In this scenario, which two statements are true? (Choose two.)

• A.A designated forwarder is elected for forwarding BUM traffic to the CE device.
• B.The Ethernet segment identifier must be an all zeros identifier.
• C.A backup designated forwarder is elected for forwarding BUM traffic to the CE device.
• D.An Ethernet segment appears as a LAG to the CE device.

You are working with a new MPLS network that is using the default EXP classifier and default schedules. A small amount of traffic is being placed in the assured forwarding class.
No other traffic is passing through the network at this time.
In this scenario, what happens to the traffic that is being placed in the assured forwarding class?

• A.The traffic remains in the assured forwarding class and is forwarded.
• B.The traffic is reclassified to the best effort forwarding class and is forwarded.
• C.The traffic remains in the assured forwarding class and is dropped.
• D.The traffic is reclassified to the network control forwarding class and is forwarded.

Refer to the exhibit.

Your network engineer reported that they lost BGP connectivity to the neighbor 192.163.6.4 one hour ago, for five to ten minutes.
What are two ways to determine what happened? (Choose two.)

• A.View the information on the BGP monitoring station at 192.168.44.100.
• B.Run the show bgp neighbor orf 192.163.6.4 detail command.
• C.Run the show log bgptrace command and search for the time of the lost connectivity.
• D.Run the show log messages command and search for the time of the lost connectivity.

Each router in the exhibit is receiving three copies of the same IS-IS LSP from the other three routers in the topology. The additional copies of the IS-IS LSPs are causing additional processing overhead on each router. You want to reduce the overhead required to process the additional copies of the same IS-IS LSP.
Which feature accomplishes this task?

• A.Increase the SPF delay.
• B.Lower the CSNP interval.
• C.Configure mesh groups.
• D.Configure traffic engineering.
