Online Access Free H12-321-ENU Practice Test

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

Which of the following statements is TRUE about communication between the active/standby ACs with the RADIUS/Portal server in load balancing mode?

• A.The active AC fills the NAS IP address and accounting session ID into accounting and authentication packets.
• B.If the original active AC is not DOWN or the uplink of the original active AC is not disconnected, a loopback interface that uses the same IP address as the active AC needs to be configured on the standby AC. Routes to the loopback interface are not advertised but imported to IGP.
• C.The source IP address carried in RADIUS packets sent by the active and standby ACs must be the same, but the IP addresses of the two ACs configured on the RADIUS server carried in COA/DM packets can be different.
• D.If the original active AC is DOWN or the uplink of the original active AC is disconnected, the active AC needs to process received COA/DM packets and synchronize these packets to the standby AC, and delivers authorization information to APs.

Which of the following methods can implement fast roaming? (Multiple Choice)

• A.PMK caching
• B.Key negotiation between STA and AP
• C.Home agent deployed on the AC
• D.Active STA steering

Which of the following statements about HSB channels in HSB mode is FALSE?

• A.In VRRP HSB mode, the HSB channel status changes with the VRRP active/standby status.
• B.In dual-link HSB, an HSB channel only functions as a data backup channel and does not have an active/standby status.
• C.An HSB group is independent from backup services. An HSB group can work properly with no need to bind to an HSB service.
• D.It is recommended that an HSB channel between the active and standby ACs be connected through one cable to ensure high reliability.

In the dual-link cold backup networking diagram shown in the figure, AP1 goes online, and Aps are allowed to connect to both ACs.

Which AC will AP1 connect to?

• A.AC2
• B.None of them
• C.AC1
• D.Either of them
