Free MD 100: Network Configuration Questions and Answers — Questions and Answers
Question 1: How many MAC sublayers does IEEE 802.11 define?
- 1. 0
- 3. 0
- 4. 0
- 2. 0 (Correct answer)
Correct 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.
Question 2: Which is not a protected wireless network technology?
- None of these (Correct answer)
- WEP
- TKIP
- AES
Correct 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.
Question 3: Which protocol accesses emails from any device?
- IMAP (Correct answer)
- POP
- PGP
- TCP
Correct 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.
Question 4: The term "WiMAX" was coined by WiMAX Forum, which was established in?
- Sat Jun 01 00:00:00 IST 2002
- Fri Jun 01 00:00:00 IST 2001 (Correct answer)
- Sun Jul 01 00:00:00 IST 2001
- Wed Aug 01 00:00:00 IST 2001
Correct 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.
Question 5: What combination of broad coverage, high reliability, and high performance does an LTE network offer best?
- FALSE
- TRUE (Correct answer)
Correct 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.
Question 6: HSPA employs the HSDPA protocol, which supports a maximum theoretical data rate between?
- 1.4 Mbps and 12.2 Mbps
- None of the above
- 1.8 Mbps and 14.4 Mbps (Correct answer)
- 1.2 Mbps and 16.4 Mbps
Correct 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.
Question 7: Ten-Gigabit Ethernet was developed by an IEEE committee and designated as a standard?
- 802.11
- 802.3ae (Correct answer)
- 802.3
- 802.5
Correct 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.
