20+ practice questions focused on Network Protocols — one of the most tested topics on the CompTIA A+ Core 1 220-1201 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Network Protocols PracticeA technician is configuring a network for a branch office that will use a router to connect to the main office over the internet. The connection must be encrypted and authenticated to ensure data privacy. Which protocol should the technician configure on the router?
Explanation: This scenario tests knowledge of IPsec, a suite of protocols used for secure VPN connections. IPsec provides encryption and authentication for IP packets, making it suitable for site-to-site VPNs over the internet.
During a network security audit, a technician finds that an employee is using a protocol that allows remote control of a computer with full graphical interface but without encryption. Which protocol should be replaced with a more secure alternative?
Explanation: This question tests knowledge of RDP, which provides remote desktop access. Unencrypted RDP is a security risk; it should be replaced with RDP over TLS or a VPN.
During a network upgrade, a technician installs a new wireless access point. Users on the new AP can access local resources but cannot browse the internet. The technician verifies that the AP has a valid IP address and can ping an external website by IP address. Which protocol is most likely misconfigured?
Explanation: This scenario tests DNS configuration. Being able to ping by IP address confirms IP connectivity, so the failure to browse is likely due to DNS not resolving domain names correctly.
A technician is setting up a new file server and needs to ensure that users can access shared folders using a friendly name like \\fileserver\share instead of an IP address. Which protocol must be configured correctly on the network?
Explanation: This question tests knowledge of DNS, which resolves hostnames to IP addresses. Without DNS, users would have to use IP addresses to access network resources.
A company deploys a new web server and wants to ensure that data transmitted between clients and the server is encrypted. The technician configures the server to use a certificate. Which protocol should be enabled on the server?
Explanation: This scenario tests knowledge of HTTPS, which is HTTP over TLS/SSL for encrypted communication. Using a certificate is a key part of setting up HTTPS.
