WIPS (Wireless Intrusion Prevention System) is specifically designed to stop attacks before they occur by constantly monitoring the wireless network for unauthorized access and suspicious activity. It uses advanced algorithms to detect and prevent attacks, such as rogue access points, MAC spoofing, and denial-of-service attacks. WIPS can also take automated actions to block or quarantine suspicious devices, providing an added layer of protection for the WLAN.

Question 8

Monitoring tools for wired networks always provide the full array of features necessary for monitoring WLANs.

Accepted Answer

Monitoring tools designed for wired networks may not have the necessary features to monitor wireless networks accurately, such as capturing and decoding wireless packets, analyzing WLAN traffic, and detecting rogue access points. Specialized WLAN monitoring tools are required to obtain meaningful data from wireless networks.

Question 9

____ allows computers and network equipment to gather data about network performance.
A) FTP
B) SNMP
C) SFTP
D) L2TP

Accepted Answer

SNMP (Simple Network Management Protocol) is a protocol that allows devices on a network to collect and share information about network performance, such as bandwidth usage, error rates and traffic congestion. FTP (File Transfer Protocol) and SFTP (Secure File Transfer Protocol) are used for transferring files, while L2TP (Layer 2 Tunneling Protocol) is used to create VPN (Virtual Private Network) tunnels.

Question 10

All networks require effective operational support to ensure that everything functions as intended.

Accepted Answer

Operational support is essential for ensuring that all network components work together properly, including hardware, software, and security measures. Without effective support, networks may experience downtime, security breaches, or other operational issues that can compromise productivity and reliability. Therefore, it is important for organizations to invest in the necessary resources to establish and maintain strong operational support for their networks.

Question 11

A ____ constantly monitors the radio frequency for attacks.
A) WIDS
B) SNMP
C) WLAN management system
D) SFTP system

Accepted Answer

A WIDS (Wireless Intrusion Detection System) is a security tool that monitors the radio frequency for attacks, and alerts administrators if any unauthorized access attempts or attacks are detected. SNMP (Simple Network Management Protocol) is a protocol used for network management, not specifically for wireless security. A WLAN (Wireless Local Area Network) management system is used to manage and monitor wireless networks, but it does not specifically monitor radio frequency for attacks. SFTP (Secure File Transfer Protocol) is used for secure file transfers, not wireless security.

Question 12

A secure WLAN should use WEP for its encryption, although WPA may be required in older legacy equipment.

Accepted Answer

WEP is not considered secure and has been deprecated for use in favor of WPA2. WPA should also not be used as it has known vulnerabilities. Therefore, a secure WLAN should use WPA2 or newer encryption standards.

Question 13

____ allows users to freely roam both indoors and outdoors for kilometers while remaining connected.
A) Fixed WiMAX
B) 3G
C) Mobile WiMAX
D) DSL WiMAX

Accepted Answer

Mobile WiMAX is specifically designed to provide users with high-speed broadband coverage while they move from place to place. It enables users to freely roam both indoors and outdoors for kilometers while remaining connected. Fixed WiMAX, on the other hand, provides coverage for a fixed location, and 3G and DSL WiMAX have limitations on the distance users can travel while maintaining a connection.

Question 14

Most people are taught using a(n) ____ approach, which comes from a Greek word meaning to lead a child.
A) pedagogical
B) neurological
C) visual
D) kinesthetic

Accepted Answer

The Greek word "paidagogos" means "to lead a child," and from this root comes the English word "pedagogue." Pedagogy is the method of teaching, and a pedagogical approach is one that is focused on helping students learn in the most effective way possible. This includes understanding their learning styles, providing feedback, and creating a supportive, engaging learning environment. The other options - neurological, visual, and kinesthetic - all relate to specific types of learning or aspects of the brain, but do not directly address the method of teaching or an overall approach to education.

Question 15

A) RF channel
B) coverage area
C) WLAN baseline
D) AP area

Accepted Answer

A WLAN baseline provides a record of the current state of the WLAN, including performance metrics, configurations, and equipment. This reference point enables a change request form process to compare the current state to the proposed changes and evaluate their impact on the WLAN. RF channel, coverage area, and AP area are all technical aspects of WLAN design and deployment, but do not specifically relate to the evaluation of proposed changes.

Question 18

At the heart of any secure WLAN is ____.
A) traffic filtering
B) protocol monitoring
C) education and training
D) strong encryption

Accepted Answer

Strong encryption is essential for securing WLANs. Encryption helps to safeguard data transmission over the wireless network by scrambling data so that it cannot be easily intercepted and read by unauthorized parties. Traffic filtering and protocol monitoring also help to enhance wireless security, but they are not the most critical. Education and training are essential to ensure that users follow best practices and avoid risky behaviors such as connecting to insecure networks or sharing passwords, but they do not provide the same level of protection as encryption.

Question 19

IEEE ____ allows a wireless client to determine the quality of service (QoS) and security being used at a different AP before making the transition.
A) 802.11a
B) 802.11g
C) 802.11i
