NEW QUESTION # 67
What is the purpose of enabling TLS?
Answer: A
Explanation:
Transport Layer Security protects MongoDB network communications while data travels between clients and servers and, when configured, between MongoDB deployment members. Its core purpose is therefore encryption of data in transit. TLS helps prevent passive interception and tampering and also supports certificate-based identity validation. It is separate from encryption at rest, which protects files on storage media, and separate from Queryable Encryption or client-side field encryption, which protects selected application data before it reaches the server. Option A is unrelated: backup and restore operations use snapshot, managed backup, or database-tool mechanisms. Option B describes the objective of replication, elections, and redundant deployment architecture, not TLS. Option C is also incorrect; TLS is a security control, not a query-optimization mechanism, and cryptographic processing can add some overhead rather than improving query execution. A secure MongoDB deployment normally combines TLS with strong authentication, least-privilege authorization, appropriate network exposure controls, auditing, and storage or field-level encryption as required. For the specific question, enabling TLS provides encryption for data moving across the network, making option D correct.

NEW QUESTION # 68
A collection named products contains the following documents:
{ " _id " : 1, " name " : " Laptop " , " price " : 1500 }
{ " _id " : 2, " name " : " Smartphone " , " price " : 800 }
{ " _id " : 3, " name " : " Tablet " , " price " : 600 }
{ " _id " : 4, " name " : " Monitor " , " price " : 300 }
{ " _id " : 5, " name " : " Headphones " , " price " : 200 }
Given the following query:
db.products.find().sort({ " price " : -1 }).limit(2)
What is the expected output?
Answer: A
Explanation:
The query first applies .sort({ price: -1 }). In MongoDB, -1 specifies descending order, so the result stream is ordered from the highest price to the lowest: Laptop at 1500, Smartphone at 800, Tablet at 600, Monitor at
300, and Headphones at 200. The subsequent .limit(2) restricts the cursor to the first two documents in that sorted sequence. Therefore, only Laptop and Smartphone are returned. Option B identifies the two lowest- priced products rather than the highest. Option C reflects the sort but ignores the limit(2) stage. Option D shows the two lowest products in ascending order and therefore contradicts both the requested sort direction and the limit semantics. For a large collection, a single-field index on price could support this sort efficiently because MongoDB can traverse an index in either direction; an ascending index can be scanned backward to satisfy a descending sort and vice versa. The logical query result, however, is independent of whether such an index exists. Option A is the correct output.
