In an AWS architecture blueprint, a box with the label 'VPC Peering' connecting two VPC boundaries represents what connectivity type?
Answer: A direct private network connection between two VPCs enabling resource communication
VPC Peering creates a direct private connection between two VPCs, allowing resources to communicate as if on the same network.
When an AWS diagram shows a Transit Gateway icon at the center with multiple VPCs and on-premises connections radiating outward, this represents what topology?
Answer: A hub-and-spoke network topology centralizing connectivity through Transit Gateway
Transit Gateway acts as a hub, creating a hub-and-spoke topology where all VPCs and on-premises networks connect through a central gateway.
In AWS architecture diagrams, a yellow lightning bolt or queue icon between two services most commonly represents which AWS service?
Answer: Amazon SQS for decoupled message queuing
SQS is depicted with a queue icon representing its FIFO or standard message queue that decouples producers from consumers.
What does a stack of identical server icons in an AWS architecture diagram most likely represent?
Answer: A horizontally scaled fleet of instances or replicated service tier
Stacked server icons represent horizontal scaling—multiple identical instances of the same service running in parallel to handle load.
In an AWS reference architecture diagram, a dotted boundary surrounding resources labeled 'Region: us-east-1' indicates what architectural scope?
Answer: All resources within the diagram are deployed to that specific AWS geographic region
A region boundary box encloses all resources deployed within that AWS geographic region, such as us-east-1 (N. Virginia).
When an AWS architecture diagram shows an arrow from EC2 to DynamoDB labeled 'IAM Role', what does this arrow represent?
Answer: Permissions granted to the EC2 instance to access DynamoDB via an attached IAM role
An IAM Role arrow indicates that the EC2 instance has an attached IAM role granting it specific permissions to call the DynamoDB API.
In an AWS architecture diagram, what does a diagonal arrow labeled 'Failover' between two RDS instances in different AZs represent?
Answer: Automatic database failover to a standby instance in another AZ during a primary failure
RDS Multi-AZ automatically fails over to a synchronous standby replica in another AZ when the primary instance experiences an outage.
