NEW QUESTION # 61
Which two results occur if Cisco DNA center loses connectivity to devices in the SD-ACCESS fabric?
(Choose two)
- A. All devices reload after detecting loss of connection to Cisco DNA Center
- B. User connectivity is unaffected
- C. Cisco DNA Center is unable to collect monitoring data in Assurance
- D. Users lose connectivity
- E. Already connected users are unaffected, but new users cannot connect
Answer: B,E
Explanation:
When Cisco DNA Center loses connectivity to devices in the SD-ACCESS fabric, already connected users remain unaffected, ensuring continuous user connectivity (B). However, new users cannot connect due to the loss of communication with Cisco DNA Center . The devices do not reload simply because of the lost connection (A), and while Cisco DNA Center cannot collect monitoring data in Assurance (D), this does not directly affect user connectivity. Users also do not lose connectivity (E) as the fabric continues to function for existing connections.

/dna/intent/api/v1 /template-programmer/project
What does the code mean?
- A. The request accepted for processing, but the processing was not completed.
- B. The client made a request a resource that does not exist.
- C. The POST/PUT request was fulfilled and a new resource was created, Information about the resource is in the response body.
- D. The server has not implemented the functionality that is needed to fulfill the request.

resource but may be available in the future. Subsequent requests by the client are permissible.
NEW QUESTION # 63
Which protocol is implemented to establish secure control plane adjacencies between Cisco SD-WAN nodes?
- A. IKF
- B. ESP
- C. TLS
- D. IPsec
Answer: C
Explanation:
The protocol used to establish secure control plane adjacencies between Cisco SD-WAN nodes is TLS (Transport Layer Security). In the Cisco SD-WAN architecture, TLS provides a secure channel for control plane traffic between the various SD-WAN components, ensuring both privacy and data integrity. This is critical for maintaining a secure network environment, especially when transmitting sensitive information across the control plane.
NEW QUESTION # 64
Which protocol does REST API rely on to secure the communication channel?
- A. SSH
- B. TCP
- C. HTTP
- D. HTTPS
Answer: D
Explanation:
The REST API accepts and returns HTTP (not enabled by default) or HTTPS messages that contain JavaScript Object Notation (JSON) or Extensible Markup Language (XML) documents. You can use any programming language to generate the messages and the JSON or XML documents that contain the API methods or Managed Object (MO) descriptions.

In a Cisco SD-Access network architecture, which access layer cabling design is optimal for the underlay network?
- A. Switches are connected to each upstream distribution device.
- B. Switches are connected to each upstream distribution and core device.
- C. Switches are cross-linked at the same layer and have a single connection to each upstream distribution device.
- D. Switches are cross-linked to devices at the same layer and at the upstream and downstream devices.
Answer: C
Explanation:
In a Cisco SD-Access network architecture, the optimal cabling design for the underlay network is to have switches cross-linked at the same layer with a single connection to each upstream distribution device. This design supports redundancy and efficient traffic flow1.

NEW QUESTION # 75
A GRE tunnel is down with the error message %TUN-5-RECUR DOWN:
Which two options describe possible causes of the error? (Choose two)
- A. The tunnel destination is being routed out of the tunnel interface
- B. The tunnel mode and tunnel IP address are misconfigured
- C. Incorrect destination IP addresses are configured on the tunnel
- D. There is link flapping on the tunnel
- E. There is instability in the network due to route flapping
Answer: A,E
Explanation:
Explanation
The %TUN-5-RECURDOWN: Tunnel0 temporarily disabled due to recursive routing error message means that the generic routing encapsulation (GRE) tunnel router has discovered a recursive routing problem. This condition is usually due to one of these causes:
+ A misconfiguration that causes the router to try to route to the tunnel destination address using the tunnel interface itself (recursive routing)
+ A temporary instability caused by route flapping elsewhere in the network

A company plans to implement intent-based networking in its campus infrastructure. Which design facilities a migrate from a traditional campus design to a programmer fabric designer?
- A. routed access
- B. three-tier
- C. two-tier
- D. Layer 2 access
Answer: C
Explanation:
Explanation
Intent-based Networking (IBN) transforms a hardware-centric, manual network into a controller-led network that captures business intent and translates it into policies that can be automated and applied consistently across the network. The goal is for the network to continuously monitor and adjust network performance to help assure desired business outcomes. IBN builds on software-defined networking (SDN). SDN usually uses spine-leaf architecture, which is typically deployed as two layers: spines (such as an aggregation layer), and leaves (such as an access layer).
