Leveraging the AWS Global Infrastructure Quiz

Question 1

Which Route 53 Routing Policies would you use to route traffic to multiple resources in proportions that you specify?

1 - Simple Routing Policy
2 - Weighted Routing Policy
3 - Latency Routing Policy
4 - Failover Routing Policy

Answer 1

Weighted Routing Policy

Weighted Routing Policy is used to route traffic to multiple resources in proportions that you specify.

Question 2

You need to enable fast, easy, and secure transfers of files over long distances on S3. Which service would you use?

1 - AWS Global Accelerator
2 - S3 Transfer Acceleration
3 - S3 Cross Region Replication

Answer 2

S3 Transfer Acceleration

Amazon S3 Transfer Acceleration enables fast, easy, and secure transfers of files over long distances between your client and an S3 bucket.

Transfer Acceleration takes advantage of Amazon CloudFront’s globally distributed edge locations. As the data arrives at an edge location, data is routed to Amazon S3 over an optimized network path.

Question 3

What does AWS CloudFront use to improve read performance?

1 - DDoS Protection
2 - S3 Buckets Fast Read
3 - Caching Content in Edge Locations
4 - Caching Content in Edge Regions

Answer 3

Caching Content in Edge Locations

CloudFront uses Edge Location to cache content, and therefore bring more of your content closer to your viewers to improve read performance.

Question 4

Which of the following statements is NOT a reason for a global application?

1 - Decreased Latency
2 - Disaster Recovery
3 - Scale Elasticity on Demand
4 - Attack Protection

Answer 4

Scale Elasticity on Demand

A global application is not specifically used to scale elastically on demand. You can use Auto Scaling Groups for example if you want to elastically scale based on demand.

Question 5

Which features are available with Route 53?

1 - Health Checks, Auto Scaling, Routing Policy, DNS
2 - Load Balancing, DNS, Domain Registration, Monitoring
3 - Domain Registration,Health Checks, DNS, DoS Protection
4 - Domain Registration,Health Checks, DNS,Routing Policy

Answer 5

4 - Domain Registration,Health Checks, DNS,Routing Policy

Route 53 features are (non exhaustive list):

• Domain Registration,
• DNS,
• Health Checks,
• Routing Policy

Question 6

With which services does CloudFront integrate to protect against web attacks?

1 - WAF & Shield
2 - WAF & IAM
3 - IAM & Shield
4 - Security Groups & Shield

Answer 6

WAF & Shield

You can use AWS WAF web access control lists (web ACLs) to help minimize the effects of a distributed denial of service (DDoS) attack. For additional protection against DDoS attacks, AWS also provides AWS Shield Standard and AWS Shield Advanced.
