Cloud Digital Leader Why Cloud Technology Can Transform Business Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Network egress charges

  Why it's wrong here

  These are costs incurred when data leaves a cloud provider's network, e.g., per-GB transfer fees. For an on-premises data center, traffic moves over privately owned or leased lines, and there is no per-byte egress metering from a hyperscaler. Therefore, it is not a core component of on-prem TCO, though it is a significant variable in cloud total cost.

• ✗

  Software licensing fees

  Why it's wrong here

  While software licenses are a real cost, they often follow similar pricing across on-prem and cloud, with cloud-specific options like bring-your-own-license (BYOL). They are not a differentiating cost driver in the TCO comparison; the major differentiators are infrastructure capital and operational expenses like hardware, staff, and facilities. Licensing costs would be included but are roughly equivalent, so they don't change the decision.

• ✓

  Staff salaries for data center operations

  Why this is correct

  Personnel costs for managing, patching, securing, and monitoring servers, network gear, storage, and virtualization layers are a substantial operational expenditure. Unlike cloud environments, where the provider absorbs many labor tasks, on-prem TCO must fully account for the salaries of administrators, engineers, and support staff. This is often one of the largest hidden OpEx categories in a data center budget.

• ✓

  Hardware purchase and depreciation

  Why this is correct

  On-prem TCO must include the capital expense of acquiring servers, storage arrays, and networking equipment, as well as the annual depreciation expense over their useful life. This is a primary cost driver that is often eliminated or converted to an operating expense (such as reserved instances) in the cloud. Hardware also involves periodic refresh cycles that significantly impact multi-year total cost.

• ✓

  Power and cooling costs

  Why this is correct

  The operational cost of electricity for IT equipment plus the HVAC and cooling infrastructure needed to dissipate heat is a significant recurring expense in a data center. Cloud providers bundle these costs into their service pricing, but an on-prem TCO calculation must explicitly itemize them, including the effects of power usage effectiveness (PUE). Cooling can account for up to 30-40% of a data center's total energy consumption.
