A financial services company needs a private, dedicated network connection from its on-premises data center to AWS that provides consistent low latency and higher bandwidth than an internet-based connection, and does not traverse the public internet. Which AWS service BEST meets this requirement?
AWS Direct Connect establishes a dedicated private network connection between on-premises infrastructure and AWS, bypassing the public internet and providing consistent, predictable latency and higher throughput.
A DevOps team wants to define their entire AWS infrastructure — VPCs, EC2 instances, security groups, and RDS databases — in version-controlled template files that can be repeatably deployed and updated as a single unit. Which AWS service is designed for this?
AWS CloudFormation lets you define infrastructure as code using JSON or YAML templates, and it manages the creation, update, and deletion of all specified resources as a single stack.
A media company runs a rendering application on multiple EC2 instances that all need simultaneous read/write access to the same shared file system, with automatic scaling of storage capacity as files are added. Which storage service should they use?
Amazon EFS is a fully managed, POSIX-compliant elastic file system that can be mounted concurrently by multiple EC2 instances and automatically scales storage capacity up or down as files are added or removed.
A company hosts a static website on Amazon S3 and wants to reduce latency for users worldwide by caching content at locations physically closer to them, while also reducing direct load on the S3 bucket. Which AWS service should they add in front of S3?
Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations around the world, reducing latency for end users and offloading requests from the origin S3 bucket.
A company needs a relational database that is compatible with MySQL, provides up to 5 times the throughput of standard MySQL on the same hardware, and automatically replicates 6 copies of data across 3 Availability Zones for high durability. Which service should they choose?
Amazon Aurora is AWS's cloud-native relational database engine, compatible with MySQL and PostgreSQL, offering up to 5x the throughput of standard MySQL and a storage layer that automatically replicates 6 copies of data across 3 Availability Zones.
According to AWS global infrastructure design, what is the minimum number of Availability Zones that AWS provisions within each Region?
AWS designs every Region to contain a minimum of 3 Availability Zones, each consisting of one or more discrete data centers with independent power, cooling, and networking, enabling high availability architectures.
