• A.Ports identified with number 7
• B.Ports identified with number 6
• C.Ports identified with numbers 3 and 4
• D.Port identified with number 2

Move each network type from the list on the left to the correct example on the right.

Correct Answer:

Explanation:
* 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.

Which command will display the following output?

• A.show cdp neighbor
• B.show inventory
• C.show mac-address-table
• D.show ip interface

You plan to use a network firewall to protect computers at a small office.
For each statement about firewalls, select True or False.
Note: You will receive partial credit for each correct selection.

Correct Answer:

Explanation:
* A firewall can direct all web traffic to a specific IP address.
* True: Firewalls can be configured to perform Network Address Translation (NAT) and port forwarding, which can direct all web traffic (typically on port 80 and 443) to a specific internal IP address.
* A firewall can block traffic to specific ports on internal computers.
* True: Firewalls can be configured with access control lists (ACLs) or rules to block traffic to specific ports on internal computers, enhancing security by restricting unwanted or harmful traffic.
* A firewall can prevent specific apps from running on a computer.
* False: Firewalls typically control traffic flow and do not prevent specific applications from running on a computer. Application control is usually managed by endpoint security software or application control systems.
* Directing Web Traffic: Firewalls can manage traffic redirection using NAT and port forwarding rules to route web traffic to designated servers or devices within the network.
* Blocking Specific Ports: Firewalls can enforce security policies by blocking or allowing traffic based on port numbers, ensuring that only permitted traffic reaches internal systems.
* Application Control: While firewalls manage network traffic, preventing applications from running typically requires software specifically designed for endpoint protection and application management.
