CAS-001 Question #122: Real Exam Question with Answer & Explanation
The correct answer is A: Increased customer data availability. 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
Question
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.
