[All Professional Cloud DevOps Engineer Questions]

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?

ABuckelize Ihe request latencies into ranges, and then compute the percentile at 100 ms.

BBucketize the request latencies into ranges, and then compute the median and 90th percentiles.

CCount the number of home page requests that load in under 100 ms, and then divide by the total number of home page requests.

DCount the number of home page requests that load in under 100 ms. and then divide by the total number of all web application requests.

Suggested Answer: C

https://sre.google/workbook/implementing-slos/

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)

Bucketing latencies is good, but I prefer the median approach.

Wait, are we really counting all requests for D? Seems off.

Counting requests under 100 ms sounds right, but I wonder if we should only focus on the home page or all requests.

I feel like the median and percentiles are important, but I can't recall if they relate to the SLI calculation directly.

I remember practicing a similar question where we had to calculate SLIs, and I think bucketizing latencies was involved.

I think we should count the requests that load under 100 ms, but I'm not sure if it's option C or D.

Easy peasy, the answer is A - a Subscription. That's the top-level Azure resource that all your other services and resources have to be associated with. I'm feeling pretty confident about this one.

This looks like a straightforward data extension setup question. I think the key is to identify the primary key and make sure the data extension is sendable.

This looks like a pretty straightforward question. I think the key is to create a new domain that only contains the NetWare servers I manage, and then use that domain in the Management Console. Option C seems to be the best approach.
