The performance testing team finds that an API hosted in a remote datacenter is experiencing...

When APIs are remote, latency is introduced by frequent token validation requests. EnablingCache Tokenon the OAuth Resource Server reduces repeated validation calls and improves performance.

Exact Extract:

“The OAuth Resource Server configuration includes aCache Tokenoption that improves performance by reducing round trips for token validation.”

Option Ais incorrect — key rolling affects cryptographic keys, not API latency.

Option Bis incorrect — virtual hosts control external FQDNs, not performance.

Option Cis incorrect — token attribute size does not significantly affect remote latency.

Option Dis correct — caching tokens reduces validation overhead.
