Question #1 (Topic: demo questions)

Which purpose of a dynamically created tunnel interface on the design of IPv6 multicast services Is true?

first-hop router registration to the RP

multicast client registration to the RP

multicast source registration to the RP D. transport of all IPv6 multicast traffic

transport of all IPv6 multicast traffic

Correct Answer: A

Question #2 (Topic: demo questions)

A multicast network is sing Bidirectional PIM. Which two combined actions achieve high availability so that two RPs within the same network can act in a redundant manner? (Choose two)

Use two phantom RP addresses

Manipulate the administration distance of the unicast routes to the two RPs

Manipulate the multicast routing table by creating static mroutes to the two RPs

Advertise the two RP addresses in the routing protocol

Use anycast RP based on MSDP peering between the two RPs

Control routing to the two RPs through a longest match prefix

Correct Answer: A, F

Question #3 (Topic: demo questions)

You want to mitigate failures that are caused by STP loops that occur before UDLD detects the failure or that are caused by a device that is no longer sending BPDUs. Which mechanism do you use along with UDLD?

Root guard

BPDU guard

Loop guard

BPDU filtering

Correct Answer: C

Question #4 (Topic: demo questions)

An enterprise network has two core routers that connect to 200 distribution routers and uses full mesh IBGP peering between these routers as its routing method. The distribution routers are experiencing high CPU utilization due to the BGP process. Which design solution is the most cost effective?

An enterprise network has two core routers that connect to 200 distribution routers and uses full mesh IBGP peering between these routers as its routing method. The distribution routers are experiencing high CPU utilization due to the BGP process. Which design solution is the most cost effective?

Implement route reflectors on the two core routers

Increase the memory on the core routers

Implement e BGP between the core and distribution routers

Increase the memory on the distribution routers

Increase bandwidth between the core routers

Correct Answer: A
