Lab 4.1

In this lab you're going to use the equality, sort, range rule to determine which index best supports a given query.
Given the following query:
db.accounts.find( { accountBalance : { $gte : NumberDecimal(100000.00) }, city: "New York" } )
           .sort( { lastName: 1, firstName: 1 } )
Which of the following indexes best supports this query with regards to the equality, sort, range rule.

Choose the best answer.

Lab 2.1

In this lab you're going to determine which queries are able to successfully use a given index for both filtering and sorting. Given the following index: {"first_name": 1, "address.state": -1, "address.city": -1, "ssn": 1} Which of the following queries are able to use it for both filtering and sorting? Check all that apply: Answer: db.people.find({ "first_name": { $gt: "J" } }).sort({ "address.city": -1 }) - No - This query doesn't use equality on the index prefix. When using an index for filtering and sorting the query must include equality conditions on all the prefix keys that precede the sort keys. Moreover, on the sort predicate it skipped the next key in the prefix "address.state". db.people.find({ "first_name": "Jessica" }).sort({ "address.state": 1, "address.city": 1 }) - Yes . This query matches with equality on the query predicate wit

Given the following indexes: { categories: 1, price: 1 } { in_stock: 1, price: 1, name: 1 } The following documents: { price: 2.99, name: "Soap", in_stock: true, categories: ['Beauty', 'Personal Care'] } { price: 7.99, name: "Knife", in_stock: false, categories: ['Outdoors'] } And the following queries: db.products.find({ in_stock: true, price: { $gt: 1, $lt: 5 }  }).sort({  name: 1 }) db.products.find({ in_stock: true }) db.products.find({ categories: 'Beauty'  }).sort({  price: 1 }) Whic h of  following is/are true? Answer: Index #1 would provide a sort to query #3. - True Index #2 properly uses the equality, sort, range rule for query #1. - False - If we were to build an index for query #1 using the equality, sort, range rule, then the index would be: { in_stock: 1, name: 1, price: 1 }. There would be a total of 4 index keys created across all of these documents and indexes. - False - As there would be 5 to
