2V0-41.24 Question 185
Select 3An organization has deployed NSX-T in their environment and needs to configure DNS resolution for workloads in their overlay networks. They have decided to use a DNS forwarder service within NSX-T. Which of the following actions are necessary to successfully configure and utilize the DNS forwarder service?
- A
Create a DNS forwarder profile and associate it with an edge cluster.
- B
Configure the DNS forwarder service to forward requests to upstream DNS servers.
- C
Attach the DNS forwarder to a Tier-1 Gateway.
- D
Manually configure DNS settings on each workload in the overlay network.
- E
Enable the DNS forwarder service on a Tier-0 Gateway.
Show answer and explanation
Correct answers: A, B, C
Explanation
The DNS forwarder service in NSX-T simplifies DNS resolution for workloads in overlay networks by forwarding requests to upstream DNS servers. To properly configure the service, you need to create a DNS forwarder profile, associate it with an edge cluster, configure it to forward requests to upstream DNS servers, and attach it to a Tier-1 Gateway. This eliminates the need to manually configure DNS settings on individual workloads and ensures seamless DNS resolution within the NSX-T environment.
- A. Correct.
Correct: Creating a DNS forwarder profile and associating it with an edge cluster is required to enable the DNS forwarder functionality in NSX-T.
- B. Correct.
Correct: The DNS forwarder service must be configured to forward DNS requests to upstream DNS servers to resolve external domain names.
- C. Correct.
Correct: The DNS forwarder must be attached to a Tier-1 Gateway to properly handle DNS requests from workloads connected to it.
- D. Incorrect.
Incorrect: Manually configuring DNS settings on each workload is unnecessary as the DNS forwarder handles DNS resolution automatically for workloads in the overlay network.
- E. Incorrect.
Incorrect: The DNS forwarder service is configured at the Tier-1 Gateway level, not the Tier-0 Gateway level.
