hard📝 Application Q8 of 15

AWS - VPC Fundamentals

ACreate two separate VPCs and establish a VPC peering connection with appropriate route tables

BDeploy both applications in the same subnet within a single VPC

CUse a single VPC with public subnets and security groups to isolate traffic

DPlace both applications in different Availability Zones within the same VPC

Step-by-Step Solution

Solution:

Step 1: Understand isolation needs
Separate VPCs provide strong network isolation by default.
Step 2: Enable controlled communication
VPC peering allows secure, private communication between VPCs.
Step 3: Evaluate other options
Same subnet or VPC with security groups offers less isolation; different AZs do not isolate networks.
Final Answer:
Create two separate VPCs and establish a VPC peering connection with appropriate route tables -> Option A
Quick Check:
Separate VPCs + peering = isolation + communication [OK]

Quick Trick: Use separate VPCs with peering for isolation and communication [OK]

Common Mistakes:

Assuming security groups alone isolate applications
Thinking different AZs isolate networks
Using public subnets for isolation
