Which of the following internet service types is delivered using an SFP connector?
Correct Answer: A
Fiber internet uses SFP (Small Form-factor Pluggable) connectors to interface optical fiber cables with network equipment.
Question 2
Which of the following is used to measure the speed of a CPU?
Correct Answer: A
CPU speed is measured in megahertz (MHz) or gigahertz (GHz), indicating how many million or billion cycles the processor can execute per second. "CPU performance is commonly measured in megahertz (MHz) or gigahertz (GHz), representing the processor's clock speed." - CompTIA ITF+ MB is for memory/storage size. Mbps is for network speed. MAC is a hardware address, not a performance metric. Correct answer: A
Question 3
A user purchases a new router and wants to configure it. Which of the following should the user change first?
Correct Answer: D
Changing the default password first secures the router against unauthorized access before any other configuration is applied.
Question 4
A systems administrator requires access to a user's laptop over a VPN for troubleshooting. Which of the following software types should the systems administrator use?
Correct Answer: D
Remote assistance software allows a systems administrator to remotely access and control a user's device, especially over a VPN, for troubleshooting and support.
Question 5
Which of the following is true with respect to a flat file and a database?
Correct Answer: C
The correct answer is C. Databases provide better data organization, indexing, and querying. A flat file is a two-dimensional structure made of rows and columns, such as a simple spreadsheet. Databases are better for larger, more complex, multiuser, scalable, searchable data systems. Databases can manage relationships between data points, support queries and reports, and provide stronger data persistence, availability, and security. A flat file does not represent a relational system, and query languages are associated with databases rather than basic flat files. Exact Extract/Reference: The Tech+ Study Guide explains that a flat file has "two dimensions, rows and columns," while databases can "manage far more complicated relationships between data points." It also states that databases are better when multiple users, large quantities of data, speed, scalability, data persistence, data availability, and security matter. The guide further states that databases can be queried and reports can be run from them.
