Identify the best practice for managing GCP resource configurations

You want to ensure that your Google Cloud Platform (GCP) resources are consistently configured and changes are tracked over time. Which approach aligns best with operational excellence principles?

A Rely on default settings for all resources and adjust only when errors occur.

B Manually configure resources through the GCP Console each time a change is needed.

C Use Infrastructure as Code (IaC) tools like Deployment Manager or Terraform to define and manage resource configurations.

D Document configurations in a spreadsheet and update it after manual changes.

💡 Hint

Think about how to automate and track changes to avoid manual errors.

Using Infrastructure as Code tools allows you to automate resource provisioning, maintain version control, and ensure consistent configurations, which supports operational excellence.

Understanding Cloud Monitoring alert behavior

You set up an alert policy in Google Cloud Monitoring to notify you when CPU usage exceeds 80% for 5 minutes. What will happen if the CPU usage spikes to 85% for 3 minutes and then drops back to 70%?

A Multiple alert notifications will be sent every minute during the spike.

B An alert notification will be sent immediately when CPU usage hits 85%.

C An alert notification will be sent after the CPU usage drops below 80%.

D No alert notification will be sent because the threshold was not exceeded for the full 5 minutes.

💡 Hint

Consider how alert conditions use duration to avoid false alarms.

Alert policies with duration require the condition to be true continuously for that time before triggering. A 3-minute spike is too short to trigger the alert.

Securing access to GCP resources with least privilege

You want to grant a team member access to only view logs in Cloud Logging but prevent them from modifying or deleting logs. Which IAM role should you assign?

A roles/logging.viewer

B roles/logging.admin

C roles/editor

D roles/owner

💡 Hint

Choose the role that provides read-only access to logs.

The roles/logging.viewer role grants read-only access to logs, following the principle of least privilege.

Understanding the role of SLOs in operational excellence

What is the primary purpose of defining Service Level Objectives (SLOs) in a cloud environment?

A To set fixed prices for cloud services.

B To define measurable targets for service reliability and performance.

C To list all possible errors that can occur in a service.

D To automate deployment pipelines.

💡 Hint

Think about how teams measure and improve service quality.

SLOs specify measurable goals for service uptime and performance, helping teams maintain operational excellence.

Designing fault-tolerant GCP infrastructure

You are designing a critical application on GCP that must remain available even if an entire region fails. Which architecture choice best supports this requirement?

A Use multi-region deployment with load balancing and data replication across regions.

B Deploy all resources in a single zone within one region for simplicity.

C Deploy resources in multiple zones within the same region without cross-region replication.

D Rely on automatic backups in one region and restore manually if failure occurs.

💡 Hint

Consider how to handle entire region outages without downtime.

Multi-region deployment with load balancing and data replication ensures availability even if one region fails, supporting fault tolerance and operational excellence.
