ITIL4F ITIL Management Practices Practice Question
What is the PRIMARY difference between an SLA and an OLA?
⚠ Common exam trap
Test-takers frequently confuse 'internal customer' with 'internal team,' leading them to choose Option B, but ITIL 4 defines OLAs as agreements between internal teams, not between the service provider and an internal customer.

Correct answer & explanation
✓
An SLA is between a service provider and a customer; an OLA is between the service provider and another internal team
The primary difference is that a Service Level Agreement (SLA) is a documented agreement between a service provider and a customer (external or internal) that defines the service level targets, while an Operational Level Agreement (OLA) is an internal agreement between the service provider and another internal team (e.g., IT operations, network team) that supports the delivery of the SLA. Option A correctly captures this distinction, as OLAs are always internal to the organization and support the SLA's commitments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
An SLA is between a service provider and a customer; an OLA is between the service provider and another internal team
Why this is correct
An SLA, or Service Level Agreement, formally establishes the agreed-upon service levels and responsibilities between a service provider and its customer, who consumes the service. Conversely, an OLA, or Operational Level Agreement, is an internal agreement between different teams or departments within the *same* service provider organization. Its purpose is to define the specific support activities and performance targets required to deliver the overall service levels committed in an SLA to the customer.
- ✗
An SLA is for external customers; an OLA is for internal customers
Why it's wrong here
This statement is incorrect because Service Level Agreements (SLAs) are not exclusively for external customers; they are frequently used for internal customers within an organization to define service expectations. While an OLA is indeed an internal agreement, it exists *between* internal support teams, not directly *for* internal customers in the same way an SLA does. OLAs ensure that internal support functions meet their commitments to deliver the overarching service.
- ✗
An SLA is a written agreement; an OLA is verbal
Why it's wrong here
The assertion that an OLA is verbal is fundamentally incorrect within IT service management best practices. Both Service Level Agreements (SLAs) and Operational Level Agreements (OLAs) are formal, documented agreements that must be written and signed by all involved parties. Written agreements are crucial for clarity, accountability, and providing a verifiable record of commitments and expectations, preventing misunderstandings and ensuring consistent service delivery.
- ✗
An SLA defines responsibilities; an OLA defines penalties
Why it's wrong here
This option misrepresents the primary purpose of both agreement types. While both SLAs and OLAs define responsibilities and performance targets, an OLA's core function is to outline the internal support activities and commitments necessary to meet the external SLA. Although consequences for non-compliance might be discussed, defining penalties is not the sole or primary purpose of an OLA, nor is it absent from SLAs, which often include remedies for service failures.
