Therefore, the correct answer should include both A and D.

Answer

Cloud Spanner

Answer

Bare Metal Solution for Oracle

Question 2

A customer wants to run a containerized application on Google Cloud with zero downtime during updates and the ability to roll back quickly. Which service and deployment strategy should they use?

Accepted Answer

Cloud Run with manual traffic splitting. Cloud Run allows deploying a new revision and splitting traffic between revisions, achieving zero downtime and allowing immediate rollback by shifting traffic back. This is comparable to GKE rolling updates. Therefore, both B and C are valid.

Answer

Compute Engine with a load balancer and instance group update

Answer

App Engine with automatic scaling

Question 3

A company wants to store data across multiple regions for disaster recovery and comply with data residency requirements in the European Union. Which TWO Google Cloud features should they use?

Accepted Answer

Dual-region Cloud Storage buckets. To comply with EU data residency and store data across multiple regions, both dual-region buckets (e.g., europe-west1 and europe-west4) and multi-region buckets with location 'EU' are appropriate. Multi-region buckets with location 'EU' store data redundantly within the European Union, unlike global multi-region buckets. Object holds are a data protection feature that prevents deletion but does not address multi-region storage or residency.

Answer

Cloud Storage Object holds

Answer

Cloud CDN

Answer

Cloud Interconnect

Question 4

A company wants to reduce its on-premises data centre footprint and improve disaster recovery by migrating to Google Cloud. Which THREE Google Cloud features directly support improved disaster recovery? (Choose 3)

Accepted Answer

Regional persistent disks with synchronous replication. Regional persistent disks provide synchronous replication across zones within a single region, addressing zonal failures. Multi-regional storage classes (e.g., Standard, Nearline) duplicate data across regions, and Cloud Load Balancing with global anycast IP routes traffic to healthy backends in different regions. Together these support improved disaster recovery, though regional persistent disks are primarily an availability feature within a region.

Answer

Cloud Interconnect for dedicated connectivity

Answer

Preemptible VMs for cost savings

Question 5

A financial services company needs to migrate its on-premises data center to Google Cloud to reduce operational overhead and improve scalability. They have a mix of legacy and modern applications. Which approach should they use to minimize migration risk while accelerating their digital transformation?

Accepted Answer

Use Anthos to manage applications across on-premises and Google Cloud, enabling gradual migration.. Anthos provides a consistent platform to run applications on-premises and in Google Cloud, enabling gradual migration without requiring a full rewrite. This minimizes migration risk while accelerating digital transformation because it allows the company to move workloads incrementally. Option A (rewrite all as microservices) is risky and time-consuming for legacy apps. Option C (migrate everything to GKE immediately) may not be suitable for all workloads and increases complexity. Option D (lift-and-shift to Compute Engine) does not address legacy issues and may not fully leverage cloud benefits.

Answer

Rewrite all applications as cloud-native microservices before migration.

Answer

Migrate everything to Google Kubernetes Engine (GKE) immediately.

Answer

Lift and shift all applications to Compute Engine as-is.

Question 6

A company wants to reduce its total cost of ownership (TCO) by migrating from on-premises infrastructure to Google Cloud. Their current on-premises servers are underutilized during off-peak hours. Which Google Cloud feature directly addresses this waste by aligning costs with actual usage?

Accepted Answer

Pay-as-you-go pricing. Preemptible VMs are short-lived and not suitable for general workloads; committed use discounts require upfront commitment; pay-as-you-go pricing aligns costs with actual usage because you only pay for compute resources while they run, allowing you to stop or scale down during off-peak hours. Sustained use discounts reward consistent running time but do not directly address underutilization.

Answer

Preemptible VMs

Answer

Committed use discounts

Answer

Sustained use discounts

Question 7

A company wants to migrate its on-premises Microsoft SQL Server database to Google Cloud. They want to minimize operational overhead and avoid vendor lock-in. Which TWO Google Cloud services should they consider? (Choose 2)

Accepted Answer

Migrate to Cloud SQL for SQL Server. Cloud SQL for SQL Server is a fully managed service that reduces operational overhead for migrating SQL Server databases directly. Cloud Spanner is a fully managed, globally distributed database that avoids vendor lock-in by being a Google proprietary solution, not tied to a specific vendor like Microsoft. After converting the schema from SQL Server to Spanner's relational model, the company gains a scalable, lock-in-free database. Options A (Bigtable) is NoSQL, not suitable for SQL Server; C (Cloud Run) is a compute platform, not a database; E (DMS to Cloud SQL for MySQL) suggests a different target database (MySQL) and may not align with the goal of minimizing overhead (since schema conversion is needed) and avoiding lock-in (MySQL is open source but still a specific vendor).

Answer

Migrate to Cloud Bigtable

Answer

Use Cloud Run for database hosting

Answer

Use Database Migration Service (DMS) to migrate to Cloud SQL for MySQL
