A company needs to deploy a machine learning model in a cost-effective manner. What is the best approach?
AUse Google Cloud Run
BUse Google Compute Engine
CUse Google Kubernetes Engine
DUse Google App Engine
Explanation
Google Cloud Run efficiently serves models in a serverless manner; others may incur higher operational costs.
Q312
What happens when a Google Cloud Storage bucket is deleted?
AData is permanently deleted.
BData is archived for recovery.
CBucket is temporarily disabled.
DData is replicated elsewhere.
Explanation
Data in a deleted bucket is permanently gone; others suggest non-existent recovery options.
Q313
Which Google Cloud service is best for managing serverless APIs?
ACloud Run
BCloud Functions
CApp Engine
DCompute Engine
Explanation
Cloud Functions is specifically designed for serverless event-driven architecture, while Cloud Run and App Engine can also serve APIs but with more overhead.
Q314
You are configuring access for BigQuery datasets. What role provides complete access?
ABigQuery Data Editor
BBigQuery Job User
CBigQuery Admin
DBigQuery Data Viewer
Explanation
The BigQuery Admin role grants all permissions, including full access to datasets, while other roles have limited permissions.
Q315
A machine learning model in Vertex AI has a decreased accuracy. What can you do first?
AReview deployment logs
BIncrease the training dataset
CRe-train the model immediately
DAnalyze feature importance
Explanation
Analyzing feature importance can reveal if relevant features are missing or affecting accuracy, guiding informed adjustments, whereas the other options may not identify the root cause.
Q316
Which Google Cloud service is ideal for building machine learning models using big data?
ABigQuery
BCloud Functions
CCloud Pub/Sub
DCloud Run
Explanation
BigQuery is optimized for data analysis and ML model training, while others target different functions.
Q317
A company needs to manage user access to services based on their job role. Which feature should they implement?
ACloud Identity
BService Accounts
CIAM Roles
DVPC Peering
Explanation
IAM Roles provide fine-grained access control, unlike the other options.
Q318
What happens when you enable AutoML on a dataset without enough labeled examples?
ATraining will succeed with lower accuracy.
BTraining will fail with a bad model.
CAutoML will estimate labels automatically.
DTraining will succeed but be limited.
Explanation
AutoML can train with limited data but results may be suboptimal.
Q319
Which Google Cloud service is designed specifically for building and managing machine learning models?
ACloud ML Engine
BBigQuery
CCompute Engine
DCloud Functions
Explanation
Cloud ML Engine is tailored for machine learning tasks, while others focus on data processing or compute resources.
Q320
A company needs to ensure that only specific users can access certain datasets in BigQuery. What would be the most effective way to implement this?
AIAM roles at the project level
BTable-level access controls
CQuery permissions only
DAPI key restrictions
Explanation
Table-level access controls provide granular permissions specific to datasets, unlike project-level roles.
