A developer runs the docker service scale command to increase the number of replicas for the cisco_devnet service. The swarm cluster is using a private IP address subnet.
The service has these design requirements:
✑ It must be hosted behind a virtual IP address that is reachable from the Internet.
✑ For security reasons, the Docker swarm cluster subnet must not be reachable from the Internet.
Which design approach is used to fulfill the requirements?
- A . Create an overlay network by using a globally roulable subnet and enable a routing mesh within the swarm cluster.
- B . Create a bridge network by using a globally routable subnet and enable a routing mesh within the swarm cluster.
- C . Configure an external load balancer to route requests to the swarm service by using VPN.
- D . Configure an external load balancer to route requests to the swarm service by using NAT.
A developer deploys a SQLite database in a Docker container. Single-use secret keys are generated each time a user accesses the database. The keys expire after 24 hours.
Where should the keys be stored?
- A . Outside of the Docker container in the source code of applications that connect to the SQLite database.
- B . In a separate file inside the Docker container that runs the SQLite database.
- C . In an encrypted database table within the SQLite database.
- D . In a separate storage volume within the Docker container.
