A spectrum analyzer is used to identify sources of interference and optimize wireless networks.

SDN decouples the control plane from the data plane, allowing for centralized management and control of the network.

Satellite internet connectivity is suitable for remote locations where traditional wired connections are not feasible, such as a remote mining site.

802.11ac introduced the use of 256-QAM modulation for higher data rates and improved performance, enhancing wireless efficiency and speed.

A physical network diagram provides a detailed map of a network’s physical layout, showing the location of devices and cabling.

A DHCP relay agent forwards DHCP requests from clients in different subnets to a central DHCP server.

The Application layer provides network services directly to end-user applications, facilitating communication between software applications and lower layers of the OSI model.

Hubs operate at the Physical layer (Layer 1) and are responsible for transmitting signals to all connected devices.

PoE (Power over Ethernet) provides power to network devices through Ethernet cables, simplifying installation and reducing the need for additional power outlets.

The Device Manager in Windows allows you to check and reconfigure the network card settings.

Malware is malicious software designed to damage, disrupt, or gain unauthorized access to a computer system.

A DHCP scope defines the range of IP addresses available for dynamic assignment to devices on the network.

A punch-down tool is used to terminate Ethernet cables into a patch panel by securing the cables properly.

Routing loops involve a loop in the network routing paths, causing packets to circulate indefinitely.

Incorrect passphrase is the common issue when a user is unable to connect to a wireless network due to entering the wrong security information.

A Storage Area Network (SAN) is a dedicated network for managing large amounts of data storage and providing high-speed access to data for servers.

A business continuity plan is essential for outlining procedures during prolonged disruptions, ensuring that critical business operations can continue.

A BYOD policy is important to define the rules and security measures for using personal devices for work purposes, ensuring data security and compliance.

BGP is considered a path vector protocol and is used primarily for inter-domain routing on the Internet, providing scalability and policy-based routing.

The subnet mask 255.255.255.224 (or /27) supports up to 30 usable IP addresses. It provides 32 addresses in total, with 2 addresses reserved for network and broadcast addresses.

Electrical sensors monitor the risk of electrical surges or outages in a data center, helping to protect sensitive equipment from damage.

A hypervisor is responsible for managing multiple virtual environments, allowing different operating systems to run on a single physical server.

Humidity sensors are critical for preventing moisture-related damage in data centers, ensuring optimal humidity levels to protect sensitive equipment.
