2V0-41.24 Question 183
Select 4A company is implementing NSX-T Data Center in their environment and needs to configure a DNS forwarder service to ensure proper name resolution for their workloads. They want to use the DNS forwarder provided by NSX-T to forward queries to their upstream DNS server located in the corporate network. What steps must they take to properly configure this service?
- A
Deploy an NSX Edge node and ensure it is part of the Tier-0 or Tier-1 gateway.
- B
Configure DNS zones and associate them with the DNS forwarder service.
- C
Set up a NAT rule to redirect DNS traffic from Tier-1 to Tier-0 gateway.
- D
Specify the IP address of the upstream DNS server in the DNS forwarder configuration.
- E
Enable the DNS forwarder service on the Tier-1 gateway.
- F
Manually create static DNS entries for all workloads using the DNS forwarder.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
To use the DNS forwarder service in NSX-T, an NSX Edge node must be part of the Tier-0 or Tier-1 gateway. The DNS forwarder requires DNS zones to define the scope of its operation, and the upstream DNS server's IP address must be configured so it can forward unresolved queries. Additionally, the DNS forwarder service must be explicitly enabled on the Tier-1 gateway. Static DNS entries are not required as the service dynamically forwards unresolved queries.
- A. Correct.
Correct: The DNS forwarder service in NSX-T requires an NSX Edge node to be deployed and connected to a Tier-0 or Tier-1 gateway as it processes DNS traffic.
- B. Correct.
Correct: Configuring DNS zones and associating them with the DNS forwarder service is necessary to define the scope of DNS queries it will handle.
- C. Incorrect.
Incorrect: A NAT rule is not required to redirect DNS traffic between Tier-1 and Tier-0 gateways for the DNS forwarder to work.
- D. Correct.
Correct: The upstream DNS server's IP address must be specified so the DNS forwarder knows where to forward unresolved queries.
- E. Correct.
Correct: The DNS forwarder service must be enabled on the Tier-1 gateway to start processing DNS queries.
- F. Incorrect.
Incorrect: Manually creating static DNS entries is not required for the DNS forwarder service; it forwards queries dynamically to the upstream DNS server.
