Question
A small company hosting multiple virtualized client servers on a single host is considering adding a new host to create a cluster. The new host hardware and operating system will be different from the first host, but the underlying virtualization technology will be compatible. Both hosts will be connected to a shared iSCSI storage solution. Which of the following is the hosting company MOST likely trying to achieve?
Options
- AIncreased customer data availability
- BIncreased customer data confidentiality
- CIncreased security through provisioning
- DIncreased security through data integrity

Explanation
When two hypervisor hosts share a common storage backend (iSCSI SAN) and form a cluster, the primary benefit is high availability. If one host fails, the virtual machines running on it can be restarted or migrated to the surviving host with minimal downtime, keeping customer data and services accessible. This is a classic HA (High Availability) architecture pattern. Confidentiality (B) is not improved by clustering - it depends on encryption and access controls, not redundancy. 'Security through provisioning' (C) is not a standard concept that applies here. Data integrity (D) relates to preventing unauthorized modification, which clustering does not directly address. The scenario's combination of clustered hosts plus shared storage is a textbook availability solution.
