GCP (Google Cloud Platform) fundamentals sample question with answer 50

Question:
What do you have to do to enable encryption when using Cloud Storage?

1. Create an encryption key using Cloud Key Management Service, and select it when creating a Cloud Storage bucket
2. Enable encryption and upload a key
3. Simply enable encryption when configuring a bucket
4. Nothing as encryption is enabled by default

Answer:
D - this answer is correct, because Cloud Storage always encrypts data on the server side before it is written to disk. For server side encryption there are options of customer supplied or customer managed encryption keys, but these are only usually used for compliance reasons and are not necessary
