Question 3

You have the task of deploying a stateless Node.js already containerized application with a scalable configuration so that the start of a new instance is fast and easy to update.

Additional requirements for the instances are:

Ubuntu-1804-lts
Nodejs 10
Free from boot or kernel-level malware or rootkits.

Which is the best solution?

A. Instance Json Template with startup script
B. Instance custom image Template
C. Instance public image Template with startup script
D. Instance shielded public image Template with startup script

Answer

Correct Answer: D

A is wrong. It is not the fastest way (images are quicker) and don’t malware protection

B is wrong. It is the fastest but it don’t have malware protection

C is wrong. It doesn’t have malware protection

D is correct

The key requirement is that is needed for the Shielded VM support, so you are compelled to use a Public Image. See https://cloud.google.com/compute/docs/images

Instance template may use a public image and a startup script to prepare the instance after it starts running.

Custom images are more deterministic and start more quickly than instances with startup scripts. However, startup scripts are more flexible and allow you to update the applications and settings in your instances more easily.
