NEW QUESTION # 372
A branch office has a primary L3VPN MPLS connection back to the main office and an IPSEC VPN tunnel that serves as backup. Which design ensures that data is sent over the backup connection only if the primary MPLS circuit is down?
Use EIGRP to establish a neighbor relationship with the main office via
Answer: D
NEW QUESTION # 373
An engineer must peer with an ISP for internet connectivity using BGP, initially, the engineer wants to receive only specific prefixes from the ISP and a default route. However, the solution must provide the flexibility to add prefixes in the future at short notice. The ISP has a two-week change process in place.
Which route filtering solution must the engineer employ?
Answer: A
Explanation:
BGP outbound route filtering is the correct solution because the enterprise wants control over which routes it receives without waiting for a provider change cycle each time the prefix set changes. Cisco BGP prefix- based ORF allows a receiving BGP speaker to send an inbound prefix-list filter to the remote peer, which then applies that list as an outbound filter. This reduces unwanted routing updates before they cross the session and lets the enterprise update the desired prefixes locally when business requirements change. Requesting only fixed prefixes from the ISP would work initially but fails the flexibility requirement because the provider has a two-week change process. Requesting a full table and filtering inbound would provide flexibility but wastes memory and CPU on the customer router because all routes are still received before filtering. A maximum- prefix limit does not select the correct routes. ORF is therefore the scalable operational design for receiving a default route and selected prefixes with minimal provider involvement. Reference topics: BGP ORF, prefix- based filtering, inbound route control, ISP peering design, routing table scale.
NEW QUESTION # 374
An engineer must connect a new remote site to an existing OSPF network. The new site consists of two low-end routers, one for WAN, and one for LAN. There is no demand for traffic to pass through this area. Which area type does the engineer choose to provide minimal router resources utilization, while still allowing for full connectivity to the rest of the network?
Answer: D
Explanation:
LSA type1 + type2 + Defaut required to minimise Router resources utilization -> total stub area.
NEW QUESTION # 375
A company ' s security policy requires that all connections between sites be encrypted in a manner that does not require maintenance of permanent tunnels. The sites are connected through a private MPLS-based service that uses a dynamically changing key and spoke-to-spoke communication. Which type of transport encryption must be used in this environment?
Answer: D
Explanation:
GETVPN is the correct transport-encryption design for this environment. The company is using a private MPLS-based service and requires encryption without maintaining permanent point-to-point tunnels. GETVPN was designed for private WAN environments where routing remains native and packets are encrypted without adding GRE or IPsec tunnel overlays between every pair of sites. It uses group-based keying, typically with key servers that distribute security policy and rekey material to group members. That supports dynamic key rotation and spoke-to-spoke communication while avoiding the operational burden of building and maintaining individual tunnels. DMVPN also supports dynamic spoke-to-spoke tunnels, but it is still a tunnel overlay using mGRE, NHRP, and IPsec, and it is usually selected for Internet or mixed transport overlays.
Standard IPsec VPN requires maintaining tunnel relationships, and GRE VPN alone does not provide encryption. GETVPN therefore best matches tunnel-less encryption across a private MPLS WAN with centralized security policy and direct site-to-site forwarding. Reference topics: GETVPN, group encrypted transport, tunnel-less IPsec, private MPLS WAN encryption, group keying.
NEW QUESTION # 376
Which two overlay network design considerations must be made for a Cisco SD-Access network? (Choose two.)
Answer: A,D
Explanation:
The SD-Access overlay should reduce subnet sprawl and avoid overlapping IP subnets unless there is a specific operational requirement. Cisco SD-Access creates overlay virtual networks over an IP underlay and uses anycast gateway, VXLAN encapsulation, LISP control-plane mapping, and policy constructs to simplify endpoint mobility and segmentation. Reducing the number of subnets simplifies DHCP scope management, default-gateway placement, and operational troubleshooting. Avoiding overlapping address space across overlay networks is also a practical design recommendation because overlapping subnets complicate shared services, fusion routing, security logging, and policy troubleshooting. LAN automation and a dedicated IGP process are underlay deployment considerations, not overlay design choices. Layer 3 to the access design is also associated with routed underlay and campus fabric transport, not the overlay segmentation model. A clean overlay design should define virtual networks, scalable groups, IP pools, shared-services reachability, and external connectivity before deployment. Reference topics: Cisco SD-Access overlay design, anycast gateway, virtual networks, DHCP simplification, overlapping subnet avoidance.
