    GCP PCA · Question 49 · Domain 5: Managing Implementation and Ensuring Reliability

    You are defining the reliability metrics for a new API service according to Google's SRE practices. Which TWO statements correctly define the relationship between Service Level Indicators (SLIs) and Service Level Objectives (SLOs)? (Select TWO)

    Answer options:

    A.

    An SLI is a quantitative measure of a specific aspect of the service's performance, such as latency or error rate.

    B.

    An SLO is the legal contract signed with the customer guaranteeing uptime.

    C.

    An SLO is a target value or range of values for a service level that is measured by an SLI.

    D.

    SLIs should always be set to 100% to ensure maximum reliability.

    E.

    The Error Budget is calculated by adding the SLI to the SLO.

    How to approach this question

    Remember the SRE definitions: SLI = the Metric. SLO = the Target. SLA = the Contract.

    Full Answer

    A,C
    In Site Reliability Engineering (SRE), terminology is strict. A Service Level Indicator (SLI) is a carefully defined quantitative measure of some aspect of the level of service that is provided (e.g., request latency, error rate). A Service Level Objective (SLO) is a target value or range of values for a service level that is measured by an SLI (e.g., 99.9% of requests will succeed). The SLA is the business contract that dictates what happens if the SLO is missed.

    Common mistakes

    Confusing SLO with SLA (B). SRE teams manage SLOs. Lawyers and business teams manage SLAs.
