Q3. Your website is serving on-demand training videos to your workforce. Videos are uploaded monthly in high resolution MP4 format. Your workforce is distributed globally often on the move and using company-provided tablets that require the HTTP Live Streaming (HLS) protocol to watch a video. Your company has no video transcoding expertise and it required you may need to pay for a consultant.

How do you implement the most cost-efficient architecture without compromising high availability and quality of video delivery'?

A. A video transcoding pipeline running on EC2 using SQS to distribute tasks and Auto Scaling to adjust the number of nodes depending on the length of the queue. EBS volumes to host videos and EBS snapshots to incrementally backup original files after a few days. CIoudFront to serve HLS transcoded videos from EC2.

B. Elastic Transcoder to transcode original high-resolution MP4 videos to HLS. EBS volumes to host videos and EBS snapshots to incrementally backup original files after a few days. CIoudFront to serve HLS transcoded videos from EC2.

C. Elastic Transcoder to transcode original high-resolution NIP4 videos to HLS. 53 to host videos with Lifecycle Management to archive original files to Glacier after a few days. C|oudFront to serve HLS transcoded videos from 53.

D. A video transcoding pipeline running on EC2 using SQS to distribute tasks and Auto Scaling to adjust the number of nodes depending on the length of the queue. 53 to host videos with Lifecycle Management to archive all files to Glacier after a few days. CIoudFront to serve HLS transcoded videos from Glacier.

C. The user can set the serverside encryption flag to encrypt the data stored on Glacier.

B. Auto Scaling will raise an alarm and send a notification to the user for action.

C. Auto Scaling must configure the schedule actMty that terminates the instance after 5 days.

D. Auto Scaling will terminate the experiment.

Q7. A read only news reporting site with a combined web and application tier and a database tier that receives large and unpredictable traffic demands must be able to respond to these traffic fluctuations automatically. What AWS services should be used meet these requirements?

A. Stateless instances for the web and application tier synchronized using Elasticache Memcached in an autoscaimg group monitored with CIoudWatch. And RDSwith read replicas.

B. Stateful instances for the web and application tier in an autoscaling group monitored with CIoudWatch and RDS with read replicas.

C. Stateful instances for the web and application tier in an autoscaling group monitored with CIoudWatch. And multi-AZ RDS.

D. Stateless instances for the web and application tier synchronized using EIastiCache Memcached in an autoscaling group monitored with CIoudWatch and multi-AZ RDS.

Q8. You need a persistent and durable storage to trace call actMty of an IVR (Interactive Voice Response) system. Call duration is mostly in the 2-3 minutes timeframe. Each traced call can be either active or terminated. An external application needs to know each minute the list of currently active calls, which are usually a few calls/second. Put once per month there is a periodic peak up to 1000 calls/second for a few hours. The system is open 24/7 and any downtime should be avoided.

Historical data is periodically archived to files. Cost saving is a priority for this project.

What database implementation would better fit this scenario, keeping costs as low as possible?

A. Use RDS Multi-AZ with two tables, one for -Active calls" and one for -Terminated ca Ils". In this way the "Active caIIs_ table is always small and effective to access.

B. Use DynamoDB with a "Calls" table and a Global Secondary Index on a "IsActive"' attribute that is present for active calls only In this way the Global Secondary index is sparse and more effective.

C. Use DynamoDB with a 'Calls" table and a Global secondary index on a 'State" attribute that can equal to "active" or "terminated" in this way the Global Secondary index can be used for all Items in the table.

D. Use RDS Multi-AZ with a "CALLS" table and an Indexed "STATE* field that can be equal to 'ACTIVE" or -TERMNATED" In this way the SOL query Is optimized by the use of the Index.

Q9. You have deployed a three-tier web application in a VPC with a CIOR block of 10 0 0 0/ 28 You initially deploy two web servers, two application sewers, two database sewers and one NAT instance tor a total   of seven EC2 instances The web. Application and database servers are deployed across two availability zones (AZs). You also deploy an ELB in front of the two web sewers, and use Route53 for DN5 Web (raffile gradually increases in the first few days following the deployment, so you attempt to double the number of instances in each tier of the application to handle the new load unfortunately some of these new instances fail to launch.

Which of the following could De the root caused? (Choose 2 answers)

A. AW5 resewes the first and the last private IP address in each subnet's CIDR block so you do not have enough addresses left to launch all of the new EC2 instances

B. The Internet Gateway (IGW) of your VPC has scaled-up, adding more instances to handle the traffic spike, reducing the number of available private IP addresses for new instance launches

C. The ELB has scaled-up, adding more instances to handle the traffic spike, reducing the number of available private IP addresses for new instance launches

D. AW5 reserves one IP address in each subnet's CIDR block for Route53 so you do not have enough addresses left to launch all of the new EC2 instances

E. AW5 reserves the first four and the last IP address in each subnet's CIDR block so you do not have

enough addresses left to launch all of the new EC2 instances
