• Question 191:

  The following is a description of the Mesh route establishment in the pro-active mode?

  A. The MP periodically sends a broadcast PREQ, receives the MP/MPP response unicast PREP, and establishes a round-trip route between any two points.
  B. The MPP periodically sends the broadcast RANN, and the received MP sends a unicast PREQ to the MPP. After receiving the MPP, the MPP responds to the PREP and establishes a route between the MP and the MPP.
  C. The MPP periodically sends the broadcast RANN, and the received MP sends a unicast PREP to the MPP to establish a route between the MP and the MPP.
  D. MPP periodically sends a broadcast PREQ, and the received MP responds to the unicast PREP to establish a route between the MP and the MPP.
  C. The MPP periodically sends the broadcast RANN, and the received MP sends a unicast PREP to the MPP to establish a route between the MP and the MPP.

• Question 192:

  A company needs to build a large VLAN three-tier network in its office building. There are a large number of employees in the office building, and employees will pick up the WLAN network at the entrance of the office building and roam to their respective work areas. The company has deployed a wired network and has a mature wired network management mechanism. It is hoped that the newly deployed WLAN network can be managed and maintained with the original wired network. The planned IP address of the AC is 172.168.11.1. The network engineer is planning the WLAN. When networking, what is the correct way to do this?

  A. To facilitate the unified management of wired and wireless networks, you can adopt the networking structure of the frame switch + ACU2 to configure wired and wireless integration.
  B. Due to the large number of employees and access to the WLAN network at the entrance of the office building, you can configure VLAN Pool to solve the problem of a large number of IP address requests in a specific area.
  C. On a large WLAM network, the AC manages many APs. To facilitate unified management and maintenance, all APs connected to the AC are added to the same AP group for maintenance.
  D. In the Layer 3 WLAN network, you need to configure the Option 43 field on the Windows 2003 DHCP server as 030B3137322E3136382E31312E31.

  C. Source addresses of Disassociation and Deauthentication frames
  D. Destination addresses of Disassociation and Deauthentication frames
  C. Source addresses of Disassociation and Deauthentication frames

• Question 194:

  D. [AC-wlan-view] sta-load-balance static-group name static-1
  D. [AC-wlan-view] sta-load-balance static-group name static-1

• Question 195:

  A large enterprise uses direct forwarding for some SSIDs when deploying the WLAN. Which of the following are the characteristics of direct forwarding? (Multiple Choice)

  A. Service data do not need to be forwarded to the AC. There is no forwarding bottleneck.
  B. Wireless traffic can be centrally controlled. This forwarding mode has obvious advantages in user policy control and wireless roaming.
  C. Data packets are forwarded in a more secure way.
  D. It is easy for AC capacity expansion. You only need to increase the number of independent ACs.
  A. Service data do not need to be forwarded to the AC. There is no forwarding bottleneck.
  D. It is easy for AC capacity expansion. You only need to increase the number of independent ACs.

• Question 196:

  Which of the following statements about Option 43 in the N+l backup networking are TRUE? (Multiple Choice)

  A. After Option 43 is configured, the AP only unicasts Discovery Request messages to the AC's IP addresses carried in Option 43.
  B. If the AC with the IP address carried in Option 43 does not respond, the AP fails to discover the AC.
  C. When configuring Option 43, you need to specify IP addresses of the active and standby ACs for the AP, and IP addresses of the other active ACs.
  D. The command for setting Option 43 on the DHCP server to IP addresses of the active and standby ACs is option 43 sub-option 2 ip-address ip-address and.
  A. After Option 43 is configured, the AP only unicasts Discovery Request messages to the AC's IP addresses carried in Option 43.
