QUESTION: 45

You support a high-traffic web application and want to ensure that the home page loads in a timely manner. As a first step, you decide to implement a Service Level Indicator (SLI) to represent home page request latency with an acceptable page load time set to 100 ms.
What is the Google- recommended way of calculating this SLI?

Buckelize Ihe request latencies into ranges, and then compute the percentile at 100 ms.
Bucketize the request latencies into ranges, and then compute the median and 90th percentiles.
Count the number of home page requests that load in under 100 ms, and then divide by the total number of home page requests.
Count the number of home page requests that load in under 100 ms. and then divide by the total number of all web application requests.

Answer(s): C

Explanation:

In the SRE principles book, it's recommended treating the SLI as the ratio of two numbers: the number of good events divided by the total number of events. For example: Number of successful

HTTP requests / total HTTP requests (success rate)

QUESTION: 48

You support a stateless web-based API that is deployed on a single Compute Engine instance in the europe-west2-a zone . The Service Level Indicator (SLI) for service availability is below the specified Service Level Objective (SLO). A postmortem has revealed that requests to the API regularly time out. The time outs are due to the API having a high number of requests and running out memory. You want to improve service availability.
What should you do?

Change the specified SLO to match the measured SLI.
Move the service to higher-specification compute instances with more memory.
Set up additional service instances in other zones and load balance the traffic between all instances.
Set up additional service instances in other zones and use them as a failover in case the primary instance is unavailable.
