Google Professional Cloud Network Engineer exam dumps: questions 101 to 200 of 789

Correct answers: A, D

• A. Correct.

  Correct: A static route with the next hop set to the NVA's internal IP ensures that traffic from your application VMs is directed to the NVA for inspection.

• B. Incorrect.

  Incorrect: Firewall rules control access but do not define how traffic is routed. This step is not sufficient for routing traffic through the NVA.

• C. Incorrect.

  Incorrect: Policy-based routing is not currently supported in Google Cloud. Static routes must be used instead.

• D. Correct.

  Correct: Enabling IP forwarding on the NVA's VM instance ensures that the appliance can process and forward packets as expected.

• E. Incorrect.

  Incorrect: Route advertisements are used for dynamic routing scenarios with hybrid or multi-cloud setups, not for directing traffic to an NVA within the same VPC.

Correct answers: A, C

• A. Correct.

  Correct: To redirect traffic from Subnet A to Subnet B via the NVA, you need a static route with the destination range of Subnet B and the next hop set to the NVA.

• B. Incorrect.

  Incorrect: While enabling VPC Flow Logs is useful for monitoring, it does not influence how traffic is routed or enable the use of the NVA.

• C. Correct.

  Correct: To ensure return traffic from Subnet B to Subnet A also passes through the NVA, you must define a static route with the destination range of Subnet A and the next hop set to the NVA.

• D. Incorrect.

  Incorrect: Firewall rules control the permissions for traffic but do not determine how traffic is routed through the NVA.

• E. Incorrect.

  Incorrect: Subnet route priority is not a configurable parameter in Google Cloud. Static and custom routes automatically override default routes.

Correct answers: A, B, D

• A. Correct.

  This is correct because a custom static route is needed to direct traffic from the on-premises network to the NVA, specifying the NVA's internal IP address as the next hop ensures that traffic is appropriately routed.

• B. Correct.

  This is correct because policy-based routing allows you to redirect traffic from specific sources (e.g., Google Cloud workloads) to the NVA for inspection based on source IP ranges.

• C. Incorrect.

  This is incorrect because the NVA is not intended to directly communicate with the internet gateway in this scenario. The NVA is used to inspect traffic between on-premises and Google Cloud workloads, not handle internet-bound traffic.

• D. Correct.

  This is correct because a custom static route ensures that traffic inspected by the NVA can be forwarded back to the on-premises network via the Cloud VPN gateway.

• E. Incorrect.

  This is incorrect because configuring a default route with the NVA as the next hop would unintentionally redirect all outbound traffic in the VPC to the NVA, which is not aligned with the scenario's requirements.

Correct answers: A, E

• A. Correct.

  Correct: This ensures all internet-bound traffic is directed to the NVA for inspection before it is routed to its destination.

• B. Incorrect.

  Incorrect: Policy-based routing is not required in this case; static routing is sufficient to redirect all traffic to the NVA.

• C. Incorrect.

  Incorrect: Internal VPC traffic does not need to bypass the NVA in this scenario as the focus is on egress traffic inspection.

• D. Incorrect.

  Incorrect: This bypasses the NVA entirely, defeating the purpose of inspection for outgoing traffic.

• E. Correct.

  Correct: Once the traffic is inspected by the NVA, it must have a route to the internet; otherwise, it will be dropped.

Correct answers: B, D, E

• A. Incorrect.

  This is incorrect because using the default internet gateway as the next hop will bypass the NVA entirely, and traffic will not be inspected as intended.

• B. Correct.

  This is correct because you need to define a custom static route that directs traffic to the NVA instance's internal IP to ensure inspection.

• C. Incorrect.

  This is incorrect because route priority does not determine traffic redirection in this scenario. Instead, custom routes must explicitly define the next hop.

• D. Correct.

  This is correct because the NVA must reside in the same VPC and region to ensure proper routing and communication with the subnet it is inspecting.

• E. Correct.

  This is correct because enabling IP Forwarding on the NVA instance is required to allow traffic to pass through and be inspected before being forwarded to its destination.
