You are developing a mobile application that allows users to create and manage to-do lists. Your application has the following requirements:
- Store and synchronize data between different mobile devices.
- Support offline access.
- Provide real-time updates on each user's device.
You need to implement a database solution while minimizing operational effort. Which approach should you use?

• A.Create a Cloud SQL for MySQL instance. Implement a data model to store to-do list information.
  Create indexes for the most heavily and frequently used queries.
• B.Create a Bigtable instance. Design a database schema to avoid hotspots when writing data. Use a Bigtable change stream to capture data changes.
• C.Use Firestore as the database. Configure Firestore offline persistence to cache a copy of the Firestore data. Listen to document changes to update applications whenever there are document changes.
• D.Implement a SQLite database on each user's device. Use a scheduled job to synchronize each device database with a copy stored in Cloud Storage.

You are building a highly available and globally accessible application that will serve static content to users. You need to configure the storage and serving components. You want to minimize management overhead and latency while maximizing reliability for users. What should you do?

• A.1. Create a managed instance group. Replicate the static content across the virtual machines (VMs)
  2. Create an external HTTP(S) load balancer.
  3. Enable Cloud CDN, and send traffic to the managed instance group.
• B.1. Create an unmanaged instance group. Replicate the static content across the VMs.
  2. Create an external HTTP(S) load balancer
  3. Enable Cloud CDN, and send traffic to the unmanaged instance group.
• C.1. Create a Standard storage class, regional Cloud Storage bucket. Put the static content in the bucket
  2. Reserve an external IP address, and create an external HTTP(S) load balancer
  3. Enable Cloud CDN, and send traffic to your backend bucket
• D.1. Create a Standard storage class, multi-regional Cloud Storage bucket. Put the static content in the bucket.
  2. Reserve an external IP address, and create an external HTTP(S) load balancer.
  3. Enable Cloud CDN, and send traffic to your backend bucket.

You are working on a social media application. You plan to add a feature that allows users to upload images. These images will be 2 MB - 1 GB in size. You want to minimize their infrastructure operations overhead for this feature. What should you do?

• A.Change the application to accept images directly and store them in the database that stores other user information.
• B.Change the application to create signed URLs for Cloud Storage. Transfer these signed URLs to the client application to upload images to Cloud Storage.
• C.Set up a web server on GCP to accept user images and create a file store to keep uploaded files. Change the application to retrieve images from the file store.
• D.Create a separate bucket for each user in Cloud Storage. Assign a separate service account to allow write access on each bucket. Transfer service account credentials to the client application based on user information. The application uses this service account to upload images to Cloud Storage.

You are developing an application hosted on Google Cloud that uses a MySQL relational database schema.
The application will have a large volume of reads and writes to the database and will require backups and ongoing capacity planning. Your team does not have time to fully manage the database but can take on small administrative tasks. How should you host the database?

• A.Configure Cloud SQL to host the database, and import the schema into Cloud SQL.
• B.Deploy MySQL from the Google Cloud Marketplace to the database using a client, and import the schema.
• C.Configure Bigtable to host the database, and import the data into Bigtable.
• D.Configure Cloud Spanner to host the database, and import the schema into Cloud Spanner.
• E.Configure Firestore to host the database, and import the data into Firestore.
