Explanation:
An OpenShift route is a way to provision external access to a service. A route exposes a service at a host name, such as www.example.com, that external clients can use to access the service. A route can also specify security options, such as TLS termination, and load balancing options, such as round robin or least connection.
NEW QUESTION # 49
Click the Exhibit button.
Referring to the exhibit, which statement is correct?
- A. There are no projects.
- B. There are no compute nodes.
- C. There are no services.
- D. There are no virtual machines.
Answer: D
Explanation:
There are no virtual machines. Referring to the exhibit, which shows the output of the openstack server list command, we can see that there are no rows in the table, which means that there are no servers (or virtual machines) in the OpenStack environment. The command openstack server list is used to list servers that you can access. The other statements are incorrect, because the exhibit does not show any information about projects, services, or compute nodes. To list projects, you would use the command openstack project list. To list services, you would use the command openstack service list. To list compute nodes, you would use the command openstack compute service list.
