H3C GB0-342 Exam Syllabus Topics:

H3CSE-WLAN Sample Questions:

1. it ap 不能注册到控制器,可以用以下哪些命令查看（多选)

A) debugging wlan Iwapp event
B) debugging wlan Iwapp error
C) debugging wlan Iwapp packet control receive
D) debugging wlan Iwapp packet control send

2. 以下对室分系统描述正确的是
以下对室内分布系统合路原则描述正确的是 ______

A) AP 合路点必须在有源设备（主要是干放)后一级,因为有源设备不能通过 wlan 信号,无馈系统的所有无线器件（包括功分器,线缆,跳线等)必须能支持 WLAN 频段（ 2.4GHZ~2.4835Ghz ),且衰减控制点在一定范围内。
B) 一般不建议在 AP 的后面增加 WLAN 功放
C) 受用户数的限制,单个 AP 所接天线数建议不超过 15 个
D) AP 安装位置应保证以太网可达（与接入交换机之间小于 100 米),在无 POE 交换机的情况下应保证能提供本地供电。
E) 根据实测经验,在室内分布式系统中天线口的 wlan 信号功率在 10dBm 左右比较理想,最小不低于 5dBm ,一般要求 wlan AP 合路点的发射功率至少不低于 3G/GSM/CDMA 信号功率

3. 在点到点（ PtP )的无线传输中,最适合的天线类型是

A) 一端全向天线,一端定向天线
B) 两端定向天线
C) 两端全向天线

4. FIT AP 网络部署和实施的便捷指出在于 AP 可以即插即用,在进行 AP 的安装前,建议进行以下哪些操作 ?

A) 记录 AP 安装点和序列号, MAC 地址对应关系
B) 记录 AP 和所选交换机以其端口的对应关系
C) 现场 AP 进行注册操作,保证所有到货 AP 都可以成功在 AC 上注册
D) 进行 License 的相关操作,确保 AC 的 License 规格可以满足要求

5. 在使用 WLAN 双频合路器进行室内分布式系统合路扩容时,以下说法正确的是:

A) 项目实施中,如果使用 FIT AP 进行 WLAN 双频合路,建议开启无线控制器 +FIT AP 的负载分担功能,可以使无线用户均匀的连接到两个 AP 上,避免一个 AP 上用户很多,而另一个 AP 上的用户很少的情况发生。
B) 采用此合路扩容方案时, WLAN 合路器引入的插损约为 2dB ,在计算信号强度时需要考虑在内。
C) WLAN 合路扩容方案可以通过两个 AP 采用不同的信道合路来提高整个 WLAN 系统容量。
D) 目前此扩容方案由于受器件特性限制,只支持 channel 1 和 channel 11 合路扩容,但是合路器的两个端口哪个接 channel 1 的 AP ,哪个接 channel 11 的 AP 并没有严格的限制。
