Case Study: Cloud Storage and Databases Quiz Answer

Shelby logs in and starts her day as a tech support agent. First, she reads the following email:

From: [email protected]
To: [email protected]
Subject: Modifications

Hello. I’m having some trouble. I can download and list objects, list buckets, and read bucket metadata, but I can’t make modifications. I need to perform modifications, so please help.

Shelby checks Brett’s service access role, which turns out to be Reader. According to the company policies, the Reader role does not have permissions to perform modifications.

Question 1)
What should Shelby do next?

  • Change Brett’s service access role from Reader to Writer, which will enable him to perform modifications.
  • Call up Brett’s manager and get the necessary approval, and then change Brett’s service access role.
  • Temporarily change the service access role to Writer to enable Brett to make the necessary modifications for this one time, after which revert Brett’s role to Reader.
  • Inform Brett that he has no permissions to perform modifications and that he needs to obtain his manager’s permission before Shelby can change that.


Next, Shelby takes a phone call from another user, Keith.

Shelby: Hi, Keith, this is Shelby. How can I help you today?
Keith: Hi, Shelby. I’m working on a plan to set up cloud storage for my team. I wonder if you can help me understand what type of storage would work best for us.
Shelby: Sure. What are your needs?
Keith: Well, part of the problem is that we’re not sure yet. It’s a new project, so we don’t really know how much information we’ll need to store. We’re still setting everything up.
Shelby: I think you’ll want to look into object storage – that might suit your project well.

Question 2)
Which three of the following are advantages of cloud object storage over block and file storage? Select all that apply.

  • Cheaper than file and block storage
  • Faster than file and block storage
  • Ideal for storing large amounts of unstructured data
  • Effectively infinite in size, highly available and scalable


Keith: That does sound like it might suit our project. What kind of cost should we expect?
Shelby: That usually depends on how much storage you use and the tier of storage you need. You might need more than one type.
Keith: We access some documents frequently but others only once per month. We’ll also need some space for sharing files on our team.

Question 3)
Which tier of object storage would be appropriate for documents that are accessed once per month?

  • Standard tier
  • Common tier
  • Vault tier
  • Cold vault tier


Question 4)
What is an ideal cloud storage type for common storage such as a departmental share, a “landing space” for files that an application will process, or a repository for a web service?

  • Object storage
  • Direct attached storage
  • Block storage
  • File storage


Keith: I think I’m getting an idea of what we may need.
Shelby: Great! Did you have any other concerns?
Keith: We have a geographically-diverse team, and we’ve had trouble in the past with delays and other issues having to do with access for our team members outside the US. Will that continue to be a problem?
Shelby: I think you can help those problems by using a CDN.

Question 5)
From the following options, select two that are benefits of using a CDN. Select all that apply.

  • Media content is not cached.
  • The main server is more secure.
  • Users have faster access speeds for a website.
  • Less storage is needed.


Keith: Thanks for your help! I’m going to have a lot less worry about shopping for our services now.
Shelby: Glad I could help, Keith! Please call back if you run into any more concerns.
