Which OES NetWare product provides high availability of critical network resources?

MySQL is a relational database engine used for data storage, not a high-availability clustering solution for network resources.

Rsync is a file synchronization and transfer utility, not a failover or high-availability clustering service.

iPrint is Novell's network printing management solution and has no role in providing server or resource failover.

eGuide is a web-based LDAP directory lookup tool for finding users and resources, unrelated to high availability.

File Versioning maintains historical snapshots of files for recovery purposes and does not provide server clustering or failover capability.

Novell Cluster Services groups multiple servers into a cluster so that if one node fails, another node immediately takes ownership of its resources and services, eliminating single points of failure. It monitors shared resources continuously and triggers failover without manual intervention, making it the designated high-availability solution within the OES NetWare product set.

Web Application Services hosts web-based applications on OES but does not provide high-availability clustering for network resources.
