ISC2 CC Practice Question: A security operations team is implementing a new…
A security operations team is implementing a new SIEM solution. They want to ensure that logs from all critical systems are collected and analyzed in real time. Which of the following is the MOST important consideration when designing the log collection architecture?
⚠ Common exam trap
ISC2 often tests the distinction between operational feasibility (bandwidth/storage) and security or compliance features, leading candidates to over-prioritize encryption or retention policies when the core requirement is real-time ingestion.

Correct answer & explanation
✓
Ensure sufficient network bandwidth and storage capacity
The most critical factor in real-time log collection is ensuring that the network can handle the volume of log data without congestion and that storage can ingest and retain the data without dropping events. Without sufficient bandwidth, logs will be delayed or lost, defeating the purpose of real-time analysis. Storage capacity directly impacts the ability to retain and query logs for immediate and historical investigation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Ensure sufficient network bandwidth and storage capacity
Why this is correct
Insufficient bandwidth can cause log loss, and inadequate storage can lead to data being overwritten before analysis.
- ✗
Use a standardized log format for all systems
Why it's wrong here
Standardization helps parsing but is not as critical as ensuring the logs can be collected reliably.
- ✗
Encrypt all log transmissions in transit
Why it's wrong here
Encryption is a security requirement but does not affect the ability to collect logs.
- ✗
Define a log retention policy of at least one year
Why it's wrong here
Retention policy is for storage, not for the collection architecture itself.
