Leveraging the AWS Global Infrastructure

Question 1

Global DNS service that can be used to route users to the closest deployment with the least amount of latency

Answer 1

Route 53

Question 2

Global Content Delivery Network (CDN) service that replicates parts of your application to AWS Edge Locations to decrease latency and cache common requests

Answer 2

CloudFront

Question 3

Service that increases transfer speeds from all around the world to a single S3 bucket by first transferring files to an AWS Edge Location, then sending them to the S3 bucket via AWS’ private network

Answer 3

S3 Transfer Accelleration

Question 4

Service that improves global application availability and performance using the AWS global network

Answer 4

AWS Global Accelerator

Question 5

What is the difference between Global Accelerator and Cloudfront?

Answer 5

Cloudfront is a Content Delivery Network that serves content from the edge while Global Accelerator improves performance of user’s traffic to your application

Question 6

Server racks that allow you to treat internal servers like they are AWS cloud servers

Answer 6

AWS Outposts

Question 7

Infrastructure deployments embedded within the telecommunications providers’ datacenters at the edge of 5G networks; used for ultra-low latency applications through 5G networks

Answer 7

AWS Wavelength

Question 8

Service that places AWS compute, storage, database, and other AWS services closer to end users to run latency-sensitive applications; extension of an AWS Region that typically is available in major metropolitan areas

Answer 8

AWS Local Zones

Question 9

Global architecture where reads/writes are only done using the Active EC2 instance while a passive EC2 is available in a separate region, but is read-only; improves global read latency

Answer 9

Multi-Region, Active-Passive

Question 10

Global architecture where multiple EC2 instances, existing in different regions, can take write and read actions; replication is constantly happening between the regions

Answer 10

Multi Region, Active-Active

Question 11

Route 53 routing policy that contains no health checks; a web browser sends a web address to the DNS system and gets an IP back

Answer 11

Simple Routing Policy

Question 12

Route 53 routing policy that allows us to distribute traffic across multiple EC2 instances as well as specify that traffic distribution

Answer 12

Weighted Routing Policy

Question 13

Route 53 routing policy that directs users to closest server based on their geographic location

Answer 13

Latency Routing Policy

Question 14

Route 53 routing policy that sends traffic to secondary instance if the health check on the primary instance fails

Answer 14

Failover routing policy

Question 15

Which aspect of AWS infrastructure enables global deployment of compute and storage?
A) Availability Zones
B) Regions
C) Tags
D) Resource Groups

Answer 15

B) Regions
