NEW QUESTION 34
When DevOps practices are integrated into an existing organization, which two characteristics are positive indicators of DevOps maturity? (Choose two.)

cone testing

mean time to recover

mean time between success

age of codebase

change lead time

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.

NEW QUESTION 38
Refer to the exhibit.

An organization has issues with code-based failures after implementing a CI/CD pipeline to automate the builds and deployment phases of an application.
Which action must be added to the pipeline, after the application is deployed in the staging environment to minimize failures and to ensure a successful continuous deployment?

Functional and nonfunctional tests must be run before it is promoted to production

Functional and nonfunctional tests must be run after it is promoted to production

Restructuring and monitoring tests must be run after it is promoted to production

Restructuring and monitoring tests must be run before it is promoted to production

Explanation
According to Cisco’s Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, it is important to run functional and non-functional tests before promoting the application to production. This is essential in order to identify and address any issues that could cause code-based failures.
Additionally, a pipeline should include automated tests that can be used to verify that processes are running correctly. By running these tests before promoting to production, you can ensure that any potential issues are identified and addressed before the application is released.

A developer wants to deploy a highly available web server cluster and decides to put a load balancer in front of multiple clustered nodes that run the same web service. The goal is for the load balancer to take in users and distribute the load across the whole cluster.
What kind of high-availability configuration is the developer running?

active

passive

active-passive

active-active

An active-active high-availability configuration is when the load balancer is used to distribute the load across the whole cluster of nodes that are running the same web service. In this configuration, all of the nodes are active and available to serve requests at any given time. This is in contrast to an active-passive configuration, where only one node is active and the other nodes are passive and serve as backups in case of a failure.
