08.Ask Precise Questions

Answer each question with one command. Start from the full JSON and narrow it:

aws ec2 describe-regions --output json
aws ec2 describe-regions --query "length(Regions)"
aws ec2 describe-availability-zones --query "AvailabilityZones[?ZoneName=='us-east-1b'].ZoneId" --output text
aws ec2 describe-regions --query "Regions[?starts_with(RegionName, 'eu')].RegionName" --output text

Finish with a table of zone names and ids built with curly braces.
