Which type of node will never store data or perform any type of analysis?

Question

Options

• AData node
• BPrimary Replica node
• CPrimary node
• DRemote Collector node

• A
  3% (1)
• B
  8% (3)
• C
  3% (1)
• D
  87% (33)

Explanation

Remote Collector nodes act purely as passive forwarding agents - they gather raw data from sources in their network segment and transmit it upstream to processing nodes, but they never store that data locally or run any analysis on it. This "collect and forward only" design is intentional, allowing deployment in remote or resource-constrained locations without the overhead of storage or compute.

• A (Data node) is wrong because, by definition, its entire purpose is to store data.
• B (Primary Replica node) is wrong because replica nodes maintain copies of data for redundancy - storage is their core function.
• C (Primary node) is wrong because primary nodes coordinate cluster operations and perform analysis/processing tasks.

Memory tip: Think of the Remote Collector as a mail carrier - it picks up packages (data) and delivers them, but it never reads the contents or keeps copies. The word "Remote" is also a hint: nodes deployed far from the core infrastructure are typically lightweight by necessity, doing the minimum work (collecting) and nothing more.
