Cisco Designing Cisco Enterprise Networks Sample Questions (Q454-Q459):

NEW QUESTION # 454

Refer to the exhibit. An architect is designing a Layer 3 campus network The design must hide network instability, reduce network overhead, and conserve critical device memory Which route summarization solution must the architect select?

A. * The core layer must advertise a default route toward the aggregation layer
* The VLAN subnets must be summarized into 10 0 0 0. ' 16 at the aggregation layer and advertised to the core layer
B. * The aggregation layer must advertise a default route toward the access layer.
* The VLAN subnets must be summarized into 10 0.0 0/16 at the aggregation layer and advertised to the core layer
C. * The core layer must advertise a default route toward the aggregation layer
* The VLAN subnets must be summarized into 10 0 0 0/16 at the access layer and advertised to the aggregation layer
D. * The aggregation layer must advertise a default route toward the core layer
* The VLAN subnets must be summarized into 10 0 0 0.116 at the aggregation layer and advertised to the access layer

Answer: B

Explanation:
The best summarization design is for the aggregation layer to advertise a default route toward the access layer and to summarize the VLAN subnets toward the core. Cisco hierarchical campus design uses summarization at natural layer boundaries so that access-layer instability is hidden from the rest of the network. If individual access VLANs flap, the core should not have to process every specific route change. Advertising a summary such as 10.0.0.0/16 from the aggregation layer toward the core reduces routing-table size, lowers CPU and memory use, and confines convergence events to the lower layer. At the same time, the access layer normally does not need full knowledge of the enterprise routing table; a default route from the aggregation layer is sufficient for northbound reachability. Summarizing at the access layer is normally less effective because the aggregation layer is the first stable boundary that sees multiple access networks. Advertising a default from the core toward aggregation would hide information in the wrong direction. Reference topics: hierarchical routing, route summarization, campus aggregation design, convergence containment, routing-table scaling.

NEW QUESTION # 455
Which two functions is the Cisco SD-Access Edge Node responsible for? (Choose two.)

A. Map users to virtual network
B. Route and transport IP traffic
C. Act as anycast layer 3 gateway
D. Advertise EID subnets
E. Act as LISP proxy tunnel router

Answer: A,C

Explanation:
The Cisco SD-Access edge node acts as the access-layer fabric device that connects endpoints to the fabric, provides the anycast Layer 3 gateway, and maps users or endpoints into the correct virtual network. Cisco SD- Access fabric edges register endpoint information with the control-plane node and encapsulate user traffic into VXLAN for transport across the fabric. The anycast gateway function allows a consistent default gateway to exist on multiple edge nodes, supporting mobility without forcing traffic through a central gateway. The edge node also applies policy context by associating users, endpoints, or ports with a virtual network and scalable group information. Advertising EID subnets is primarily associated with border connectivity and external route advertisement. LISP proxy tunnel router functionality belongs to border node behavior for external connectivity. Routing and transporting IP packets between fabric nodes is the intermediate-node underlay role. Therefore, the two edge-node functions in the options are acting as the anycast Layer 3 gateway and mapping users to virtual networks. Reference topics: SD-Access edge node, anycast gateway, endpoint registration, virtual networks, fabric policy.
