PCD Integrating Google Cloud services Practice Question
This PCD practice question tests your understanding of integrating google cloud services. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company stores sensitive user data in Cloud Storage. They want to ensure that only authenticated users with the appropriate permissions can access the data, and that data is encrypted at rest. Which two steps should they take? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable default encryption on the bucket using Google-managed keys.
Option B is correct because Cloud Storage buckets are encrypted at rest by default using Google-managed keys, which satisfies the requirement for data encryption without additional configuration. Option C is correct because IAM roles provide fine-grained access control, ensuring only authenticated users with appropriate permissions can access the data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configure a Customer-Managed Encryption Key (CMEK) in Cloud KMS.
Why it's wrong here
CMEK is optional, not required.
✓
Enable default encryption on the bucket using Google-managed keys.
Why this is correct
Default server-side encryption is already enabled.

✓
Use IAM roles to grant access to specific users and groups.
Why this is correct
IAM controls access.

✗
Set bucket-level public access prevention.
Why it's wrong here
This prevents public access, not encryption.
✗
Enable VPC Service Controls to restrict data access.
Why it's wrong here
VPC SC is for perimeter security, not encryption.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that enabling default encryption or using CMEK is optional or that public access prevention alone satisfies access control, when in fact IAM is the primary mechanism for user-level authorization and default encryption is already enabled.
Detailed technical explanation
How to think about this question
Cloud Storage uses server-side encryption by default with Google-managed keys (AES-256) for all objects at rest, which is transparent to users and requires no bucket configuration. IAM roles such as roles/storage.objectViewer or roles/storage.objectAdmin are evaluated at request time, and access is denied unless the principal has an explicit binding; this is distinct from ACLs, which are legacy and less granular. In a real-world scenario, combining default encryption with IAM ensures that even if a bucket is accidentally made public, objects remain encrypted, but IAM still blocks unauthenticated access.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
