NEW QUESTION # 324
Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?
Answer: A
Explanation:
In a Cisco SD-Access fabric, DHCP relay design must account for the fact that endpoints can attach to different fabric edge nodes while using consistent anycast gateway behavior. DHCP Option 82 is important because it inserts relay-agent information that allows the DHCP infrastructure to identify where the DHCP request originated. This enables the correct address scope and policy context to be selected for the endpoint even when the gateway address is anycast across multiple fabric edges. Cisco SD-Access DHCP guidance emphasizes the use of relay information so centralized DHCP services can assign the correct address based on fabric location and endpoint context. DHCP relay is not simply enabled on border nodes, and subnets should not be stretched across fabric edges by placing DHCP servers on borders. DHCP servers do not require a special proprietary SD-Access extension in the sense described by the incorrect option; they use standard relay information such as Option 82. Therefore, the key design consideration is enabling DHCP Option 82 so the circuit information maps the request to the fabric node where it originated.

An ISP provides Layer 3 VPN service over MPLS to a customer with four branches and multiple CE routers at each branch. To exchange the routes that are learned from the CE routers, which BGP address family should the ISP activate among the PE routers?
Answer: A
Explanation:
The provider must activate the VPNv4 unicast address family between PE routers. In an MPLS Layer 3 VPN, customer routes learned from CE routers are placed into VRFs on the PE routers. To carry those customer routes across the provider backbone without overlap, MP-BGP advertises VPNv4 routes, which combine an IPv4 prefix with a route distinguisher. Route targets then control which receiving VRFs import the routes.
Plain IPv4 unicast would not preserve customer VPN context and would not solve overlapping route separation. L2VPN EVPN is used for Ethernet VPN services and data center or Layer 2 VPN use cases, not classic MPLS L3VPN route exchange between PEs. Address-family multicast is unrelated to exchanging customer unicast routes between PE routers. Cisco MPLS VPN design relies on MP-BGP VPNv4 between provider edge routers, while PE-CE routing can be static, OSPF, EIGRP, BGP, or another supported method.
Therefore, VPNv4 unicast is the correct PE-to-PE address family. Reference topics: MPLS Layer 3 VPN, MP- BGP, VPNv4 unicast, route distinguishers, route targets, PE-CE routing.
NEW QUESTION # 326
Which command is needed to enable DHCP snooping if a switchport is connected to a DHCP server?
Answer: C
Explanation:
When configuring DHCP snooping, follow these guidelines:
DHCP snooping is not active until you enable the feature on at least one VLAN, and enable DHCP globally on the switch.
Before globally enabling DHCP snooping on the switch, make sure that the devices acting as the DHCP server and the DHCP relay agent are configured and enabled.
If a Layer 2 LAN port is connected to a DHCP server, configure the port as trusted by entering the "ip dhcp snooping trust" interface configuration command.
If a Layer 2 LAN port is connected to a DHCP client, configure the port as untrusted by entering the no ip dhcp snooping trust interface configuration command.
