  A. cookbook

  B. task

  C. playbook

  D. model

  E. recipe

  Correct Answer: BC

  Ansible playbooks: “files that provide actions and logic about what Ansible should do.”

  “The playbook will list tasks and choices based on those results, like “Configure all branch routers in these locations, and if errors occur for any device, do these extra tasks for that device”.”

  A. Eliminating training needs

  B. Increasing reliance on self-diagnostic and self-healing

  C. Policy-derived provisioning of resources

  D. Providing a ship entry point for resource provisioning

  E. Reducing hardware footprint

  Correct Answer: CD

• Question 865:

  What is a characteristic of cloud-based network topology?

  A. wireless connections provide the sole access method to services

  B. onsite network services are provided with physical Layer 2 and Layer 3 components

  C. services are provided by a public, private, or hybrid deployment

  D. physical workstations are configured to share resources

  Correct Answer: C

• Question 866:

  A network analyst is tasked with configured the date and time on a router using EXEC mode. The date must be set to 12:00am. Which command should be used?

  A. Clock timezone

  B. Clock summer-time-recurring

  C. Clock summer-time date

  D. Clock set

  Correct Answer: D

• Question 867:

  Which HTTP status code is returned after a successful REST API request?

  A. 200

  B. 301

  C. 404

  D. 500

  Correct Answer: A

  In HTTP (Hypertext Transfer Protocol), status codes are used to indicate the outcome of a request. When a client (such as a web browser) makes a request to a server (such as a web server), the server responds with a status code and a

  message.

  A successful REST API request typically returns a status code of 200 (OK). This indicates that the request was successful and that the server was able to process it and provide a response.

  Here are some other common HTTP status codes:

  301 (Moved Permanently): This status code indicates that the requested resource has been permanently moved to a new location.

  404 (Not Found): This status code indicates that the requested resource could not be found.

  500 (Internal Server Error): This status code indicates that an error occurred on the server while processing the request.

  In summary, the HTTP status code returned after a successful REST API request is 200 (OK).

• Question 868:

  What is the function of a controller in controller-based networking?

  A. It serves as the centralized management point of an SDN architecture.

  B. It centralizes the data plane for the network.

  C. It is the card on a core router that maintains all routing decisions for a campus.

  D. It is a pair of core routers that maintain all routing decisions for a campus

  Correct Answer: A

  The function of a controller in controller-based networking is A. It serves as the centralized management point of an SDN (Software-Defined Networking) architecture . The controller is responsible for managing network devices and implementing network policies, as well as providing a central point of control and visibility for the entire network. It enables dynamic, programmatically efficient network configuration through the use of software-based controllers or a centralized controller with open APIs (Application Programming Interfaces) that communicate with network devices and applications . This promotes increased network agility, scalability, and flexibility in response to changing business needs.

• Question 869:

  Under which condition is TCP preferred over UDP?

  A. UDP is used when low latency is optimal, and TCP is used when latency is tolerable.

  B. TCP is used when dropped data is more acceptable, and UDP is used when data is accepted out-of-order.

  C. TCP is used when data reliability is critical, and UDP is used when missing packets are acceptable.

  D. UDP is used when data is highly interactive, and TCP is used when data is time-sensitive.

  Correct Answer: C

• Question 870:

  Refer to the exhibit.

  

  The entire contents or the MAC address table are shown. Sales-4 sends a data frame to Sales-1.

  

  What does the switch do as it receives the frame from Sales-4?

  A. Map the Layer 2 MAC address to the Layer 3 IP address and forward the frame.

  B. Insert the source MAC address and port into the forwarding table and forward the frame to Sales-1.

  C. Perform a lookup in the MAC address table and discard the frame due to a missing entry.

  D. Flood the frame out of all ports except on the port where Sales-1 is connected.

  Correct Answer: B
