NEW QUESTION # 59
Which two routing protocols allow for unequal cost load balancing? (Choose two.)
Answer: A,D
Explanation:
EIGRP and BGP are the two listed routing protocols that can support unequal-cost load balancing in Cisco enterprise designs. EIGRP performs unequal-cost load sharing by using the variance command. Feasible successor routes whose feasible distance falls within the variance multiplier can be installed alongside the successor route, provided they satisfy EIGRP loop-prevention rules. This allows traffic to use links with different composite metrics while still maintaining loop-free forwarding. BGP can also support unequal-cost distribution in specific designs, such as using BGP multipath features with additional bandwidth-based mechanisms or policy to influence traffic sharing across nonidentical paths. OSPF and IS-IS commonly support equal-cost multipath, but they do not natively perform EIGRP-style unequal-cost load balancing based on different path metrics. RIPng is also limited by hop-count behavior and is not used for unequal-cost multipath in this context. The correct design answer is therefore EIGRP and BGP. In production, the engineer must still validate hardware forwarding behavior, policy consistency, and whether the traffic-sharing method is per-flow or per-prefix.
NEW QUESTION # 60
An engineer must propose a solution for a campus network that includes the capability to create multiple Layer 3 virtual networks. Each network must have its own addressing structure and routing table for data forwarding. The solution must be scalable to support hundreds of virtual networks and allow simple configuration and management with minimal administrative overhead. Which solution does the engineer recommend?
Answer: A
Explanation:
Easy Virtual Network is the best fit when a campus needs many Layer 3 virtual networks with separate addressing and routing tables but wants lower operational overhead than manually configuring VRF-Lite everywhere. EVN builds on VRF concepts and simplifies virtualization across a hop-by-hop campus design by reducing repetitive configuration and enabling consistent virtual network transport across participating devices. Each virtual network maintains its own routing context, which supports overlapping addressing and segmentation. Hop-by-hop VRF-Lite can provide similar forwarding separation, but it becomes operationally heavy as the number of VRFs grows because each trunk, routing process, and interface association must be configured and maintained manually. Multihop MPLS can scale, but it introduces provider-style complexity and may require features or skills beyond a typical campus requirement. Multihop IPsec tunneling is not an efficient campus segmentation solution for hundreds of virtual networks. Therefore, EVN is the recommended design for scalable Layer 3 virtualization with simpler configuration and management. Reference topics:
campus virtualization, Easy Virtual Network, VRF separation, scalable virtual networks, route isolation.
NEW QUESTION # 61 
Refer to the exhibit. An architect must design a resilient gateway solution based on these requirements:
* VLAN 10 and VLAN 11 support voice and video applications.
* Link and node failures must have minimal impact on traffic.
* Provide protection against false hello packets.
* Support IPv6.
Which solution must the architect choose?
Answer: A
NEW QUESTION # 62
Which function are fabric intermediate nodes responsible for in an SD-Access Architecture?
Answer: D
Explanation:
Intermediate nodes are part of the Layer 3 network used for interconnections among the devices operating in a fabric role such as the interconnections between border nodes and edge nodes.
These interconnections are created in the Global Routing Table on the devices and is also known as the underlay network.

NEW QUESTION # 63
Which OSPF area blocks LSA Type 3, 4 and 5, but allows a default summary route?
Answer: A
Explanation:
A totally stubby area does not flood network summary LSAs (Type 3). It stifles Type 4 LSAs, as well. Like regular stub areas, totally stubby areas do not flood Type 5 LSAs. A totally stubby area sends just a single LSA for the default route.
