A multimedia company needs to deliver its video-on-demand (VOD) content to its subscribers in a cost-effective way. The video files range in size from 1-15 GB and are typically viewed frequently for the first 6 months after creation, and then access decreases considerably. The company requires all video files to remain immediately available for subscribers. There are now roughly 30,000 files, and the company anticipates doubling that number over time.
What is the MOST cost-effective solution for delivering the company's VOD content?
A. Store the video files in an Amazon S3 bucket using S3 Intelligent-Tiering. Use Amazon CloudFront to deliver the content with the S3 bucket as the origin.A company runs a legacy system on a single m4.2xlarge Amazon EC2 instance with Amazon EBS storage. The EC2 instance runs both the web server and a self-managed Oracle database. A snapshot is made of the EBS volume every 12
hours, and an AMI was created from the fully configured EC2 instance.
A recent event that terminated the EC2 instance led to several hours of downtime. The application was successfully launched from the AMI, but the age of the EBS snapshot and the repair of the database resulted in the loss of 8 hours of
data. The system was also down for 4 hours while the Systems Operators manually performed these processes.
What architectural changes will minimize downtime and reduce the chance of lost data?
A. Create an Amazon CloudWatch alarm to automatically recover the instance. Create a script that will check and repair the database upon reboot. Subscribe the Operations team to the Amazon SNS message generated by the CloudWatch alarm.You are implementing a URL whitelisting system for a company that wants to restrict outbound HTTP'S connections to specific domains from their EC2-hosted applications. You deploy a single EC2 instance running proxy software and configure It to accept traffic from all subnets and EC2 instances in the VPC. You configure the proxy to only pass through traffic to domains that you define in its whitelist configuration. You have a nightly maintenance window or 10 minutes where all instances fetch new software updates. Each update Is about 200MB In size and there are 500 instances In the VPC that routinely fetch updates. After a few days you notice that some machines are failing to successfully download some, but not all of their updates within the maintenance window. The download URLs used for these updates are correctly listed in the proxy's whitelist configuration and you are able to access them manually using a web browser on the instances.
What might be happening? (Choose two.)
A. You are running the proxy on an undersized EC2 instance type so network throughput is not sufficient for all instances to download their updates in time.A company has a web service deployed in the following two AWS Regions: us-west-2 and us-est-1. Each AWS region runs an identical version of the web service. Amazon Route 53 is used to route customers to the AWS Region that has the lowest latency.
The company wants to improve the availability of the web service in case an outage occurs in one of the two AWS Regions.
A Solutions Architect has recommended that a Route 53 health check be performed. The health check must detect a specific text on an endpoint.
What combination of conditions should the endpoint meet to pass the Route 53 health check? (Choose two.)
A. The endpoint must establish a TCP connection within 10 seconds.You control access to S3 buckets and objects with:
A. Identity and Access Management (IAM) Policies.A company experienced a breach of highly confidential personal information due to permission issues on an Amazon S3 bucket. The Information Security team has tightened the bucket policy to restrict access. Additionally, to be better prepared for future attacks, these requirements must be met:
1.
Identify remote IP addresses that are accessing the bucket objects.
2.
Receive alerts when the security policy on the bucket is changed.
3.
Remediate the policy changes automatically. Which strategies should the Solutions Architect use?
A. Use Amazon CloudWatch Logs with CloudWatch filters to identify remote IP addresses. Use CloudWatch Events rules with AWS Lambda to automatically remediate S3 bucket policy changes. Use Amazon SES with CloudWatch Events rules for alerts.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. CloudFront to serve HLS transcoded videos from EC2.A company is migrating its on-premises build artifact server to an AWS solution. The current system consists of an Apache HTTP server that serves artifacts to clients on the local network, restricted by the perimeter firewall. The artifact consumers are largely build automation scripts that download artifacts via anonymous HTTP, which the company will be unable to modify within its migration timetable.
The company decides to move the solution to Amazon S3 static website hosting. The artifact consumers will be migrated to Amazon EC2 instances located within both public and private subnets in a virtual private cloud (VPC).
Which solution will permit the artifact consumers to download artifacts without modifying the existing automation scripts?
A. Create a NAT gateway within a public subnet of the VPC. Add a default route pointing to the NAT gateway into the route table associated with the subnets containing consumers. Configure the bucket policy to allow the s3:ListBucket and s3:GetObject actions using the condition IpAddress and the condition key aws:SourceIp matching the elastic IP address of the NAT gateway.A company had a tight deadline to migrate its on-premises environment to AWS. It moved over Microsoft SQL Servers and Microsoft Windows Servers using the virtual machine import/export service and rebuild other applications native to the cloud. The team created both Amazon EC2 databases and used Amazon RDS. Each team in the company was responsible for migrating their applications, and they have created individual accounts for isolation of resources. The company did not have much time to consider costs, but now it would like suggestions on reducing its AWS spend.
Which steps should a Solutions Architect take to reduce costs?
A. Enable AWS Business Support and review AWS Trusted Advisor's cost checks. Create Amazon EC2 Auto Scaling groups for applications that experience fluctuating demand. Save AWS Simple Monthly Calculator reports in Amazon S3 for trend analysis. Create a master account under Organizations and have teams join for consolidated billing.A large real-estate brokerage is exploring the option of adding a cost-effective location based alert to their existing mobile application. The application backend infrastructure currently runs on AWS. Users who opt in to this service will receive
alerts on their mobile device regarding real-estate otters in proximity to their location. For the alerts to be relevant delivery time needs to be in the low minute count the existing mobile app has 5 million users across the US.
Which one of the following architectural suggestions would you make to the customer?
A. The mobile application will submit its location to a web service endpoint utilizing Elastic Load Balancing and EC2 instances; DynamoDB will be used to store and retrieve relevant offers EC2 instances will communicate with mobile earners/ device providers to push alerts back to mobile application.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
