Questions # 34:

In a dual-link backup scenario, the active/standby link switchover mode is set to priority. When the active link recovers, the AP detects that the original active link has a higher priority and triggers a switchback. How many Echo intervals does the AP wait for before switching back to the original primary WAC?

Options:

Answer

Explanation

In a dual-link backup scenario, when the active link recovers, the AP waits for 15 Echo intervals before switching back to the original primary WAC. This prevents frequent link switchovers caused by unstable links.

Questions # 35:

In a dual-link HSB scenario, after an AP sets up CAPWAP links with the active and standby WACs, which of the following types of packets does the AP periodically send to the WACs to detect link status?

Options:

DTLS

Join

Echo

Keepalive

Answer

Explanation

In a dual-link HSB scenario, after an AP sets up CAPWAP links with the active and standby WACs, the AP periodically sends Echo packets to the WACs to detect link status. The Echo packets are sent every 30 seconds by default.

Questions # 36:

Which of the following advantages does BSS coloring provide in Wi-Fi 6? (Select All that Apply)

Options:

Higher packet rate on the air interface

Enhanced encryption on the air interface

More efficient channel use

Higher concurrency in high-density scenarios

Answer

A, C, D

Explanation

BSS coloring is a feature introduced in Wi-Fi 6 that assigns different colors to different BSSs to reduce co-channel interference. BSS coloring provides the following advantages:

Higher packet rate on the air interface: BSS coloring reduces collisions between packets from different BSSs on the same channel, improving packet transmission efficiency.

More efficient channel use: BSS coloring allows spatial reuse of channels by different BSSs, increasing channel utilization.

Higher concurrency in high-density scenarios: BSS coloring reduces interference among neighboring APs and improves network performance in high-density scenarios.

Questions # 38:

Which of the following key factors is used by the CloudCampus cloud management platform to determine the tenant to which a device belongs?

Options:

Device ESN

Device IP address

Device MAC address

Device model

Answer

Explanation

The device ESN (Electronic Serial Number) is a unique identifier that is used by the CloudCampus cloud management platform to determine the tenant to which a device belongs. The device ESN is bound to a tenant when a device is added to the platform.
