Tenants in a shared datacenter environment are concerned with the privacy of their data as it moves from the application to the database servers in clear text. Which of the following can the provider

Bandwidth hard limits control the maximum network throughput for a tenant but do not provide logical isolation or prevent one tenant's clear-text data from being potentially visible to another on the same network segment.

Reservations guarantee a specific amount of computing resources for a tenant but do not address network segmentation or the privacy of data transmitted over the network.

Resource pooling aggregates physical resources for shared consumption but does not provide network isolation or data privacy between the resources utilized by different tenants.

VLANs (Virtual Local Area Networks) segment a single physical network into multiple logical broadcast domains, effectively isolating traffic between different tenants even when they share the same physical infrastructure, thus enhancing data privacy and security for data moving in clear text.
