NEW QUESTION 31
An engineer is designing an EIGRP network for a small branch site where there is only one Layer 3 router.
The engineer wants the router to advertise the local LAN network to remote EIGRP neighbors without sending any unnecessary multicast messages on the local LAN. Which action should the engineer take?
- A. Redistribute the local LAN network using the redistribute connected command
- B. Advertise the local LAN using the network command and the passive-interface feature
- C. Advertise the local LAN subnet as a stub network
- D. Use a static default route for this site instead of EIGRP
Answer: B
NEW QUESTION 32
Refer to the exhibit.
EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?
- A. R1 forwards the traffic to R3, but R3 drops the traffic
- B. R1 load-balances across the paths through R3 and R4 to reach R2
- C. R1 forwards the traffic to R3 in order to reach R2
- D. R1 has no route to R2 and drops the traffic
Answer: D
Explanation:
The EIGRP stub routing feature will prevent the remote device from advertising core routes back to the distribution devices. Routes learned by the remote device from Distribution 1 will not be advertised to Distribution 2. Therefore, Distribution 2 will not use the remote device as a transit for traffic destined to the network core https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_eigrp/configuration/15-mt/ire-15-mt-book/ire-eigrp-stub-rtg.html

NEW QUESTION 37
Which design element should an engineer consider when multicast is included in a Cisco SD-Access architecture?
- A. Multicast traffic is transported in the overlay and the EID space for wired and wireless clients.
- B. Rendezvous points must be used in a PIM SSM deployment.
- C. Multicast clients reside in the underlay, and the multicast source is outside the fabric or in the overlay.
- D. PIM SSM must run in the underlay.
Answer: A
Explanation:

NEW QUESTION 44
A network engineer must segregate three interconnected campus networks using IS-IS routing.

- B. Designate two IS-IS routers as BDR routers at the edge of each campus, and configure one BDR for all Level 1 routers and one BDR for all Level 2 routers.
- C. Utilize different MTU values for each campus network segment. Level 2 backbone routers must utilize a larger MTU size of 9216.
- D. Designate two IS-IS routers from each campus to act as Level 1/Level 2 backbone routers at the edge of each campus network.
- E. Assign a unique IS-IS NET value for each campus, and configure internal campus routers with Level 1 routing.
