B . No

View Answer

Answer: B

Explanation:

: = The command docker service create –network –secure will not ensure that overlay traffic between service tasks is encrypted. This is because the –secure option is not a valid option for the docker service create command1. To ensure that overlay traffic between service tasks is encrypted, you need to use the –opt encrypted option when creating the overlay network with the docker network create command2. For example, to create an encrypted overlay network named my-net, you can use the following command:

docker network create –driver overlay –opt encrypted my-net

Then, you can use the –network my-net option when creating the service with the docker service create command3. For example, to create a service named my-service using the nginx image and the my-net network, you can use the following command:

docker service create –name my-service –network my-net nginx
