NEW QUESTION # 58
Refer to the exhibit.
Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)
- A. a new OSPF area for R3 and R4 connections, with R5 and R6 as ABRs
- B. a new OSPF area for R1 and R2 connections, with R5 and R6 as ABRs
- C. a new OSPF area for R1, R2, R3, and R4 connections, with R1, R2, R3, and R4 as ABRs
- D. a new OSPF area for R3 and R4 connections, with R3 and R4 as ABRs
- E. a new OSPF area for R1 and R2 connections, with R1 and R2 as ABRs

NEW QUESTION # 60
An engineer must design a multicast network for a financial application. Most of the multicast sources also receive multicast traffic (many-to-many deployment model). To better scale routing tables, the design must not use source trees. Which multicast protocol satisfies these requirements?
- A. PIM-SM
- B. BIDIR-PIM
- C. MSDP
- D. PIM-SSM
Answer: B
Explanation:
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipmulti_pim/configuration/xe-16/imc-pim-xe-16-book/imc-tech-oview.html Bidir-PIM is designed to be used for many-to-many applications within individual PIM domains. Multicast groups in bidirectional PIM mode can scale to an arbitrary number of sources without incurring overhead due to the number of sources.
NEW QUESTION # 61
A network solution is being designed for a company that connects to multiple Internet service providers. Which Cisco proprietary BGP path attribute will influence outbound traffic flow?
- A. Community
- B. Weight
- C. Local Preference
- D. AS Path
- E. MED
Answer: B
NEW QUESTION # 62
Which design element should an engineer consider when multicast is included in a Cisco SD-Access architecture?
- A. Multicast clients reside in the underlay, and the multicast source is outside the fabric or in the overlay.
- B. PIM SSM must run in the underlay.
- C. Rendezvous points must be used in a PIM SSM deployment.
- D. Multicast traffic is transported in the overlay and the EID space for wired and wireless clients.
Answer: D
Explanation:
Explanation
Multicast traffic is transported in the overlay, in the EID space, for both wired and wireless clientshttps://www.ciscolive.com/c/dam/r/ciscolive/us/docs/2018/pdf/BRKEWN-2020.pdf

NEW QUESTION # 65
A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?
- A. Updates that contain changes within the data are sent only when changes occur.
- B. Empty data subscriptions do not generate empty update notifications.
- C. The primary push update is sent immediately and cannot be delayed.
- D. Periodic updates include a full copy of the data that is subscribed to.
Answer: D
Explanation:
Explanation
Periodic updates contain a full copy of the subscribed data element or table for all supported transport protocols

NEW QUESTION # 66
An engineer is designing a BGP network for a large customer. To permit efficient scaling, the BGP domain is split into clusters. Which peering solution should be used between the route reflectors in different clusters for the BGP routes to be propagated appropriately?
- A. The route reflectors should have peering through another nonclient router.
- B. The route reflectors should be nonclients with regards to each other.
- C. The route reflectors should not have any kind of BGP peering.
- D. The route reflectors should be made dents of each other.
Answer: B
Explanation:
When configure multi-cluster of BGP RRs, RRs should peer with each RR as non-client according to CCIE routing TCP/IP volumn 2 @2001 page 127
- if the route was learned from nonclient IBGP peer, it is reflected to client only (here RR's route learnt from other RRs is able to reflect to its client)
- if the route was learned from a client, it is reflected to all nonclients and clients, except for the originating client. (routes learnt within the cluster can reflect to nonclient, RR)
- it the route was learnt from an EBGP peer, it is reflected to all nonclients and clients.
