• Question 61:

  What is a benefit of version control?

  A. prevents two users from working on the same file
  B. keeps track of all changes to the files
  C. prevents the sharing of files
  D. keeps the list of data types used in the files
  B. keeps track of all changes to the files

  ---

  Explanation Explanation/Reference:Version control systems (VCS) are essential for managing changes to code and files in a project. They track all modifications, enabling multiple users to work collaboratively while maintaining a history of changes. Tracking Changes: VCS keeps a detailed history of changes made to files, including who made the change and when. Collaboration: Multiple users can work on the same project simultaneously without overwriting each other's work. Reverting Changes: It allows reverting to previous versions if a mistake is made. Option B is correct as it highlights the primary benefit of version control--keeping track of all changes to the files. Cisco DevNet Documentation: Version Control with Git

• Question 62:

  Calling a REST API returns a 404 error. What does this code represent?

  A. A query parameter is missing.
  B. The URI being requested is incorrect.
  C. A header is missing.
  D. The payload is formatted incorrectly.
  B. The URI being requested is incorrect.

• Question 66:

  Refer to the exhibit. The YANG module devnet-users shows a data model for user accounts. Which code snippet shows the XML representation of an instantiation of the YANG data model?

  

  

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

• Question 67:

  Which protocol is used for clock synchronization between network devices?

  A. FTP
  B. NNTP
  C. BGP
  D. NTP
  D. NTP

  ---

  NTP (Network Time Protocol) is the protocol used for clock synchronization between network devices. It synchronizes the clocks of computers and network devices to ensure that all devices in a network have the same time, which is crucial for logging events, security protocols, and coordinating time-sensitive operations. Reference: Cisco DevNet Associate documentation on NTP and its role in network synchronization.

• Question 68:

  What are the two principles of an infrastructure as code environment? (Choose two)

  A. Complete complex systems must be able to be built from reusable infrastructure definitions.
  B. Environments must be provisioned consistently using the same inputs.
  C. Redeployments cause varying environment definitions.
  D. Service overlap is encouraged to cater for unique environment needs.
  E. Components are coupled, and definitions must be deployed for the environment to function.
  A. Complete complex systems must be able to be built from reusable infrastructure definitions.
  B. Environments must be provisioned consistently using the same inputs.

• Question 69:

  Refer to the exhibit.

  

  While developing a Cisco Webex bot, an application reaches the public IP address of the firewall, but traffic is forwarded to the IP address of server 1 instead of the IP address of server 2. What causes this issue?

  A. The proxy server that rewrites traffic is misconfigured.
  B. The router is sending the traffic to server 1 instead of server 2.
  C. The switch is forwarding IP traffic to the wrong VLAN.
  D. NAT is misconfigured on the firewall.
  D. NAT is misconfigured on the firewall.

  ---

  Explanation Explanation/Reference:Network Address Translation (NAT) on the firewall is responsible for translating the public IP address to the private IP addresses of internal servers. If traffic is being forwarded to the wrong server, it indicates a misconfiguration in the NAT rules. NAT Configuration: NAT rules need to be correctly configured to forward traffic to the appropriate internal server based on the destination IP and port. Misconfiguration: If NAT rules are incorrect, traffic may be directed to the wrong internal IP address, as seen in the exhibit where traffic is sent to server 1 instead of server 2. Option D is correct as the issue is caused by NAT misconfiguration on the firewall. Cisco DevNet Documentation: Configuring NAT

• Question 70:

  Which two factors reduce the experience of an application? (Choose two.)

  A. source location
  B. traffic class
  C. packet loss
  D. network latency
  E. usage
  C. packet loss
  D. network latency
