In the N+1 backup networking shown in the figure, 300 APs (AP1 to AP300) go online on AC1 and 400 APs (AP301 to AP700) go online on AC2. AC3 is the standby AC and a maximum of 700 online APs can be configured on AC3. However, AC3 allows a maximum of 500 APs to go online concurrently.

Which of the following statements are FALSE when the configuration remains unchanged? (Multiple Choice)

• A.If AC1 fails, 300 APs (AP1 to AP300) perform an active/standby switchover and go online on AC3.
• B.If AC2 fails, 400 APs (AP301 to AP700) perform an active/standby switchover and go online on AC3.
• C.After the faulty AC1 or AC2 recovers, APs that perform a revertive switchover and go online on AC1 or AC2 are uncertain.
• D.If AC1 and AC2 fail concurrently, only 500 APs (AP1 to AP500) perform an active/standby switchover and go online on AC3. The rest 200 APs cannot go online on AC3 and services on these APs are interrupted.

As shown in the figure, there is a 9.1 m high office building at the midpoint of a 3 km point-to-point link.

If the signal transmission frequency is 5.8 GHz, what is the minimum installation height of the receive and transmit antennas based on the following formula?

• A.9.1 m
• B.13 m
• C.10 m
• D.18 m

In the figure, transparent transmission of STP packets may cause mutual impact between loops.

To prevent the impact, which statement about STP is TRUE?

• A.STP needs to be enabled on only MP3's wired interfaces.
• B.STP needs to be enabled on MPI and MP2.
• C.STP needs to be enabled on the wired interfaces of both MPP and MP3.
• D.STP needs to be enabled on only MPP's wired interfaces.

On an intra-frequency Mesh network, two APs provide 200 Mbps bandwidth.
Which is the average bandwidth if one more AP is added to the network?

• A.Up to 100 Mbps
• B.Up to 150 Mbps
• C.Up to 50 Mbps
• D.Up to 200 Mbps

This figure shows the WIDS attack detection process.

After the dynamic blacklist is delivered to an AP, how does the AP process different data traffic during the punish period?

• A.Drop normal data traffic and send attack traffic to the AC
• B.Drop normal data traffic and attack traffic
• C.Forward normal data traffic and send attack traffic to the AC
• D.Forward normal data traffic and drop attack traffic
