Sample Practice Questions Preview

Question 1: Hybrid Routing with Direct Connect BGP Communities

A multinational enterprise has a critical application hosted in the us-east-1 region. They utilize two AWS Direct Connect (DX) connections terminated at different DX locations for redundancy. The primary DX connection is a 10 Gbps link, and the backup DX connection is a 1 Gbps link. During a routine failure simulation, the network team notices that traffic from AWS to their on-premises data center continues to use the 1 Gbps backup link even when the 10 Gbps primary link is fully operational. The on-premises routers are advertising identical prefixes over both BGP sessions.

Which configuration should the network engineer implement on-premises to ensure AWS prefers the primary 10 Gbps path?

A) Append the on-premises AS-Path multiple times when advertising prefixes over the 1 Gbps backup link BGP session. B) Advertise prefixes over the 10 Gbps primary link with the BGP community 7224:7200 (High Local Preference) and over the 1 Gbps link with 7224:7100 (Low Local Preference). C) Configure a higher Multi-Exit Discriminator (MED) value on the 10 Gbps primary link BGP advertisement compared to the 1 Gbps link. D) Configure the on-premises router to tag the 1 Gbps link advertisements with the BGP community 7224:9100. E) Adjust the Local Preference attribute on the AWS Virtual Private Gateway (VGW) directly via the AWS Management Console to favor the primary connection. F) Utilize BGP weight attributes by configuring a higher weight value on the primary DX connection within the AWS Transit Gateway routing tables.

• Correct Answer: B

• Explanation:

  • Why B is correct: AWS evaluates path selection for outbound traffic (AWS to on-premises) by checking specific attributes in order. Local Preference determined by AWS BGP communities is evaluated first. The community 7224:7300 represents High preference, 7224:7200 is Medium preference, and 7224:7100 is Low preference. By marking the primary link with a higher community preference than the backup link, AWS will strictly prefer the primary path.

  • Why A is incorrect: While AS-Path prepending affects inbound traffic from AWS to on-premises, AWS evaluates BGP communities (Local Preference) before checking the AS-Path length. Because the community value overrides AS-Path evaluation, prepending alone will not fix the issue if a community or path attribute behavior defaults or conflicts.

  • Why C is incorrect: Multi-Exit Discriminator (MED) is evaluated after BGP communities and AS-Path length. Furthermore, a lower MED value is preferred over a higher MED value, so increasing MED on the primary link would make it less preferred, achieving the opposite of the goal.

  • Why D is incorrect: The AWS BGP community 7224:9100 is used for scoping route propagation to the local AWS region only, not for modifying local preference ranking for outbound traffic steering.

  • Why E is incorrect: You cannot manually edit or configure BGP attributes like Local Preference within the VGW or AWS Management Console interface directly. It must be influenced dynamically via standard BGP communities advertised from the customer gateway (CGW).

  • Why F is incorrect: BGP weight is a proprietary attribute that is local to an individual router configuration and cannot be manipulated over the DX BGP peering session directly in this manner to influence global AWS egress routing.

Question 2: Securing Multi-Account VPC Egress Traffic

A financial institution requires all outbound internet traffic originating from application VPCs across 50 AWS accounts to undergo deep packet inspection (DPI) before exiting to the public internet. The solution must scale dynamically up to 40 Gbps, support centralized logging, minimize administrative overhead, and prevent individual application accounts from bypassing the inspection layer.

Which architecture meets these stringent requirements?

A) Deploy a centralized Security VPC containing an AWS Network Firewall cluster spanning multiple Availability Zones. Use an AWS Transit Gateway (TGW) with appliance mode enabled to route all 0.0.0.0/0 traffic from application VPCs through the Security VPC firewall endpoints. B) Deploy a third-party Next-Generation Firewall (NGFW) EC2 instance in each application VPC and configure the local route tables to point 0.0.0.0/0 to the firewall's Elastic Network Interface (ENI). C) Set up a centralized Proxy fleet running on Amazon ECS behind a Network Load Balancer (NLB). Use AWS PrivateLink to connect application VPCs to the NLB, routing all HTTP/HTTPS egress traffic through the endpoint. D) Configure an AWS WAF regional web ACL and associate it directly with the private subnets of each application VPC to filter outbound connections. E) Deploy an internet gateway (IGW) in each application VPC and utilize AWS Firewall Manager to centrally inject a managed rule that intercepts and inspects all raw IP packets at the IGW boundary. F) Establish an AWS Transit Gateway and route traffic directly to an auto-scaling group of Squid Proxy servers placed in a centralized VPC without enabling appliance mode.

• Correct Answer: A

• Explanation:

  • Why A is correct: AWS Transit Gateway combined with centralized AWS Network Firewall inside an inspection VPC is the industry-standard architecture for high-throughput, multi-account egress filtering. Activating "Appliance Mode" on the TGW VPC attachments ensures asymmetric routing is avoided by keeping traffic within the same Availability Zone for the life of the network flow, allowing deep packet inspection to function seamlessly at scale.

  • Why B is incorrect: Deploying individual firewall instances across 50 separate accounts introduces extreme administrative overhead, makes centralized log management exceedingly difficult, complicates auto-scaling, and increases licensing costs drastically.

  • Why C is incorrect: While PrivateLink with proxy servers handles HTTP/HTTPS traffic well, it does not support non-HTTP/HTTPS protocols and cannot perform generic raw Layer 3/4 network layer routing or deep packet inspection for all standard outbound VPC traffic.

  • Why D is incorrect: AWS WAF is designed exclusively to inspect inbound traffic directed toward Application Load Balancers, Amazon API Gateways, or Amazon CloudFront distributions. It cannot filter or inspect outbound egress traffic originating from internal resources.

  • Why E is incorrect: Internet Gateways (IGWs) do not support direct association with AWS WAF or structural deep packet inspection modifications via AWS Firewall Manager. Firewall Manager can orchestrate AWS Network Firewall, but the underlying routing must still use a transit layout like TGW.

  • Why F is incorrect: If Transit Gateway Appliance Mode is not enabled, symmetric routing cannot be guaranteed across multi-AZ firewall/proxy deployments. This causes TCP handshakes to fail because the return traffic could strike a different firewall instance than the originating traffic.

Question 3: Resolving Route 53 Hybrid DNS Resolution Failures

A company is implementing a hybrid cloud architecture. On-premises applications need to resolve private DNS records hosted in an AWS Route 53 Private Hosted Zone (PHZ) named corp.internal. The PHZ is correctly associated with the main hub VPC. An AWS Route 53 Inbound Endpoint has been deployed in the hub VPC with IP addresses 10.100.1.5 and 10.100.2.5. On-premises DNS servers are configured to forward queries for corp.internal to those IPs. However, queries from on-premises clients consistently time out.

Which of the following is the most likely root cause of this connectivity failure?

A) The Route 53 Inbound Endpoint's Security Group does not allow inbound UDP and TCP traffic on port 53 from the on-premises DNS server IP addresses. B) The enableDnsHostnames and enableDnsSupport options are set to false on the on-premises DNS forwarding servers. C) The Route 53 Private Hosted Zone has not been explicitly shared with the on-premises active directory domain controller via an AWS Resource Access Manager (RAM) share. D) The Route 53 Inbound Endpoint requires an attached Internet Gateway to process DNS resolution requests originating outside the AWS network fabric. E) The on-premises routers are failing to encapsulate the DNS queries into an active AWS DataSync transport tunnel before delivering them to the endpoint. F) The Route 53 Outbound Endpoint was not linked to the Inbound Endpoint to allow bidirectional cross-premises routing loop resolution.

• Correct Answer: A

• Explanation:

  • Why A is correct: Route 53 Resolver Endpoints utilize standard Elastic Network Interfaces (ENIs) inside your VPC. These ENIs are governed by Security Groups. DNS queries use both UDP and TCP port 53. If the Security Group assigned to the Inbound Endpoint does not explicitly permit incoming traffic on port 53 from the on-premises network range, the packets are dropped, resulting in a timeout.

  • Why B is incorrect: The settings enableDnsHostnames and enableDnsSupport are configuration attributes specific to an AWS VPC, not configuration parameters found on physical or on-premises enterprise DNS servers.

  • Why C is incorrect: Route 53 Private Hosted Zones cannot be shared with on-premises infrastructure using AWS Resource Access Manager (RAM). They are associated strictly with AWS VPCs. The Inbound Endpoint handles the translation layer for external systems.

  • Why D is incorrect: Route 53 Inbound Endpoints are entirely private infrastructure components. They are designed to be reached over private pathways like AWS Direct Connect or AWS Site-to-Site VPN; they do not need or use an Internet Gateway.

  • Why E is incorrect: AWS DataSync is an automated service used for transferring file and object data into AWS storage systems. It plays no role in encapsulating or routing live network DNS resolution packets.

  • Why F is incorrect: Outbound Endpoints are used exclusively for conditional forwarding from AWS to on-premises DNS servers. They are completely independent of Inbound Endpoints and do not need to be structurally linked to resolve inbound timeouts.
