To monitor data in transit, a DLP solution would optimally be installed at the network perimeter, to ensure that data leaving the network through various protocols conforms to security controls and policies. An application server or a web server would be more appropriate for monitoring data in use, and a database server would be an example of a location appropriate for monitoring data at rest.

When leasing space in a data center, an organization can avoid the enormous startup and building costs associated with a data center, and can instead leverage economies of scale by grouping with other organizations and sharing costs.

Release management involves planning, coordinating, executing, and validating changes and rollouts to the production environment. Change management is a higher-level component than release management and also involves stakeholder and management approval, rather than specifically focusing the actual release itself. Availability management is focused on making sure system resources, processes, personnel, and toolsets are properly allocated and secured to meet SLA requirements. Problem management is focused on identifying and mitigating known problems and deficiencies before they occur.

Explanation
Object storage uses a flat structure with key values to store and access objects.

The Dynamic Host Configuration Protocol (DHCP) automatically configures network settings for a host so that these settings do not need to be configured on the host statically. Given the rapid and programmatic provisioning of resources within a cloud environment, this capability is crucial to cloud operations. Both DNS and its security-integrity extension DNSSEC provide name resolution to IP addresses, but neither is used for the configuration of network settings on a host.
DCOM refers to the Distributed Component Object Model, which was developed by Microsoft as a means to request services across a network, and is not used for network configurations at all.
