Professional Cloud Developer Hiplocal Practice Questions

For this question refer to the HipLocal case study. HipLocal wants to reduce the latency of their services for users in global locations. They have created read replicas of their database in locations where their users reside and configured their service to read traffic using those replicas. How should they further reduce latency for all database interactions with the least amount of effort?

• AA. Migrate the database to Bigtable and use it to serve all global user traffic.
• BB. Migrate the database to Cloud Spanner and use it to serve all global user traffic.
• CC. Migrate the database to Firestore in Datastore mode and use it to serve all global user traffic.
• DD. Migrate the services to Google Kubernetes Engine and use a load balancer service to better scale the application.

In order for HipLocal to store application state and meet their stated business requirements, which database service should they migrate to?

• AA. Cloud Spanner
• BB. Cloud Datastore
• CC. Cloud Memorystore as a cache
• DD. Separate Cloud SQL clusters for each region

HipLocal is configuring their access controls. Which firewall configuration should they implement?

• AA. Block all traffic on port 443.
• BB. Allow all traffic into the network.
• CC. Allow traffic on port 443 for a specific tag.
• DD. Allow all traffic on port 443 into the network.

HipLocal's.net-based auth service fails under intermittent load. What should they do?

• AA. Use App Engine for autoscaling.
• BB. Use Cloud Functions for autoscaling.
• CC. Use a Compute Engine cluster for the service.
• DD. Use a dedicated Compute Engine virtual machine instance for the service.

Which service should HipLocal use for their public APIs?

• AA. Cloud Armor
• BB. Cloud Functions
• CC. Cloud Endpoints
• DD. Shielded Virtual Machines

HipLocal's APIs are showing occasional failures, but they cannot find a pattern. They want to collect some metrics to help them troubleshoot. What should they do?

• AA. Take frequent snapshots of all of the VMs.
• BB. Install the Stackdriver Logging agent on the VMs.
• CC. Install the Stackdriver Monitoring agent on the VMs.
• DD. Use Stackdriver Trace to look for performance bottlenecks.
