A global media company is using Amazon CloudFront to deliver media-rich content to its audience across the world. The Content Delivery Network (CDN) offers a multi-tier cache by default, with regional edge caches that improve latency and lower the load on the origin servers when the object is not already cached at the edge. However there are certain content types that bypass the regional edge cache, and go directly to the origin. Which of the following content types skip the regional edge cache? (Select two)
A leading video streaming service delivers billions of hours of content from Amazon S3 to customers around the world. Amazon S3 also serves as the data lake for its big data analytics solution.

Which of the following is the MOST cost-effective strategy for storing this intermediary query data?
A technology blogger wants to write a review on the comparative pricing for various storage types available on AWS Cloud. The blogger has created a test file of size 1GB with some random data. Next he copies this test file into AWS S3 Standard storage class, provisions an EBS volume (General Purpose SSD (gp2)) with 100GB 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 is the correct order of the storage charges incurred for the test file on these three storage types?

A social photo-sharing company uses Amazon S3 to store the images uploaded by the users. These images are kept encrypted in S3 by using AWS-KMS and the company manages its own Customer Master Key (CMK) for encryption. A member of the DevOps team accidentally deleted the CMK a day ago, thereby rendering the user's photo data unrecoverable. You have been contacted by the company to consult them on possible solutions to this crisis. As a solutions architect, which of the following steps would you recommend to solve this issue?
A major bank is using SQS to migrate several core banking applications to the cloud to ensure high availability and cost efficiency while simplifying administrative complexity and overhead. The development team at the bank expects a peak rate of about 1000 messages per second to be processed via SQS. It is important that the messages are processed in order. Which of the following options can be used to implement this system?
The solo founder at a tech startup has just created a brand new AWS account. The founder has provisioned an EC2 instance 1A which is running in region A. Later, he takes a snapshot of the instance 1A and then creates a new AMI in region A from this snapshot. This AMI is then copied into another region B. The founder provisions an instance 1B in region B using this new AMI in region B. At this point in time, what entities exist in region B?
A large financial institution operates an on-premises data center with hundreds of PB of data managed on Microsoft’s Distributed File System (DFS). The CTO wants the organization to transition into a hybrid cloud environment and run data-intensive analytics workloads that support DFS. Which of the following AWS services can facilitate the migration of these workloads?
A gaming company uses Amazon Aurora as its primary database service. The company has now deployed 5 multi-AZ read replicas to increase the read throughput and for use as failover target. The replicas have been assigned the following failover priority tiers and corresponding sizes are given in parentheses: tier-1 (16TB), tier-1 (32TB), tier-10 (16TB), tier-15 (16TB), tier-15 (32TB). In the event of a failover, Amazon RDS will promote which of the following read replicas?
A social media analytics company uses a fleet of EC2 servers to manage its analytics workflow. These EC2 servers operate under an Auto Scaling group. The engineers at the company want to be able to download log files whenever an instance terminates because of a scale-in event from an auto-scaling policy. Which of the following features can be used to enable this custom action?
A US-based healthcare startup is building an interactive diagnostic tool for COVID-19 related assessments. The users would be required to capture their personal health records via this tool. As this is sensitive health information, the backup of the user data must be kept encrypted in S3. The startup does not want to provide its own encryption keys but still wants to maintain an audit trail of when an encryption key was used and by whom. Which of the following is the BEST solution for this use-case?
A biotechnology company wants to seamlessly integrate its on-premises data center with AWS cloud-based IT systems which would be critical to manage as well as scale-up the complex planning and execution of every stage of its drug development process. As part of a pilot program, the company wants to integrate data files from its analytical instruments into AWS via an NFS interface. Which of the following AWS service is the MOST efficient solution for the given use-case?
An IT Company wants to move all the compute components of its AWS Cloud infrastructure into serverless architecture. Their development stack comprises a mix of backend programming languages and the company would like to explore the support offered by the AWS Lambda runtime for their programming languages stack. Can you identify the programming languages supported by the Lambda runtime? (Select two)
A silicon valley based research group is working on a High Performance Computing (HPC) application in the area of Computational Fluid Dynamics. The application carries out simulations of the external aerodynamics around a car and needs to be deployed on EC2 instances with a requirement for high levels of inter-node communications and high network traffic between the instances. As a solutions architect, which of the following options would you recommend to the engineering team at the startup? (Select two)
A research group at an ivy-league university needs a fleet of EC2 instances operating in a fault-tolerant architecture for a specialized task that must deliver high random I/O performance. Each instance in the fleet would have access to a dataset that is replicated across the instances. Because of the resilient architecture, the specialized task would continue to be processed even if any of the instances goes down as the underlying application architecture would ensure the replacement instance has access to the required dataset. Which of the following options is the MOST cost-optimal and resource-efficient solution to build this fleet of EC2 instances?
A streaming solutions company is building a video streaming product by using an Application Load Balancer (ALB) that routes the requests to the underlying EC2 instances. The engineering team has noticed a peculiar pattern. The ALB removes an instance whenever it is detected as unhealthy but the Auto Scaling group fails to kick-in and provision the replacement instance. What could explain this anomaly?
A chip design startup is running an Electronic Design Automation (EDA) application, which is a high-performance workflow used to simulate performance and failures during the design phase of silicon chip production. The application produces massive volumes of data that can be divided into two categories. The 'hot data' needs to be both processed and stored quickly in a parallel and distributed fashion. The 'cold data' needs to be kept for reference with quick access for reads and updates at a low cost. Which of the following AWS services is BEST suited to accelerate the aforementioned chip design process?
The CTO of an online home rental marketplace wants to re-engineer the caching layer of the current architecture for its relational database. He wants the caching layer to have replication and archival support built into the architecture. Which of the following AWS service offers the capabilities required for the re-engineering of the caching layer?
A software engineering intern at an e-commerce company is documenting the process flow to provision EC2 instances via the Amazon EC2 API.
