Microsoft Networking Essentials Exam Microsoft Networking Fundamentals v1 (98-366) 3 — Questions and Answers
Question 1: A network administrator needs to connect two switches in the same building. Which device would be MOST appropriate to use?
- Hub
- Router
- Bridge (Correct answer)
- Repeater
Correct answer: Bridge
A bridge connects two network segments at the Data Link layer, filtering traffic based on MAC addresses to reduce collisions.
Question 2: What is the valid host range for the network 192.168.10.64/26?
- 192.168.10.65 to 192.168.10.126 (Correct answer)
- 192.168.10.64 to 192.168.10.127
- 192.168.10.65 to 192.168.10.128
- 192.168.10.64 to 192.168.10.128
Correct answer: 192.168.10.65 to 192.168.10.126
A /26 mask gives 64 addresses per subnet; .64 is the network address and .127 is broadcast, so valid hosts are .65 through .126.
Question 3: Which protocol operates at the Transport layer and provides reliable, connection-oriented communication?
- UDP
- IP
- TCP (Correct answer)
- ICMP
Correct answer: TCP
TCP (Transmission Control Protocol) provides reliable, ordered, error-checked delivery of data through connection establishment via a three-way handshake.
Question 4: What is the purpose of a default gateway in a network configuration?
- To assign IP addresses to local hosts
- To resolve domain names to IP addresses
- To forward packets destined for remote networks (Correct answer)
- To filter incoming network traffic
Correct answer: To forward packets destined for remote networks
The default gateway is a router's IP address that local hosts use to forward packets destined for networks outside the local subnet.
Question 5: Which media access control method does Ethernet use to manage collisions on a shared medium?
- TDMA
- FDMA
- CSMA/CD (Correct answer)
- Token passing
Correct answer: CSMA/CD
Ethernet uses CSMA/CD (Carrier Sense Multiple Access with Collision Detection) to detect collisions and retransmit data after a random backoff period.
Question 6: Which IPv6 address type is equivalent to the IPv4 private address space and is only routable within a local network?
- Link-local
- Global unicast
- Unique local (Correct answer)
- Multicast
Correct answer: Unique local
Unique local addresses (fc00::/7) in IPv6 are the equivalent of IPv4 private addresses and are not routable on the public internet.
Question 7: A technician is setting up a small office and needs devices to communicate without any cabling. Which technology should be implemented?
- Fiber channel
- WLAN (Correct answer)
- VLAN
- WAN
Correct answer: WLAN
WLAN (Wireless Local Area Network) using Wi-Fi standards allows devices to communicate over radio frequencies without physical cabling.
