Cloud Digital Leader Why cloud technology is transforming business Practice Question

Option-by-option breakdown

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

• ✗

  Physical security of data centers

  Why it's wrong here

  Physical security of data centers is a baseline requirement for any reputable cloud provider, but it is not a transformative business benefit. Under the shared responsibility model, the provider is responsible for protecting the physical infrastructure—such as servers, storage, and networking hardware—but this is table stakes, not a capability that enables agility or innovation. Customers gaining access to a secure facility is expected and does not change how they build or scale applications, making it a prerequisite rather than a key benefit.

• ✓

  Elasticity to automatically scale resources up and down

  Why this is correct

  Elasticity is a defining benefit of cloud computing because it enables resources to automatically scale up or down in response to real-time demand. This dynamic provisioning allows businesses to handle traffic spikes without manual intervention and avoid the cost of over-provisioning for peak loads, while also ensuring consistent performance during surges. The pay-per-use model ties directly to elasticity, meaning you only pay for what you consume, which is a fundamental shift from capacity planning with fixed on-premises infrastructure.

• ✓

  Access to managed services that reduce operational overhead

  Why this is correct

  Managed services reduce operational overhead by abstracting away the undifferentiated heavy lifting of infrastructure maintenance, such as patching, backups, and high-availability failover. With services like fully managed databases or serverless compute, teams no longer need to provision or manage the underlying servers, allowing them to focus on writing code and delivering business features. This reduction in operational burden leads to faster development cycles, lower total cost of ownership, and greater innovation velocity—key reasons managed services are a core cloud advantage.

• ✗

  Data locality to keep data within national borders

  Why it's wrong here

  Data locality, the ability to keep data within specific national borders to meet regulatory requirements, is a compliance consideration rather than a transformation benefit. While cloud providers offer regional data centers and data residency options to help organizations satisfy legal obligations like GDPR or data sovereignty laws, this is a constraint-driven feature, not one that provides competitive advantage or operational efficiency. In fact, data locality restrictions can limit performance and redundancy options, so unlike elasticity or managed services, it is not a universally desirable trait.

• ✗

  Ability to purchase reserved instances for predictable workloads

  Why it's wrong here

  Purchasing reserved instances is a pricing model that offers discounted rates in exchange for a commitment to use a certain amount of capacity over one or three years, but it does not alter the fundamental capabilities of cloud technology. Reserved instances are a financial instrument for predictable workloads, enabling cost savings, but they do not provide scalability, management assistance, or any architectural advantage. Since this is purely a billing optimization, it does not represent a key benefit of cloud computing in the same way elasticity or managed services do.
