Q1. No matter where a device is used, what address will stay the same regardless of the network it is attached to?
Answer: Physical, or MAC, address
Explanation: The MAC address is a hardware identifier assigned to a network interface card (NIC) and remains constant across networks.
Q2. How many bits long is an IP address?
Answer: 32 bits
Explanation: An IPv4 address is 32 bits long, divided into four 8-bit sections (octets). IPv6 uses 128 bits.
Q3. QoS services are protocols that allow routers to make decisions about which IP datagram may be more important than others. Under which IP header field would QoS details be found?
Answer: Service Type field
Explanation: The Service Type field in the IP header contains Quality of Service (QoS) details, enabling routers to prioritize data packets.
Q4. Generally, what are Class E IP addresses used for?
Answer: Testing
Explanation: Class E IP addresses (240.0.0.0–255.255.255.255) are reserved for experimental and testing purposes and are not used in public networks.
Q5. Why do entries in a local Address Resolution Protocol (ARP) table expire after a short amount of time?
Answer: To account for network changes
Explanation: ARP entries expire to reflect changes in the network, ensuring accurate mapping of IP addresses to MAC addresses.
Q6. When describing blocks of IP addresses, what does CIDR do?
Answer: Uses subnet masks to demarcate networks
Explanation: Classless Inter-Domain Routing (CIDR) uses subnet masks to define variable-length subnetting, making IP address allocation more efficient.
Q7. A router is performing basic routing functions. What is the second step in the transmission of a packet?
Answer: The router examines the destination IP of this packet.
Explanation: After receiving a packet, the router examines the destination IP address to determine the appropriate next step.
Q8. Interior gateway protocols are used by routers in order to share information within a single…
Answer: autonomous system
Explanation: Interior Gateway Protocols (IGPs) operate within a single autonomous system (AS), enabling efficient routing within the same organization.
Q9. What protocol communicates data between routers representing the edges of autonomous systems?
Answer: Exterior gateway
Explanation: Exterior Gateway Protocols (EGPs), such as BGP, facilitate communication between routers at the boundaries of autonomous systems.
Q10. What does RFC stand for?
Answer: Request For Comments
Explanation: RFCs are documents published by the Internet Engineering Task Force (IETF) that define standards, protocols, and best practices for the internet.
