Practice

1. What is the main purpose of configuring dashboard views in Jenkins?

easy

A. To organize jobs for easy monitoring

B. To write build scripts

C. To deploy applications automatically

D. To manage user permissions

Solution

1. Step 1: Understand dashboard views role

   Dashboard views help group and display jobs clearly.

2. Step 2: Identify main benefit

   This organization makes monitoring easier for users.

3. Final Answer:

   To organize jobs for easy monitoring -> Option A

4. Quick Check:

   Dashboard views = organize jobs [OK]

Hint: Dashboard views group jobs visually for monitoring [OK]

Common Mistakes:

• Confusing dashboard views with build scripts
• Thinking views manage permissions
• Assuming views deploy apps automatically

2. Which syntax correctly filters jobs by name pattern in a Jenkins dashboard view?

easy

A. test*

B. test$

C. test?

D. .*test.*

Solution

1. Step 1: Recognize regex pattern for filtering

   Jenkins uses regular expressions to filter job names.

2. Step 2: Identify correct regex for 'test' anywhere

   .*test.* matches any job name containing 'test'.

3. Final Answer:

   .*test.* -> Option D

4. Quick Check:

   Regex pattern for contains 'test' = .*test.* [OK]

Hint: Use .*pattern.* to match substring in job names [OK]

Common Mistakes:

• Using wildcard * without dot in regex
• Confusing ? with * in regex
• Using end anchor $ incorrectly

3. Given a dashboard view configured to show columns: Job Name, Last Success, and Build Duration, what will be displayed?

medium

A. Job names, last successful build time, and how long builds took

B. Only job names and their last successful build time

C. Job names and build status only

D. Build duration and job description only

Solution

1. Step 1: Analyze configured columns

   The columns are Job Name, Last Success, and Build Duration.

2. Step 2: Understand what each column shows

   Job Name shows job titles, Last Success shows last successful build time, Build Duration shows how long builds took.

3. Final Answer:

   Job names, last successful build time, and how long builds took -> Option A

4. Quick Check:

   Columns = Job Name + Last Success + Build Duration [OK]

Hint: Columns show exactly the info you select in view config [OK]

Common Mistakes:

• Ignoring Build Duration column
• Assuming build status is shown without selecting
• Confusing Last Success with build status

4. You configured a dashboard view to filter jobs with pattern build.* but no jobs appear. What is the likely error?

medium

A. Dashboard views do not support regex filtering

B. The pattern should be build* without dot

C. The pattern is case-sensitive and jobs start with uppercase 'Build'

D. You must restart Jenkins after changing views

Solution

1. Step 1: Check regex pattern and job names

   The pattern build.* matches lowercase 'build' at start.

2. Step 2: Consider case sensitivity

   Jenkins regex is case-sensitive by default; jobs starting with 'Build' (uppercase) won't match.

3. Final Answer:

   The pattern is case-sensitive and jobs start with uppercase 'Build' -> Option C

4. Quick Check:

   Regex case sensitivity causes no matches [OK]

Hint: Regex is case-sensitive; match exact case or use (?i) [OK]

Common Mistakes:

• Removing dot from regex incorrectly
• Believing Jenkins needs restart for view changes
• Thinking regex filtering is unsupported

5. You want a dashboard view that shows only jobs with names containing 'deploy' or 'release' and displays columns: Job Name, Last Build Status, and Duration. Which configuration achieves this?

hard

A. Use regex deploy|release and select columns Job Name, Last Success, Build Duration

B. Use regex .*(deploy|release).* and select columns Job Name, Last Build Status, Duration

C. Use regex deploy.*release and select columns Job Name, Last Build Status, Duration

D. Use regex deploy|release and select columns Job Name, Last Build, Duration

Solution

1. Step 1: Create regex for 'deploy' or 'release'

   The regex .*(deploy|release).* matches job names containing either word anywhere.

2. Step 2: Select correct columns

   Columns needed are Job Name, Last Build Status, and Duration exactly as named.

3. Final Answer:

   Use regex .*(deploy|release).* and select columns Job Name, Last Build Status, Duration -> Option B

4. Quick Check:

   Regex with (deploy|release) and correct columns [OK]

Hint: Use (a|b) in regex for OR conditions [OK]

Common Mistakes:

• Using regex without .* to match anywhere
• Selecting wrong column names
• Assuming simple 'deploy|release' matches anywhere
