Microsoft Networking Essentials Exam Microsoft Networking Fundamentals v1 (98-366) 2 — Questions and Answers
Question 1: Which protocol is used to automatically assign IP addresses to hosts on a network?
- DNS
- DHCP (Correct answer)
- ARP
- ICMP
Correct answer: DHCP
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and other network configuration to hosts.
Question 2: What is the default subnet mask for a Class B IP address?
- 255.0.0.0
- 255.255.0.0 (Correct answer)
- 255.255.255.0
- 255.255.255.128
Correct answer: 255.255.0.0
Class B addresses use a default subnet mask of 255.255.0.0, providing 65,534 usable host addresses per network.
Question 3: Which OSI model layer is responsible for logical addressing and routing?
- Data Link
- Transport
- Network (Correct answer)
- Session
Correct answer: Network
The Network layer (Layer 3) handles logical addressing using IP addresses and determines the best path for packet routing.
Question 4: What type of cable uses light pulses to transmit data and is immune to electromagnetic interference?
- Coaxial
- Fiber optic (Correct answer)
- STP
- UTP
Correct answer: Fiber optic
Fiber optic cable transmits data as light pulses through glass or plastic strands, making it immune to EMI and capable of long-distance transmission.
Question 5: Which network topology connects all devices to a single central cable called a backbone?
- Star
- Ring
- Bus (Correct answer)
- Mesh
Correct answer: Bus
Bus topology connects all devices to a single shared cable (backbone), and a break in that cable can bring down the entire network segment.
Question 6: What does the acronym NAT stand for in networking?
- Network Address Translation (Correct answer)
- Network Access Technology
- Node Addressing Table
- Network Authentication Transfer
Correct answer: Network Address Translation
NAT (Network Address Translation) maps private IP addresses to a public IP address, allowing multiple devices to share one public IP.
Question 7: Which wireless standard operates exclusively in the 5 GHz band and offers speeds up to 54 Mbps?
- 802.11b
- 802.11g
- 802.11a (Correct answer)
- 802.11n
Correct answer: 802.11a
802.11a operates exclusively in the 5 GHz band with a maximum speed of 54 Mbps but has shorter range than 2.4 GHz standards.
