Practice - 5 Tasks

1fill in blank

easy

Complete the code to perform an ordered insert of multiple documents in MongoDB.

MongoDB

💡 Hint

Common Mistakes

Using false will make inserts unordered, which is not what is asked.

Setting ordered: true ensures documents are inserted in order, stopping at the first error.

2fill in blank

medium

Complete the code to perform an unordered insert of multiple documents in MongoDB.

MongoDB

db.collection.insertMany([{name: 'Carol'}, {name: 'Dave'}], {ordered: [1])

Drag options to blanks, or click blank then click option'

Atrue

Bundefined

Cnull

Dfalse

💡 Hint

Common Mistakes

Using true will stop inserts on the first error.

Setting ordered: false allows MongoDB to insert documents in any order and continue after errors.

3fill in blank

hard

Fix the error in the code to correctly perform an unordered insert.

MongoDB

db.collection.insertMany([{name: 'Eve'}, {name: 'Frank'}], {ordered: [1])

Drag options to blanks, or click blank then click option'

Afalse

Btrue

C0

D1

💡 Hint

Common Mistakes

Using 0 or 1 instead of boolean values causes errors.

The ordered option must be a boolean. Using false enables unordered inserts.

4fill in blank

hard

Fill both blanks to perform an unordered insert and handle errors without stopping.

MongoDB

db.collection.insertMany([{name: 'Grace'}, {name: 'Heidi'}], {ordered: [1], [2]: true})

Drag options to blanks, or click blank then click option'

Afalse

BwriteConcern

CbypassDocumentValidation

Dtrue

3 left

💡 Hint

Common Mistakes

Using true for ordered inserts when unordered is needed.

Setting ordered: false allows unordered inserts, and bypassDocumentValidation: true skips validation errors.

5fill in blank

hard

Fill all three blanks to perform an unordered insert with write concern and bypass validation.

MongoDB

db.collection.insertMany([{name: 'Ivan'}, {name: 'Judy'}], {ordered: [1], [2]: 1, [3]: true})

Drag options to blanks, or click blank then click option'

Atrue

BwriteConcern

CbypassDocumentValidation

Dfalse

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing ordered true/false and missing writeConcern option.

Use ordered: false for unordered inserts, writeConcern: 1 to confirm writes, and bypassDocumentValidation: true to skip validation.
