The VMware hot add and hot plug functionality is most useful for a(n) __________ scaling approach.
A. adaptive
B. predictive
Correct Answer: A
Explanation/Reference:
Explanation:
There are two types of scaling approaches in virtual platforms: adaptive and predictive. Both approaches are usable; however, a designer must work out which is the best approach for each project.
The adaptive approach to guest virtual machine design is a major advantage that virtualization technology brings to a datacenter. It allows a guest virtual machine to be created initially on a few metrics or high-level requirements (such as a limited budget) and scaled (that is, grown, not shrunk) through the virtual machine lifecycle. In many cases, this scaling can be performed hot/live without outage/downtime to the running applications.
The predictive approach, on the other hand, requires more planning and research, and you must know the metrics before deployment. The advantage here is that once the virtual machine has been deployed, only application maintenance is required. The application requirements are known.
