Cisco CCST-Networking Dumps Questions Answers

• Two home office computers are connected to a switch by Ethernet cables.
• Three government buildings in the same city connect to a cable company over coaxial cables.
• A cell phone connects to a Bluetooth headset.
• A financial institution connects its branches through a telecommunications service provider.

• 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.

• The two interfaces are administratively shut down:
• The two interfaces have default IP addresses assigned:
• The two interfaces can communicate over Layer 2:

• Interface Status: The absence of the "shutdown" command means the interfaces are not administratively shut down.
• IP Address Assignment: There is no evidence in the output that IP addresses have been assigned to the interfaces, which would typically be shown as "ip address" entries.
• Layer 2 Communication: Switch interfaces in their default state operate at Layer 2, enabling them to forward Ethernet frames and participate in Layer 2 communication.

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.

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

•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.
