Which layer of the OSI model is responsible for logical addressing and routing packets between networks?
Answer: Network
The Network layer (Layer 3) handles logical addressing (IP) and determines the best path for routing packets across networks.
A technician needs to find the MAC address of a Windows PC. Which command should they use?
Answer: ipconfig /all
The 'ipconfig /all' command displays detailed network adapter information including the physical (MAC) address.
What is the default subnet mask for a Class B IP address?
Answer: 255.255.0.0
Class B addresses use a default subnet mask of 255.255.0.0, covering the range 128.0.0.0 to 191.255.255.255.
Which protocol automatically assigns IP addresses to devices on a network?
Answer: DHCP
DHCP (Dynamic Host Configuration Protocol) dynamically assigns IP addresses, subnet masks, gateways, and DNS servers to network clients.
What does the acronym 'LAN' stand for?
Answer: Local Area Network
LAN stands for Local Area Network, referring to a network that covers a small geographic area such as a building or campus.
At which OSI layer do switches primarily operate?
Answer: Layer 2 - Data Link
Standard switches operate at Layer 2 (Data Link) and forward frames based on MAC addresses in their CAM table.
Which IPv4 address range is reserved for loopback testing?
Answer: 127.0.0.0/8
The 127.0.0.0/8 range is reserved for loopback; pinging 127.0.0.1 tests the local TCP/IP stack without sending traffic to the network.
