A new application is running on Amazon Elastic Container Service (Amazon ECS) with AWS Fargate The application uses an Amazon Aurora MySQL database The application and the database run m the same subnets of a VPC with distinct security groups that are configured.
The password (or the database is stored m AWS Secrets Manager and is passed to the application through the D8_PASSWORD environment variable The hostname of the database is passed to the application through the DB_HOST environment variable The application Is failing to access the database.
Which combination of actions should a solutions architect take to resolve this error? (Select THREE )
A. Ensure that the container has the environment variable with name "DB_PASSWORD" specified with a "ValueFrom" and the ARN of the secretYour company is storing millions of sensitive transactions across thousands of 100-GB files that must be encrypted in transit and at rest. Analysts concurrently depend on subsets of files, which can consume up to 5 TB of space, to generate
simulations that can be used to steer business decisions.
You are required to design an AWS solution that can cost effectively accommodate the long-term storage and in-flight subsets of data.
Which approach can satisfy these objectives?
A. Use Amazon Simple Storage Service (S3) with server-side encryption, and run simulations on subsets in ephemeral drives on Amazon EC2.A company is currently running a production workload on AWS that is very I/O intensive. Its workload consists of a single tier with 10 c4.8xlarge instances, each with 2 TB gp2 volumes. The number of processing jobs has recently increased, and latency has increased as well. The team realizes that they are constrained on the IOPS. For the application to perform efficiently, they need to increase the IOPS by 3,000 for each of the instances.
Which of the following designs will meet the performance goal MOST cost effectively?
A. Change the type of Amazon EBS volume from gp2 to io1 and set provisioned IOPS to 9,000.You have set up Auto Scaling to automatically scale in. Consequently, you must decide which instances Auto Scaling should end first. What should you use to configure this?
A. An Elastic Load BalancerAn organization has two Amazon EC2 instances:
1.
The first is running an ordering application and an inventory application.
2.
The second is running a queuing system.
During certain times of the year, several thousand orders are placed per second. Some orders were lost when the queuing system was down. Also, the organization's inventory application has the incorrect quantity of products because some orders were processed twice.
What should be done to ensure that the applications can handle the increasing number of orders?
A. Put the ordering and inventory applications into their own AWS Lambda functions. Have the ordering application write the messages into an Amazon SQS FIFO queue.IAM Secure and Scalable is an organization which provides scalable and secure SAAS to its clients. They are planning to host a web server and App server on AWS VPC as separate tiers. The organization wants to implement the scalability by configuring Auto Scaling and load balancer with their app servers (middle tier) too.
Which of the below mentioned options suits their requirements?
A. Since ELB is internet facing, it is recommended to setup HAProxy as the Load balancer within the VPC.A bank is designing an online customer service portal where customers can chat with customer service agents. The portal is required to maintain a 15-minute RPO or RTO in case of a regional disaster. Banking regulations require that all customer service chat transcripts must be preserved on durable storage for at least 7 years, chat conversations must be encrypted in-flight, and transcripts must be encrypted at rest. The Data Loss Prevention team requires that data at rest must be encrypted using a key that the team controls, rotates, and revokes.
Which design meets these requirements?
A. The chat application logs each chat message into Amazon CloudWatch Logs. A scheduled AWS Lambda function invokes a CloudWatch Logs CreateExportTask every 5 minutes to export chat transcripts to Amazon S3. The S3 bucket is configured for cross-region replication to the backup region. Separate AWS KMS keys are specified for the CloudWatch Logs group and the S3 bucket.You deployed your company website using Elastic Beanstalk and you enabled log file rotation to S3. An Elastic Map Reduce job is periodically analyzing the logs on S3 to build a usage dashboard that you share with your CIO. You recently improved overall performance of the website using Cloud Front for dynamic content delivery and your website as the origin. After this architectural change, the usage dashboard shows that the traffic on your website dropped by an order of magnitude.
How do you fix your usage dashboard?
A. Enable Cloud Front to deliver access logs to S3 and use them as input of the Elastic Map Reduce job.A solutions architect is troubleshooting an application that runs on Amazon EC2 instances. The EC2 instances run in an Auto Scaling group. The application needs to access user data in an Amazon DynamoDB table that has fixed
provisioned capacity. To match the increased workload, the solutions architect recently doubled the maximum size of the Auto Scaling group. Now, when many instances launch at the same time, some application components are throttled when the components scan the DynamoDB table. The Auto Scaling group terminates the failing instances and starts new instances until all applications are running
A solutions architect must implement a solution to mitigate the throttling issue in the MOST cost-effective manner Which solution will meet these requirements?
A. Double the provisioned read capacity of the DynamoDB table.If you have a running instance using an Amazon EBS boot partition, you can call the _______ API to release the compute resources but preserve the data on the boot partition.
A. Stop InstancesNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job. But how to prepare for the exam effectively?
