  B. Build the package.yaml file.

  C. Build the package.cert file to sign the app ,

  D. Log in to Device Manager.

  Correct Answer: B

• Question 333:

  An application has initiated an OAuth authorization code grant flow to get access to an API resource on behalf of an end user.

  Which two parameters are specified in the HTTP request coming back to the application as the end user grants access? (Choose two.)

  A. access token and a refresh token with respective expiration times to access the API resource

  B. access token and expiration time to access the API resource

  C. redirect URI a panel that shows the list of permissions to grant

  C. 2

  D. version 2

  Correct Answer: C

• Question 337:

  What is a characteristic of a monolithic architecture?

  A. It is an application with multiple independent parts.

  B. New capabilities are deployed by restarting a component of the application.

  C. A service failure can bring down the whole application.

  D. The components are platform-agnostic.

  Correct Answer: C

  Explanation: A monolitic app can be platform-agnostic but it's not mandatory. But is the app is monolitic, a service failure (such as storage or network) will bring down the whole app/service. This is unlike the distributed application architecture where failure of one microcomponent can be detected and fixed dynamically.

• Question 338:

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: D

• Question 339:

  A heterogeneous network of vendors and device types needs automating for better efficiency and to enable future automated testing. The network consists of switches, routers, firewalls and load balancers from different vendors, however they all support the NETCONF/RESTCONF configuration standards and the YAML models with every feature the business requires. The business is looking for a buy versus build solution because they cannot dedicate engineering resources, and they need configuration diff and rollback functionality from day 1.

  Which configuration management for automation tooling is needed for this solution?

  A. Ansible

  B. Ansible and Terraform

  C. NSO

  D. Terraform

  E. Ansible and NSO
