Why Practice for the Docker Certified Associate?

Docker Certified Associate tests applied decisions across orchestration, image creation and registries, installation and configuration, networking, security, and storage. The bank follows the relative weighting of the public blueprint rather than distributing questions evenly.

Every item uses four distinct options and one best answer. Automated structure and semantic-duplicate checks are followed by independent content review and targeted repair.

Use these questions alongside the current official Docker exam guide and product documentation. Product behavior changes, so verify details in the linked official sources as you study.

Sample Practice Questions

Try each question before revealing the answer.

Question 1

A swarm has five manager nodes. How many managers can fail before the swarm loses quorum?

AOne

BTwo

CThree

DFour

Show answer

Answer: B

Raft needs a majority of managers. With five managers the majority is three, so the swarm tolerates the loss of two.

Question 2

Which docker service create option runs exactly one task of the service on every node in the swarm?

A--replicas 0

B--mode global

C--publish mode=host

D--constraint node.role==worker

Show answer

Answer: B

A global service runs one task on every node that meets its placement constraints. A replicated service runs the number of tasks you set with --replicas.

Question 3

In docker run -p 8080:80 nginx, what does the value 8080:80 mean?

AContainer port 8080 maps to host port 80

BHost port 8080 maps to container port 80

CThe container may use ports 80 through 8080

DThe image listens on both ports

Show answer

Answer: B

The publish flag takes host port first, then container port. Traffic that reaches port 8080 on the host goes to port 80 in the container.

Frequently Asked Questions

Are these actual Docker exam questions?+

No. They are original independent practice scenarios derived from public objectives and official product documentation, not dumps or recalled exam content.

How is the 327-question bank checked?+

Questions must pass the application schema, exact and semantic duplicate checks, live official-source checks, and independent content review before promotion.

Does the bank match domain weighting?+

Yes. Integer question allocations preserve the public blueprint proportions, including normalization when a vendor publishes rounded percentages that do not sum to exactly 100%.

Can the official blueprint change?+

Yes. Certification vendors update guides and product terminology, so always compare preparation material with the current official guide.
