Huawei HCIP-WLAN CEWA(Huawei Certified ICT Professional-Wireless Local Area Network-Constructing Enterprise WLAN Architecture) - H12-321-ENU Exam Practice Test

A. Smart roaming can be implemented only when it is supported by STAs. B. Smart roaming directs sticky STAs to APs with better signals, preventing STAs from sticking to the original AP. C. Smart roaming directs STAs to APs with better signals in a timely manner. D. Smart roaming enables the active probe function, so that APs can quickly collect neighbor information. Once a neighboring AP meets the condition, active roaming is triggered.

A. AD server B. DNS server C. RADIUS server D. LDAP server

A. 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. B. 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. C. Configure the transmit power on the 5 GH radio 3 dB to 8 dB higher than that on the 2.4 GHz radio. D. 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.

A. MAP B. MPP C. VAP D. MP

A. An AP periodically exchanges CAPWAP packets only with the active AC to detect link status. B. An AP periodically exchanges CAPWAP packets with both the active and standby ACs to detect link status. C. An AP sets up CAPWAP tunnels with both the active and standby ACs. D. An AP sets up a CAPWAP tunnel only with the active AC.

A. Destination port number in the packets that the WLAN device sends to the Portal server B. Number of the port that WLAN device uses to process Portal protocol packets C. Number of the port that the WLAN device uses to receive Portal protocol packets D. [AC] web-auth-server listening-port 2000 E. Source port number in the packets that the WLAN device sends to the Portal server

A. Network printer B. Mobile terminal, such as a smartphone C. Testing PC running a Linux system D. Office PC running a Windows OS

A. The first synchronization must be manual, and automatic synchronization can be used subsequently. B. The Agile Controller can only use one synchronization mode, which prevents interference between the two modes. C. The automatic synchronization time can be modified. D. Manual synchronization can be used only three times within a single day, which prevents increase of network loads.

A. 802.1x is a technological system, in which RADIUS is included. B. 802.1x and RADIUS are different technologies, but they are often used together for user access control. C. 802.1x and RADIUS are different names of the same technology. D. 802.1x and RADIUS are different and are not used together.

A. FALSE B. TRUE
