A retail company purchases enough on-premises servers each year to handle its projected Black Friday traffic, based on capacity estimates made months in advance. In years when actual demand is lower than projected, the expensive hardware sits idle and depreciates. Which AWS Cloud advantage BEST addresses this problem?
The company's core problem is having to forecast future demand and provision hardware accordingly. AWS lets you scale resources up or down based on actual real-time demand, eliminating the need to guess capacity requirements in advance.
A company runs its application on Amazon EC2 instances within its own VPC. Under the AWS Shared Responsibility Model, who is responsible for patching the guest operating system on these EC2 instances?
For EC2, AWS manages security 'of' the cloud (physical hosts, hypervisor), but the customer is responsible for security 'in' the cloud, which includes guest OS patching, application software, and firewall/security group configuration.
A financial services company needs a dedicated, private network connection between its on-premises data center and AWS to support large, consistent data transfers with predictable, low-latency performance. The connection must not traverse the public internet. Which solution BEST meets these requirements?
AWS Direct Connect establishes a dedicated, private physical network connection between on-premises infrastructure and AWS, bypassing the public internet and providing consistent, low-latency, high-bandwidth throughput ideal for large data transfers.
A retail company runs a business-critical e-commerce workload on AWS and requires a guaranteed response time of less than 15 minutes when that workload is completely down. Which AWS Support plan is the minimum required to meet this requirement?
Only the Enterprise Support plan guarantees a less-than-15-minute response time, and only for business-critical system down cases. It also includes a Technical Account Manager (TAM) for proactive guidance.
A company runs its entire customer-facing application on a single EC2 instance in one Availability Zone. When that instance experienced a hardware fault, the application became completely unavailable for several hours. Which design principle should the company apply to increase resilience against this type of failure?
Designing for failure means assuming any individual component can fail and architecting redundancy, such as running instances across multiple Availability Zones, so a single failure does not cause an outage.
A company stores customer data in Amazon S3 and wants to automatically discover and classify sensitive information such as personally identifiable information (PII) stored in those buckets. Which AWS service should they use?
Amazon Macie uses machine learning and pattern matching to automatically discover, classify, and protect sensitive data such as PII stored in Amazon S3.
A company wants to run several containerized microservices continuously without provisioning, patching, or managing any underlying EC2 instances. Which AWS service BEST meets this requirement?
AWS Fargate is a serverless compute engine for containers used with Amazon ECS or EKS that automatically provisions and scales the underlying infrastructure, removing the need to manage EC2 instances.
A company wants a single AWS tool that automatically inspects their AWS environment and provides real-time recommendations across five categories: cost optimization, performance, security, fault tolerance, and service limits. Which AWS service provides this?
AWS Trusted Advisor inspects an AWS account and provides recommendations across exactly these five categories: cost optimization, performance, security, fault tolerance, and service limits.
Which pillar of the AWS Well-Architected Framework focuses primarily on the ability to run and monitor systems to deliver business value, and to continuously improve supporting processes and procedures?
The Operational Excellence pillar covers running and monitoring systems to deliver business value and continually improving processes and procedures, including automation and learning from operational events.
A company deploys its backend logic entirely using AWS Lambda functions with no EC2 instances involved. Under the AWS Shared Responsibility Model, who is responsible for patching the underlying operating system and runtime environment that executes the Lambda function code?
With serverless services like Lambda, AWS's responsibility expands to include the operating system, runtime patching, and underlying infrastructure, while the customer remains responsible only for their function code, IAM permissions, and configuration.
A company must retain compliance log data for 7 years. The data is accessed frequently during the first 30 days, then rarely afterward, and a retrieval time of several hours is acceptable for archived data. Which S3 storage class should be applied via a lifecycle policy for the long-term archival phase to minimize cost?
S3 Glacier Deep Archive offers the lowest per-GB storage cost in S3, making it ideal for long-term compliance data that is rarely accessed and where retrieval times of hours are acceptable.
A company purchasing a 1-year Standard Reserved Instance wants to maximize their discount compared to On-Demand pricing and is willing to pay the entire cost of the reservation immediately. Which payment option should they choose?
The All Upfront payment option requires paying the full cost of the Reserved Instance term at the start and provides the largest discount of the three available payment options.
