What is the command to filter a metric where the tag 'team' starts with `tps` and ends with `is_the_best`?

The command to filter a metric with a tag that starts with tps and ends with is_the_best is correctly represented by the choice that uses the wildcard character appropriately.

In Datadog, the asterisk (*) is used as a wildcard in tag queries. To express that a tag value starts with a specific substring, the wildcard should be placed at the end of that substring. Therefore, tps* indicates that the tag value can be anything that begins with 'tps'.

For the condition where the tag ends with is_the_best, the wildcard is placed at the start of the substring, resulting in *is_the_best. This configuration allows for any characters to precede 'is_the_best', thus effectively filtering for any tag value that concludes with this string.

The correct choice combines these two conditions into one single filter command: my_metric{team:tps*,team:*is_the_best}. This filters the my_metric metric for tags that match both criteria: starting with 'tps' and ending with 'is_the_best'.

The other options either incorrectly position the wildcards or do not utilize them in a way that accurately reflects the requirements of both conditions.
