WPA2-Personal, also known as WPA2-PSK (Pre-Shared Key), is the wireless security option that uses a pre-shared key to authenticate clients. This method is designed for home and small office networks and doesn’t require an authentication server. Instead, every user on the network uses the same key or passphrase to connect1.

•Exploring WPA-PSK and WiFi Security

=========================

•WPA2-Personal: This wireless security option uses a pre-shared key (PSK) for authentication. Each client that connects to the network must use this key to gain access. It is designed for home and small office networks where simplicity and ease of use are important.

•WPA2-Enterprise: Unlike WPA2-Personal, WPA2-Enterprise uses 802.1x authentication with an authentication server (such as RADIUS) and does not rely on a pre-shared key.

•802.1x: This is a network access control protocol for LANs, particularly wireless LANs. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.

•802.1q: This is a networking standard that supports VLAN tagging on Ethernet networks and is not related to wireless security.

Two home office computers are connected to a switch by Ethernet cables.

Network Type: LAN (Local Area Network)

Explanation: A LAN connects devices within a limited area such as a home, office, or building, using Ethernet cables or Wi-Fi.

Three government buildings in the same city connect to a cable company over coaxial cables.

Network Type: MAN (Metropolitan Area Network)

Explanation: A MAN connects networks across a city or campus, often using fiber optic or coaxial cables.

A cell phone connects to a Bluetooth headset.

Network Type: PAN (Personal Area Network)

Explanation: A PAN connects devices within a personal workspace, typically using wireless technologies like Bluetooth.

A financial institution connects its branches through a telecommunications service provider.

Network Type: WAN (Wide Area Network)

Explanation: A WAN connects multiple LANs over long distances, often using leased lines or satellite links provided by telecommunications companies.

LAN (Local Area Network): Used for connecting devices within a small geographical area such as a single building or home.

MAN (Metropolitan Area Network): Covers a larger geographical area than a LAN, typically a city or campus.

PAN (Personal Area Network): Connects devices within the range of an individual person, such as connecting a phone to a Bluetooth headset.

WAN (Wide Area Network): Spans large geographical areas, connecting multiple LANs across cities, countries, or continents.

When devices within a VLAN are unable to reach addresses outside their VLAN, it typically indicates that they do not have a configured path to external networks. The engineer should configure a default gateway for VLAN2. The default gateway is the IP address of the router’s interface that is connected to the VLAN, which will route traffic from the VLAN to other networks12.

=========================

•VLANs: Virtual Local Area Networks (VLANs) logically segment network traffic to improve security and performance. Devices within the same VLAN can communicate directly.

•Default Gateway: For devices in VLAN2 to communicate with devices outside their VLAN, they need a default gateway configured. The default gateway is typically a router or Layer 3 switch that routes traffic between different VLANs and subnets.

•Additional VLAN: Not needed in this scenario as the issue is related to routing traffic outside VLAN2, not creating another VLAN.

•Default Route: While a default route on the router may be necessary, the primary issue for devices within VLAN2 is to have a configured default gateway.

•Static Route: This is used on routers to manually specify routes to specific networks but does not address the need for a default gateway on the client devices.
