最新的 HCNP-WLAN H12-321-ENU 免費考試真題：

1. 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

2. What radio calibration measures can be taken to ensure that the APs work at the optimal performance? (Multiple Choice)

A) AP power adjustment
B) AP SNR adjustment
C) Dynamic EDCA parameter adjustment
D) AP channel adjustment

3. Which are the methods to prevent loops on a multi-MPP Mesh network? (Multiple Choice)

A) TTL
B) Repeated frame sequence number check
C) MSTP

4. In smart roaming, an AP specifies the target AP for 802.11v-capable STAs. In this way, STAs actively roam to the target AP, and the original AP does not need to kick the STAs offline.

A) TRUE
B) FALSE

5. Which statements about reliability measurement are TRUE? (Multiple Choice)

A) MTBF refers to the average time (usually expressed in hours) from the fault occurrence time to the fault recovery time. A larger MTBF indicates a higher reliability.
B) Generally, system reliability is determined by mean time between failure (MTBF) and mean time to repair (MTTR).
C) The formula for calculating the MTTR is as follows: MTTR= Fault detection time + Hardware replacement time + System initialization time + Link recovery time + Route convergence time + Forwarding recovery time A smaller MTTR indicates a higher reliability.
D) MTTR refers to the average time from the fault occurrence time to the fault recovery time.
