Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Use the --cluster.peer flag
High Availability (HA) for Alertmanager is achieved by running multiple instances and using the '--cluster.peer' flag to link them.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable grouping
Why it's wrong here
Disabling grouping would make alert management harder, not improve availability.
- ✗
Set repeat_interval to 0
Why it's wrong here
This would cause infinite spam, not HA.
- ✗
Use a load balancer only
Why it's wrong here
A load balancer alone doesn't handle the internal state sharing required for deduplication.
- ✓
Use the --cluster.peer flag
Why this is correct
Clustering ensures Alertmanager instances share state and suppress duplicate notifications.
