1Z0-1072-26 Compute Practice Question
You are troubleshooting a performance issue on an OCI compute instance. You suspect that the instance is experiencing CPU throttling due to credits being exhausted. Which compute shape type are you most likely using?
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
✓
Standard AMD Flexible Shape with baseline OCPU performance enabled
Burstable instances (such as VM.Standard.E3.Flex or VM.Standard.E4.Flex configured with baseline OCPU utilization or specific micro/standard burstable settings) use CPU credits. If credits are exhausted, performance is throttled to the baseline.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
HPC (High-Performance Computing) Shape
Why it's wrong here
HPC shapes are optimized for tightly coupled MPI workloads with dedicated cores, not burstable CPU credits.
- ✓
Standard AMD Flexible Shape with baseline OCPU performance enabled
Why this is correct
Burstable instances use CPU credits to allow temporary bursting above baseline, which can lead to throttling if credits run out.
- ✗
Bare Metal Standard Shape
Why it's wrong here
Bare metal shapes dedicate the entire physical hardware and do not use burstable CPU credits.
- ✗
GPU Shape
Why it's wrong here
GPU shapes are designed for graphics and parallel compute acceleration without burstable credit limits.
