Google PCA Practice Question: Analysing and Optimising Technical and Business Processes
A company is moving a legacy application to Compute Engine. The application has inconsistent resource usage and the team wants to optimise costs without performance degradation. They are evaluating committed use discounts (CUDs) and other discount types. Which THREE statements are correct about CUDs? (Choose 3)
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
✓
Spend-based CUDs are applied automatically to all eligible projects in the billing account
CUDs offer discounts for 1-year or 3-year commitments. Resource-based CUDs apply to specific machine types in a region. Spend-based CUDs apply to total compute spend. CUDs can be combined with sustained use discounts, but sustained use discounts are automatic and not required to be purchased.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
CUDs require a minimum of 10 instances to qualify
Why it's wrong here
There is no minimum instance count; CUDs are per vCPU or per spend.
- ✓
Spend-based CUDs are applied automatically to all eligible projects in the billing account
Why this is correct
Spend-based CUDs apply at the billing account level.
- ✗
CUDs cannot be combined with sustained use discounts
Why it's wrong here
They can be combined; sustained use discounts apply automatically and are additive.
- ✓
CUDs provide a discount in exchange for committing to a minimum spend or resource usage for 1 or 3 years
Why this is correct
That is the definition of CUDs.
- ✓
Resource-based CUDs apply to a specific machine series and region
Why this is correct
Resource-based CUDs are tied to specific machine families and regions.
