Common confusions include mixing tool names and migration strategies.

Answer

Lift and Shift: Tool for migrating VMs to GCP

Answer

Replatform: Re-architecting applications to be cloud-native

Question 3

A mid-sized company runs a legacy inventory management system on a single on-premises server. The system uses a monolithic Java application and a PostgreSQL database. The server has reached 90% CPU usage during business hours, and the database is 800 GB. The company wants to migrate to Google Cloud to take advantage of autoscaling and reduce hardware costs. The migration must have minimal downtime and the application cannot be significantly rewritten. The team also wants to enable future scalability for peak seasons. The IT team includes experienced database administrators but limited application development resources. Given the constraints, which approach should the team take?

Accepted Answer

Use Database Migration Service to migrate the PostgreSQL database to Cloud SQL with continuous replication for minimal downtime. Simultaneously, rehost the application on a managed instance group with autoscaling. Have a rollback plan.. It combines Database Migration Service with continuous replication (CDC) to achieve near-zero downtime for the 800 GB PostgreSQL database, while rehosting the monolithic application on a managed instance group with autoscaling to address CPU spikes without code changes. This approach respects the constraint of limited app development resources by avoiding refactoring, and the rollback plan provides safety during migration.

Answer

Containerize the entire monolithic application and deploy it on Google Kubernetes Engine with a persistent volume for the database, with horizontal pod autoscaling.

Answer

Use Database Migration Service to migrate the PostgreSQL database to Cloud SQL with a one-time dump and restore, and rehost the application on a single Compute Engine instance.

Answer

Refactor the monolithic application into microservices, deploy on Cloud Run, and use Cloud Spanner for the database.

Question 4

A retail company needs to handle sudden spikes in customer traffic during holiday promotions without over-provisioning hardware. Which cloud characteristic directly enables this capability?

Question 6

A company wants to use Google Cloud to innovate faster by leveraging managed services. Which TWO benefits are directly associated with using managed services? (Choose 2)

Accepted Answer

Reduced operational overhead (no patching, no server management). Managed services reduce operational overhead (no patching, no infrastructure management) and often provide built-in high availability and scaling. They do increase flexibility but may reduce control over the underlying infrastructure.

Answer

Increased control over the underlying hardware

Answer

Requires more staff to manage

Answer

Higher cost compared to self-managed solutions

Question 7

An organization wants to ensure business continuity by failing over to a secondary region in case of disaster. Which cloud characteristic enables this capability?

Accepted Answer

Global infrastructure. Global infrastructure refers to the distributed network of data centers across multiple geographic regions. By deploying resources in a secondary region, an organization can fail over to that region during a disaster, ensuring business continuity. This capability is unique to the cloud's global footprint, not to other characteristics like scalability or measured service.

Answer

Scalability

Answer

Measured service

Answer

Resource pooling

Question 8

A company wants to deploy a multi-tier web application on Google Cloud that requires high availability across zones. The application consists of a stateless web frontend and a stateful database backend. Which TWO actions should the company take to meet the high availability requirement? (Select two.)

Accepted Answer

Use a regional managed instance group for the web frontend. To achieve high availability across zones, the frontend should be deployed in multiple zones behind a load balancer, and the database should be configured with replication across zones. Using a single large instance for the database creates a single point of failure. Regional managed instance groups distribute instances across zones.

Answer

Place all resources in the same zone to simplify management

Answer

Configure the database as a single large instance with automatic backups

Answer

Deploy the web frontend in a single zone to reduce network latency

Question 9

A company wants to implement a zero-trust security model for accessing internal applications. Which TWO Google Cloud services should they use together? (Choose 2)

Accepted Answer
