Soho Networks Flashcards
What does SOHO stand for?
Small Office/Home Office.
What is the purpose of a SOHO router?
To provide internet access and manage network devices.
What is the default IP range for most SOHO routers?
192.168.x.x or 10.x.x.x.
What is the difference between a modem and a router?
A modem connects to the ISP, while a router connects devices within the network.
What is NAT, and why is it important for SOHO networks?
Network Address Translation allows multiple devices to share a single public IP address.
What type of cable is typically used for wired SOHO networks?
Ethernet cable (Cat5e or Cat6).
What is the maximum length for an Ethernet cable?
100 meters (328 feet).
What is the purpose of a switch in a wired network?
To connect multiple devices within the same network.
What is a common tool for testing Ethernet cable connectivity?
Cable tester or continuity tester.
What is the purpose of a patch panel?
To organize and manage Ethernet cable connections in a central location.
What does SSID stand for?
Service Set Identifier, which is the name of a Wi-Fi network.
What is the purpose of a wireless access point (WAP)?
To provide Wi-Fi connectivity to devices in the network.
What are the common Wi-Fi standards used in SOHO networks?
802.11n, 802.11ac, and 802.11ax.
What is the typical frequency range for Wi-Fi networks?
2.4 GHz and 5 GHz.
What is the difference between 2.4 GHz and 5 GHz Wi-Fi?
2.4 GHz offers longer range; 5 GHz offers higher speeds and less interference.
What is the purpose of WPA3 in wireless networks?
To provide enhanced security for Wi-Fi connections.
What is the purpose of a wireless channel?
To separate frequencies to reduce interference between networks.
What is a common method to secure a SOHO wireless network?
Enable WPA2/WPA3 encryption and set a strong password.
What is the purpose of a DHCP server in a SOHO network?
To assign IP addresses dynamically to connected devices.
What is the difference between static and dynamic IP addresses?
Static IPs are manually assigned; dynamic IPs are assigned by DHCP.
What is port forwarding?
A technique to allow external devices to access services within a private network.
What is QoS, and why is it important for SOHO networks?
Quality of Service prioritizes network traffic for certain devices or applications.
What is the purpose of a guest network?
To provide internet access for guests without allowing access to the main network.
What is the first step when troubleshooting a network issue in a SOHO environment?
Verify physical connections and check for power to devices.
What should you check if a wireless network is not visible?
Ensure the SSID is broadcast and the device is within range.
What is a common issue if a device cannot connect to Wi-Fi?
Incorrect password or incompatible Wi-Fi standard.
What is a common reason for slow network speeds?
Interference, bandwidth limitations, or outdated hardware.
What is the purpose of a firmware update for a router?
To fix bugs, improve performance, and enhance security.
What is the primary difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses; IPv6 uses 128-bit addresses.
How many addresses are available in IPv4?
Approximately 4.3 billion.
How many addresses are available in IPv6?
Approximately 340 undecillion.
What is an example of an IPv4 address?
192.168.1.1.
What is an example of an IPv6 address?
2001:0db8:85a3:0000:0000:8a2e:0370:7334.
What is a private IPv4 address range for Class A?
10.0.0.0 to 10.255.255.255.
What is a private IPv4 address range for Class B?
172.16.0.0 to 172.31.255.255.
What is a private IPv4 address range for Class C?
192.168.0.0 to 192.168.255.255.
What is a public IP address?
An IP address assigned by an ISP, accessible over the internet.
What is a private IP address?
An IP address used within a local network and not accessible directly over the internet.
What does APIPA stand for?
Automatic Private IP Addressing.
What is the IP range for APIPA?
169.254.0.1 to 169.254.255.254.
When is an APIPA address assigned?
When a device cannot obtain an IP address from a DHCP server.
What is a common issue if a device has an APIPA address?
The device cannot connect to other network devices or the internet.
What is a static IP address?
An IP address manually assigned to a device.
What is a dynamic IP address?
An IP address automatically assigned by a DHCP server.
What is a common use case for static IP addresses?
Servers, printers, and devices that require a fixed address.
What is a benefit of using dynamic IP addresses?
Simplifies network configuration and management.
What is a subnet mask used for?
To determine the network and host portions of an IP address.
What is CIDR notation?
Classless Inter-Domain Routing, e.g., /24 represents a subnet mask of 255.255.255.0.
What is the subnet mask for a /16 network?
255.255.0.0.
What is the purpose of subnetting?
To divide a network into smaller, more manageable segments.
What is the purpose of link-local IPv6 addresses?
To communicate within the same network segment; begins with FE80::.
What is the purpose of global unicast IPv6 addresses?
To communicate over the internet; starts with 2000::/3.
What is the purpose of multicast IPv6 addresses?
To send data to multiple destinations simultaneously; starts with FF00::/8.
What is an IPv6 unique local address (ULA)?
Private IPv6 address range used within a local network; starts with FC00::/7.
