The most popular DevOps tools include:

• 1. Selenium
• 2. Puppet
• 3. Chef
• 4. Git
• 5. Jenkins

The core benefits of DevOps are as follows:

• Technical benefits
• ● Continuous software delivery
• ● Less complex problems to manage
• ● Early detection and faster correction of defects
• Business benefits

Continuous monitoring in DevOps is a process of detecting, identifying, and reporting any faults or threats in the entire infrastructure of the system.

• ● Ensures that all services, applications, and resources are running on the servers properly.
• ● Monitors the status of servers and determines if applications are working correctly or not.
• ● Enables continuous audit, transaction inspection, and controlled monitoring.

The three important KPIs are as follows:

• ● Meantime to failure recovery - This is the average time taken to recover from a failure.
• ● Deployment frequency - The frequency in which the deployment occurs.
• ● Percentage of failed deployments - The number of times the deployment fails.

Start by talking about the age-old mechanisms of writing commands onto script files and testing them in a separate environment before deployment and how this approach is being replaced by IaC. Similar to the codes written for other services, with the help of AWS, IaC allows developers to write, test, and maintain infrastructure entities in a descriptive manner, using formats such as JSON or YAML. This enables easier development and faster deployment of infrastructure changes.

• ● Enables management of and changes to multiple systems.
• ● Standardizes resource configurations, which in turn, manage IT infrastructure.
• ● It helps with the administration and management of multiple servers and maintains the integrity of the entire infrastructure.

• 1. git rm
• 2. git mv
• 3. git rm -r
• 4. None of the above

The correct answer is B) git mv

Suppose you are working on an application, and you want to add a new feature to the app. You can create a new branch and build the new feature on that branch.

• ● By default, you always work on the master branch
• ● The circles on the branch represent various commits made on the branch
• ● After you are done with all the changes, you can merge it with the master branch

The command to get a list of files that have been changed in a particular commit is:

git diff-tree –r {commit hash}

Example: git diff-tree –r 87e673f21b

• ● -r flag instructs the command to list individual files
• ● commit hash will list all the files that were changed or added in that commit

• ● Jenkins master pulls the code from the remote GitHub repository every time there is a code commit.
• ● It distributes the workload to all the Jenkins slaves.
• ● On request from the Jenkins master, the slaves carry out, builds, test, and produce test reports.

• 1. java –jar Jenkins.war
• 2. java –war Jenkins.jar
• 3. java –jar Jenkins.jar
• 4. java –war Jenkins.war

The correct answer is A) java –jar Jenkins.war

• 1. build.xml
• 2. pom.xml
• 3. dependency.xml
• 4. Version.xml

The correct answer is B) pom.xml

• ● Jenkins uses an internal database to store user data and credentials.
• ● Jenkins can use the Lightweight Directory Access Protocol (LDAP) server to authenticate users.
• ● Jenkins can be configured to employ the authentication mechanism that the deployed application server uses.

• ● When security is enabled, the Config file contains an XML element named useSecurity that will be set to true.
• ● By changing this setting to false, security will be disabled the next time Jenkins is restarted.

Two ways to manually restart Jenkins:

• 1. (Jenkins_url)/restart // Forces a restart without waiting for builds to complete
• 1. (Jenkins_url)/safeRestart // Allows all running builds to complete before it restarts

Exceptions are events that occur during the execution of a program and disrupt the normal flow of a program's instructions. Selenium has the following exceptions:

• ● TimeoutException - It is thrown when a command performing an operation does not complete in the stipulated time.
• ● NoSuchElementException - It is thrown when an element with specific attributes is not found on the web page.
• ● ElementNotVisibleException - It is thrown when an element is present in Document Object Model (DOM) but is not visible. Ex: Hidden Elements defined in HTML using type=“hidden”.
• ● SessionNotFoundException - The WebDriver is performing the action immediately after quitting the browser.

These are two different methods used to close the browser session in Selenium WebDriver:

• ● driver.close() - This is used to close the current browser window on which the focus is set. In this case, there is only one browser open.● driver.quit() - It closes all the browser windows and ends the WebDriver session using the driver.dispose method.

Test Kitchen is a command-line tool in Chef that spins up an instance and tests the cookbook on it before deploying it on the actual nodes.

• ● Changes in the configuration are tracked using Jira, and further maintenance is done through internal procedures.
• ● Version control takes the support of Git and Puppet's code manager app.
• ● The changes are also passed through Jenkin's continuous integration pipeline.
