  B. IM
  C. Web
  D. Email
  E. VoIP
  B. IM

• Question 56:

  What is the correct statement about VLAN planning for WLAN?

  A. The management VLAN is responsible for transmitting packets forwarded through the CAPWAP tunnel, so the management VLAN must be VLAN 1.
  B. When using tunnel forwarding, the management VLAN and service VLAN cannot be the same VLAN.

• Question 58:

  In a WDS scenario, how many Leaf APs can a Fire AP associate with without considering bandwidth?

  A. 3
  B. 6
  C. 15

  B. 6

• Question 59:

  What is wrong about the dual link backup description below?

  A. The process of establishing the primary CAPWAP tunnel after the dual-link backup function is configured is the same as that of the normal CAPWAP tunnel.
  B. If the dual-link active/standby configuration is configured with the dual-link active/standby configuration, the AP will preferentially select the dual-link active/standby configuration.
  C. Dual-link cold standby is compared to hot standby. After detecting the failure of the primary CAPWAP tunnel, the backup CAPWAP tunnel is established to implement services. Break forwarding
  D. Dual-link hot backup is relative to cold standby. The CAPWAP tunnel fault detection is performed between the active and standby ACs, and the HSB channel synchronizes the status information in real time.
