Network Practice Test Questions with Complete Solutions
2024/2025
A network engineer conducts a redundancy check and identifies that interference exists due to a poor- quality cable. What is this finding called?Logging Levels MIB CRC CRC error - Correct Answer CRC error A user is having trouble connecting to the company's WiFi network. They have verified that the password is correct and the network is indeed available. What could be a potential issue with the device not connecting?Captive portal TLS settings Encryption protocol mismatch AAA server - Correct Answer Encryption protocol mismatch A user is connected to a remote desktop using the protocol WebSockets. What technology solution is the user using?Site-to-site VPN Remote desktop connection Authentication and authorization considerations Clientless VPN - Correct Answer Clientless VPN A network technician is troubleshooting network issues between a workstation and a virtual server running a beta application. Network performance is lacking and there seems to be issues in between the source and destination. Which command will provide the technician with the best information regarding other nodes between the workstation and the remote host? 1 / 3
dig arp route pathping - Correct Answer pathping A network technician suspects a short in the network cable and wants to test it. Identify which of the following tools will provide this capability.Tone generator Spectrum analyzer Loopback adapter Multimeter - Correct Answer Multimeter What parameter can be used to calculate the optical link budget? (Select all that apply.) Splices Attenuation Connectors Transmitter power - Correct Answer Splices Attenuation Connectors An attacker exploited a vulnerability within the operating system of a computer inside a bank's network.Although the attacker posed no serious threat, the network administrator wants to start taking security more seriously. Recommend a best practice that can help mitigate operating system vulnerabilities in the network. (Select all that apply.) Implement patch management Enable only required services 2 / 3
Implement control plan policing Enable DHCP snooping - Correct Answer Implement patch management Enable only required services What describes what happens when traffic is recirculated and amplified by loops in the switching topology?Hardware failure Asymmetrical routing Broadcast storm Routing loop - Correct Answer Broadcast storm A technician recently installed a Voice over Internet Protocol (VoIP) phone at a user's desk. The workstation is not able to browse the Internet. The VoIP phone connects directly to the Local Area Network (LAN), and the workstation connects to the phone in a daisy-chain fashion. Other devices can connect successfully to the phone. At which layer of the Open Systems Interconnection (OSI) model would a network technician most likely continue troubleshooting?Network Session Application Physical - Correct Answer Network An attacker created a rogue access point (AP) with the same Service Set Identifier (SSID) as a legitimate one, and then used a Denial of Service (DoS) technique to overcome the legitimate AP. Users were forced to disconnect from the network and reassociate with the attacker's AP. What is the goal of the attacker when setting up this kind of evil twin attack? (Select all that apply.) To snoop on connections with web servers To deauthenticate client connections To create an encryption protocol mismatch To steal user network credentials - Correct Answer To snoop on connections with web servers
