**课程名称：** FN0-125 Foundry Networks Certified Engineer (FNCNE) 考试 **课程概述（重点提炼）：** 本课程旨在为考生提供 Foundry Networks Certified Engineer (FNCNE) 认证考试所需的知识和技能。课程内容涵盖了 Foundry 负载均衡设备的配置和管理，重点关注以下技术概念： * **Session Capacity Threshold (会话容量阈值):** 定义了服务器可用会话的百分比、服务器的总会话容量、已使用的总会话数以及配置的会话数。 * **Concurrent Connections (并发连接):** 允许客户端与同一个服务器建立多个连接。 * **Load Balancing Mechanism (负载均衡机制):** 在防火墙负载均衡模式下，数据包通过源和目标 IP 地址派生的哈希值进行负载均衡。 * **Reassign-threshold (重新分配阈值):** 用于标记服务器端口失败。 * **Cookie Hashing (Cookie 哈希):** 确保请求发送到由服务器分配的 Cookie ID 的服务器。 * **Layer 3 Health Check (第三层健康检查):** 指 Foundry 发送的 ping 检测本地或真实服务器。
Sample Questions:Session Capacity Threshold defines:The percent of remaining sessions available on the Server IronThe total session capacity of the Server IronThe total number of sessions used on the Server IronThe total number of sessions that are configured on the real serversConcurrent connections allow a client to always make:A connection to one server and allow the server to make a connection to another serverMultiple connections to the same Server IronMultiple connections to the same serverMultiple connections to the same server's applicationAn HTTP to one server and an FTP connection at the same time to another serverOn a Server Iron XL configured for firewall load balancing, the packet are load balanced using:The hash value derived from the source and destination IP addressesThe session tables traded by the XLsThe firewall pathThe MAC address set in the Server IronThe reassign-threshold is used to:Reassign the port to another serverReassign another server to the VIPMark a server port failedMark a server failedUsing cookie hashing allows the request to go to:The server assigned to the hash bucketThe configured serverThe server available according to the balancing predictorThe server that issued the cookie IDThe server assigned to the cookie ID by the Server IronWhat is a Layer3 Health Check?It's a session table entry for the application running.It's the third step in the Health Check processIt's an ARP request sent by the Server IronIt's a request made to a predefined TCP or UDP portIt's a ping sent by the Server Iron to the local or real servers
