Question1: A company has several Amazon EC2 instances to both public and private subnets within a VPC that is not connected to the corporate network. A security group associated with the EC2 instances allows the company to use the Windows remote desktop protocol (RDP) over the internet to access the instances. The security team has noticed connection attempts from unknown sources. The company wants to implement a more secure solution to access the EC2 instances.
Which strategy should a solutions architect implement?

Question2: A development team has created a new flight tracker application that provides near-real-time data to users. The application has a front end that consists of an Applicate Load Balancer (ALB) in front of two large Amazon EC2 instances in a single Availability Zone. Data is stored in a single Amazon RDS MySQL DB instance. An Amazon Route 53 DNS record points to the ALB.
Management wants the development team to improve the solution to achieve maximum reliability with the least amount of operational overhead.
Which set of actions should the team take?

Company Developers deploy changes to the application frequently. The framework installation is becoming a bottleneck in this process.
Which of the following would speed up this process?

Question4: A utility company wants to collect usage data every 5 minutes from its smart meters to facilitate time-of-use metering When a meter sends data to AWS the data is sent to Amazon API Gateway, processed by an AWS Lambda function and stored in an Amazon DynamoDB table During the pilot phase, the Lambda functions took from 3 to 5 seconds to complete As more smart meters are deployed, the Engineers notice the Lambda functions are taking from 1 to 2 minutes to complete The functions are also increasing in duration as new types of metrics are collected from the devices There are many ProvisionedThroughputExceededException errors while performing PUT operations on DynamoDB and there are also many TooMany Requests Exception errors from Lambda.
Which combination of changes will resolve these issues? (Select TWO )

Question5: A developer reports receiving an Error 403: Access Denied message when they try to download an object from an Amazon S3 bucket. The S3 bucket is accessed using an S3 endpoint inside a VPC, and is encrypted with an AWS KMS key.

Question14: A company runs a video processing platform. Files are uploaded by users who connect to a web server, which stores them on an Amazon EFS share. This web server is running on a single Amazon EC2 instance. A different group of instances, running in an Auto Scaling group, scans the EFS share directory structure for new files to process and generates new videos (thumbnails, different resolution, compression, etc.) according to the instructions file, which is uploaded along with the video files. A different application running on a group of instances managed by an Auto Scaling group processes the video files and then deletes them from the EFS share. The results are stored in an S3 bucket. Links to the processed video files are emailed to the customer.
The company has recently discovered that as they add more instances to the Auto Scaling Group, many files are processed twice, so image processing speed is not improved. The maximum size of these video files is
2GB.

Which solution will be MOST cost effective while maintaining reliability?

Question16: A company runs a legacy system on a single m4.2xlarge Amazon EC2 instance with Amazon EBS2 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?

(Select TWO)

Question19: A company currently has data hosted in an IBM Db2 database A web application calls an API that runs stored procedures on the database to retrieve user information data that is read-only. This data is historical in nature and changes on a daily basis. When a user logs in to the application, this data needs to be retrieved within 3 seconds. Each time a user logs in. the stored procedures run. Users log in several times a day to check stock prices.
Running this database has become cost-prohibitive due to Db2 CPU licensing. Performance goals are not being met. Timeouts from Db2 are common due to long-running queries Which approach should a solutions architect take to migrate this solution to AWS?

Question33: A company is migrating a subset of its application APIs from Amazon EC2 instances to run on a serverless infrastructure. The company has set up Amazon API Gateway, AWS Lambda, and Amazon DynamoDB for the new application. The primary responsibility of the Lambda function is to obtain data from a third-party Software as a Service (SaaS) provider. For consistency, the Lambda function is attached to the same virtual private cloud (VPC) as the original EC2 instances.

What should the solutions architect do to deploy the CloudFormation StackSets in all AWS accounts?

Question36: A company is adding a new approved external vendor that only supports IPv6 connectivity. The company's backend systems sit in the private subnet of an Amazon VPC. The company uses a NAT gateway to allow these systems to communicate with external vendors over IPv4. Company policy requires systems that communicate with external vendors use a security group that limits access to only approved external vendors.
The virtual private cloud (VPC) uses the default network ACL.
The Systems Operator successfully assigns IPv6 addresses to each of the backend systems. The Systems Operator also updates the outbound security group to include the IPv6 CIDR of the external vendor (destination).

Question71: A company runs a memory-intensive analytics application using on-demand Amazon EC2 compute optimized instance. The application is used continuously and application demand doubles during working hours. The application currently scales based on CPU usage. When scaling in occurs, a lifecycle hook is used because the instance requires 4 minutes to clean the application state before terminating.
Because users reported poor performance during working hours, scheduled scaling actions were implemented so additional instances would be added during working hours. The Solutions Architect has been asked to reduce the cost of the application.
Which solution is MOST cost-effective?

Question72: A large company recently experienced an unexpected increase in Amazon RDS and Amazon DynamoDB costs. The company needs to increase visibility into delays of AWS Billing and Cost Management.

Question77: An organization has a write-intensive mobile application that uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. The application has scaled well, however, costs have increased exponentially because of higher than anticipated Lambda costs. The application's use is unpredictable, but there has been a steady 20% increase in utilization every month.
While monitoring the current Lambda functions, the Solutions Architect notices that the execution-time averages 4.5 minutes. Most of the wait time is the result of a high-latency network call to a 3-TB MySQL database server that is on-premises. A VPN is used to connect to the VPC, so the Lambda functions have been configured with a five-minute timeout.
How can the Solutions Architect reduce the cost of the current architecture?

Question87: A healthcare company runs a production workload on AWS that stores highly sensitive personal information.
The security team mandates that, for auditing purposes, any AWS API action using AWS account root user credentials must automatically create a high-priority ticket in the company's ticketing system. The ticketing system has a monthly 3-hour maintenance window when no tickets can be created.
To meet security requirements, the company enabled AWS CloudTrail logs and wrote a scheduled AWSLambda function that uses Amazon Athena to query API actions performed by the root user. The Lambda function submits any actions found to the ticketing system API.
