Agility

Answer

Scalability

Question 2

A financial services company must comply with strict data residency regulations. They want to run sensitive workloads on-premises while using Google Cloud for burst analytics. Which deployment model should they choose?

Accepted Answer

Hybrid cloud. Hybrid cloud connects on-premises infrastructure with public cloud, allowing the company to keep sensitive data on-premises while leveraging cloud analytics.

Answer

Public cloud

Answer

Private cloud

Answer

Multi-cloud

Question 3

A retail company migrated its e-commerce platform to Google Cloud. During a flash sale, the application experiences high latency. The architecture uses managed instance groups with autoscaling based on CPU utilization. The database is Cloud SQL with read replicas. What is the MOST likely cause of the latency?

Accepted Answer

Cloud SQL connection limit is reached. Database connection pooling is often misconfigured during autoscaling, leading to connection exhaustion and increased latency.

Answer

Autoscaling is not triggered because CPU utilization is below threshold

Answer

Insufficient Cloud SQL storage capacity

Answer

SSL/TLS encryption is causing overhead

Question 4

An organization wants to reduce its carbon footprint by using Google Cloud. Which of the following statements about Google Cloud's sustainability efforts is correct?

Accepted Answer

Google Cloud matches 100% of its global electricity consumption with renewable energy.. Google Cloud matches 100% of its global electricity consumption with renewable energy and aims for 24/7 carbon-free energy by 2030.

Answer

Google Cloud uses nuclear energy as its primary power source.

Answer

Google Cloud data centers are powered by 100% carbon-free energy since 2020.

Answer

Google Cloud purchases carbon offsets to neutralize all emissions.

Question 5

A company wants to run containerized applications on Google Cloud without managing the underlying infrastructure. Which service should they use?

Accepted Answer

Cloud Run. Google Kubernetes Engine (GKE) is the managed Kubernetes service that abstracts node management, but it still requires some cluster management. Cloud Run is serverless and fully manages infrastructure, so it is the best choice for zero infrastructure management.

Answer

App Engine Flexible Environment

Answer

Compute Engine

Answer

Google Kubernetes Engine (GKE)

Question 6

A media company stores video files on-premises and wants to migrate them to Google Cloud for processing and transcoding. The files are accessed by a legacy on-premises application that cannot be modified. Which migration strategy should they use?

Accepted Answer

Use Storage Transfer Service to move data to Cloud Storage, then mount the bucket using Cloud Storage FUSE on the on-premises server.. Storage Transfer Service allows transferring data from on-premises to Cloud Storage, while using Cloud Storage FUSE or a VPN can keep the on-premises application accessing the files. The best approach is to use Storage Transfer Service for bulk migration and then configure hybrid access.

Answer

Use Transfer Appliance to ship data to Google Cloud and set up a VPN for the application to access Cloud Storage via private IP.

Answer

Migrate the application to run on Compute Engine and access Cloud Storage natively.

Answer

Use gsutil rsync to copy files to Cloud Storage and update the application to use Cloud Storage URLs.

Question 7

A company is evaluating total cost of ownership (TCO) for moving its on-premises data center to Google Cloud. Which of the following costs should they include in the cloud TCO assessment?

Accepted Answer

Compute and storage usage fees. Cloud costs include compute, storage, network egress, and managed service fees. On-premises costs like hardware, power, and cooling are avoided, so they are not part of cloud TCO.

Answer

Data center facility rent and power

Answer

Hardware purchase and maintenance costs

Answer

Employee salaries for data center staff

Question 8

A developer needs to add machine learning capabilities to their application without training models from scratch. Which Google Cloud service provides pre-trained models via API?

Accepted Answer

Cloud Vision API. Cloud Vision API offers pre-trained models for image analysis accessible via API, allowing developers to integrate ML without training.

Answer

Vertex AI

Answer

AI Platform Training

Answer

Cloud AutoML

Question 9

A company uses multiple public clouds (AWS, Azure, Google Cloud) for different workloads. They want to centralize monitoring and logging. Which Google Cloud service can aggregate logs from all clouds?

Accepted Answer

Cloud Logging. Cloud Logging (formerly Stackdriver) can aggregate logs from various sources, including other clouds, using agents or API ingestion.

Answer

Cloud Audit Logs

Answer

Cloud Console

Answer

Cloud Monitoring

Question 10

A gaming company uses Google Cloud to run a multiplayer game. They use Compute Engine VMs with GPUs for game servers. During peak hours, latency increases. They want to automatically add more game server instances based on the number of concurrent players. Which scaling approach should they use?

Accepted Answer

Create a managed instance group with autoscaling based on a custom metric representing concurrent players.. Utilizing a custom metric (number of concurrent players) with managed instance groups and autoscaling is the best approach. Cloud Load Balancing distributes traffic but does not scale based on custom metrics.

Answer

Use Cloud Load Balancing to distribute traffic and add more VM instances manually.

Answer

Use Cloud Functions to spin up new game server VMs when player count exceeds a threshold.

Answer

Pre-provision a fixed number of VMs with GPUs to handle peak load at all times.

Question 11

A company wants to adopt a zero-trust security model for accessing Google Cloud resources. Which Google Cloud technology BEST supports this approach?

Accepted Answer

BeyondCorp Enterprise. BeyondCorp Enterprise is Google's zero-trust security model that allows access based on identity and context, without VPNs.

Answer

Cloud VPN

Answer

Cloud Identity-Aware Proxy (IAP)

Answer

Firewall Rules

Question 12

An organization wants to ensure its data is encrypted at rest and in transit by default on Google Cloud. Which statement is correct?

Accepted Answer

Data is encrypted at rest and in transit by default.. Google Cloud encrypts data at rest and in transit by default for many services, with customer-managed keys optional.

Answer

Customers must use CMEK to encrypt data at rest.

Answer

Only data in transit is encrypted by default.

Answer

Encryption is optional and must be enabled by the customer.

Question 13

A company is migrating a legacy application to Google Cloud. The application has variable traffic and requires reliable, low-latency database access. The team wants to minimize operational overhead. Which TWO services should they consider for the database tier? (Choose two.)
