NEW QUESTION # 110
Will this command ensure that overlay traffic between service tasks is encrypted?
Solution.docker network create -d overlay --secure <network-name>
Answer: B
Explanation:
Explanation
= The command docker network create -d overlay --secure <network-name> will not ensure that overlay traffic between service tasks is encrypted. The --secure option is not a valid flag for the docker network create command1. To enable encryption for an overlay network, you need to use the --opt encrypted flag instead23. This will create IPSEC tunnels between the nodes where the service tasks are scheduled, using the AES algorithm in GCM mode2. You can verify if an overlay network is encrypted by checking if the IPSEC tunnels were created using tools like netstat4. References:

NEW QUESTION # 113
Will this configuration achieve fault tolerance for managers in a swarm?
Solution: only two managers, one active and one passive.
Answer: B
Explanation:
Explanation
= The configuration will not achieve fault tolerance for managers in a swarm, because it does not have enough managers to form a quorum. A quorum is the minimum number of managers that must be available to agree on values and maintain the consistent state of the swarm. The quorum is calculated as (N/2)+1, where N is the number of managers in the swarm. For example, a swarm with 3 managers has a quorum of 2, and a swarm with 5 managers has a quorum of 3. Having only two managers, one active and one passive, means that the quorum is also 2. Therefore, if one manager fails or becomes unavailable, the swarm will lose the quorum and will not be able to process any requests or schedule any tasks. To achieve fault tolerance, a swarm should have an odd number of managers, at least 3, and no more than 7. This way, the swarm can tolerate the loss of up to (N-1)/2 managers and still maintain the quorum and the cluster state. References:
