Which combination of DTP modes set on adjacent switches will cause the link to become an access link?

For a link to become an access link between two adjacent switches, both switches must be configured with the same DTP (Dynamic Trunking Protocol) mode. This can occur when both switches are set to "access" mode or when one switch is set to "dynamic auto" and the other to "dynamic desirable." In either case, the link will not form a trunk and will operate as an access link, allowing only untagged traffic.
