Question #1
Service Level Indicator data helps to understand how much Error Budget is left. TRUE or FALSE?
Please select an optionIncorrectCorrect answer: A
SLI measurements are compared against the SLO, and the gap between actual performance and the objective is exactly what consumes or leaves the error budget.
Was this answer correct?Question #2
Which type of engineering work will reduce toil within the service?
Please select an optionIncorrectCorrect answer: D
Toil is reduced by internal automation built into the service itself, so the manual, repetitive work disappears permanently rather than being handled by external scripts or people.
Was this answer correct?Question #3
Which of the following BEST describes capacity planning?
Please select an optionIncorrectCorrect answer: C
Capacity planning is the set of activities producing a plan for managing resources so that current and forecast service demand can be met; monitoring utilisation is only an input to that plan.
Was this answer correct?Question #4
Which of the following BEST describe the characteristics of a product team? • They are small and collaborative • They have cross-functional skillsets • They do not share responsibilities • They discourage any feedback
Please select an optionIncorrectCorrect answer: A
Product teams are small, collaborative and cross-functional; they explicitly share responsibility and actively seek feedback, so statements 3 and 4 are wrong.
Was this answer correct?Question #5
Which of these approaches can alleviate linear scaling toil?
Please select an optionIncorrectCorrect answer: B
Linear scaling toil means operational effort grows in step with the service; auto-scaling removes the manual provisioning work so effort no longer scales with demand.
Was this answer correct?Question #6
Which of the following is the LEAST useful metric when working to improve antifragility?
Please select an optionIncorrectCorrect answer: C
Antifragility is about detecting, withstanding and recovering from failure, measured by MTTD, SLOs and RPO; deployment frequency measures delivery throughput, not how well the system gains from stress.
Was this answer correct?Question #7
Who codifies software-defined networks (SDNs) and applies SDLC principles to build, test and deploy network changes?
Please select an optionIncorrectCorrect answer: B
The Network Reliability Engineer applies software engineering and SDLC discipline to software-defined networks, building, testing and deploying network changes as code.
Was this answer correct?Question #8
Which of the following BEST defines the golden signal for errors?
Please select an optionIncorrectCorrect answer: B
The errors golden signal is the rate of failed requests, whether they fail explicitly, implicitly (a wrong response returned as success) or by policy; latency, traffic and saturation cover the other options.
Was this answer correct?Question #9
A team has exceeded their error budget by 10% in a particular month. Give an example of what should happen next as a consequence.
Please select an optionIncorrectCorrect answer: A
Exceeding the error budget triggers a freeze on new features: work shifts to reliability, so sprint planning pulls only post-mortem and remediation items until the budget is restored.
Was this answer correct?Question #10
What is one of the key characteristics of a Service Level Indicator (SLI)?
Please select an optionIncorrectCorrect answer: C
An SLI must be measured over a defined time horizon or window, otherwise the value cannot be compared to an objective or used to compute the error budget.
