Tech+ Review Part 6

Which term describes the phase in disaster recovery that involves re-establishing user interactions, processing, and operations with IT systems following a disruptive incident?

• System reconfiguration

• Data replication

• Account recovery

• Restoring access

Answer explanation

Explanation:
“Restoring access” is the step where systems are brought back online so people can actually log in, run programs, and carry on.

Real-world scenario:
Imagine your favorite online game’s servers crash during an update. Once the engineers fix the code and turn the servers back on, you can log in and play again—that’s “restoring access.”

Which of the following is best described as a markup language used to create and format documents on the World Wide Web?

• JSON

• SQL

• HTML

• XML

Answer explanation

Explanation:
HTML (HyperText Markup Language) uses tags like <h1> and <p> to structure text, images, and links on web pages.

Real-world scenario:
Think of HTML like the headings and bullet points in your homework: it tells the browser how to lay out titles, paragraphs, and pictures on a website.

Which of the following is the BEST example of a markup language used to structure and format content on webpages?

• Python

• Java

• Hypertext Markup Language (HTML)

• Cascading Style Sheets (CSS)

Answer explanation

Explanation:
While XML is a data-storage markup, HTML is specifically designed for laying out pages. CSS controls style (colors, fonts), not structure.

Real-world scenario:
If a webpage were a sandwich, HTML would be the bread and fillings arranging your content, CSS would be the spices and sauces making it look tasty.

Your company is seeking to improve employee experience by reducing the number of times users need to authenticate when accessing various internal services throughout the day. Which feature would be most effective to implement while considering access-control best practices?

• Lightweight Directory Access Protocol (LDAP) implementation

• Single Sign-On (SSO) feature

• Kerberos authentication

• Password manager integration

Answer explanation

Explanation:
SSO lets you log in once and gain access to multiple apps without re-entering credentials each time.

Real-world scenario:
Like having one key that opens your front door, school locker, and bike lock—no juggling five different keys every day.

Which type of programming language requires a specific type of assembler to convert its instructions into machine code for execution on a particular type of CPU?

• Assembly language

• Query language

• High-level programming language

• • Interpreted language

Answer explanation

Explanation:
Assembly language is written in mnemonics (e.g. MOV R1, #5) and an assembler translates it into CPU-specific machine code.

Real-world scenario:
It’s like a secret code that only one model of robot can understand—you need the exact translator for that robot’s brain.

Executing the DROP command on a table will also remove all records stored within that table.

• True

• False

Answer explanation

Explanation:
DROP TABLE deletes the entire table structure and its data; you can’t recover rows unless you have a backup.

Real-world scenario:
Imagine ripping out a page from your notebook—with DROP, not only do the words disappear, the page itself is gone forever.

When connecting a monitor to a desktop computer, which option will BEST support an analog video connection?

• Mini DisplayPort connector

• VGA connector

• DisplayPort connector

• HDMI connector

Answer explanation

Explanation:
VGA transmits analog signals (varying voltages), while HDMI/DisplayPort carry digital data (0s and 1s).

Real-world scenario:
It’s like plugging old wired headphones (VGA) into a phone jack versus using Bluetooth (digital) headphones—VGA is strictly analog.

In a company, you need to add a new record for a recently hired employee into the employee database. Which command should you use to accomplish this task?

• INSERT

• CREATE

• UPDATE

• SELECT

Answer explanation

Explanation:
INSERT adds new rows to an existing table. CREATE makes new tables, UPDATE changes existing rows, and SELECT only reads data.

Real-world scenario:
Think of a spreadsheet: INSERT is like adding a new row with a new student’s info.

Which of the following allows the adjustment of properties of system services, including their startup types or disabling them entirely?

• Services console

• Task Scheduler

• Device Manager

• Programs and Features

Answer explanation

Explanation:
The Services console in Windows lists background services and lets you start/stop them or set them to automatic/manual/disabled.

Real-world scenario:
Like a remote-control panel for every background app on your PC—turn them on or off and choose when they run.

An IT professional is setting up a new server that will run an open-source operating system. The server needs a robust file system capable of handling large files and large volumes of small files while providing journaling capabilities to maintain data integrity. Which file system should the IT professional consider using?

• Ext4

• Ext3

• FAT32

• NTFS

Answer explanation

Explanation:
Ext4 (on Linux) supports big files, many small files, and journaling (it logs changes before applying them, helping recover after crashes).

Real-world scenario:
Imagine Ext4 as a library with an index card system that not only tracks every book you add or remove but writes down planned changes before shelving them—so if someone bumps a shelf, you can quickly fix where books belong.
