The engineering team at a healthcare company is working on the Disaster Recovery (DR) plans for its Redshift cluster deployed in the eu-west-1 Region. The existing cluster is encrypted via AWS KMS and the team wants to copy the Redshift snapshots to another Region to meet the DR requirements.
As a Solutions Architect Professional, which of the following solutions would you suggest to address the given use-case?
A leading internet television network company uses AWS Cloud for analytics, recommendation engines and video transcoding. To monitor and optimize this network, the engineering team at the company has developed a solution for ingesting, augmenting, and analyzing the multiple terabytes of data its network generates daily in the form of virtual private cloud (VPC) flow logs. This would enable the company to identify performance-improvement opportunities such as identifying apps that are communicating across regions and collocating them. The VPC flow logs data is funneled into Kinesis Data Streams which further acts as the source of a delivery stream for Kinesis Firehose. The engineering team has now configured a Kinesis Agent to send the VPC flow logs data from another set of network devices to the same Firehose delivery stream. They noticed that data is not reaching Firehose as expected.
As a Solutions Architect Professional, which of the following options would you identify as the MOST plausible root cause behind this issue?
A solo entrepreneur is working on a new digital media startup and wants to have a hands-on understanding of the comparative pricing for various storage types available on AWS Cloud. The entrepreneur has created a test file of size 5 GB with some random data. Next, he uploads this test file into AWS S3 Standard storage class, provisions an EBS volume (General Purpose SSD (gp2)) with 50 GB of provisioned storage and copies the test file into the EBS volume, and lastly copies the test file into an EFS Standard Storage filesystem. At the end of the month, he analyses the bill for costs incurred on the respective storage types for the test file.
What of the following represents the correct order of the storage charges incurred for the test file on these three storage types?
A social media company has its corporate headquarters in New York with an on-premises data center using an AWS Direct Connect connection to the AWS VPC. The branch offices in San Francisco and Miami use Site-to-Site VPN connections to connect to the AWS VPC. The company is looking for a solution to have the branch offices send and receive data with each other as well as with their corporate headquarters.

A Big Data Analytics company has built a custom data warehousing solution for a large airline by using Amazon Redshift. The solution helps the airline to analyze the international and domestic flight reservations, ticket issuing and boarding information, aircraft operation records, and cargo transportation records. As part of the cost optimizations, the airline now wants to move any historical data (any data older than a year) into S3, as the daily analytical reports consume data for just the last one year. However, the analysts at multiple divisions of the airline want to retain the ability to cross-reference this historical data along with the daily reports. The airline wants to develop a solution with the LEAST amount of effort and MINIMUM cost.

A web development studio runs hundreds of Proof-of-Concept (PoC) and demo applications on virtual machines running on an on-premises server. Many of the applications are simple PHP, JavaScript or Python web applications which are no longer actively developed and serve little traffic.
As a Solutions Architect Professional, which of the following approaches would you suggest to migrate these applications to AWS with the LOWEST infrastructure cost?
The DevOps team at a financial services company has provisioned a new GPU optimized EC2 instance X by choosing the default security group of the default VPC. The team can ping instance X from other instances in the VPC. The other instances were also created using the default security group. The next day, the team launches another GPU optimized instance Y by creating a new security group and attaching it to instance Y. All other configuration options for instance Y are chosen as default. However, the team is not able to ping instance Y from other instances in the VPC.

A stock trading firm uses AWS Cloud for its IT infrastructure. The firm runs several trading-risk simulation applications, developing complex algorithms to simulate diverse scenarios in order to evaluate the financial health of its customers. The firm stores customers' financial records on Amazon S3. The engineering team needs to implement an archival solution based on Amazon S3 Glacier to enforce regulatory and compliance controls on data access.

A digital marketing company uses S3 to store artifacts that may only be accessible to EC2 instances running in a private VPC. The security team at the company is apprehensive about an attack vector wherein any team member with access to this instance could also set up an EC2 instance in another VPC to access these artifacts.
As an AWS Certified Solutions Architect Professional, which of the following solutions will you recommend to prevent such unauthorized access to the artifacts in S3?
A leading club in the Major League Baseball runs a web platform that boasts over 50,000 pages and over 100 million digitized photographs. It is available in six languages and maintains up-to-date information for the season. The engineering team has built a notification system on the web platform using SNS notifications which are then handled by a Lambda function for end-user delivery. During the off-season, the notification systems need to handle about 100 requests per second. During the peak baseball season, the rate touches about 5000 requests per second and it is noticed that a significant number of the notifications are not being delivered to the end-users on the web platform.
As a Solutions Architect Professional, which of the following would you suggest as the BEST fit solution to address this issue?
