3.4MHz

This is not measuring processing speed.
It's measuring throughput.

5000Kbps

Gig is larger that Mega.
G>M

• IMAP

• POP3

• FTP

• SMTP

Simple Mail Transfer Protocol

Protocol for downloading emails from a mail server.

Multiple Choice

A new device has been installed on a wired network and can be accessed via the LAN but cannot be accessed remotely.

Which of the following is the most likely cause?

• Improper Switch configuration

• Firewall settings

• Incorrect IP Address

• Misconfigured Access Point

Firewall settings.

Firewalls act as security barriers, controlling incoming and outgoing traffic.
If the firewall settings are not configured to allow remote access to the specific device (through port forwarding or specific rules), it would be accessible within the local network (LAN) but not from outside.

Firewall settings.

If the IP for the new device was incorrect, it also wouldn't work on the LAN.

IP Address

Connects devices together on a LAN. If this wasn't configured right, the new device wouldn't work locally either.

Switch

The Q states the new device is on a WIRED network. Access Points are for wireless networks.

Access Point

Multiple Choice

• DIMM

• DDR

• RAM

• ROM

ROM.

Dual In Line Memory Module. Type RAM.
Volatile.

DIMM

Volatile memory. Loses data without power.

RAM

Double Data Rate.
Also a type of RAM.
Volatile.

DDR

Read Only Memory. Stores permanent data such as BIOS. Non-Volatile.

Multiple Choice

A user browses to a website. Before the page opens, the user receives a message that the site is not secure. Which of the following caused this message?

• Proxy

• Script

• Malware

• Certificate

Certificate.

Malicious scripts could be a threat but would not cause the security warning.

Script

Can affect how a user connects to a website but does not trigger a "not secure" message.

Proxy

Browsers typically warn about insecure web sites before malware gets installed.

Malware

The "not secure" message is often displayed because the website doesn't use a valid SSL/TLS certificate

Multiple Choice

Which of the following software solutions ensures that programs running simultaneously on a workstation do not utilize the same physical memory?

• Operating System

• Anti-Malware

• Disk Optimizer

• Type 1 Hypervisor

Operating System.

Focuses on improving the performance of your hard drive, not memory management

Disk optimizer

protects against malicious software, but does not manage memory allocation between programs.

anti-malware

Manages memory within virtual machines but not responsible for memory on workstations

Type 1 Hypervisor

The OS will assign and distribute hardware resources to each application.

Multiple Choice

A user inserts a USB flash drive into a computer for the first time and sees a message on the screen indicating the device is being set up. The message quickly changes to indicate the device is ready for use. Which of the following device configuration types most likely occurred?

• Web-based

• IP-based

• Plug-and-play

• Driver Installation

Plug-and-Play (PnP)

Typically used for network devices, not storage devices

ip-based

Allows more extensive setup where user interacts with a web interface.

web-based

While Plug-and-Play does usually install a driver, it does more than just driver installation.

Driver Installation

Uses pre-installed generic drivers to recognize and configure basic functionality for most USB devices.

Multiple Choice

Which of the following describes the concept of a database record?

• A collection of schemas within the same database

• A collection of tables within different schemas

• A collection of fields about the same object

• A collection of rows, columns, and constants

Multiple Choice

Which of the following is an advantage of a flat file?

• scalability

• variety of data

• multiple concurrent users

• portability

Portability.

Flat Files usually store data in a single format rather than a variety

variety of data

Flat files become more difficult to manage as the data grows. This would be a benefit to a Relational Database

scalability

Having multiple users accessing a flat file at the same time can result in corruption

Multiple concurrent users

Portability is a key strength of flat files. They are simple and can easily be transferred between different computer systems
