A. B. C. D. E.Explanation.
The OAuth access token issued by Cisco Unified CM's authorization service is used to authenticate and authorize access to the Cisco Unified CM services. The default lifetime of this access token is 120 minutes.
When a Jabber client obtains an access token from the Cisco Unified CM's authorization service, it uses the token to access the service. The Jabber client keeps track of the time when it obtained the access token.
To ensure uninterrupted access to the service, the Jabber client needs to obtain a new access token before the current token expires. If the Jabber client attempts to access the service with an expired access token, the Cisco Unified CM's authorization service will reject the request, and the Jabber client will need to obtain a new access token to access the service again.
Based on the information given, the Jabber client will try to obtain a new access token when its current access token is about to expire. The Jabber client will try to obtain a new access token before the expiration time, to avoid any interruption in service.
Option A: After its current access token is 90 minutes old This option is incorrect because the Jabber client will try to obtain a new access token before the current access token expires, which is at 120 minutes.
Option B: After its current access token is 60 minutes old This option is incorrect because the Jabber client will try to obtain a new access token before the current access token expires, which is at 120 minutes.
Option C: After its current access token is 120 minutes old This option is incorrect because the Jabber client will need to obtain a new access token before the current access token expires, which is at 120 minutes.
Option D: After its current access token is 100 minutes old This option is incorrect because the Jabber client will need to obtain a new access token before the current access token expires, which is at 120 minutes.
Option E: Never This option is incorrect because the Jabber client will need to obtain a new access token before the current access token expires, which is at 120 minutes. The Jabber client will try to obtain a new access token before the current access token expires to avoid any interruption in service.
Therefore, the correct answer is Option C: After its current access token is 120 minutes old.
