Which of the following is a consequence of poor high availability planning?

In the context of high availability planning, the consequence of poor planning often leads to increased downtime during maintenance. This is because inadequate strategies may fail to ensure that systems remain operational during maintenance activities or unforeseen outages. High availability is crucial for applications and services that require minimal downtime for uninterrupted user access. A poorly planned high availability strategy might overlook redundancy, load balancing, or the implementation of failover mechanisms, which are essential for maintaining availability during maintenance tasks. As a result, when maintenance is required, users may experience increased downtime, disrupting service and potentially leading to loss of data or revenue.

The other options reflect positive outcomes rather than consequences of poor planning. Improved user experience, enhanced resource allocation, and more effective data management are all indicators of successful high availability strategies rather than the result of shortcomings in planning. Proper high availability planning aims to minimize downtime and optimize service continuity, which directly impacts user satisfaction and operational efficiency.
