   A network administrator wants users to be able to authenticate to the corporate network using a port-based authentication framework when accessing both wired and wireless devices. Which of the following is the best security feature to accomplish this task?

   • A802.1X
   • BAccess control list
   • CPort security
   • DMAC filtering

   Show answer

   Answer: A

   Explanation

   A. 802.1X Explanation: 802.1X is a port-based network access control (PNAC) framework that provides authentication for devices trying to connect to the network, both wired and wireless. It uses an authentication server (typically RADIUS) to verify the identity of devices before granting them access, ensuring that only authorized users can connect to the network

   Which of the following is most closely associated with a dedicated link to a cloud environment and may not include encryption?

   • ADirect Connect
   • BInternet gateway
   • CCaptive portal
   • DVPN

   Show answer

   Answer: A

   Explanation

   A. Direct Connect Explanation: Direct Connect is a service provided by cloud providers (such as AWS Direct Connect) that establishes a dedicated, private link between a company’s on-premises network and the cloud environment. This connection is typically used for high-bandwidth, low-latency communication and may not include encryption by default, as the link itself is private and separate from the public internet.

   A systems administrator is investigating why users cannot reach a Linux web server with a browser but can ping the server IP. The server is online, the web server process is running, and the link to the switch is up. Which of the following commands should the administrator run on the server first?

   • Atraceroute
   • Bnetstat
   • Ctcpdump
   • Darp

   Show answer

   Answer: B

   Explanation

   The correct answer is: B. netstat Explanation: The netstat command is used to check the listening ports and active network connections on a system. Since the web server process is running and users can ping the server, the issue might be related to whether the web server is properly listening on the expected port (e.g., TCP port 80 for HTTP or TCP port 443 for HTTPS). Running netstat (or its modern replacement, ss) can quickly verify if: The web server is listening on the expected port. The service is bound to the correct IP address or network interface.

   Which of the following devices can operate in multiple layers of the OSI model?

   • AHub
   • BSwitch
   • CTransceiver
   • DModem

   Show answer

   Answer: B

   Explanation

   The correct answer is: B. Switch Explanation: A switch can operate at multiple layers of the OSI model, depending on its type: Layer 2 (Data Link Layer): Most switches are Layer 2 devices. They forward traffic based on MAC addresses and use a MAC address table to direct frames to the appropriate ports. Layer 3 (Network Layer): Layer 3 switches (often called multilayer switches) can perform routing functions, forwarding traffic based on IP addresses. These switches combine the functionality of traditional Layer 2 switches and routers, making them versatile in modern networks.

It forces users to accept the terms of use before granting full access to the internet or the network. This method is commonly used to ensure that users acknowledge and agree to the network's policies.
