You are discussing scaling requirements with a gaming company. When the game launches, they are expecting incoming data surges of 2 million users or more during weekends and holidays. Their on-premise systems have had issues scaling and they want your advice on solving the issue. What do you recommend?

1. A. Either Compute Engine VMs or Kubernetes nodes work, but it is better to keep a buffer of an extra 2 million users.
2. B. We can deploy a Pub/Sub to ingest data which will grow to absorb demand and pass it on to other stages.
3. C. We will allocate Compute Engine VMs estimating 80% capacity of 2 million users.
4. D. We will allocate Kubernetes nodes estimating 80% capacity of 2 million users.

Correct Answer: B
When there are huge surges in demand, it is preferable to use serverless technologies that automatically scale on demand. In this case, the key concern is data ingestion. Pub/Sub is a serverless system that can expand to absorb such demand.

A company with its own private data center has called you in for help with their disaster recovery planning. News of multiple ransomware attacks has made them very anxious. They want to make they are well prepared for such an eventuality. Which of these would be good recommendations?

1. A. It is better to have redundancy; so, set up another private data center nearby so that you can quickly go over in case of an emergency.
2. B. It is better to have redundancy; use one or many of the Google Cloud datacenters as a backup location.
3. C. The one data center is enough, as long as the data is encrypted; attackers won't be able to read the data.
4. D. The one data center is enough as long as you regularly back up data and save it in another place in the same DC.

Correct Answer: B
A single data center is vulnerable. So any option involving that is not good. Reference Link:- https://www.coresite.com/blog/data-center-redundancy
