Google Professional Cloud Developer Question 364
Select 4Google Cloud PlatformYou are deploying a web application to Google Kubernetes Engine (GKE). The application requires high availability and needs to handle traffic from users across multiple regions. Which of the following steps should you take to ensure a successful deployment that meets the requirements?
- A
Configure a multi-regional GKE cluster and deploy the application across multiple zones within those regions.
- B
Use a Kubernetes Deployment resource to manage the application pods and ensure they are evenly distributed across zones.
- C
Configure a Horizontal Pod Autoscaler (HPA) to scale pods based on CPU or memory utilization.
- D
Use a regional load balancer to distribute traffic across the cluster.
- E
Deploy the application to a single-zone cluster to minimize latency.
Show answer and explanation
Correct answers: A, B, C, D
Explanation
To ensure high availability and handle global traffic, a combination of multi-regional GKE clusters, Kubernetes Deployments, Horizontal Pod Autoscalers, and regional load balancers is necessary. These components work together to provide fault tolerance, scalability, and effective traffic distribution. Deploying to a single-zone cluster would not fulfill the requirement for high availability and resilience.
- A. Correct.
Configuring a multi-regional GKE cluster and deploying across multiple zones ensures high availability and fault tolerance by distributing workloads across regions and zones.
- B. Correct.
Using a Kubernetes Deployment resource allows for reliable pod management and ensures that pods are distributed across available zones, improving availability.
- C. Correct.
A Horizontal Pod Autoscaler (HPA) helps the application handle fluctuating traffic by automatically scaling pods based on resource usage.
- D. Correct.
A regional load balancer is essential for distributing incoming traffic across the cluster effectively, ensuring users experience low latency and high availability.
- E. Incorrect.
Deploying to a single-zone cluster does not meet the high availability requirement, as it creates a single point of failure.
