Google Certified Professional - Cloud Developer 認定 Professional-Cloud-Developer 試験問題 (Q307-Q312):

質問 # 307
You are deploying your application to a Compute Engine virtual machine instance with the Stackdriver Monitoring Agent installed. Your application is a unix process on the instance. You want to be alerted if the unix process has not run for at least 5 minutes. You are not able to change the application to generate metrics or logs.
Which alert condition should you configure?

A. Metric absence
B. Process health
C. Metric threshold
D. Uptime check

正解：B

解説：

質問 # 308
Your team develops stateless services that run on Google Kubernetes Engine (GKE). You need to deploy a new service that will only be accessed by other services running in the GKE cluster.
The service will need to scale as quickly as possible to respond to changing load. What should you do?

A. Use a Vertical Pod Autoscaler to scale the containers, and expose them via a NodePort Service.
B. Use a Horizontal Pod Autoscaler to scale the containers, and expose them via a NodePort Service.
C. Use a Vertical Pod Autoscaler to scale the containers, and expose them via a ClusterIP Service.
D. Use a Horizontal Pod Autoscaler to scale the containers, and expose them via a ClusterIP Service.

正解：D

解説：
https://cloud.google.com/kubernetes-engine/docs/concepts/service#services_of_type_clusterip When you create a Service of type ClusterIP, Kubernetes creates a stable IP address that is accessible from nodes in the cluster.
https://cloud.google.com/kubernetes-engine/docs/concepts/horizontalpodautoscaler The Horizontal Pod Autoscaler changes the shape of your Kubernetes workload by automatically increasing or decreasing the number of Pods in response to the workload's CPU or memory consumption, or in response to custom metrics reported from within Kubernetes or external metrics from sources outside of your cluster.

質問 # 309
You are developing an application that will store and access sensitive unstructured data objects in a Cloud Storage bucket. To comply with regulatory requirements, you need to ensure that all data objects are available for at least 7 years after their initial creation. Objects created more than 3 years ago are accessed very infrequently (less than once a year). You need to configure object storage while ensuring that storage cost is optimized. What should you do? (Choose two.)

A. Use IAM Conditions to provide access to objects 7 years after the object creation date.
B. Create an object lifecycle policy on the bucket that moves objects from Standard Storage to Archive Storage after 3 years.
C. Enable Object Versioning to prevent objects from being accidentally deleted for 7 years after object creation.
D. Implement a Cloud Function that checks the age of each object in the bucket and moves the objects older than 3 years to a second bucket with the Archive Storage class. Use Cloud Scheduler to trigger the Cloud Function on a daily schedule.
E. Set a retention policy on the bucket with a period of 7 years.

正解：B、E

解説：
https://cloud.google.com/storage/docs/bucket-lock
This page discusses the Bucket Lock feature, which allows you to configure a data retention policy for a Cloud Storage bucket that governs how long objects in the bucket must be retained. The feature also allows you to lock the data retention policy, permanently preventing the policy from being reduced or removed.
https://cloud.google.com/storage/docs/storage-classes#archive
Archive storage is the lowest-cost, highly durable storage service for data archiving, online backup, and disaster recovery. Unlike the "coldest" storage services offered by other Cloud providers, your data is available within milliseconds, not hours or days.
Archive storage is the best choice for data that you plan to access less than once a year.

質問 # 310
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. 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.
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. 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.
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.

正解：A

質問 # 311
You work for an organization that manages an ecommerce site. Your application is deployed behind an external Application Load Balancer. You need to test a new product recommendation algorithm. You plan to use A/B testing to determine the new algorithm's effect on sales in a randomized way. How should you test this feature?

A. Enable the new recommendation feature flag on a single instance.
B. Use HTTP header-based routing.
C. Split traffic between versions using weights.
D. Mirror traffic to the new version of your application.

正解：C

解説：
A/B testing requires distributing traffic in a controlled, randomized manner between different versions of your application. Weighted traffic splitting allows you to direct a specific percentage of traffic to the new version (with the new algorithm) and the rest to the current version. This approach provides a statistically valid way to compare the two versions' performance and assess the impact on sales.
HTTP header-based routing could target specific user segments but would not ensure random distribution for A/B testing. Mirroring traffic duplicates requests without user interactions being served by the new version, which doesn't provide direct test results. Enabling the feature on a single instance does not provide a randomized, scalable test approach.
