C172 - Network & Security Foundations - PA 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 00:0902:01 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? Cat6a Which Internet access technology uses ordinary telephone wires for data transmission? DSL Which device is used to organize network cables as they run between switches and other network devices? Patch panel 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 is used to convert between digital information from a LAN and analog signals for transmission over a standard telephone wire? Modem Which device could be used to send commands to the mainframe for remote execution in early mainframe installations? Dumb terminals 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 command should be used to manually enter the default gateway for a computer? route 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 service provides hardware, operating systems, and web servers but not end-user applications? PaaS Which cloud model provides an exclusive cloud computing service environment that is shared between two or more organizations? Community 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 Which type of attack can overwhelm a web server by inserting more data into a web form than the system was configured to hold? Buffer overflow Which type of attack sends an email claiming to be from a reputable business in order to entice the recipient to provide sensitive information? Phishing A user on a network is planning to launch an exploit against a coworker in a neighboring department. The user needs to identify the IP address of a coworker in the desired department. Which tool or utility will allow the user to watch network traffic in real time to identify a target? Sniffer Which group of attackers is typically used for penetration testing? Red team Which type of attack exploits an unpatched software vulnerability? Zero-day A company has the policy that all new user passwords are P@ssw0rd but does not require new users to change their password. An employee randomly tries a coworker’s account with the new user password to see if they can log in as the coworker. Which type of vulnerability does this create? Default password An employee that does not want to miss emails from important clients sets up her cellular smartphone to allow her to check email. Unfortunately, she does not install antivirus software on the cellular phone. What type of vulnerability is represented? BYOD/mobile [...] [...] What is required to establish a secure connection to a remote ne
