XSIAM-Engineer Planning And Installation Practice Question
An architect is estimating storage capacity requirements for Cortex XSIAM. Which formula correctly represents the core calculation for raw daily log ingestion planning?
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.
Correct answer & explanation
✓
Average daily log volume (GB/day) multiplied by retention period (days), adjusted for indexing and replication multipliers
Daily storage sizing is calculated by multiplying the average daily event count by the average event size, accounting for compression and parsing factors.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Number of active user accounts multiplied by active session duration
Why it's wrong here
User session duration is unrelated to log lake data volume sizing.
- ✗
Number of endpoints multiplied by total RAM capacity
Why it's wrong here
RAM capacity does not determine storage sizing for log lakes.
- ✗
Total CPU cores on Broker VMs divided by network latency
Why it's wrong here
CPU cores and latency affect performance and throughput, not storage capacity sizing.
- ✓
Average daily log volume (GB/day) multiplied by retention period (days), adjusted for indexing and replication multipliers
Why this is correct
Total storage equals daily ingestion multiplied by retention days, factored by indexing and replication overhead.
