An engineer is optimizing the wireless network at a customer site. In order to evaluate the quality of the existing wireless network, he uses a terminal plug-in test tool to perform tests.
The test results are shown in the figure below. Which of the following descriptions of the current customer network status are correct? (Multiple choice) 
- A . If customers try the game, they may experience problems such as game lag.
- B . Web page loading time is short and basic services are not a problem
- C . It is recommended to optimize the air interface and reduce the delay of Ping packets.
- D . The current network speed may not meet the needs of high-bandwidth services
Initially, if you use a wireless connection to an AP, which of the following IP addresses can be used by default to log in and manage the FITAP?
- A . 192.168.1.1
- B . 169.254.2.1
- C . 192.168.2.1
- D . 169.254.1.1
In WPA/WPA2 encryption, which of the following keys can be used to encrypt multicast and broadcast wireless messages?
- A . Group Master Key
- B . Pairwise Transient Key
- C . Group Temporal Key
- D . Pairwise Master Key
When using the terminal dialing test tool to conduct network quality assessment tests, in principle, at least 3 points should be selected in the same scenario and each point should be tested at least 3 times in order to ensure the test effect.
- A . True
- B . False
When optimizing wireless networks, it is recommended to configure port isolation on the device interface directly connected to the AP. If port isolation is not configured, a large number of unnecessary broadcast messages may be generated in the VLAN, causing network congestion and affecting user experience.
- A . True
- B . False
By configuring QoS policies based on application protocols, non-critical services can be prevented from excessively occupying wireless resources and causing packet loss for core services.
Which of the following actions can this function perform for the identified application protocol? (Multiple choice)
- A . Limit the rate of specified messages
- B . Modify the priority of the specified message
- C . Discard the specified message
- D . Cache specified messages
When an engineer was debugging a wireless network at a customer site, the radio frequency tuning function configured on the device did not take effect. The engineer checked the current radio frequency tuning status on the wireless controller, and the following was displayed.
After analyzing the displayed information, which of the following may be the cause of the failure of radio frequency calibration? 
- A . No VAP template is configured on the device
- B . The channel and power automatic selection functions are disabled on the device.
- C . AP did not detect neighbor information
- D . Device tuning is not completed
The customer’s existing network has configured inter-WAC roaming. The engineer checked the information of the roaming group on the wireless controller and found the following description of the roaming group. Which one is wrong? 
- A . The terminal can roam normally between the WACs in the above roaming groups.
- B . The current link of WAC with IP address 192.168.10.1 is normal
- C . There are three WACs in this roaming group.
- D . The current link of the WAC with IP address 192.168.10.3 is disconnected
When optimizing wireless network planning, it is also necessary to collect wired network data, including network architecture, key equipment configuration and operating status, etc.
- A . True
- B . False
In the 802.1X authentication system, which of the following situations may cause the terminal to go offline? (Multiple choice)
- A . Access device controls user offline
- B . The authentication server controls the user to go offline
- C . Re-authentication failed and was forced offline
- D . The client goes offline voluntarily
