NEW QUESTION # 113
Refer to the exhibit. A company has some offices that are connected via dark fiber in New York. A network architect must optimize the network design based on the EIGRP routing protocol. The network has hierarchical addressing between 10 and 12 routers in each office. Routing convergence time must be at the minimum. What must the network architect do to reduce the query range?
Answer: C
NEW QUESTION # 114
An architect is designing a network for an enterprise site. The design must use an active/backup design for the WAN. It must guarantee the SLA for several applications regardless of which connection is used. Which deployment model should the architect choose?
Answer: C
Explanation:
An MPLS WAN from two separate ISPs is the strongest fit when the enterprise requires an active/backup WAN design with guaranteed SLAs for applications on either connection. MPLS VPN services are typically delivered with provider-backed service-level commitments for latency, jitter, packet loss, and availability, which is why they are selected for predictable enterprise application transport. Using two separate MPLS providers improves resiliency against a provider failure while preserving SLA-backed behavior on the backup path. A hybrid MPLS and Internet VPN model can be cost effective, but the Internet path generally does not provide the same deterministic SLA unless enhanced by a specific managed service contract. Internet from two providers improves reachability diversity but does not inherently guarantee application SLA. A single ISP hybrid design creates a provider dependency and weakens availability. Therefore, dual-provider MPLS is the conservative design for guaranteed active/backup WAN service. Reference topics: MPLS WAN design, service-level agreements, active/backup WAN, provider diversity, application performance assurance.
NEW QUESTION # 115
What is the main purpose of the Cisco SD-Access overlay design?
Answer: D
Explanation:
The main purpose of the Cisco SD-Access overlay design is to enable the virtualized fabric services that run over the physical underlay. Cisco describes the overlay as the logical network created on top of the routed underlay, using virtual networks to provide segmentation and policy separation. SD-Access uses LISP for endpoint-to-location mapping and VXLAN for data-plane encapsulation, allowing Layer 2 and Layer 3 services to be delivered across a stable Layer 3 transport. Option C is the best available answer because the overlay exists to integrate and carry SD-Access services such as virtual networks, endpoint mobility, macrosegmentation, and security group policy. Simplified troubleshooting and visibility are management and assurance outcomes, not the overlay's main technical purpose. High availability depends on the underlay topology, node redundancy, and control-plane design, but it is not the primary definition of overlay design.
Reference topics: SD-Access overlay, virtual networks, LISP, VXLAN, segmentation, fabric services.
NEW QUESTION # 116
Which two routing protocols allow for unequal cost load balancing? (Choose two.)
Answer: A,B
Explanation:
EIGRP supports unequal cost load balancing through a feature called Variance. Variance allows EIGRP to include routes in the routing table that have a higher metric than the minimum metric route, but within a specified multiple (the variance value). This allows traffic to be distributed across multiple paths with different costs, thereby providing unequal cost load balancing.
BGP also supports unequal cost load balancing, although it's not as commonly used as in EIGRP. BGP can be configured to install multiple paths to a destination in the routing table and distribute traffic across these paths. This can be done using features like "Add-Path" or through careful configuration of BGP attributes such as weight, local preference, and MED (Multi-Exit Discriminator) to influence path selection and achieve load balancing across paths with different costs.
NEW QUESTION # 117
Exhibit:
Answer: C
Explanation:
R3 must be made an L1/L2 router so that it can connect the Level 1 area to the Level 2 backbone. IS-IS uses a two-level hierarchy. Level 1 routers know the topology inside their local area, Level 2 routers form the backbone between areas, and Level 1/Level 2 routers provide the boundary between the two. A proper IS-IS backbone cannot have isolated Level 1-only routers positioned between L1/L2 routers that need to exchange interarea reachability. If the link failure exposed an area-continuity problem, converting R3 to L1/L2 gives the area an appropriate attachment point to the backbone and restores interarea forwarding behavior. Making an unrelated router Level 1 or Level 2 only would not necessarily create the required boundary function. Simply making Area 0 L2-only is also not the focused fix if the topology still lacks a correct L1/L2 transition point.
The design principle is straightforward: every Level 1 area must have a dependable L1/L2 router through which traffic can reach destinations outside the area. Reference topics: IS-IS Level 1, Level 2 backbone, L1
/L2 routers, interarea reachability, hierarchical IGP design.
