Preparing for your Professional Cloud Architect Journey Coursera Quiz Answers


 

Module 1 Assessment Answers

Question 1)
The Certification Exam is:

  • Theoretical, based only on information.
  • Practical, based on the skills required of the job.

Question 2)
This course helps you prepare using:

  • Sample questions, case studies, and top-down concepts that require knowledge of many dependent concepts.
  • Exhaustive lists of essential concepts (bottom-up), and practice quizzes to help you memorize the majority of the concepts.

Question 3)
The recommended test-taking strategy is:

  • Bookmark those questions for which you don’t know the answer or don’t feel confident in your answer, and return to them iteratively.
  • Answer each question in order and ignore the bookmarking feature.

 

Preparing with Case Studies Quiz Answers

Question 1)
Why are case studies important preparation?

  • Because they give you answers to questions that are on the exam.
  • Because you practice skills needed to identify solutions from circumstances — skills needed on the exam and on the job.

Question 2)
The recommended case analysis method taught in this course is:

  • 1. Identify the requirements
    2. Technical Watchpoints (items that imply parts of the solution)
    3. Propose solution

1. Read the case study
2. Propose solution
3. Verify and correct if needed

Question 3)
The case study solution provided is:

  • Authoritative. The only right solution.
  • Just an example. Your solution might be better.

 


 

Preparing for Design Quiz Answers

Question 1)
When you prepare using tables that compare different technologies…

  • Read from the table-up. So that if you see a keyword in a question, you will recognize which associated technology in the heading row is a candidate for the solution.
  • You don’t really need to know the characteristics of each technology. So it is safe to ignore tables. They have too much information anyway.

Question 2)
Why is knowledge of a layered model a recommended preparation?

  • Because it helps organize information and prevent confusion.
  • Because it tells you which part of a case or problem is most important.

Question 3)

  • Archive
  • Coldline
  • Nearline
  • Standard

 

Preparing for Optimizing and Operating Quiz Answers

Question 1)
What service was recommended as a way to model solution resources and generate a general cost estimation?

  • Google sheets
  • Pricing calculator

Question 2)
What was the key point made about resilient failover design?

  • If the load changes, the capacity has to be revisited, or the ability of the design to handle a failover could be lost.
  • If you account for failover in you initial design you will never need to worry about it again.

Question 3)
What is the feature that bridges monitoring and incident response in the Site Reliability Engineering model?

  • Billing
  • Alerts

Question 4)
Customer Supplied Encryption Keys (CSEK) is for which purpose:

  • Keep keys on premises, and use them to encrypt your cloud services.
  • Data is encrypted before it is sent to the cloud.
