课程名称:Symantec Cluster Server 6.1 管理 250-254 考试 课程概述: 本课程侧重于 Symantec Cluster Server (SCS) 6.1 的管理实践,旨在帮助学员通过 250-254 认证考试。课程内容涵盖了 SCS 的核心功能、配置和故障排除。 通过课程提供的示例问题,我们可以了解课程的关键知识点: * **应用程序前置条件:** 在将应用程序纳入 SCS 控制之前,必须满足特定条件,例如应用程序是否对所有节点可用,以及其关机过程是否能够执行优雅的清理操作。 * **Symantec Operation Readiness Tools (SORT):** SORT 工具在 SCS 环境中扮演重要角色,例如维护用于灾难恢复的通用配置文件。 * **LLT 状态查看:** `lltstat -nvv` 命令在双节点集群中用于显示集群中所有节点的 LLT 信息。 * **集群网络配置:** 当两个 Veritas 集群共享同一个私有心跳网络交换机时,需要确保集群 ID 在所有节点上唯一。 * **磁盘 I/O 故障隔离配置:** 配置基于磁盘的 I/O 故障隔离需要特定条件,例如存储阵列必须支持 SCSI3-PR,并且 LUN 必须在 `vx disk` 列表中有可见性。 总而言之,本课程为 Symantec Cluster Server 6.1 的系统管理员提供了扎实的理论知识和实践指导,帮助他们掌握集群的管理和维护技能。
Sample Questions:An administrator is verifying the prerequisites of an application to ensure it can be placed under Symantec Cluster Server control. Which two prerequisites must be met to accomplish this goal? (Select two.)The operating system automatically starts the application.The application is available to all nodes.The shutdown process should be graceful performing cleanup operations.The hardware administrative IP addresses are configured by Cluster Server on all nodes.The shared storage is managed by Symantec Volume Manager.Symantec Operation Readiness Tools (SORT) provides which service?It automates installation of product updates.It manages notifications for changes in patches.It stores operating system patches required for upgrade.It maintains common config files required for Disaster Recovery.When run in a two node cluster, what does the lltstat -nvv command show?only LLT information for the node the command was run onLLT information for all configured nodes in the clusterLLT information for any cluster nodes attached to the same switchonly LLT information for nodes verified by Veritas Cluster Server to be activeWhat is required in order to have two separate Veritas clusters share a common private heartbeat network switch?GAB network IDs must be unique across the clusters.All node IDs must be unique across the clusters.Cluster IDs must be unique across the clusters.All LLT node IDs must be unique across the clusters.What are two requirements for configuring disk-based I/O fencing on supported storage arrays?
