In this case, the Cursor is a MongoDB Collection of the document that is returned as a result of the find method being executed. By default, it is automatically executed as a loop, which is undesirable. We can, on the other hand, request a specific index document from the cursor that was returned. It works in the same way as a pointer those points to a specific index value in a database.

Discuss this Question


15. Field is a name-value pair in a ___.

  1. Attribute
  2. Table
  3. Document
  4. None of the mentioned above

Answer: C) Document

Explanation:

A field in a document is a name-value pair that contains information. There are zero or more fields in a document. Fields in relational databases are analogous to columns in traditional databases. In MongoDB, each document stored in a collection is identified by a unique _id field, which serves as the collection's primary key. If the _id field is not present in an inserted document, the MongoDB driver creates an ObjectId for the _id field by generating it automatically.

16. MongoDB supports searching by ___.

  1. Field
  2. Range queries
  3. Regular expression searches
  4. All of the mentioned above

Answer: D) All of the mentioned above

Explanation:

Ad hoc queries in MongoDB are supported by searching by field, range queries, and regular expression searches, among other search options. In order to return specific fields within documents, queries can be created. Ad-hoc queries are those that were not anticipated when the database was being built. Consequently, MongoDB provides ad-hoc query support, which distinguishes it from other databases in this situation. Ad-hoc queries are updated in real time, resulting in a significant improvement in the performance of the system.

Discuss this Question


17. Indexes can be created to improve the performance of searches within ___.

  1. MongoDB
  2. NoSQL
  3. Both A. and B.
  4. None of the mentioned above

Answer: C) Both A. and B.

Explanation:

Indexes can be created in MongoDB to improve the performance of searches in the database. Any field in a MongoDB document can be indexed, including the document's name. When using MongoDB, indexes are used to speed up the execution of queries. Due to the lack of indexes, MongoDB is forced to perform a collection scan, which is to say it must scan each and every document in a collection, in order to select the documents that match the query statement. Whenever a query is associated with an appropriate index, MongoDB can use the index to reduce the number of documents that must be inspected by the query.

Discuss this Question


18. MongoDB can provide high availability with replica sets?

  1. True
  2. False

Answer: A) True

Explanation:

MongoDB can provide high availability through the use of replica sets. A replica set is made up of two or more instances of the mongo DB. Each member of the replica set has the ability to take on the role of either the primary or secondary replica at any time. Essentially, the primary replica is the main servers that interacts with the client and performs all read and write operations on their behalf. Built-in replication is used by the secondary replicas to keep a copy of the data from the primary replicas.

Discuss this Question


19. The data in MongoDB has a flexible schema?

  1. True
  2. False

Answer: A) True

Explanation:

The data in MongoDB has a flexible schema. Unlike SQL databases, where you must first declare the schema of a table before you can insert data, MongoDB's collections do not enforce document structure before you can insert data. This type of adaptability is what distinguishes MongoDB as a powerful database.
