• Question 241:

  Configure the Option 43 field on the Windows 2003 DHCP server. For example, configure the character string 030C3139322E3136382E32322E31 to indicate the IP address 192.168.22.1. In the character string, 03 is a fixed value; 0C is 12 in decimal format, indicating the string length of the IP address. The IP address 192.168.22.1 has a total of 12 characters. The hexadecimal value 31 is the ASCII value of 1, 39 is the ASCII value of 9, and so on. 2E is the ASCII value of dots. Based on the preceding example, what is the character string corresponding to the IP address 32.15.2.14?

  A. 030733322E31352E322E3134
  B. 030A33322E31352E322E3134
  C. 030A3033322E3031352E3030322E303134
  D. 030A32332E35312E322E3431
  B. 030A33322E31352E322E3134

• Question 242:

  As shown in the figure, in the dual-link load balancing hot standby network, AP1 is a new online AP, and both ACs have access configuration. Which AC does AP1 choose to access?

  A. AC1
  B. AC2
  C. Random access
  D. Will not access
  A. AC1

• Question 243:

  Which statements about roaming are TRUE? (Multiple Choice)

  A. STA roaming indicates the process in which STAs switch from one AP to another.
  B. In both Layer 2 and Layer 3 roaming, STAs' IP addresses remain unchanged.
  C. The APs used to implement WLAN roaming must be of the same model.
  D. When an AC receives an association/re-association request, it determines that the STA roams if an entry about the STA already exists.
  A. STA roaming indicates the process in which STAs switch from one AP to another.
  B. In both Layer 2 and Layer 3 roaming, STAs' IP addresses remain unchanged.
  D. When an AC receives an association/re-association request, it determines that the STA roams if an entry about the STA already exists.

• Question 244:

  The following is true about the three backup methods?

  A. Dual-link hot backup: Back up AP and STA information at the same time, and back up CAPWAP link information.
  B. VRRP hot backup: back up AP and STA information at the same time, and back up CAPWAP link information.
  C. Whether a cold backup or a hot backup is a backup AC only supports backup for one primary AC.
  D. Dual-link backup is a cold backup and does not back up STA information. The AP establishes two links with the active and standby ACs at the same time. During the active/standby switchover or the switchback process, the STA needs to go online again, and the service will be temporarily interrupted.
  D. Dual-link backup is a cold backup and does not back up STA information. The AP establishes two links with the active and standby ACs at the same time. During the active/standby switchover or the switchback process, the STA needs to go online again, and the service will be temporarily interrupted.
