CompTIA FC0-U71 Dumps Questions Answers

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), the SFP (Small Form-Factor Pluggable) connector is directly associated with fiber-optic networking. The guide lists:

“SFP (small form-factor pluggable) connectors are commonly used in fiber-optic connections to allow hot-swappable transceivers for different types of fiber cables.”

Additionally, the same guide’s chapter on Networking Concepts and Technologies explains:

“Fiber-optic around 2 Gbps – Incredibly fast and more expensive than DSL or cable.”

Therefore, fiber Internet is the only service type that uses SFP connectors for data transmission over optical cables.

In terms of storage measurement hierarchy:

1TB = 1,000GB

1GB = 1,000MB

1MB = 1,000KB

Therefore:

20TB = 20,000GB

2,000GB = 2,000GB

200MB = 0.2GB

2,000KB = 0.002GB

Thus, 20TB is the largest. The CompTIA ITF+ FC0-U71 Official Study Guide defines storage units in this way under data representation topics.

The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) clearly states:

“If you need to have multiple concurrent users accessing data, you need a database. Flat files don’t do well when several people try to access them at once. In the vast majority of cases, one user might be able to write to the file, but all users will be limited to a read-only copy.”

It further explains that:

“Databases generally lock only on a record level (or individual line of data), so multiple people can actively use the database at one time.”

Therefore, the best reason to convert a large spreadsheet to a database is to allow multiple concurrent users to access and update the data simultaneously without conflicts.
