質問 # 403
Which control plane protocol is responsible for ElD-to-RLOC mapping concerning SO-Access Architecture?
正解：C
解説：
LISP is the control-plane protocol responsible for Endpoint Identifier to Routing Locator mapping in Cisco SD-Access. In the SD-Access architecture, an endpoint address is treated as an EID, and the fabric node location is represented by an RLOC. The fabric control-plane node performs LISP map-server and map- resolver functions so edge nodes can register local endpoints and resolve the current location of remote endpoints. This separation allows the overlay to support host mobility, anycast gateway behavior, and segmentation without depending only on traditional subnet-bound forwarding. VXLAN is the fabric data- plane encapsulation used to carry traffic across the fabric and preserve policy information, but it does not provide the EID-to-RLOC mapping function. CEF is the local forwarding mechanism inside Cisco devices, and GBAC is not the SD-Access mapping protocol. Therefore, LISP is the correct answer because it provides the SD-Access fabric control plane. Reference topics: Cisco SD-Access control plane, LISP, EID, RLOC, map-server, map-resolver.
質問 # 404
An engineer is tasked with designing a dual BGP peering solution with a service provider. The design must meet these conditions:
* The routers will not learn any prefix with a subnet mask greater than /24.
* The routers will determine the routes to include in the routing table based on the length of the mask alone.
* The routers will make this selection regardless of the service provider configuration.
Which solution should the engineer include in the design?
正解：A
解説：
An inbound IP prefix list is the correct tool because the routers must decide which prefixes to accept from the service provider based only on prefix length. Prefix lists are designed to match network prefixes and mask- length ranges using operators such as le and ge. Applying the prefix list inbound to the BGP neighbors prevents routes with masks longer than /24 from entering the local BGP table, regardless of what the service provider advertises. This conserves memory and ensures the customer routing policy is enforced locally. An access list is a poor fit because it does not natively express prefix-length logic as cleanly as a prefix list.
Applying the policy outbound would filter routes the customer sends to the provider, which is the wrong direction; the requirement is about routes the customer learns. A route map could reference a prefix list, but the simplest and most exact answer is to use an IP prefix list inbound. Therefore, the design should apply an inbound prefix list to both BGP peers to block prefixes greater than /24. Reference topics: BGP route filtering, prefix lists, inbound policy, maximum accepted prefix length.
質問 # 405
A network engineer is redesigning a company ' s QoS solution. The company is currently using IP Precedence, but the engineer plans to move to DiffServ. It is important that the new solution provide backward compatibility with the current solution. Which technology should the design include?
正解：A
解説：
Class selector code points provide backward compatibility between IP Precedence and DiffServ. IP Precedence uses the three most significant bits of the former Type of Service field. DiffServ expands QoS marking by using the six-bit DSCP field, but class selector values preserve compatibility by setting the three high-order bits to match the corresponding IP Precedence value while leaving the lower bits as zeros. For example, CS3 corresponds to the old precedence value 3, and CS6 corresponds to precedence 6. This allows devices that still interpret IP Precedence to provide broadly consistent treatment while newer DiffServ-aware devices can use DSCP-based policy. Expedited forwarding is used for low-loss, low-latency traffic such as voice. Assured forwarding provides drop precedence within classes. Default per-hop behavior represents best- effort treatment. None of those are specifically the backward-compatibility mechanism for migration from IP Precedence. Therefore, the design should include class selector code points during the transition to DiffServ.
Reference topics: DiffServ, DSCP, class selector, IP Precedence compatibility, QoS marking migration.
