Which of the following measures can be taken to make STAs preferentially associate with the 5 GHz radio? (Multiple Choice)

  1. Configure the transmit power on the 5 GH radio 3 dB to 8 dB higher than that on the 2.4 GHz radio.
  2. Configure an AP to preferentially respond to Probe Request packets on the 5 GHz radio sent by STAs, and respond for several times before responding Probe Request packets on the 2.4 GHz radio.
  3. Configure an AP to reject the request from a STA to associate with the 2.4 GHz radio of an AP, and allow STA association only after the number of rejections reaches the threshold. Configure an AP to immediately allow STA association if a STA requests to associate with the 5 GHz radio.
  4. Configure a higher Beacon frame rate, a longer interval for sending Beacon frames, and a smaller number of retransmissions of Probe packets on the 5 GHz radio than on the 2.4 GHz radio.

Answer(s): A,B,C



Which statement about STP on a Mesh network is FALSE?

  1. An AC can issue STP configurations to APs only when wired interfaces of APs are not bound to an Eth-Trunk.
  2. Mesh links only transparently transmit STP packets.
  3. An STP-enabled AP does not forward STP packets to the wireless side. STP takes effect only on the AP's wired side.
  4. STP can prevent loops for multiple rings on a Mesh network.

Answer(s): D



On a WLAN with the WIDS function enabled, APs with the following MAC addresses are detected:

01-01-22-22-33-33
02-01-01-22-33-33
02-01-01-22-33-34
02-01-22-01-01-22

OUI 01-01-22 has been added to the whitelist. Which of these APs will be identified as rogue APs? (Multiple Choice)

  1. 01-01-22-22-33-33
  2. 02-01-01-22-33-33
  3. 02-01-01-22-33-34
  4. 02-01-22-01-01-22

Answer(s): B,C,D



The online process of an AP includes the following phases. What is the correct sequence of these phases?

1. Decide whether to upgrade the AP.
2. The AP and AC establish a CAPWAP tunnel.
3. The AP goes online, and the AC delivers services to the AP.
4. The AP obtains an IP address,

  1. 2->4->l->3
  2. 4->l->2->3
  3. 4->2->l->3
  4. 2->l->4->3

Answer(s): C



Which of the following statements are TRUE about communication between the active/standby ACs with servers in WLAN HSB mode? (Multiple Choice)

  1. In VRRP HSB scenarios, the active and standby ACs can advertise the virtual IP address or MAC address to servers. Only one AC communicates with servers using the virtual IP address.
  2. In load balancing mode, only one AC communicates with servers.
  3. In VRRP HSB scenarios, both the active and standby ACs advertise the virtual IP address or MAC address to servers. The two ACs communicate with servers using the virtual IP address.
  4. In load balancing mode, both the active and standby ACs communicate with servers.

Answer(s): A,D
