Objects that require more server-side bandwidth and response time are likely to be deleted from the cache. This statement best describes which ProxySG caching technique?

The statement correctly identifies cost-based deletion as a caching technique that prioritizes the management of cache storage based on the server-side bandwidth and response time of the objects. In this context, cost-based deletion evaluates the "cost" of keeping certain objects in the cache, which is determined by how resource-intensive they are in terms of server-side bandwidth usage and response time for retrieval.

When an object demands significant resources to serve requests, it is considered to impose a higher "cost" on the system. Therefore, these costly objects are more likely to be removed from the cache to free up space for more efficient or low-cost items that can be served quickly and with less bandwidth. This strategy allows the proxy to maintain optimal performance and resource management by ensuring that the cache contains predominantly objects that balance speed and resource usage.

Other options might focus on different criteria for cache management, such as the recency of access or predetermined time limits, but they do not specifically consider the impact of server-side resource demands in the way that cost-based deletion does.
