NEW QUESTION # 72
Which type of rendezvous point deployment is standards-based and support dynamic RP discovery?
Answer: A
NEW QUESTION # 73
Drag and drop the characteristics from the left onto the YANG modules they describe on the right. Not all options are used.
Answer:
Explanation:
Explanation:
The YANG module mapping follows the distinction between standards-based, vendor-neutral, and vendor- native data models. IETF YANG models are standards-driven and are appropriate when the design goal is protocol-level interoperability across vendors for common network functions. OpenConfig models are also vendor-neutral, but they are developed by the OpenConfig community and commonly use a structured separation between intended configuration and operational state. Cisco native models expose platform- specific Cisco IOS XE, IOS XR, or NX-OS capabilities and are often the most complete option when a feature is unique to a Cisco operating system. The selected drag-and-drop answer aligns each characteristic with the model family that owns that behavior. In a professional automation design, the engineer should not choose a model only because it is familiar. The correct choice depends on feature coverage, device support, platform release, schema stability, and whether the workflow must operate consistently across vendors. For multivendor intent, choose IETF or OpenConfig first; for Cisco-specific feature depth, use Cisco native models. Reference topics: YANG, IETF models, OpenConfig, Cisco native models, NETCONF and RESTCONF automation.
NEW QUESTION # 74
Drag and drop the characteristics from the left onto the correct telemetry mode on the right.
Answer:
Explanation:
Explanation
In a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed. Dialin mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a session to the destinations based on the subscription. All 64-bit IOS XR platforms (except for NCS 6000 series routers) support gRPC and TCP protocols. All 32-bit IOS XR platforms support only TCP.
NEW QUESTION # 75 
Refer to the exhibit An architect is designing an IPv4 plan using the 172 20 0.0/16 network The design must maximize the number of subnets and minimize the number of wasted IP addresses In addition, the plan must allocate a subnet to these customers and links
* Customer A, which supports 125 hosts
* Customer D, which supports 62 hosts
* Links B C. and E
Which two configuration sets meet these requirements ' ? (Choose two)
Answer: C,E
Explanation:
The selected configuration sets are correct because the addressing plan must use VLSM to maximize subnets and minimize wasted addresses. Customer A requires 125 hosts, so it needs a /25 subnet, which provides 126 usable host addresses. Customer D requires 62 hosts, so it needs a /26 subnet, which provides 62 usable addresses exactly. Point-to-point or small WAN links B, C, and E should use the smallest appropriate link subnets shown in the exhibit, typically /30 for IPv4 point-to-point links when two usable addresses are required. A correct plan must allocate the largest blocks first, align every subnet on the proper boundary, avoid overlap, and avoid assigning a larger-than-needed subnet to any customer or link. Options A and C are the two valid combinations that satisfy those rules in the exhibit. Any option that places a /25 or /26 on the wrong boundary, overlaps with another block, or wastes larger subnets on links would fail the design objective. Reference topics: IPv4 VLSM, subnet boundary alignment, host capacity planning, point-to-point addressing, route summarization readiness.
NEW QUESTION # 76 
Refer to the exhibit. An architect is designing a network that requires route redistribution. The design must prevent route feedback and the creation of routing loops. The OSPF domain is using default metrics, and the IS-IS domain is using narrow metrics. Which solution must the architect select?
Answer: C
