In an AWS architecture diagram, a dashed border surrounding multiple resources typically indicates what?
Answer: An Auto Scaling group boundary
Dashed borders in AWS diagrams conventionally represent Auto Scaling groups, while solid borders represent VPCs and AZs.
Which symbol shape is used in AWS reference architecture diagrams to represent an Internet Gateway?
Answer: A globe icon within a square
AWS represents an Internet Gateway using a globe/world icon, indicating internet connectivity from the VPC.
In an AWS network diagram, what does a line with a padlock icon between two nodes represent?
Answer: An encrypted or secure communication channel

Answer: Using a different color (e.g., lighter shade) or a direct route to an Internet Gateway
Public subnets are typically shown in a lighter color and have a route line connecting to the Internet Gateway, while private subnets do not.
When reading an AWS architecture blueprint, a bidirectional arrow between two services indicates what type of communication?
Answer: Request-response or two-way data exchange
Bidirectional arrows represent two-way communication where both parties send and receive data, such as a client-server request-response pattern.
In an AWS architecture diagram, Route 53 is most commonly depicted as which type of icon?
