NEW QUESTION # 16
Which two border nodes are available in the Cisco SD-Access architecture? (Choose two.)
Answer: A,B
Explanation:
There are 3 types of border nodes in SD-Access:
External. Default exit from fabric with no specific routes injection
Internal. Gateway only for a set of networks, such as shared services prefixes Anywhere. Combination of external and internal functionality
NEW QUESTION # 17
Drag and drop the descriptions from the left onto the Cisco SD-WAN component they describe on the right.
Answer:
Explanation:
Explanation:
WAN Edge: traffic forwarding, security, encryption, QoS, and routing protocols; vSmart: distributes routes and policy information via OMP; vManage: centralized provisioning and simplified network changes; vBond:
communication for devices behind NAT.
The Cisco SD-WAN component mapping follows the normal separation of management, control, orchestration, and data-plane roles. WAN Edge routers are the data-plane devices at branches, data centers, campuses, or cloud edges. They forward user traffic and apply routing, QoS, encryption, segmentation, and security services. vSmart controllers provide the centralized control plane and distribute reachability and policy information with OMP, including prefixes, TLOCs, and service routes. vManage is the management- plane system; it supplies centralized provisioning, device templates, policy configuration, software lifecycle functions, monitoring, and operational visibility. vBond operates as the orchestration-plane component, authenticating devices during onboarding and helping devices behind NAT discover and establish the correct secure control connections. This separation is critical in enterprise design because each component has different redundancy, reachability, and scale requirements. The architect should not blur vManage and vSmart roles: vManage configures and monitors, while vSmart computes and distributes control policy. Reference topics: Cisco Catalyst SD-WAN architecture, WAN Edge data plane, vSmart OMP, vManage management plane, vBond orchestration.

NEW QUESTION # 18
Which design achieves SD-WAN control plane redundancy?
Answer: C
Explanation:
SD-WAN control plane redundancy can be achieved by using multiple instances of the vManage management system in clusters. Clustering vManage instances provides high availability and redundancy for the control plane, ensuring that if one vManage instance fails, another can take over without service interruption.
NEW QUESTION # 19
Refer to the exhibit.
Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)
Answer: A,D
NEW QUESTION # 20
Which two best practices must be followed when designing an out-of-band management network? (Choose two.)
Answer: C,E
Explanation:
An OOB management network should be deployed using the following best practices:
- Provide network isolation
- Enforce access control
- Prevent data traffic from transiting the management network
