Google Cloud Certified MCQ 5

Question 1

A company needs to connect their on-premises data center to Google Cloud with 10 Gbps bandwidth, consistent latency, and an SLA. Which option is correct?

Accepted Answer

Dedicated Interconnect with 10 Gbps circuit

Answer

Dedicated Interconnect provides a direct physical connection to Google with a 99.99% SLA (with redundant circuits) and guaranteed bandwidth without traversing the public internet.

Question 2

An architect needs to implement a blue/green deployment for a Cloud Run service to allow instant rollback. What is the correct mechanism?

Accepted Answer

Use Cloud Run traffic splitting to route 100% traffic to the new revision, retaining the old revision

Answer

Cloud Run revision traffic splitting allows atomic traffic shifts between revisions, and rolling back simply redirects 100% traffic to the prior revision instantly.

Question 3

A healthcare application must ensure that data never leaves a specific geographic region for compliance. Which combination of controls enforces this?

Accepted Answer

Use VPC Service Controls with a perimeter and resource location restrictions via Organization Policy

Answer

VPC Service Controls restrict API access to within the perimeter, and the constraints/gcp.resourceLocations policy prevents resource creation outside approved regions.

Question 4

A team wants to use Terraform to manage Google Cloud infrastructure and prevent drift between the desired and actual state. What workflow best achieves this?

Accepted Answer

Store Terraform state in a Cloud Storage bucket, use a CI/CD pipeline to run terraform plan on PRs and terraform apply on merge

Answer

Remote state in Cloud Storage with CI/CD-enforced plan-then-apply workflow ensures state is shared, changes are reviewed, and applies are auditable.

Question 5

Your BigQuery costs are high due to analysts running full table scans on a large table frequently queried by date. What is the most cost-effective optimization?

Accepted Answer

Partition the table by date and require analysts to include the partition filter in queries

Answer

Date partitioning restricts bytes scanned to only relevant partitions when a date filter is applied, directly reducing per-query cost.
