NEW QUESTION # 30 
Refer to the exhibit. A RESTCONF GET request is sent to a Cisco IOS XE device. The base URL of the request and the response in XML format are shown in the exhibit. What are the two YANG data nodes and modules referenced in the response? (Choose two.)
- A. address is a container defined in the ietf-interfaces module
- B. The ethernetCsmacd type is imported from the iana-if-type module
- C. description is a key field defined in the interface list
- D. interface has the YANG data node type of container
- E. ipv4 is a container defined in the ietf-ip module
Answer: B,E
Explanation:
* B. The ethernetCsmacd type is imported from the iana-if-type module: This is correct because the XML response shows <type xmlns="urn:ietf:params:xml:ns:yang:iana-if-type">ethernetCsmacd</type>, indicating that the ethernetCsmacd type is defined within the iana-if-type module.
* D. ipv4 is a container defined in the ietf-ip module: This is accurate as the XML response includes <ipv4 xmlns="urn:ietf:params:xml:ns:yang:ietf-ip">, which specifies that ipv4 is a container within the ietf-ip module.

NEW QUESTION # 33
What is an advantage of software-defined networks as compared to traditional networks?
- A. They deliver a distributed management architecture that provides better resilience to errors.
- B. They simplify operations by creating a concrete copy of the network.
- C. They reduce complexity by coupling the control and the data plane.
- D. They enable older hardware to be repurposed without an investment in new infrastructure.
Answer: A
Explanation:
Software-defined networks (SDNs) offer several advantages over traditional networks; one key advantage is their distributed management architecture. Unlike traditional networks where the control plane (which makes decisions about where traffic should be sent) and the data plane (which actually sends packets according to those decisions) are coupled on each networking device leading to potential single points of failure, SDNs separate these planes. This separation allows for centralized control with a global view of the network state while maintaining local data forwarding at each switch. This architecture enhances resilience as it can dynamically adjust and reroute traffic around failed nodes or congested paths without manual intervention.

NEW QUESTION # 35
Refer to the exhibit.
A RESTCONF GET request is sent to a Cisco IOS XE device. A portion of the response is shown in the exhibit.
Which module name corresponds to the YANG model referenced in the request?
- A. ietf-interfaces:ietf-ipv4
- B. ietf-interfaces
- C. ietf-interfaces:interfaces
- D. iana-if-type:ethernetCsmacd
Answer: A
NEW QUESTION # 36 
Refer to the exhibit. What is a characteristic of the tree?
- A. two leaf-lists
- B. three optional metrics
- C. three containers
- D. ten leaf-lists
Answer: C
Explanation:
The YANG module tree diagram represents the data model for network configuration and state data used by management protocols like NETCONF and RESTCONF. In this diagram, containers are denoted by curly braces {} and represent groupings of related data within the model. The three containers identified in the image are "interface," "statistics," and "discontinuity-time," which organize related configuration or state information.

NEW QUESTION # 40
Which two API calls must be issued to attach a device template in Cisco SD-WAN? (Choose two.)
- A. GET call to initiate the attach action
- B. "monitor device action status" GET API request with the device ID to display the status of the attach action
- C. PUT call to initiate the attach action
- D. "monitor device action status" GET API request with the process ID to display the status of the attach action
- E. POST call to initiate the attach action
Answer: D,E
Explanation:
To attach a device template in Cisco SD-WAN, you must issue a POST call to initiate the attach action. This is the first step in the process. After initiating the attach action, you need to monitor the status of the action.
For this, you issue a "monitor device action status" GET API request with the process ID. The process ID is used to track the status of the attach action until it is completed.

NEW QUESTION # 43
What are two characteristics of REST API calls? (Choose two.)
- A. Stateless
- B. Parameters passed in the headers
- C. Unencrypted
- D. Implemented over http
- E. Non-cacheable
Answer: A,D
Explanation:
REST API calls are characterized as being stateless and implemented over HTTP. Being stateless means that each request from client to server must contain all of the information needed to understand and complete the request; there is no session state stored on the server. Implemented over HTTP indicates that REST APIs use standard web protocols for communication. References: Automating Cisco Enterprise Solutions Official Cert Guide
