  Which two commands download and execute an Apache web server container in Docker with a port binding 8080 in the container to 80 on the host? (Choose two.)

  A. docker pull apache

  B. docker run 璸 8080:80 httpd

  C. docker run 璸 80:8080 httpd

  D. docker pull httpd

  E. docker pull https

  Correct Answer: CD

  To download and run an Apache web server container in Docker with a port binding of 8080 in the container to port 80 on the host, you can use the following two commands:

  1. docker pull httpd:latest - This command will download the latest version of the Apache web server Docker image from the Docker Hub.

  2. docker run -p 80:8080 -d httpd - This command will start a new container based on the httpd image, with a port binding of 8080 in the container to port 80 on the host.

  The -d flag runs the container in detached mode, meaning it will run in the background and not block the terminal.

• Question 215:

  Refer to the exhibit.

  

  A network engineer must configure new interfaces on a set of devices and is planning to use an Ansible playbook for the task. All devices support SSH and NETCONF protocol, and the interface variables are unique per device. In which directory are the YAML files including variables hosted to automate the task with the netconf_config module?

  A. current working directory

  B. host_vars directory

  C. group_vars directory

  D. home directory

  Correct Answer: B

  Generally speaking, this is not the best way to define variables that describe your system policy. Setting variables in the main inventory file is only a shorthand. See Organizing host and group variables for guidelines on storing variable values in individual files in the `host_vars' directory.

• Question 216:

  Which protocol is used for clock synchronization between network devices?

  A. FTP

  C. BGP

  D. NTP

  Correct Answer: D

  Refer to the exhibit.

  

  Up to which device does the communication server 1 and server 2 go?

  A. device B

  B. device C

  C. device D

  D. device E

  Correct Answer: C

  Since servers are in different networks, they need a router to communicate. The router does not send the packets to the firewall because the next hop is on the same interface that connects down to the servers.

• Question 220:

  Refer to the exhibit.

  

  An engineer sends the request to collect data over Cisco AMP for Endpoints API. The Engineer must list guide and hostname data for all computers, but the first request returns only 500 items out of 2,000. Then, the engineer adds the loop to collect all the data. What must be added to the script where the code is missing to complete the requests?
