When DevOps practices are integrated into an existing organization, which two characteristics are positive indicators of DevOps maturity? (Choose two.)

  1. mean time between success
  2. mean time to recover
  3. cone testing
  4. change lead time
  5. age of codebase

Answer(s): B,D

Explanation:

Change lead time is the amount of time it takes for a proposed change to go from the idea phase to being fully deployed in production. This metric can be used to measure the speed and efficiency with which changes are implemented, which is often indicative of an organization's DevOps maturity. Mean time to recover (MTTR) is the average amount of time it takes to restore a service or application to its working state when an issue arises. MTTR is an important metric for measuring the resilience of an organization's infrastructure, and is another indicator of DevOps maturity. (Source:

Which two statements about Infrastructure as Code are true? (Choose two.)

  1. Test-driven development practices make use of Infrastructure as Code.
  2. Infrastructure as Code refers to automated testing libraries.
  3. DevOps builds upon Infrastructure as Code.
  4. Infrastructure as Code is based on practices from software development.
  5. Infrastructure as Code must use the same programming language as the application.

Answer(s): C,D

Explanation:

(IaC) is a practice that allows for the automation of infrastructure configuration and deployment, allowing DevOps teams to deploy and manage infrastructure with the same release pipelines and versioning as source code [1]. IaC is based on practices from software development, and promotes the use of automation and repeatable processes to ensure consistency of deployments.



Refer to the exhibit.



The exhibit shows the output of an Ansible task that prints the contents of the
show_ip_int_brief variable that was registered in a different task in the playbook.

Which expression is used to print the output of the command without its header row?

  1. show_ip_int_brief[`stdout_lines'][0]
  2. show_ip_int_brief[`stdout_lines'][1:]
  3. show_ip_int_brief[`stdout_lines'][0][1:]
  4. show_ip_int_brief[`stdout_lines']

Answer(s): C

Explanation:

---
show_ip_int_brief["~stdout_lines'][0][1:]
---
stdout_lines - nested list,
[0], first element of above nested list (extract of all header + interfaces, coma separated for individual elements),
[1:] - 2nd, 3rd, 4th line of the above sub-list.



Fill in the blanks to describe the concepts of extending DevOps practices to the network for NetDevOps.

NetDevOps builds and manages networks as a system that enables network services to be consumed in a DevOps approach. Organizations practicing NetDevOps see changes in the__________ as routine and expected activities, with a well-defined and practiced process for_____________, testing, and _____________ network changes. By making them routine, network changes can be small and simple.

  1. network, designing, deploying

Answer(s): A
