Microsoft Networking Essentials Exam Microsoft Networking Essentials: Final Course 4 — Questions and Answers
Question 1: Which command on a Windows system displays the current IP configuration including IPv4 address, subnet mask, and default gateway?
- ipconfig /all (Correct answer)
- netstat -r
- route print
- nslookup
Correct answer: ipconfig /all
ipconfig /all displays full TCP/IP configuration details including IP address, subnet mask, gateway, DNS servers, and MAC address.
Question 2: What is the maximum segment length for a standard 1000BASE-T (Gigabit Ethernet over copper) connection?
- 55 meters
- 100 meters (Correct answer)
- 150 meters
- 185 meters
Correct answer: 100 meters
1000BASE-T uses Cat 5e or higher UTP cabling with a maximum segment length of 100 meters.
Question 3: A technician runs tracert to a remote host and sees asterisks (*) at every hop. What is the most likely cause?
- The destination host is down
- ICMP traffic is being blocked by firewalls along the path (Correct answer)
- The default gateway is misconfigured
- DNS resolution has failed
Correct answer: ICMP traffic is being blocked by firewalls along the path
Asterisks in tracert output indicate that routers along the path are not responding to ICMP TTL-exceeded messages, usually because of firewall rules.
Question 4: Which protocol uses TCP port 22 and provides encrypted remote command-line access to network devices?
- Telnet
- SSH (Correct answer)
- RDP
- SFTP
Correct answer: SSH
SSH (Secure Shell) uses TCP port 22 to provide encrypted terminal sessions, replacing the insecure Telnet protocol.
Question 5: An IPv6 address of fe80::1 belongs to which address type?
- Global unicast
- Multicast
- Link-local (Correct answer)
- Loopback
Correct answer: Link-local
Addresses beginning with fe80::/10 are link-local addresses, automatically assigned and only valid on a single network segment.
Question 6: Which network topology provides the highest fault tolerance because every device is connected to every other device?
- Bus
- Ring
- Star
- Full mesh (Correct answer)
Correct answer: Full mesh
A full mesh topology connects every node directly to every other node, providing maximum redundancy and fault tolerance.
Question 7: What does the 'well-known' TCP port range include?
- 0–1023 (Correct answer)
- 1024–49151
- 49152–65535
- 0–4095
Correct answer: 0–1023
Well-known ports are numbered 0–1023 and are reserved by IANA for standard protocols like HTTP (80), FTP (21), and DNS (53).
