Huawei HCIE-Security (Huawei Certified Internetwork Expert-Security) (H12-731中文版) Sample Questions:

1. 某局点微信语音（ TCP )业务出现延时较大的故障,延时达到 3 秒。防火墙作为其出口 NAT 网关,配置了 easy-ip 的 nat 方式（单出口),关闭了链路状态检测, TCP 老化时间为 30 秒,业务流量较小,到语音服务器的会话数接近 5 万。通过会话可以看到大量的单向访问语音服务器的报文。
造成这一故障的原因及解决方案正确的是 ?

A) 解决方案可以 TCP 老化时间增加到 600 秒。
B) TCF 会话老化时间太短,防火墙新建会话比较耗时。
C) 防火墙会话老化后,新的连接做 NAT 后的端口与原来和服务器建立连接的端口不一致,导致服务器没有响应,需要客户端超时后再重新建立连接才能发送数据。
D) 如果链路不存在来回路径不一致,可以开启链路状态检测功能,老化时间默认,可以解决这一问题。

2. 内部网络安全,关于规划部署建议优先考虑项有以下哪些选项 ?

A) 开启 DDoS 功能
B) 防火墙和交换机虚拟化实现业务隔离
C) 应用三层架构平面隔离
D) 计算网络和存储网络物理隔离
