• Question 372:

  Refer to the exhibit. An application must be deployed on a server that has other applications installed. The server resources are to be allocated based on the deployment requirements. The OS for each application must be independent. Which type of deployment is used?

  

  A. hybrid
  B. virtual machines
  C. containers
  D. bare metal
  B. virtual machines

  ---

  The exhibit shows an architecture where each application runs in its own isolated environment with its own OS. This setup is typical of virtual machines (VMs), where multiple VMs can run on a single physical server managed by a hypervisor. Isolation: VMs provide complete isolation between applications, including independent operating systems. Resource Allocation: Resources such as CPU, memory, and storage can be allocated based on deployment requirements. Option B is correct as the type of deployment used is virtual machines.

• Question 373:

  Refer to the exhibit.

  

  The documentation outlines how to use credentials for the AMP API. Which script successfully performs an API call using basic authentication?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

  Refer to the exhibit.

  

  Which function does the EXPOSE line perform when building an image from this Dockerfile?

  A. Local port 8080 of the container that launched with this docker image is accessible from co-hosted containers and external clients.
  B. Local port 8080 is not reachable at all because no IP address is specified along with the EXPOSE command of the Dockerfile.
  C. Local port 8080 is accessible from other containers running on the same docker host as the container that launched with this docker image.
  D. Local port 8080 of the container that launched with this docker image is accessible to external clients.
  C. Local port 8080 is accessible from other containers running on the same docker host as the container that launched with this docker image.

  Explanation Explanation/Reference:By default, the EXPOSE instruction does not expose the container's ports to be accessible from the host. In other words, it only makes the stated ports available for inter-container interaction. Whereas publishing a port using either -P or -p exposes it, exposing a port using EXPOSE or Expose does not publish it. So, while exposed ports can only be accessed internally, published ports can be accessible by external containers and services. https://www.whitesourcesoftware.com/free-developer-tools/blog/docker-expose-port/

• Question 376:

  DRAG DROP

  Drag and drop the Dockerfile instructions from the left onto the descriptions on the right. Not all options are used.

• Question 377:

  Which service provides a directory lookup for IP addresses and host names?

  A. DNS
  B. NAT
  C. SNMP
  D. DHCP
  A. DNS

• Question 378:

• Question 379:

  Refer to the exhibit.

  

  The IT team deployed a new Linux virtual machine for a software engineer to use, but the engineer is not comfortable configuring services using Bash. Which workflow is automated by the Ansible playbook?

  A. Restart the network on the eth0 interface and start the httpd service if it is not already started.
  B. Restart the httpd service and start the network service for the eth0 interface.
  C. Start the network service on the eth0 interface even if it was brought down manually.
  D. Restart the httpd service and the network service regardless of the state.
  A. Restart the network on the eth0 interface and start the httpd service if it is not already started.

  ---

  The Ansible playbook in the exhibit consists of two stages: Stage 1: Restarts the network service on the eth0 interface. Stage 2: Starts the httpd service. Stage 1: -name: stage1 ansible.builtin.service: name: network state: restarted args: eth0 This stage ensures that the network service on the eth0 interface is restarted. Stage 2: -name: stage2 ansible.builtin.service: name: httpd state: started This stage ensures that the httpd service is started if it is not already running.

• Question 380:

  A developer plans to deploy a new application that will use an API to implement automated data collection from Webex with these requirements:

  1.

  The application was created by using the request library.

  2.

  Requires HTTP basic authentication.

  3.

  Provides data in JSON or XML formats.

  Which Cisco DevNet resource helps the developer with how to use the API?

  A. DevNet sandbox
  B. API documentation
  C. forums
  D. DevNet code exchange
  B. API documentation

  ---

  The developer can use the Cisco DevNet API documentation to get detailed information on how to use the API for automated data collection from Webex. The API documentation includes comprehensive guides, usage examples, and authentication methods such as HTTP basic authentication. This resource helps developers understand the data formats (JSON or XML) and provides code snippets and best practices for implementation. Cisco DevNet API documentation is designed to assist developers in integrating their applications with Cisco's APIs effectively. Reference: Cisco DevNet API Documentation
