ワイヤレスCiscoSD-Access展開では、ユーザが単一のWLCを使用して別のアクセススイッチ上のあるアクセスポイントから別のアクセスポイントに移動するときに使用されるローミング方法はどれですか。
正解:B
SDA RoamingSDA supports two additional types of roaming, which are Intra-xTR and Inter-xTR.
In SDA, xTR stands for an access-switch that is a fabric edge node. It serves both as an ingress tunnel router as well as an egress tunnel router.
Intra-xTR
When a client on a fabric enabled WLAN, roams from an access point to another access point on the same access-switch, it is called Intra-xTR. Here, the local client database and client history table are updated with the information of the newly associated access point.
Inter-xTR.
When a client on a fabric enabled WLAN, roams from an access point to another access point on a different access-switch, it is called Inter-xTR.
