In a ring topology, each node has a maximum of two connections.\u00a0<\/span><br \/>\n<b>Option B is incorrect.<\/b><span style=\"font-weight: 400;\"> In a star topology, each node is connected with a central point, which is a hub or switch. Therefore, each node has only one connection.<\/span><br \/>\n<b>Option C is incorrect.<\/b><span style=\"font-weight: 400;\"> Each node is connected to a running cable in a bus topology, which means that each node has only one connection.<\/span><br \/>\n<b>Option D is correct.<\/b><span style=\"font-weight: 400;\"> If the DHCP server is unavailable or unable to lease IP addresses to a client, the client uses the APIPA IP address by default.\u00a0<\/span><\/p>\n<p><b>Reference:<\/b><span style=\"font-weight: 400;\"> To know more about the mesh topology, please refer to the doc below:\u00a0<\/span><a href=\"https:\/\/www.bbc.co.uk\/bitesize\/guides\/zr3yb82\/revision\/2#:~:text=In%20a%20mesh%20topology%20there,message%20towards%20its%20final%20destination\" target=\"_blank\" rel=\"noopener\">https:\/\/www.bbc.co.uk\/bitesize\/guides\/zr3yb82\/revision\/2#:~:text=In%20a%20mesh%20topology%20there,message%20towards%20its%20final%20destination<\/a><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Domain_Networking_Fundamentals-2\"><\/span>Domain : Networking Fundamentals<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<h4><em>Q2 : On which layer of the OSI model does the TCP protocol work?<\/em><\/h4>\n<p><strong>A.<\/strong> Application<br \/>\n<strong>B.<\/strong> Presentation<br \/>\n<strong>C.<\/strong> Transport<br \/>\n<strong>D.<\/strong> Physical<\/p>\n<p><strong>Correct Answer: C <\/strong><\/p>\n<p><strong>Explanation:<\/strong><\/p>\n<p>The Transport layer is responsible for end-to-end communication.

After the connection is established, the user can access the network services based on the permissions granted. In this scenario, after you connect to the remote network, you can use SSH to connect with the Linux server.<br \/>\n<strong>Option B is incorrect<\/strong> as RDP is mainly used in the Windows environment. Also, the network does not allow incoming remote connections.<br \/>\n<strong>Option C is incorrect<\/strong> as the SSH connection cannot be used directly with the Linux server as the network does not allow incoming remote connections.<br \/>\n<strong>Option D is incorrect<\/strong> as SNMP is mainly used for device monitoring on a network.<\/p>\n<p><strong>Reference:<\/strong> To know more about Virtual Network Computing (VNC), please refer to the doc below:<a href=\"https:\/\/www.cisco.com\/c\/en_in\/products\/security\/vpn-endpoint-security-clients\/what-is-vpn.html\" target=\"_blank\" rel=\"noopener\">https:\/\/www.cisco.com\/c\/en_in\/products\/security\/vpn-endpoint-security-clients\/what-is-vpn.html<\/a><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Domain_Network_Security-6\"><\/span>Domain : Network Security<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<h4><em>Q24 : You manage a Windows network that has locked down clients.

You need to use a client. In the split-tunnel, the client is connected to the VPN server and can use the Internet as well.<br \/>\n<strong>Option B is incorrect<\/strong> as a full tunnel VPN connects to the VPN server, and then the client\u2019s traffic is routed through the VPN connection.<br \/>\n<strong>Option C is correct<\/strong> as a client-less VPN does not require a VPN client to be installed. The users can use an HTTPS-enabled Web browser to connect to the VPN server.<br \/>\n<strong>Option D is incorrect<\/strong> as RDP Gateway does not use VPN.
