DOption D

EOption E

Show Suggested Answer

Suggested Answer: A, C

The task is to identify unwanted incoming web service calls during the last seven days. To do this, we need to look at KQL (Kusto Query Language) queries that would filter out web service calls based on the timestamp (to ensure the calls are within the last seven days) and by certain characteristics that would indicate they are unwanted, such as the wrong type of protocol (SOAP in this case, as Contoso Ltd. plans to dismiss using it).

Looking at the options:

Option A: This query selects all traces where the timestamp is within the last 7 days and where the custom dimension has a value of 'RT0008', and where the category is either 'ODataV4', 'ODataV3', or 'Api'. This query would show all API calls except SOAP, so it does not directly answer the question about unwanted calls.

Option B: This query filters for traces with a timestamp within the last 7 days, where 'RT0008' is present, and specifically looks for the category 'SOAP'. This query is correct because it directly targets SOAP calls, which are the unwanted calls according to Contoso Ltd.'s plans.

Option C: Similar to option B, this query filters for traces within the last 7 days and looks for 'RT0008' but uses the equality operator for the category 'SOAP'. This would also correctly return the unwanted SOAP calls.

Option D: This query also filters for traces within the last 7 days, but it excludes the 'ODataV4' category, which doesn't necessarily target the unwanted SOAP calls.

Option E: This query selects traces where the timestamp is within the last 7 days and the custom dimension has 'RT0008'. However, it filters out categories 'ODataV4' and 'Api', which does not directly help in identifying the unwanted SOAP calls.

Therefore, the queries that should be used to determine if there are unwanted incoming web service calls (SOAP calls) in the tenant during the last seven days are Options B and C. These queries are specific to identifying SOAP protocol usage, which is what Contoso Ltd. considers unwanted.

I thought we only needed to check the last 24 hours?

Wait, are we really checking for calls in the last seven days?

I remember something about using specific fields in the KQL queries, but I can't quite remember if it's option C or E that uses them correctly.

I feel like option A has the right syntax for filtering, but I'm a bit confused about how to check for unwanted calls specifically.

I practiced a similar question where we had to identify unwanted calls, and I think options B and D might be the right ones, but I can't recall the specifics.

I think I remember that we need to filter the logs for the last seven days, but I'm not sure which query structure is best for that.

I feel pretty confident about this question. The key is to identify the KQL queries that will provide the most relevant information to detect unwanted web service calls within the specified time frame. I think Options A and D are the way to go.

Okay, I think I've got a handle on this. Based on the requirement to identify unwanted incoming web service calls in the last seven days, I'd say Options A and B look like the most promising solutions.

Hmm, I'm a bit unsure about this one. The question is asking for two KQL queries, but there are multiple options provided. I'll need to analyze each one closely to figure out the best combination.

This looks like a straightforward KQL query question. I'll need to carefully review the options and think through the logic to determine the correct queries.

This is a tricky one. I'm not super familiar with KQL, so I'll need to really focus on understanding the syntax and logic behind each of these options. I'll make sure to read through the details carefully.

Okay, this makes sense to me. Distributed computing is all about dividing up the work and then combining the results, so TRUE is the right answer here.

That's a good point, France. Option D could be a good alternative to consider as well.

Hold up, did someone say web service calls? I thought this was a quiz on how to brew the perfect cup of coffee. Anyway, I'm gonna go with Option C, just to keep things interesting.
