Which OSI layer is related to the function of the IP protocol suite? - Network Which OSI layer is responsible for organizing how bits are passed over the physical layer between devices within the same collision domain? - Data link Which OSI 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 Which protocol suite performs functions of OSI layer 4? - TCP Which type of Ethernet cable can maintain 10Gbps transmission speeds through the course of its maximum 100-meter length? - CAT 6a Which device is used to organize network cables as they run between switches and other network devices? - Patch panel Which networking standard uses UTP cable and CSMA/CD to manage connected devices' access to the wire? - Ethernet What facilitates network functions at the data link and physical layers by use of a unique MAC address? - NIC Which network device is used to connect two or more network segments by performing OSI layer 3 functions like packet-forwarding? - Router Which network device can be used as shared storage for all member nodes of a LAN? - File server Which device is responsible for implementing network address translation (NAT)? - Router Which command produces the following output? Non-authoritative answer: Name: Address: 172.217.11.132 - nslookup Which network protocol allows a user to authenticate to a remote server, navigate the server's file structure, and upload and download files? - ftp Which network diagnostic tool displays the path packets take between two endpoints? - traceroute Which network type is used to wire multiple PCs to a home router? - LAN 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 What type of medium is commonly used within a 1000 Mbps Ethernet network? - CAT5e Which network topology is shown in the following diagram? - Full mesh 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 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 Which OSI layer ensures error-free packets? - Transport Which topology uses a switch or hub to connect to all devices in the same network? - Star Which cloud model provides an exclusive cloud computing service environment that is shared between two or more organizations? - Community Which service offering provides the tools and environment for application development and testing? - PaaS Which type of software is used to provide virtualization? - Hypervisor 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 An attacker attempts to misdirect traffic 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 poisoning Which exploit actually breaches the physical medium or uses devices to monitor signals from outside the physical medium itself? - Wiretapping
