Title: Lesson 11: Quiz
Course: RITA MC - ITNW 1308 > Section: Lesson 11: Configuring and Maintaining Network Security

Q: What term is given to software that includes viruses, Trojan horses, worms, spyware, and adware?
- Scareware
- Malware
- Phishing
- Bloatware
A: Malware
Feedback: Malicious software, created specifically for the purpose of infiltrating or damaging a computer system without the user’s knowledge or consent, includes a variety of technologies such as viruses, Trojan horses, worms, spyware, and adware. The term most commonly used to collectively refer to these malicious software technologies is malware.

Q: In most cases, how is malware introduced into a computer system?
- Through a deliberate act of a bad actor (attacker)
- Through an accidental act of the computer’s user
- Through a deliberate act of the computer’s user
- Through an accidental act of a bad actor (attacker)
A: Through a deliberate act of the computer’s user
Feedback: Malware is, in most cases, introduced onto a computer by a deliberate action on the part of a user. Someone opens an email attachment, installs an infected program, or accesses a dangerous web site, and the malicious code is introduced to the system.

Q: Which of the following items is not found in the Security section of the Windows 8.1 Action Center?
- Virus Protection
- Automatic maintenance
- Network firewall
- Windows SmartScreen
A: Automatic maintenance
Feedback: The Security section, in addition to monitoring the computer’s security status, provides users with a single point of access to information about Windows 8.1 security, in the form of the following indicators: - Network firewall - Windows Update - Virus Protection - Spyware and unwanted software protection - Internet security settings - User Account Control - Windows SmartScreen - Network Access Protection - Windows activation

Q: The Windows Firewall in Windows 8.1 can have rules configured that allows traffic to flow in which direction(s)?
- Either inbound or outbound, but not both
- Only inbound
- Both inbound and outbound
- Only outbound
A: Both inbound and outbound
Feedback: Windows Firewall protects Windows 8.1 computers by blocking dangerous traffic, both incoming and outgoing. A firewall is a software program or hardware device that protects a computer by allowing certain types of network traffic in and out of the system while blocking others.

Q: Which of the following is not an item that can be used when building Windows Firewall rules?
- IP addresses of computers
- Protocol numbers
- Packet sequence numbers
- Port numbers
A: Packet sequence numbers
Feedback: Firewalls typically base their filtering on the TCP/IP characteristics at the network, transport, and application layers of the Open Systems Interconnection (OSI) reference model, as follows: - IP addresses: Represent specific computers on the network. - Protocol numbers: Identify the transport layer protocol being used by the packets. - Port numbers: Identify specific applications running on the computer.

Q: When using the Windows Firewall with Advanced Security console, you will see three distinct network locations that impact the behavior of the Windows Firewall. Which of the following is not one of these network locations used by the Windows Firewall?
- Default
- Public
- Domain
- Private
A: Default
Feedback: Windows Firewall maintains separate profiles for each of the three possible network locations: domain, private, and public. If you connect the computer to a different network, as in the case of a laptop computer that you bring to an Internet hot spot in a coffee shop, Windows Firewall loads a different configuration for that profile and a different set of rules.

Q: A Windows Firewall policy file has what file extension?
- .wfp
- .waf
- .wfw
- .wfs
A: .wfw
Feedback: A policy file is a file with a .wfw extension that contains all of the property settings in a Windows Firewall installation, as well as all its rules, including the preconfigured rules and the ones you have created or modified. To create a policy file, you select Export Policy from the Action menu in the Windows Firewall with Advanced Security console and specify a name and location for the file.

Q: When do data protection technologies such as the Windows 8.1 Encrypting File System (EFS) and BitLocker protect data?
- At all times
- Only when the data is stored on a disk
- Only when the data is transmitted on the network
- Only when the computer is turned off
A: Only when the data is stored on a disk
Feedback: Data protection technologies such as the Windows 8.1 Encrypting File System (EFS) and BitLocker protect data while it is stored on a drive. However, they do nothing to protect data while it is being transmitted over the network, because they both decrypt the data before sending it. IPsec, by contrast, protects data while it is in transit.

Q: A 2x2 MIMO device has how many total transceivers?
- Two
- Four
- One
- Eight
A: Four
Feedback: IEEE 802.11n equipment increases wireless networking speeds by using multiple transmitter and receiver antennae on each device, in a process called multiple-input multiple-output (MIMO). For example, a device using a 2x2 MIMO format has two transmitters and two receivers, operating at different frequencies.
