EX294 Practice Test 8 — 10 Questions

Question 1

An Ansible playbook includes multiple roles. The administrator wants to ensure that a specific role's tasks are executed before any other roles, even if the roles are listed in a different order in the playbook. Which approach should be used?

Accepted Answer

Use the 'pre_tasks' section in the playbook to call the role.. Option B is correct because pre_tasks run before any roles, ensuring ordering. Option A (any_errors_fatal) is for error handling, not ordering. Option C (role dependencies) can enforce order but not as straightforward as pre_tasks. Option D is not a valid parameter.

Answer

Use the 'any_errors_fatal' setting.

Answer

Use role dependencies with 'allow_duplicates: no'.

Answer

Set the 'order' parameter in the role definition.

Question 2

An administrator is debugging a playbook that uses multiple roles and wants to limit execution to a specific set of tasks. Which three methods can be used to filter task execution? (Choose three.)

Accepted Answer

Use the '--tags' command-line option.. Options A, B, and C are correct. Option D (--step) prompts after each task but doesn't filter. Option E (--check) performs a dry run without filtering.

Answer

Use the '--check' command-line option.

Answer

Use the '--step' command-line option.

Question 3

A developer wants to reuse a set of tasks that conditionally include other task files based on variables defined per host. Which method should be used to ensure the included tasks are evaluated per host at runtime?

Accepted Answer

include_tasks. Option C (include_tasks) is correct because it is dynamic and evaluated per host at runtime. Option A (import_tasks) is static and evaluated at parse time. Options B and D are also static imports for roles.

Answer

include_role

Answer

import_role

Answer

import_tasks

Question 4

An Ansible playbook uses the 'block' and 'rescue' directives. Which two statements are true about this construct? (Choose two.)

Accepted Answer

A rescue section executes only if the block tasks fail.. Options A and C are correct. Option B is false because only one rescue section per block is allowed. Option D is false because rescue runs only on hosts where the block failed. Option E is false because blocks can be nested.

Answer

Rescue tasks are executed on all hosts in the play.

Answer

Blocks cannot be nested.

Answer

A block can have multiple rescue sections.

Question 5

A playbook uses ansible.builtin.import_playbook to include other playbooks. The administrator needs to pass variables to the imported playbook. Which approach is valid?

Accepted Answer

Add a 'vars' block to the import_playbook statement. When using import_playbook, variables can be passed using the 'vars' keyword within the import statement. This makes the variables available throughout the imported playbook.

Answer

Use ansible.builtin.include_vars inside the imported playbook

Answer

Set variables using set_fact before the import

Answer

Use group_vars or host_vars

Question 6

In an Ansible playbook, the 'strategy' parameter is set to 'free'. What behavior does this strategy produce?

Accepted Answer

Each host runs through the playbook independently of other hosts.. Option A is correct. The 'free' strategy allows each host to run through the playbook independently without waiting for other hosts. Option B (linear) is the default where hosts wait at each task. Option C (serial) batches hosts. Option D is not a valid strategy.

Answer

Playbook runs tasks on hosts in batches of 1.

Answer

Strategy is deprecated and replaced by 'linear'.

Answer

All hosts run the same task at the same time, then move to the next task.

Question 7

Refer to the exhibit. The playbook fails with an error. What is the most likely cause?

Accepted Answer

import_tasks cannot be used with a loop.. Option A is correct. import_tasks is static and cannot be used with a loop; include_tasks should be used for dynamic inclusion.

Answer

import_tasks must be placed in a role.

Answer

The loop variable should be referenced as '{{ item }}' without quotes.

Answer

The file names must be literal without templates.

Question 8

A playbook uses roles with default variables. The administrator needs to override a default variable for a specific role only when that role is used. Which method should be used?

Accepted Answer

Pass the variable as a parameter to the role in the playbook.. Option D (role parameters) is correct because they are passed directly to the role in the playbook and override defaults. Option A (role vars) have higher priority but are static. Option B (playbook vars) apply to all roles. Option C (inventory vars) apply to all hosts/roles.

Answer

Set the variable in the inventory host_vars.

Answer

Set the variable in the role's vars/main.yml.

Answer

Set the variable in the playbook's vars section.

Question 9

Refer to the exhibit. The administrator observes the output and is concerned because the 'Check on async job' task shows 'finished: 0'. What does this indicate?

Accepted Answer

The async job is still running.. Option B is correct. finished: 0 means the job is still running. finished: 1 would indicate completion.

Answer

The async job was not started.

Answer

The async job failed.

Answer

The async job has completed successfully.

Question 10

An Ansible playbook fails intermittently due to a service not starting in time. The administrator wants to configure a task to retry until the service confirms it is running. Which Ansible feature should be used?

Accepted Answer

Until loop with retries and delay.. Option D (until loop with retries and delay) is correct. Option A (failed_when) only sets failure conditions, not retries. Option B (block/rescue) handles errors but doesn't retry. Option C (async) starts a task and polls later but doesn't inherently retry on failure.

Answer

Failed_when with conditional retry.

Answer

Block and rescue to catch failure.

Answer

Async with poll interval.
