Security :Reliable Google Cloud Infrastructure: Design and Process (Preparing for Google Cloud Certification: Cloud Architect Professional Certificate) Answers 2025
Question 1
What do you have to do to enable encryption when using Cloud Storage?
π© Nothing as encryption is enabled by default.
β Create an encryption key using Cloud KMS
β Enable encryption and upload a key
β Simply enable encryption when configuring a bucket
Explanation:
Cloud Storage always encrypts data at rest by default using Google-managed keys.
Customer-managed keys (CMEK) are optionalβnot required.
Question 2
Which Google Cloud features could help reduce the risk of DDoS attacks?
β Global external Application Load Balancer
π© All of these
β Google Cloud Armor
β Cloud CDN
Explanation:
All listed features contribute to DDoS mitigation:
-
Cloud Armor β DDoS protection & WAF
-
Cloud CDN β reduces load on origin servers
-
Global Load Balancer β distributes traffic globally
Therefore, All of these is correct.
Question 3
You don’t want programmers to have access to production resources. Whatβs the easiest solution?
β Use different service accounts
β Create firewall rules
π© Create development and production projects, and don’t give developers access to production.
β Use private access + IAP
Explanation:
The simplest and recommended Google Cloud practice is:
Separate dev/test and prod into different projects and restrict IAM access.
Question 4
What Google Cloud service helps enforce least privilege?
β Firewall rules
β SSL certificates
π© IAM members and roles
