100: Network Configuration Flashcards

How many MAC sublayers does IEEE 802.11 define?

Answer: 2. 0

The IEEE 802.11 standard for wireless local area networks defines two MAC (Media Access Control) sublayers. These are the Distributed Coordination Function (DCF) and the Point Coordination Function (PCF), which manage how devices access the shared wireless medium and handle data transmission efficiently.

Which is not a protected wireless network technology?

Answer: None of these

WEP (Wired Equivalent Privacy), TKIP (Temporal Key Integrity Protocol), and AES (Advanced Encryption Standard) are all technologies used to secure wireless networks. WEP is an older, less secure encryption protocol, while TKIP and AES are components of WPA/WPA2/WPA3, offering stronger protection. Therefore, none of the listed options are *not* protected wireless network technologies.

Which protocol accesses emails from any device?

Answer: IMAP

IMAP (Internet Message Access Protocol) allows users to access and manage emails directly on the mail server. This means emails are stored on the server, and changes made on one device (like reading, deleting, or moving an email) are synchronized across all devices accessing that mailbox, making it ideal for accessing emails from multiple locations.

The term "WiMAX" was coined by WiMAX Forum, which was established in?

Answer: Fri Jun 01 00:00:00 IST 2001

The WiMAX Forum, an industry organization dedicated to promoting and certifying the interoperability of broadband wireless access products based on the IEEE 802.16 standard, was officially established on June 1, 2001. This forum played a crucial role in standardizing and advancing WiMAX technology.

What combination of broad coverage, high reliability, and high performance does an LTE network offer best?

Answer: TRUE

LTE (Long-Term Evolution) networks are specifically designed to provide a superior mobile broadband experience. They offer significantly higher data speeds, lower latency, and improved spectral efficiency compared to previous generations, enabling broad coverage, high reliability, and excellent performance for various applications.

HSPA employs the HSDPA protocol, which supports a maximum theoretical data rate between?

Answer: 1.8 Mbps and 14.4 Mbps

HSPA (High-Speed Packet Access) is a 3G mobile telephony protocol that significantly enhances data transfer speeds. Specifically, HSDPA (High-Speed Downlink Packet Access), a key component of HSPA, theoretically supports downlink data rates ranging from 1.8 Mbps up to 14.4 Mbps, depending on the specific network implementation and channel conditions.

Ten-Gigabit Ethernet was developed by an IEEE committee and designated as a standard?

Answer: 802.3ae

The IEEE 802.3ae standard specifically defines Ten-Gigabit Ethernet, which is an extension of the Ethernet standard for operating at 10 gigabits per second. This standard was developed by the IEEE 802.3 working group to meet the increasing bandwidth demands in data centers and enterprise networks.
