   You are developing a new mobile game that will be deployed on GKE and Cloud Run as a set of microservices. Currently, there are no projections for the game’s user volume. You need to store the following data types: • Data type 1: leaderboard data • Data type 2: player profiles, chats, and news feed • Data type 3: player clickstream data for BI You need to identify a data storage solution that is easy to use, cost-effective, scalable, and supports offline caching on the user’s device. Which data storage option should you choose for the different data types?

   • A• Data type 1: Memorystore • Data type 2: Firestore • Data type 3: BigQuery
   • B• Data type 1: Memorystore • Data type 2: Spanner • Data type 3: Bigtable
   • C• Data type 1: Firestore • Data type 2: Cloud SQL • Data type 3: BigQuery
   • D• Data type 1: Firestore • Data type 2: Firestore • Data type 3: BigQuery

   Your team developed a web-based game that has many simultaneous players. Recently, users have started to complain that the leaderboard tallies the top scores too slowly. You investigated the issue and discovered that the application stack is currently using Cloud SQL for PostgreSQL. You want to improve the leaderboard performance as much as possible to provide a better user experience. What should you do?

   • ARe-implement the leaderboard data to be stored in Memorystore for Redis.
   • BOptimize the SQL queries to minimize slow-running queries.
   • CMigrate the database and store the data in AlloyDB.
   • DUpdate Cloud SQL for PostgreSQL to the latest version.

   You are a developer at a large corporation. You manage three GKE clusters. Your team’s developers need to switch from one cluster to another regularly on the same workstation. You want to configure individual access to these multiple clusters securely while following Google-recommended practices. What should you do?

   • AAsk the developers to use Cloud Shell and run the gcloud container clusters get-credentials command to switch to another cluster.
   • BAsk the developers to open three terminals on their workstation and use the kubectl config set command to configure access to each cluster.
   • CAsk the developers to install the gcloud CLI on their workstation and run the gcloud container clusters get-credentials command to switch to another cluster.
   • DIn a text file, define the clusters, users, and contexts. Email the file to the developers and ask them to use the kubectl config set command to add cluster, user, and context details to the file.

   You are tasked with using C++ to build and deploy a microservice for an application hosted on Google Cloud. The code needs to be containerized and use several custom software libraries that your team has built. You want to minimize maintenance of the application’s underlying infrastructure. How should you deploy the microservice?

   • AUse Cloud Run functions to deploy the microservice.
   • BUse Cloud Build to create the container, and deploy it on Cloud Run.
   • CUse Cloud Shell to containerize your microservice, and deploy it on GKE Standard.
   • DUse Cloud Shell to containerize your microservice, and deploy it on a Container-Optimized OS Compute Engine instance.

6. Question 356 · 357 in bank

   Your team is trying to reduce their cloud spend, and you want to evaluate your GKE Autopilot cluster costs. When reviewing the manifests, you see that resource requests are currently not specified. Your application is stateless and fault-tolerant, and there are no specific hardware or memory requirements on nodes. You want to modify the cluster to be scalable and cost-effective as quickly as possible while maintaining a cluster with sufficient computing resources. What should you do?

   • ARequest that your Pods run as Spot Pods, and use the cloud.google.com/gke-spot=true label in your YAML manifest.
   • BRequest the Balanced compute class in your YAML manifest.
   • CIn the YAML deployment configuration manifest, request and set the maximum CPU to 5 vCPU.
   • DSet up Cloud Trace and Cloud Monitoring, identify the maximum memory used in the past 30 days, and set the YAML manifest to request that amount of memory.

7. Question 357 · 357 in bank

   You are building an application that will store frequently accessed data in a Memorystore for Redis Cluster instance. You would like to make the application resilient to network issues. You need to ensure that the application handles client disconnections from a Redis instance gracefully to minimize disruption and ensure stability of the application. What should you do?

   • AImmediately terminate the application instance upon detecting a Redis disconnection to force a restart, and wait for clients to reconnect to the cache as soon as the application becomes available.
   • BConfigure the Redis client to reconnect after a fixed delay of 60 seconds.
   • CUse Memorystore’s automatic failover mechanisms to make the Redis cache available in a secondary zone.
   • DImplement exponential backoff with a jitter when reconnecting after a disconnection. Configure client-side caching to serve data during brief outages.
