NEW QUESTION # 114
Refer to the exhibit.
Refer to the exhibit. Where must an architect plan for route summarization for the topology?
- A. from the core toward the aggregation and the access toward the aggregation
- B. from the aggregation toward the access and the access toward the aggregation

NEW QUESTION # 115 
Refer to the exhibit. The distribution switches serve as the layer 3 boundary. HSRP preemption is enabled.

Answer: C
NEW QUESTION # 116
How do endpoints inside an SD-Access network reach resources outside the fabric?
- A. A fabric edge is used to de-encapsulate VXLAN traffic to normal IP traffic then transported over the outside network
- B. a VRF fusion router is used to map resources in one VN to another VN
- C. Fabric borders use VRFs to map VNs to VRFs
- D. SD-Access transit links are used to transport encapsulated traffic from one fabric to another
Answer: C
Explanation:

"Packets and frames sourced from inside the fabric and destined outside of the fabric are de-encapsulated by the border node"(not the edge node)

NEW QUESTION # 118
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. Use a static default route for this site instead of EIGRP
- B. Advertise the local LAN using the network command and the passive-interface feature
- C. Redistribute the local LAN network using the redistribute connected command
- D. Advertise the local LAN subnet as a stub network
Answer: B
NEW QUESTION # 119

NEW QUESTION # 120
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 made dents of each other.
- C. The route reflectors should be nonclients with regards to each other.
- D. The route reflectors should not have any kind of BGP peering.
Answer: C
Explanation:
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.
NEW QUESTION # 121
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. AS Path
- B. Community
- C. MED
- D. Local Preference
- E. Weight
Answer: E

NEW QUESTION # 122
Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?
- A. DHCP servers must support Cisco SD-Access extensions to correctly assign IPs to endpoints in an SD-Access fabric with anycast gateway.
- B. DHCP Option-82 must be enabled to map the circuit IP option to the access fabric node where the DHCP discover originated.
- C. DHCP-relay must be enabled on fabric edge nodes to provide the correct mapping of DHCP scope to the local anycast gateway.
- D. A DHCP server must be enabled on the border nodes to allow subnets to span multiple fabric edges.
Answer: B

NEW QUESTION # 125
What are two benefits of designing an SD-WAN network fabric with direct Internet access implemented at every site? (Choose two.)
- A. It alleviates network traffic on MPLS circuits.
- B. It increases the total available bandwidth on Internet circuits.
- C. It decreases latency on Internet circuits.
- D. It decreases latency to applications hosted by public cloud service provider.
- E. It increases the speed of delivery of site deployments through zero-touch provisioning.
Answer: A,D
NEW QUESTION # 126
Which function do reverse path forwarding mechanisms perform in a multicast deployment?
- A. They notify the upstream routerof multicast traffic.
- B. They eliminate overlapping multicast addresses
- C. They send PIM prune message toward multicast sources.
- D. They prevent loops and duplicate packets.
Answer: D
Explanation:
Explanation
Reverse path forwarding (RPF) mechanisms are used to prevent loops and duplicate packets in multicast deployments [1]. The RPF check verifies that all multicast traffic received on a router is sourced from the expected direction, ensuring that multicast traffic is not looped back in the network. The RPF check works by comparing the source IP address of a multicast packet with the routing table, and only forwarding it if it matches the expected entry.
