Advanced Networking Concepts Flashcards
| Front | Back |
| AWS Transit Gateway | Central hub to connect VPCs, on-premises networks, and remote locations through a single gateway |
| Classic Load Balancer vs Application Load Balancer | ELB supports layer 4 while ALB supports layer 7 for advanced routing features |
| Cross-region VPC peering | Allows secure communication between VPCs in different AWS regions |
| Direct Connect benefits | Provides dedicated bandwidth and reduced latency for hybrid networking |
| DNS resolution in VPCs | Enables hostname-to-IP mapping using Amazon-provided or custom DNS servers |
| Elastic IP benefits | Static IP address that remains unchanged even when instances are stopped or replaced |
| Hybrid connectivity | Provides seamless communication between on-premises and cloud resources |
| NAT gateway purpose | Allows outgoing internet traffic from instances in a private subnet |
| Private Link | Allows private access to AWS services and VPC endpoints without exposing traffic to the public internet |
| Route 53 failover routing | Redirects traffic to backup resources in case the primary resource becomes unavailable |
| Route 53 geolocation routing | Routes traffic based on the user's geographic location |
| Route propagation in Transit Gateway | Automatically shares routes based on dynamically connected VPNs and Direct Connects |
| Routing policies | Rules defining how network traffic is directed between various endpoints |
| Security group vs Network ACL | Security groups operate at the instance level, whereas NACLs operate at the subnet level |
| Traffic mirroring use case | Used for packet inspection, troubleshooting, and intrusion detection analysis |
| Transit Gateway route table | Controls routing between attached VPCs, VPNs, and AWS Direct Connect |
| VPC endpoint types | Includes Gateway endpoints (S3 and DynamoDB) and Interface endpoints for other services |
| VPC peering | Allows direct network traffic between two VPCs without requiring a gateway or VPN connection |
| VPC peering limitations | Peered VPCs cannot have overlapping CIDR blocks |
