What is the messaging server component for 400 agent deployments?

Question

Options

• Acollocated with other components and with services server
• Balways installed on a dedicated VM
• Ccollocated only with services server
• Dcollocated with other components

• A
  2% (1)
• B
  2% (1)
• C
  5% (2)
• D
  91% (40)

Explanation

For 400-agent deployments, the messaging server follows a collocated topology - sharing infrastructure with other components rather than requiring its own dedicated VM. This mid-scale deployment size doesn't yet demand the resource isolation of a fully distributed architecture, so collocating components is both practical and supported.

Why the distractors are wrong:

• A is incorrect because it includes colocation with the services server, which is a separate placement decision - at 400 agents, the messaging server does not share a host with the services server.
• B is incorrect because a dedicated VM for the messaging server is reserved for larger, high-demand deployments where resource contention becomes a concern.
• C is a partial truth trap - colocation with only the services server contradicts the correct topology and misrepresents where the messaging server actually lives.

Memory tip: Think of deployment scale as a spectrum - small deployments colocate everything, large deployments isolate everything, and mid-scale (like 400 agents) colocates most components but keeps the services server separate. "D for Distributed-but-not-yet" helps anchor that 400 agents = shared but not fully split.
