With finite resources available within a cloud, even the largest cloud providers will at times need to determine which customers will receive additional resources first. What is the term associated with this determination?
When cloud resources are finite, providers use "shares" to determine which customers receive additional resources. This concept involves assigning a relative priority (or weight) to each customer so that, in times of resource contention, the customer with a higher share value gets additional resources before others.
While terms like weighting or prioritization might seem similar, "shares" is the precise term used in cloud resource management for this purpose.
C. Share. CBK Reference: Share is a weighting given to a particular VM that is used to calculate percentagebased access to pooled resouces when there is a contention.
The correct answer is B. Prioritization. In a cloud environment, resources are often shared among many different customers. When there is not enough capacity to meet the demands of all customers at the same time, the cloud provider must decide which customers will receive additional resources first. This process of determining which customers will receive additional resources first is called prioritization.
Seems like the question asks for terminology. "Shares" is a defined term in this context - "priorisation" is the desired effect, but not defined as the term for what is described.
Shares: The concept of shares is used to arbitrate the issues associated
with compute resource contention situations. Resource contention
implies that there are too many requests for resources based on the
actual available amount of resources currently in the system. If resource
contention takes place, share values are used to prioritize compute
resource access for all guests assigned a certain ratio of shares. The
shares are weighed and used as a percentage against all outstanding
shares assigned and in use by all powered-on guests to calculate the
amount of resources each individual guest will be given access to. The
higher the share value assigned to a guest, the larger the percentage of
the remaining resources that guest will be given access to during the
contention period
This is the strangest question. Shares have weighting which determines the prioritization so hope you guess correctly.
