Q

What is AWS CloudFront?

A

Content Delivery Network (CDN)

Improves read performance, content is cached at the edge, and DDoS protection

17
Q

What can CloudFront cache from?

A

S3 bucket and Custom Origin (HTTP)

18
Q

What is difference between CloudFront vs S3 Cross Region Replication?

A

CloudFront is for global edge network, files are cached for maybe a day and is good for static content

S3 Cross Region Replication is for dynamic content that needs to be available at low-latency in a few regions

19
Q

What is S3 Transfer Acceleration?

A

Increase transfer speed by transferring file to an AWS edge location which will forward the data to the S3 bucket in the target region

Used for uploading or downloading data from S3 buckets around the world

20
Q

What is AWS Global Accelerator?

A

Improve global application availability and performance using the AWS global network. Leverage the AWS internal network to optimize the route to your application (60% better)

21
Q

What is AWS Outposts?

A

For hybrid cloud. Server racks that offers the same AWS infrastructure, services, APIs, and tools to build your own applications on-premises just as in the cloud. AWS will setup and manage them within your on-premises infrastructure, but you are responsible for the Outposts Rack physical security

22
Q

What are the benefits of AWS Outposts?

A
  1. Low latency access to on-premises systems
  2. Local data processing
  3. Data residency
  4. Easier migration from on-premises to the cloud
  5. Fully managed service (except physical security)
23
Q

What is AWS WaveLength?

A

WaveLength Zones are infrastructure deployments embedded within the telecommunications providers’ data-centers at the edge of the 5G networks. Ultra low latency and traffic doesn’t leave the Communication Service Provider’s network. High bandwidth and secure connection to the parent AWS region

24
Q

What is the cost for AWS WaveLength?

A

No extra cost

25
Q

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
A

Weighted Routing Policy

26
Q

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
A

S3 Transfer Acceleration

27
Q

What does AWS CloudFront use to improve read performance?

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

Caching Content in Edge Locations

28
Q

Which service can be used to run AWS infrastructure and services on-premises for a hybrid cloud architecture?

  1. CloudFront
  2. Outposts
  3. DMS
  4. Storage Gateway
A

Outposts

29
Q

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

  1. Decreased Latency
  2. Disaster Recovery
  3. Scale elastically on demand
  4. Attack protection
A

Scale elastically on demand

30
Q

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, DNS, Health Checks, DDoS Protection
  4. Domain Registration, DNS, Health Checks, Routing Policy
A

Domain Registration, DNS, Health Checks, Routing Policy

31
Q

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

  1. WAF & Shield
  2. WAF & IAM
  3. IAM & Shield
  4. Security Groups & WAF
A

WAF & Shield

32
Q
