Which design consideration should be observed when EIGRP is configured on Data Center switches?
A. Perform manual summarization on all Layer 3 interfaces to minimize the size of the routing table.
B. Prevent unnecessary EIGRP neighborships from forming across switch virtual interfaces.
C. Lower EIGRP hello and hold timers to their minimum settings to ensure rapid route
reconvergence.
D. Configure multiple EIGRP autonomous systems to segment Data Center services and applications.

Which design consideration must be made when using IPv6 overlay tunnels?

• A. Overlay tunnels that connect isolated IPv6 networks can be considered a final IPv6 network architecture.
• B. Overlay tunnels should only be considered as a transition technique toward a permanent solution.
• C. Overlay tunnels can be configured only between border devices and require only the IPv6 protocol stack.
• D. Overlay tunneling encapsulates IPv4 packets in IPv6 packets for delivery across an IPv6 infrastructure.

When a network is designed using IS-IS protocol, which two circuit types are supported? (Choose

What is an advantage of designing an out-of-band network management solution?

• A. In the event of a production network outage, network devices can still be managed.
• B. There is no separation between the production network and the management network.
• C. In the event of a production network outage, it can be used as a backup network path.
• D. It is less expensive than an in-band management solution

Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-
Access Architecture?

• A. DHCP-relay must be enabled on fabric edge nodes to provide the correct mapping of DHCP scope to the local anycast gateway.
• B. A DHCP server must be enabled on the border nodes to allow subnets to span multiple fabric edges.
• C. DHCP servers must support Cisco SD-Access extensions to correctly assign IPs to endpoints in an SD-Access fabric with anycast gateway.
• D. DHCP Option-82 must be enabled to map the circuit IP option to the access fabric node where the DHCP discover originated.

• D. DHCP Snooping on layer 2 devices

Which function are fabric intermediate nodes responsible for in an SD-Access Architecture?
