# * Q5 : Which of the below 2 is true for idle timeout and session timeout?

(O) Session timeout determines when the client’s authenticated session ends

Idle timeout determines when the client’s authenticated session ends

After the idle timeout passes, when the client tries to connect back, it does a re-association and re-authentication

(O) After the idle timeout passes, when the client tries to connect back, it does a fresh association and authentication

```

1，Session timeout (會話超時)

Session Timer的最高計數1800s，也就是30min。

Session timeout (會話超時)：當該計時器超時時，由於客戶端強制發生重認證，這個時間是從客戶端認證成功後開始計算，進入倒計時。

2，Idle timeout (空閒超時)

閒置計時器的預設值300s，也就是5min。

Idle timeout (空閒超時)：空閒定時器超時時，客戶端會從WLC上被刪除掉（如果一個用戶的設備關機了，或者是筆記本等設備進入睡眠狀態，進入狀態，無法和AP先進行溝通，進行信息 當計時器超時後，下次客戶端協商就需要完成完整的認證過程。

```

# Q9 : Which of the below is true about Mobility?

(X) To Roam between two APs registered to two different WLCs, both WLCs should have same virtual ip, mobility group, AP- Group name

(O) When client roams between WLANs on different subnets, it still retains the IP address

When client roams between WLANs on different subnets, it changes its IP address

# * Q10 : Client Association response (choose two correct statements):

(O) Association response 0 is success and Association response 1 is failure

Association response 1 is success and Association response 0 is failure

Association response 17 indicates client data rate is not allowed and Association response 18 indicates AP is busy and unable to handle client association.

(O) Association response 18 indicates client data rate is not allowed and Association response 17 indicates AP is busy and unable to handle client association.
