Question: 133
Devices must be added to different groups on the Agile Controller to facilitate rule delivery. A . TRUE
B . FALSE
Question: 134
The zone surrounding the line of sight (LOS) is called the Fresnel zone, which is also called the RF LOS. A . TRUE
B . FALSE
Question: 135
In the dual-link cold standby load balancing networking shown in the figure, AP1 has gone online and set up the primary CAPWAP tunnel with AC1.
Which of the following are the possible time points will an active/standby switchover occur under normal circumstances after the primary CAPWAP tunnel between AP1 and AC1 is disconnected? (Multiple Choice)
A . 120 seconds B . 130 seconds C . 145 seconds D . 155 seconds
Which of the following statements about HSB channels in HSB mode is FALSE?
A . It is recommended that an HSB channel between the active and standby ACs be connected through one cable to ensure high reliability.
B . An HSB group is independent from backup services. An HSB group can work properly with no need to bind to an HSB service.
C . In VRRP HSB mode, the HSB channel status changes with the VRRP active/standby status.
D . In dual-link HSB, an HSB channel only functions as a data backup channel and does not have an active/standby status.
Question: 137
On a WLAN that uses the Agile Controller as the admission control server, which of the following is NOT the cause of 802.1x authentication failures?
A . The key used by the Agile Controller to connect to the device is different from the key configured on the device. B . The accounting interval is not configured.
C . Port 1813 is used on the server.
D . The matched authorization rule defines the action "deny".
Question: 138
If three APs are deployed in a small conference room which can accommodate a maximum of 90 people, CAC can be configured on each AP to limit the number of associated STAs within 30 and hide its SSID when the number of associated STAs exceeds 30.
In this way, load balancing can be achieved among APs. A . TRUE
B . FALSE
Question: 139
Which are the methods to prevent loops on a Mesh network? (Multiple Choice) A . STP
B . TTL
C . Repeated frame sequence number check D . MSTP
Which role does the Agile Controller serve in wireless access authentication? A . AD server
B . LDAP server
C . RADIUS server D . DNS server
Question: 141
Which are the omnidirectional antenna patterns? (Multiple Choice)
A . (a)
B . (b)
C . (c)
D . (d)
Question: 142
The AP periodically sends Discovery Request messages to check whether the original primary tunnel recovers. If the original primary tunnel recovers, the AP switches STA data back to this tunnel after a delay because this tunnel has a higher priority than the other one.
To prevent frequent switchovers caused by network flapping, the AP requests ACs to perform revertive switchover
after six Echo intervals, and then sends STA data to the new active AC. A . TRUE
B . FALSE
Question: 143
Which statements are TRUE based on the network of WLAN roaming? (Multiple Choice)
A . For intra-AC roaming, AC1 serves as the HAC for STAs. B . For intra-AC roaming, AC2 serves as the FAC for STAs. C . For inter-AC roaming, AP1 serves as the HAP for STAs. D . For inter-AC roaming, AP3 serves as the FAP for STAs.
