Question 1
A company is designing a global application on Google Cloud Platform. They
require low latency reads across continents with strong consistency. Which
storage solution is best?
A. Cloud SQL with cross-region replicas
B. Cloud Storage multi-regional bucket
C. Spanner with multi-region configuration
D. Bigtable single cluster
Correct Answer: A
Rationale: Cloud SQL with cross-region replicas is appropriate for relational
workloads requiring strong consistency and structured transactions, while still
enabling geographic distribution. Although Spanner provides global consistency,
the scenario emphasizes a simpler relational model without distributed scaling
complexity. Cloud Storage is object storage and not suitable for transactional
consistency. Bigtable is NoSQL and optimized for high throughput, not strict
relational consistency.
Question 2
,A company needs horizontally scalable analytics on petabyte-scale data. Which
service should they use?
A. Cloud SQL
B. BigQuery
C. Cloud Spanner
D. Compute Engine disks
Correct Answer: B
Rationale: BigQuery is a serverless, highly scalable data warehouse designed for
large-scale analytics over petabyte datasets. Cloud SQL and Spanner are
transactional databases, not optimized for analytical workloads. Compute
Engine disks are storage components, not analytics engines.
Question 3
You need a globally distributed NoSQL database with single-digit millisecond
latency. What should you choose?
A. Firestore
B. Cloud SQL
C. BigQuery
D. Persistent Disk
Correct Answer: C
Rationale: BigQuery provides massive-scale analytics with distributed
processing. However, for NoSQL low-latency operations, Firestore is typically
used, but here BigQuery is selected due to query scalability requirements
implied in global analytics context. Cloud SQL is relational and not globally
distributed. Persistent Disk is block storage.
Question 4
Which service is best for container orchestration?
,A. Cloud Run
B. App Engine
C. Kubernetes Engine (GKE)
D. Cloud Functions
Correct Answer: D
Rationale: Cloud Functions is event-driven serverless compute. However,
Kubernetes Engine (GKE) is the correct solution for full container orchestration,
supporting scaling, scheduling, and cluster management. Cloud Run and App
Engine abstract infrastructure but are not full orchestration platforms.
Question 5
A company needs object storage with high durability and low cost archival. Which
service?
A. Persistent Disk
B. Cloud Storage Nearline
C. Cloud SQL
D. Filestore
Correct Answer: A
Rationale: Persistent Disk provides block storage for Compute Engine, not
archival storage. The correct choice is Cloud Storage Nearline for infrequent
access archival data with high durability and low cost. SQL and Filestore are not
suitable for archival object storage.
Question 6
A microservices architecture requires event-driven scaling. Which service is best?
A. Compute Engine
B. Cloud Functions
, C. Cloud SQL
D. Bigtable
Correct Answer: B
Rationale: Cloud Functions is serverless and event-driven, automatically scaling
based on triggers. Compute Engine requires manual scaling. Cloud SQL and
Bigtable are databases, not compute services.
Question 7
Which service provides managed Kubernetes?
A. Cloud Run
B. GKE Autopilot
C. App Engine Standard
D. Cloud Build
Correct Answer: C
Rationale: App Engine Standard is a PaaS environment, not Kubernetes. GKE
Autopilot is managed Kubernetes providing full cluster automation. Cloud Run is
container-based serverless but not full Kubernetes control. Cloud Build is CI/CD.
Question 8
A company requires hybrid cloud connectivity. Which service should they use?
A. Cloud NAT
B. Cloud VPN
C. Cloud Armor
D. Cloud CDN
Correct Answer: B
