Question1: A company wants to move a web application to AWS. The application stores session information locally on each web server, which will make auto scaling difficult. As part of the migration, the application will be rewritten to decouple the session data from the web servers. The company requires low latency, scalability, and availability.
Which service will meet the requirements for storing the session information in the MOST cost-effective way?

Question2: A company with multiple accounts is currently using a configuration that does not meet the following security governance policies
* Prevent ingress from port 22 to any Amazon EC2 instance
* Require billing and application tags for resources
* Encrypt all Amazon EBS volumes
A Solutions Architect wants to provide preventive and detective controls including notifications about a specific resource, if there are policy deviations.
Which solution should the Solutions Architect implement?

Question3: A company is migrating an application to AWS. It wants to use fully managed services as much as possible during the migration. The company needs to store large, important documents within the application with the following requirements:
* The data must be highly durable and available.
* The data must always be encrypted at rest and in transit.
* The encryption key must be managed by the company and rotated periodically.
Which of the following solutions should the Solutions Architect recommend?

Question4: A company uses an Amazon EMR cluster to process data once a day. The raw data comes from Amazon S3, and the resulting processed data is also stored in Amazon S3. The processing must complete within 4 hours; currently, it only takes 3 hours. However, the processing time is taking 5 to 10 minutes. longer each week due to an increasing volume of raw data.
The team is also concerned about rising costs as the compute capacity increases. The EMR cluster is currently running on three m3.xlarge instances (one master and two core nodes).
Which of the following solutions will reduce costs related to the increasing compute needs?

Question5: 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?

Question6: A company runs its containerized batch jobs on Amazon ECS. The jobs are scheduled by submitting a container image, a task definition, and the relevant data to an Amazon S3 bucket. Container images may be unique per job. Running the jobs as quickly as possible is of utmost importance, so submitting jobs artifacts to the S3 bucket triggers the job to run immediately. Sometimes there may no jobs running at all. However, jobs of any size can be submitted with no prior warning to the IT Operations team. Job definitions include CPU and memory resource requirements.
What solution will allow the batch jobs to complete as quickly as possible after being scheduled?

Question7: A company that provides wireless services needs a solution to store and analyze log files about user activities.
Currently, log files are delivered daily to Amazon Linux on Amazon EC2 instance. A batch script is run once a day to aggregate data used for analysis by a third-party tool. The data pushed to the third-party tool is used to generate a visualization for end users. The batch script is cumbersome to maintain, and it takes several hours to deliver the ever-increasing data volumes to the third-party tool. The company wants to lower costs, and is open to considering a new tool that minimizes development effort and lowers administrative overhead. The company wants to build a more agile solution that can store and perform the analysis in near-real time, with minimal overhead. The solution needs to be cost effective and scalable to meet the company's end-user base growth.

The web application requires user authorization and session tracking for dynamic content. The CloudFront distribution has a single cache behavior configured to forward the Authorization, Host, and User-Agent HTTP whitelist headers and a session cookie to the origin. All other cache behavior settings are set to their default value.
A valid ACM certificate is applied to the CloudFront distribution with a matching CNAME in the distribution settings. The ACM certificate is also applied to the HTTPS listener for the Application Load Balancer. The CloudFront origin protocol policy is set to HTTPS only. Analysis of the cache statistics report shows that the miss rate for this distribution is very high.
What can the Solutions Architect do to improve the cache hit rate for this distribution without causing the SSL/TLS handshake between CloudFront and the Application Load Balancer to fail?

Question69: A company's application is increasingly popular and experiencing latency because of high volume reads on the database server.
The service has the following properties:
* A highly available REST API hosted in one region using Application Load Balancer (ALB) with auto scaling.
* A MySQL database hosted on an Amazon EC2 instance in a single Availability Zone.
The company wants to reduce latency, increase in-region database read performance, and have multi-region disaster recovery capabilities that can perform a live recovery automatically without any data or performance loss (HA/DR).
Which deployment strategy will meet these requirements?

Question70: A company wants to manage the costs associated with a group of 20 applications that are critical, by migrating to AWS. The applications are a mix of Java and Node.js spread across different instance clusters. The company wants to minimize costs while standardizing by using a single deployment methodology. Most of the applications are part of month-end processing routines with a small number of concurrent users, but they are occasionally run at other times. Average application memory consumption is less than 1 GB, though some applications use as much as 2.5 GB of memory during peak processing. The most important application in the group is a billing report written in Java that accesses multiple data sources and often for several hours.
Which is the MOST cost-effective solution?

Question71: 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?

Question72: A retail company is running an application that stores invoice files in Amazon S3 bucket and metadata about the files in an Amazon. The S3 bucket and DynamoDB table are in us-east-1. The company wants to protect itself from data corruption and loss of connectivity to either Region.
Which option meets these requirements?

Question73: A company's data center is connected to the AWS Cloud over a minimally used 10-Gbps AWS Direct Connect connection with a private virtual interface to its virtual private cloud {VPC) The company internet connection is 200 Mbps and the company has a 150-TB dataset that is created each Friday The data must be transferred and available in Amazon S3 on Monday morning Which is the LEAST expensive way to meet the requirements while allowing for data transfer growth?

Question74: A company is migrating its on-premises systems to AWS. The user environment consists of the following systems:
* Windows and Linux virtual machines running on VMware.
* Physical servers running Red Hat Enterprise Linux.
The company wants to be able to perform the following steps before migrating to AWS:
* Identify dependencies between on-premises systems.
* Group systems together into applications to build migration plans.
* Review performance data using Amazon Athena to ensure that Amazon EC2 instances are right-sized.
How can these requirements be met?

Question75: A Solutions Architect is migrating a 10 TB PostgreSQL database to Amazon RDS for PostgreSQL. The company's internet link is 50 MB with a VPN in the Amazon VPC, and the Solutions Architect needs to migrate the data and synchronize the changes before the cutover. The cutover must take place within an 8-day period.
What is the LEAST complex method of migrating the database securely and reliably?
