💡 Hint

Common Mistakes

Using --disable-setup-wizard disables the wizard, which is not what we want.

Using httpPort=8080 sets the port but does not affect the wizard.

Using --version only shows the version and exits.

The --enable-setup-wizard option starts Jenkins with the initial admin setup wizard enabled.

💡 Hint

Common Mistakes

Trying to read the config.xml file instead of the password file.

Looking in the wrong directory for the password.

Reading the Jenkins log file instead of the password.

The initial admin password is stored in /var/lib/jenkins/secrets/initialAdminPassword. Reading this file lets you unlock Jenkins during setup.

Using underscores instead of hyphens.

Using camelCase instead of hyphen-separated words.

Missing hyphen between 'setup' and 'wizard'.

Complete the code to create a dictionary comprehension that maps plugin names to their versions, filtering only plugins with version greater than 1.0.

Jenkins

{plugin: version for plugin, version in plugins.items() if version [1] '1.0'}

Drag options to blanks, or click blank then click option'

D==

💡 Hint

Common Mistakes

Putting an operator in BLANK_1 which breaks the syntax.

Using < or == instead of > for filtering versions.

The dictionary comprehension maps each plugin to its version without modification (empty string for BLANK_1). The filter keeps plugins with version greater than '1.0' using >.

Fill all three blanks to create a dictionary comprehension that maps plugin names in uppercase to their versions, filtering only plugins with version equal to '2.0'.

Jenkins

{ [1]: [2] for plugin, version in plugins.items() if version [3] '2.0' }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the plugin name without uppercasing.

Using wrong comparison operators like < or >.

Swapping key and value positions.

The dictionary comprehension uses plugin.upper() as the key, version as the value, and filters plugins where version == '2.0'.
