2. Question 1082 · 1334 in bank

   What is the function of `off-the-shelf` switches in a controller-based network?

   • Asetting packet-handling policies
   • Bforwarding packets
   • Cproviding a central view of the deployed network
   • Dmaking routing decisions

   Show answer

   Answer: B

   Explanation

   In a controller-based network, `off-the-shelf` switches primarily function to **forward packets**. They are controlled by an SDN controller, which takes the computational complexity away from the SDN network devices. This makes the switches more "commoditized", which is a synonym for lower costs. Therefore, the correct answer is **B. forwarding packets**.

   Which REST method updates an object in the Cisco DNA Center Intent API?

   • ACHANGE
   • BUPDATE
   • CPOST
   • DPUT

   Show answer

   Answer: D

   Explanation

   The REST method that is typically used to update an object in the Cisco DNA Center Intent API is D. PUT. In RESTful APIs, different HTTP methods are used to perform different actions on resources. The PUT method is commonly used to update an existing resource or replace it entirely with a new representation. When using the Cisco DNA Center Intent API to update an object, you would typically send an HTTP request with the PUT method to the appropriate endpoint, providing the updated representation of the object in the request body. This allows you to modify the attributes or properties of the object and persist those changes in the system. Therefore, the correct answer is D. PUT

6. Question 1086 · 1334 in bank

   Which definition describes JWT in regard to REST API security?

   • Aan encrypted JSON token that is used for authentication
   • Ban encrypted JSON token that is used for authorization
   • Can encoded JSON token that is used to securely exchange information
   • Dan encoded JSON token that is used for authentication

   Show answer

   Answer: D

   Explanation

   D. an encoded JSON token that is used for authentication JSON Web Tokens (JWT) is an open standard for securely transmitting information between parties as a JSON object. In the context of REST API security, JWT is typically used for authentication purposes. It is a compact, URL-safe means of representing claims to be transferred between two parties. When a user authenticates with a REST API, the server generates a JWT token that contains user information, such as the user ID and access privileges. The token is then sent to the client, typically in the form of an HTTP header, and is included in subsequent requests to the API. The server then validates the token to ensure that it was issued by a trusted authority and that it has not been tampered with. If the token is valid, the server grants access to the requested resources. If the token is invalid or has expired, the server denies access to the resources. Therefore, the correct definition of JWT in regard to REST API security is that it is an encoded JSON token that is used for authentication.

7. Question 1087 · 1334 in bank

   

   Refer to the exhibit. What is identified by the word `switch` within line 2 of the JSON Schema?

   • Aarray
   • Bvalue
   • Cobject
   • Dkey

   Show answer

   Answer: D

   Explanation

   Here is an example of a key-value pair in JSON: {"name": "John"} In this example, "name" is the key and "John" is the value. The value is a string, and it is associated with the key "name". Here is another example of a key-value pair in JSON: {"age": 30} In this example, "age" is the key and 30 is the value. The value is a number, and it is associated with the key "age".

10. Question 1090 · 1334 in bank

    Which communication interaction takes place when a southbound API is used?

    • Abetween the SDN controller and PCs on the network
    • Bbetween the SDN controller and switches and routers on the network
    • Cbetween the SDN controller and services and applications on the network
    • Dbetween network applications and switches and routers on the network

    Show answer

    Answer: B

    Explanation

    The communication interaction that takes place when a southbound API is used is B. between the SDN controller and switches and routers on the network. In a software-defined networking (SDN) architecture, the control plane is centralized in an SDN controller, which manages and controls the behavior of network devices such as switches and routers. The southbound API is the interface through which the SDN controller communicates with these network devices. When using the southbound API, the SDN controller sends instructions and configuration commands to the switches and routers in the network. These instructions can include actions like modifying forwarding tables, setting up flow rules, configuring quality of service (QoS) parameters, and more. The switches and routers, acting as the data plane, receive and process the instructions from the controller, implementing the desired network behavior. They forward traffic based on the rules and configurations received from the controller. Therefore, the correct answer is B. between the SDN controller and switches and routers on the network.
