Cloud Digital Leader Why cloud technology is transforming 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.

• ✓

  On-demand provisioning that allows infrastructure to be deployed in minutes rather than waiting months for hardware procurement and installation

  Why this is correct

  On-demand self-service is the cloud characteristic that most directly removes the hardware procurement bottleneck. By provisioning infrastructure in minutes, telecoms can test, iterate, and launch new services at a pace impossible with traditional infrastructure cycles.

• ✗

  The ability to store large amounts of customer call records in the cloud at lower cost

  Why it's wrong here

  Storing call detail records at lower cost is a financial optimization tied to compliance and analytics workloads that run after a service is already in production. It is a back-office efficiency, not a capability that helps a telecom build, test, and launch a new 5G network function or slice more quickly. The question asks what directly shortens the service launch timeline, and cheap storage does not affect infrastructure deployment speed or the agility of the development lifecycle.

• ✗

  Cloud providers' global data center network ensures low latency for all customer calls

  Why it's wrong here

  A global data center footprint provides capacity and redundancy, but it cannot guarantee low latency for all customer calls because the dominant latency contributors are the radio access network and the backhaul between the device, cell site, and edge node. A centralized cloud region may be hundreds of miles from the user, so without edge computing even a geographically broad network cannot consistently meet the sub-10ms targets that 5G services require. Therefore, global data center presence is not the decisive factor for accelerating new service launches.

• ✗

  Managed cloud databases that eliminate the need for database administrators

  Why it's wrong here

  Managed cloud databases reduce certain operational chores such as patching, backups, and replication, but they do not eliminate the need for database administration entirely—schema design, access control, query tuning, and performance optimization still require skilled staff. More importantly, managed databases do not address the core bottleneck of slow hardware procurement cycles. A telecom can still wait months for compute and network capacity even if database operations are simplified, so this is not the fundamental accelerator of time-to-market for new services.
