The Good Parts of AWS: Cutting Through the Clutter Educative Quiz Answers
Get The Good Parts of AWS: Cutting Through the Clutter Educative Quiz Answers
This is not your typical AWS reference course. You won’t find most of the knowledge that’s shared here in the AWS docs. The goal here is to help you realize which AWS features you’d be foolish not to use — features that have passed the test of time by being at the backbone of most things on the Internet.
In this course, you’ll learn a technique used to help make reliable technical choices without getting paralyzed in the face of so many options. You’ll start by going through the most fundamental services AWS offers such as DynamoDB, S3, EC2. Each section breaks down how it’s used, the pros and cons, why you should (or shouldn’t) be using it, and more.
Quiz 1: What is this course about?
Q1. Which of the following is the central application in the AWS fleet of services?
- Amazon Elastic Compute Cloud
- Amazon Simple Queue Service
- Amazon Simple Notification Service
- Amazon Simple Storage System
Quiz 2: The Default Heuristic
Q1. What should your default choice be?
- It has to be a theoretical best choice.
- It has to be the most efficient.
- It should be a reliable option to get to your ultimate desirable outcome.
- It has to be the latest or the greatest.
Quiz 3: Database: DynamoDB
Q1. One of the major differences between DynamoDB and relational database is that in DynamoDB, data aggregration is done close to the data as opposed to relational database.
- True
- False
Quiz 4: Database: DynamoDB
Q1. With on-demand request pricing, you will have the burden to monitor your utilization and proactively provision the necessary capacity.
- True
- False
Quiz 5: Storage: S3
Q1. S3 is a highly-durable hash table in the cloud. The key can be any string, and the value any blob of data up to ______ TB?
- 7TB
- 10TB
- 3TB
- 5TB
Quiz 6: Compute: EC2
Q1. The biggest benefit in using EC2 instances is: you pay for the number of seconds an instance is being used and not by the number of seconds an instance is running.
- True
- False
Quiz 7: Compute: EC2 Auto Scaling
Q1. Headroom acts as a safety buffer that can absorb many types of unpredictable events.
- True
- False
Quiz 8: Compute: EC2 Auto Scaling
Q1. One of the limitations of Auto Scaling is that you have to manually remove an instance from the auto scaling group if it becomes unhealthy.
- True
- False
Quiz 9: Compute: Lambda
Q1. Unlike S3, it is very hard to run a sophisticated piece of software on Lambda without making some very drastic changes to your application.
- True
- False
Quiz 10: Networking & Content Delivery: ELB
Q1. NLBs are proper reverse proxies that sit between the internet and your application.
- True
- False
Quiz 11: Networking & Content Delivery: Route 53
Q1. Route 53 provides support for ALIAS records as long as they point to AWS resources.
- True
- False
Quiz 12: Management & Governance: CloudFormation
Q1. CloudFormation lets you create and update the things you have in AWS without having to click around on the console or write fragile scripts.
- True
- False
Quiz 13: Application Integration: SQS
Q1. In SQS, there is no strict ordering because SQS queue is actually a bunch of queues behind the scenes and duplicate messages can emerge within SQS too.
- True
- False
Quiz 14: Media Service: Kinesis
Q1. Once a Kinesis message gets consumed, it gets deleted from the queue as opposed to SQS where it is appended to the end of the file.
- True
- False
Quiz 15: Basic AWS Services
Q1. The other nice thing that comes with ______ is the ability to simply add or remove instances just by updating the desired capacity setting.
- CloudFormation
- Autoscaling
- EC2
- CloudWatch
Q2. The nice thing about EC2 is that the computer you get will be very similar to the computer you use to develop your software.
- True
- False
Q3. Unlike SQS, records in a Kinesis stream don’t get deleted when consumed, so it’s a pure append-only data structure behind the scenes.
- True
- False
Q4. Fundamentally, you can think of ______ as a highly-durable hash table in the cloud.
- DynamoDB
- EC2
- CloudFormation
- S3
Q5. NLB behaves like a single-tenant system. AWS keeps track of your request rates and then automatically scales your NLB up or down based on the demand it sees.
- True
- False
Q6. ______ doesn’t come with an API to resize an image after uploading it to a bucket, but with Lambda, you can add that capability.
- EC2
- CloudFormation
- S3
- Route 53
Q7. Application load balancers come with an API to respond with a fixed response for a given route, but they can’t respond with an image. ______ lets you make your load balancer do that.
- EC2
- Lambda
- SQS
- DynamoDB
Q8. If we have a small piece of code that will rarely need to be changed and that needs to run in response to something that happens in our AWS account, then ______ is a very good default choice.
- Lambda
- EC2
- CloudFormation
- ELB
Q9. The number of messages stored in SQS (the backlog size) is limited.
- True
- False
Q10. ______ doesn’t support regex-based alerting on application logs.
- EC2
- CloudFormation
- CloudWatch
- Lambda
