Question#251

A solutions architect needs to design a network that will allow multiple Amazon EC2 instances to access a common data source used for mission-critical data that can be accessed by all the EC2 instances simultaneously. The solution must be highly scalable, easy to implement and support the NFS protocol.
Which solution meets these requirements?

  • A. Create an Amazon EFS file system. Configure a mount target in each Availability Zone. Attach each instance to the appropriate mount target.
  • B. Create an additional EC2 instance and configure it as a file server. Create a security group that allows communication between the instances and apply that to the additional instance.
  • C. Create an Amazon S3 bucket with the appropriate permissions. Create a role in AWS IAM that grants the correct permissions to the S3 bucket. Attach the role to the EC2 instances that need access to the data.
  • D. Create an Amazon EBS volume with the appropriate permissions. Create a role in AWS IAM that grants the correct permissions to the EBS volume. Attach the role to the EC2 instances that need access to the data.

Question#252

A company hosts its application using Amazon Elastic Container Service (Amazon ECS) and wants to ensure high availability. The company wants to be able to deploy updates to its application even if nodes in one Availability Zone are not accessible.
The expected request volume for the application is 100 requests per second, and each container task is able to serve at least 60 requests per second. The company set up Amazon ECS with a rolling update deployment type with the minimum healthy percent parameter set to 50% and the maximum percent set to
100%.
Which configuration of tasks and Availability Zones meets these requirements?

  • A. Deploy the application across two Availability Zones, with one task in each Availability Zone.
  • B. Deploy the application across two Availability Zones, with two tasks in each Availability Zone.
  • C. Deploy the application across three Availability Zones, with one task in each Availability Zone.
  • D. Deploy the application across three Availability Zones, with two tasks in each Availability Zone.

  • A. Set an overall password policy for the entire AWS account
  • B. Set a password policy for each IAM user in the AWS account.
  • C. Use third-party vendor software to set password requirements.
  • D. Attach an Amazon CloudWatch rule to the Create_newuser event to set the password with the appropriate requirements.

Question#254

A company wants to improve the availability and performance of its hybrid application. The application consists of a stateful TCP-based workload hosted on
Amazon EC2 instances in different AWS Regions and a stateless UOP-based workload hosted on premises.
Which combination of actions should a solutions architect take to improve availability and performance? (Choose two.)

  • A. Create an accelerator using AWS Global Accelerator. Add the load balancers as endpoints.
  • B. Create an Amazon CloudFront distribution with an origin that uses Amazon Route 53 latency-based routing to route requests to the load balancers.
  • C. Configure two Application Load Balancers in each Region. The first will route to the EC2 endpoints and the second will route to the on-premises endpoints.
  • D. Configure a Network Load Balancer in each Region to address the EC2 endpoints. Configure a Network Load Balancer in each Region that routes to the on- premises endpoints.
  • E. Configure a Network Load Balancer in each Region to address the EC2 endpoints. Configure an Application Load Balancer in each Region that routes to the on-premises endpoints

Question#255

A solutions architect is designing the architecture of a new application being deployed to the AWS Cloud. The application will run on Amazon EC2 On-Demand
Instances and will automatically scale across multiple Availability Zones. The EC2 instances will scale up and down frequently throughout the day. An Application
Load Balancer (ALB) will handle the load distribution. The architecture needs to support distributed session data management. The company is willing to make changes to code if needed.
What should the solutions architect do to ensure that the architecture supports distributed session data management?

  • A. Use Amazon ElastiCache to manage and store session data.
  • B. Use session affinity (sticky sessions) of the ALB to manage session data.
  • C. Use Session Manager from AWS Systems Manager to manage the session.
  • D. Use the GetSessionToken API operation in AWS Security Token Service (AWS STS) to manage the session.

Question#256

A company has an ecommerce application running in a single VPC. The application stack has a single web server and an Amazon RDS Multi-AZ DB instance.
The company launches new products twice a month. This increases website traffic by approximately 400% for a minimum of 72 hours. During product launches, users experience slow response times and frequent timeout errors in their browsers.
What should a solutions architect do to mitigate the slow response times and timeout errors while minimizing operational overhead?

  • A. Increase the instance size of the web server.
  • B. Add an Application Load Balancer and an additional web server.
  • C. Add Amazon EC2 Auto Scaling and an Application Load Balancer.
  • D. Deploy an Amazon ElastiCache cluster to store frequently accessed data.

Question#257

A solutions architect is designing an architecture to run a third-party database server. The database software is memory intensive and has a CPU-based licensing model where the cost increases with the number of vCPU cores within the operating system. The solutions architect must select an Amazon EC2 instance with sufficient memory to run the database software, but the selected instance has a large number of vCPUs. The solutions architect must ensure that the vCPUs will not be underutilized and must minimize costs.
Which solution meets these requirements?

  • A. Select and launch a smaller EC2 instance with an appropriate number of vCPUs.
  • B. Configure the CPU cores and threads on the selected EC2 instance during instance launch.
  • C. Create a new EC2 instance and ensure multithreading is enabled when configuring the instance details.
  • D. Create a new Capacity Reservation and select the appropriate instance type. Launch the instance into this new Capacity Reservation.

Question#258

A company receives 10 TB of instrumentation data each day from several machines located at a single factory. The data consists of JSON files stored on a storage area network (SAN) in an on-premises data center located within the factory. The company wants to send this data to Amazon S3 where it can be accessed by several additional systems that provide critical near-real-lime analytics. A secure transfer is important because the data is considered sensitive.
Which solution offers the MOST reliable data transfer?

  • A. AWS DataSync over public internet
  • B. AWS DataSync over AWS Direct Connect
  • C. AWS Database Migration Service (AWS DMS) over public internet
  • D. AWS Database Migration Service (AWS DMS) over AWS Direct Connect

✑ Retain all the images
✑ Incur no cost for retrieval.
✑ Have minimal management overhead.
✑ Have the images available with no impact on retrieval time.
Which solution meets these requirements?

  • A. Implement S3 Intelligent-Tiering
  • B. Implement S3 storage class analysis
  • C. Implement an S3 Lifecycle policy to move data to S3 Standard-Infrequent Access (S3 Standard-IA).
  • D. Implement an S3 Lifecycle policy to move data to S3 One Zone-Infrequent Access (S3 One Zone-IA).

Question#260

A company hosts more than 300 global websites and applications. The company requires a platform to analyze more than 30 TB of clickstream data each day.

  • B. Create an Auto Scaling group of Amazon EC2 instances to process the data and send it to an Amazon S3 data lake for Amazon Redshift to use for analysis.
  • C. Cache the data to Amazon CloudFront. Store the data in an Amazon S3 bucket. When an object is added to the S3 bucket, run an AWS Lambda function to process the data for analysis.
  • D. Collect the data from Amazon Kinesis Data Streams. Use Amazon Kinesis Data Firehose to transmit the data to an Amazon S3 data lake. Load the data in Amazon Redshift for analysis.
