• Question 471:

  Refer to the exhibit.

  

  A network engineer makes a RESTCONF API call to Cisco IOS XE to retrieve information. Which HTTP method and URL does the engineer use to make the API call?

  A. GET https://devnetlab.local/restconf/api/running/native/GigabitEthernet
  B. GET https://devnetlab.local/restconf/api/running/native/interface/GigabitEthernet
  C. GET https://devnetlab.local/restconf/api/running/native/interface/GigabitEthernet/2/
  D. GET https://devnetlab.local/restconf/api/running/ios/native/interface/GigabitEthernet/1/
  C. GET https://devnetlab.local/restconf/api/running/native/interface/GigabitEthernet/2/

  ---

  The provided JSON configuration includes information about a GigabitEthernet interface with the name "2". To retrieve information about this specific interface using a RESTCONF API call, the correct HTTP method and URL must be used. HTTP Method: The GET method is used to retrieve information from the server. Correct URL: The URL must specify the path to the particular interface. The correct URL structure includes the native and interface resources, followed by the interface type (GigabitEthernet) and its specific name ("2"). The correct RESTCONF API call to retrieve the information would be: GET https://devnetlab.local/restconf/api/running/native/interface/GigabitEthernet/2/ This URL correctly targets the specific GigabitEthernet interface named "2" in the running configuration.

  C. A YAML file is created.
  D. A YAML file is removed.
  E. A directory called state.yml is created.
  A. A directory called PRODUCTION is created.
  C. A YAML file is created.

  The bash script in the exhibit performs the following actions step-by-step: #!/bin/bash - This is the shebang line that tells the system this script should be run with the bash shell. apt-get update - This command updates the package lists for upgrades for packages that need upgrading, as well as new packages that have just come to the repositories. apt-get -y install git - This command installs git automatically confirming the installation with -y. cd Code/Network_Config - This command changes the directory to Code/Network_Config. mkdir PRODUCTION - This command creates a new directory named PRODUCTION. cd PRODUCTION - This command changes the directory to the newly created PRODUCTION directory. touch state.yml - This command creates an empty file named state.yml. vi state.yml - This command opens the state.yml file in the vi editor. Therefore, based on the above script analysis: A directory called PRODUCTION is created (Answ

• Question 473:

  Which CI/CD component allows for the storing of code packages and enables the testing of the same code that is running on the live system?

  A. Artifactory
  B. Jira
  C. ITSM
  D. Git
  A. Artifactory

  ---

  Explanation Explanation/Reference:"Git is used for source code and Artifactory is used for the binaries which go with the source code." Source: https://foxutech.medium.com/what-is-jfrog-artifactory-its-component-and-features-d0dbe85482ff

• Question 474:

  Refer to the exhibit.

  A. README.md
  B. setup.py
  C. axl.py
  D. ciscoaxl.py

  A. SSH
  B. NETCONF
  C. HTTP
  D. Telnet
  D. Telnet

• Question 476:

  Refer to the exhibit. A developer cannot reach the web application behind an NGINX load balancer. The developer sends a request to an application FQDN with cURL but gets an HTTP 502 response. Which action solves the problem?

  

  A. Fix errors in the server configuration, which is behind the load balancer.
  B. Bring up the load balancer to the active state.
  C. Fix errors in the cURL request sent by the client.
  D. Change the default gateway on the load balancer to an active one.
  A. Fix errors in the server configuration, which is behind the load balancer.

  ---

  An HTTP 502 Bad Gateway error indicates that the server acting as a gateway or proxy received an invalid response from the upstream server. This suggests there may be an issue with the configuration or availability of the server behind the load balancer. HTTP 502 Error: This error occurs when the load balancer or gateway receives an invalid response from the backend server. Server Configuration: The issue is likely due to misconfiguration or problems with the backend server that needs to be resolved. Option A is correct as it identifies that the issue lies with the server configuration behind the load balancer. NGINX Documentation: Troubleshooting 502 Errors

• Question 477:

  Which HTTP method is used by webhooks and notifies a listener about an event change?

  A. PUT
  B. POST
  C. PATCH
  D. GET
  B. POST

  ---

  Webhooks typically use the HTTP POST method to notify a listener about an event change. When an event occurs, the source system sends an HTTP POST request to the listener's URL with the details of the event, allowing the receiving system to process and respond to the event.

• Question 478:

  What is the well-known port for HTTPS?

  A. 81
  B. 443
  C. 80
  D. 440
  B. 443

  Port 443 is specifically designated for HTTPS (Hypertext Transfer Protocol Secure), which uses Transport Layer Security (TLS) or Secure Sockets Layer (SSL) to encrypt the communication between a web server and a client, ensuring the security and privacy of the data being transmitted. This makes it the preferred port for accessing websites that require secure communication, such as online banking, e-commerce, and social media platforms.
