Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
oc get services --cluster
Why it's wrong here
There is no --cluster flag for listing services across namespaces.
- ✓
oc get svc -A
Why this is correct
The -A flag is shorthand for --all-namespaces, displaying services cluster-wide.
- ✗
oc describe service --all
Why it's wrong here
The describe command requires specific resource names and does not accept an --all flag.
- ✗
oc adm top services
Why it's wrong here
oc adm top displays resource utilization (CPU/memory), not a list of services.
