NEW QUESTION # 285
Which two LISP components are required in the Cisco SD-Access fabric control plane node? (Choose two.)
Answer: A,E
Explanation:
The Cisco SD-Access fabric control-plane node requires the LISP Map-Resolver and Map-Server functions.
In SD-Access, fabric edge nodes register locally attached endpoints with the control-plane node, and other fabric nodes query the control plane when they need to locate a destination endpoint. The Map-Server stores Endpoint Identifier to Routing Locator bindings, while the Map-Resolver resolves lookup requests and returns mapping information so the source edge node can encapsulate traffic toward the correct remote fabric node.
Ingress Tunnel Router and Egress Tunnel Router roles are performed by fabric edge or border nodes that encapsulate and decapsulate user traffic, not by the dedicated control-plane function. The option labeled Map- Server Proxy reflects the map-server role used in the answer set, while the Map-Resolver is explicitly required. This separation lets SD-Access provide host mobility, anycast gateway behavior, and scalable endpoint reachability without flooding. Reference topics: Cisco SD-Access control plane, LISP, Map-Server, Map-Resolver, EID-to-RLOC mapping, fabric edge registration.
NEW QUESTION # 286 
Refer to the exhibit An engineer is designing a hierarchical ISIS solution for an enterprise customer with these requirements
* Users in areas 25 and 55 send and receive traffic from both backbone areas
* Link flaps in areas 35 and 45 must not impact other areas
* Routers will double within the next 12 months in areas 35 and 45
Which design must the engineer select?
Answer: A
Explanation:
The IS-IS hierarchy should place access or internal area routers at Level 1, boundary routers at Level 1/2, and backbone routers at Level 2. In this exhibit, users in areas 25 and 55 must send and receive traffic through both backbone areas, while link flaps in areas 35 and 45 must not affect other areas. Cisco IS-IS design uses Level 1 areas to contain local topology changes and Level 2 routing to interconnect areas through the backbone. Level 1/2 routers sit at the area boundary and leak or advertise reachability between the local Level
1 area and the Level 2 backbone. Option C matches that hierarchy by placing A-series routers as Level 1, B- series routers as Level 1/2, and C-series routers as Level 2. Making too many routers Level 1/2 would expand the impact of topology changes and reduce scaling benefits. Making backbone routers Level 1 would break interarea design. Reference topics: IS-IS hierarchy, Level 1, Level 2, Level 1/2 routers, failure-domain containment, enterprise scaling.
NEW QUESTION # 287
An infrastructure team is concerned about the shared memory utilization of a device, and for this reason, they need to monitor the device state. Which solution limits impact on the device and provides the required data?
Answer: D
NEW QUESTION # 288
Refer to the exhibit. A company specializing in VoD content creation has two offices in a separate multicast domain connected by a WAN link. BGP communication has been established between the offices. Clients are inside the LAN in each office. In AS5373, R2 has been selected as RP.
What must the network architect design to deliver VoD content to clients in AS65773?
Answer: C
NEW QUESTION # 289
A company with multiple service providers wants to speed up BGP convergence time in the event a failure occurs with their primary link.
Which approach achieves this goal and does not impact router CPU utilization?
Answer: C
Explanation:
The issue is to speed up BGP convergence time in the event a FAILURE occurs and keep the CPU utilisation low - then BFD is the solution.
