1. Which OSI(Open Systems Interconnection model) layer is related to the function of the IP protocol suite?: Network 2. Which OSI(Open Systems Interconnection model) layer is responsible for organizin... g how bits are passed over the physical layer between devices within the same collision domain?: Data link 3. Which OSI(Open Systems Interconnection model) layer would define the scope of a protocol that makes sure packets of data are received correctly and resends them if they are not?: Transport 4. Which protocol suite performs functions of OSI(Open Systems Intercon- nection model) layer 4?: TCP(Transmission Control Protocol) 5. Which type of Ethernet cable can maintain 10Gbps transmission speeds through the course of its maximum 100-meter length?: CAT 6a 6. Which Internet access technology uses ordinary telephone wires for data transmission?: DSL(Digital Subscriber Line) 7. Which device is used to organize network cables as they run between switches and other network devices?: Patch panel 8. Which network device is used to connect two or more network segments by performing OSI layer 3 functions like packet-forwarding?: Router 9. Which network device is used to convert between digital information from a LAN and analog signals for transmission over a standard telephone wire?: Modem 10. Which device could be used to send commands to the mainframe for remote execution in early mainframe installations?: Dumb terminals 11. Which device is responsible for implementing network address transla- tion (NAT)?: Router 12. Which command produces the following output? Non-authoritative answer: Name: Address: 172.217.11.132: nslookup 13. Which command should be used to manually enter the default gateway for a computer?: route 14. Which network diagnostic tool displays the path packets take between two endpoints?: raceroute 15. Which network type is used to wire multiple PCs to a home router?: - LAN(Local Area Network) 16. An office's infrastructure connects network devices and printers through a central access point without the use of cabling. Which network type does this office use?: WLAN(Wireless Local Area Network) 17. What type of medium is commonly used within a 1000 Mbps Ethernet network?: CAT5e 18. Which network topology is shown in the following diagram?: Full mesh 19. Which networking standard uses UTP(Unshielded Twisted Pair) cable and CSMA/CD(Carrier-sense multiple access with collision detection) to manage connected devices' access to the wire?: Ethernet 20. Which network topology is being implemented when each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node?: Ring 21. In which physical LAN topology are nodes connected to each other with a backbone cable that loops around and ends at the same point it started?: Ring 22. Which OSI(Open Systems Interconnection) layer ensures error-free pack- ets?: Transport 23. Which topology uses a switch or hub to connect to all devices in the same network?: Star 24. Which cloud service provides hardware, operating systems, and web servers but not end-user applications?: PaaS (Platform-as-a-service) 25. Which cloud model provides an exclusive cloud computing service envi- ronment that is shared between two or more organizations?: Community 26. Which type of software is used to provide virtualization?: Hypervisor 27. A user that does not want to be identified while communicating on a network uses an application to alter the computer's identity. Which type of exploit is being perpetrated?: Spoofing 28. An attacker attempts to misdirect traf c on a network back to the attacker by corrupting the network computer's cache of IP address to MAC address mappings that are cached. Which exploit is the attacker perpetrating?: ARP(Address Resolution Protocol) poisoning [Show More]
