Questions # 11:

Your organization has an existing app that just went viral. The app uses a Cloud SQL for MySQL backend database that is experiencing slow disk performance while using hard disk drives (HDDs). You need to improve performance and reduce disk I/O wait times. What should you do?

Options:

A.

Export the data from the existing instance, and import the data into a new instance with solid-state drives (SSDs).


B.

Edit the instance to change the storage type from HDD to SSD.


C.

Create a high availability (HA) failover instance with SSDs, and perform a failover to the new instance.


D.

Create a read replica of the instance with SSDs, and perform a failover to the new instance


Questions # 12:

You are configuring a new application that has access to an existing Cloud Spanner database. The new application reads from this database to gather statistics for a dashboard. You want to follow Google-recommended practices when granting Identity and Access Management (IAM) permissions. What should you do?

Options:

A.

Reuse the existing service account that populates this database.


B.

Create a new service account, and grant it the Cloud Spanner Database Admin role.


C.

Create a new service account, and grant it the Cloud Spanner Database Reader role.


D.

Create a new service account, and grant it the spanner.databases.select permission.


Questions # 13:

Your company is developing a new global transactional application that must be ACID-compliant and have 99.999% availability. You are responsible for selecting the appropriate Google Cloud database to serve as a datastore for this new application. What should you do?

B.

Use Cloud Spanner.


C.

Use Cloud SQL.


D.

Use Bigtable.


Questions # 14:

An analytics team needs to read data out of Cloud SQL for SQL Server and update a table in Cloud Spanner. You need to create a service account and grant least privilege access using predefined roles. What roles should you assign to the service account?

Options:

Questions # 15:

Your company is migrating all legacy applications to Google Cloud. All on-premises applications are using legacy Oracle 12c databases with Oracle Real Application Cluster (RAC) for high availability (HA) and Oracle Data Guard for disaster recovery. You need a solution that requires minimal code changes, provides the same high availability you have today on-premises, and supports a low latency network for migrated legacy applications. What should you do?

Options:

A.

Migrate the databases to Cloud Spanner.


B.

Migrate the databases to Cloud SQL, and enable a standby database.


C.

Migrate the databases to Compute Engine using regional persistent disks.


D.

Migrate the databases to Bare Metal Solution for Oracle.


Questions # 16:

Options:

A.

Cloud SQL


B.

BigQuery


C.

Cloud Spanner


D.

Bigtable


Questions # 17:

You have deployed a Cloud SQL for SQL Server instance. In addition, you created a cross-region read replica for disaster recovery (DR) purposes. Your company requires you to maintain and monitor a recovery point objective (RPO) of less than 5 minutes. You need to verify that your cross-region read replica meets the allowed RPO. What should you do?

Options:

A.

Use Cloud SQL instance monitoring.


B.

Use the Cloud Monitoring dashboard with available metrics from Cloud SQL.


C.

Use Cloud SQL logs.


D.

Use the SQL Server Always On Availability Group dashboard.


Questions # 18:

You work for a large retail and ecommerce company that is starting to extend their business globally. Your company plans to migrate to Google Cloud. You want to use platforms that will scale easily, handle transactions with the least amount of latency, and provide a reliable customer experience. You need a storage layer for sales transactions and current inventory levels. You want to retain the same relational schema that your existing platform uses. What should you do?

Options:

A.

Store your data in Firestore in a multi-region location, and place your compute resources in one of the constituent regions.


B.

Deploy Cloud Spanner using a multi-region instance, and place your compute resources close to the default leader region.


C.

Build an in-memory cache in Memorystore, and deploy to the specific geographic regions where your application resides.


D.

Deploy a Bigtable instance with a cluster in one region and a replica cluster in another geographic region.


Questions # 19:

Your company uses the Cloud SQL out-of-disk recommender to analyze the storage utilization trends of production databases over the last 30 days. Your database operations team uses these recommendations to proactively monitor storage utilization and implement corrective actions. You receive a recommendation that the instance is likely to run out of disk space. What should you do to address this storage alert?

Options:

A.

Normalize the database to the third normal form.


B.

Compress the data using a different compression algorithm.


C.

Manually or automatically increase the storage capacity.


D.

Create another schema to load older data.


Questions # 20:

You support a consumer inventory application that runs on a multi-region instance of Cloud Spanner. A customer opened a support ticket to complain about slow response times. You notice a Cloud Monitoring alert about high CPU utilization. You want to follow Google-recommended practices to address the CPU performance issue. What should you do first?

Options:

A.

Increase the number of processing units.
