Q: A Domain Name System (DNS) port problem is causing a video conferencing application to malfunction. Which record has to be changed in order to resolve the problem?
- Canonical name (CNAME)
- Host (A)
- Text (TXT)
- Service record (SRV)
Explanation: It is recommended that you review the SRV (Service) records if a video conferencing program is experiencing problems that are associated with DNS ports. An SRV record contains information about the services that are offered, such as the port number and the protocol that is being used. To fix the DNS port problem, you need to make sure that the SRV records that are linked with the video conferencing application are appropriately set.
