Which connectivity device regenerates and retransmits signals to extend the physical reach of a network?
Repeater
Bridge
Switch
Router
A repeater works at the physical layer to regenerate weakened signals, allowing them to travel longer distances without degradation. It does not perform any filtering or routing functions. Repeaters simply amplify or reshape the incoming signal before retransmission. For more details, see Cisco.
Which device operates at the network layer (Layer 3) of the OSI model to direct packets between different IP networks?
Router
Hub
Switch
Bridge
Routers examine IP addresses in packet headers to determine the optimal path for forwarding data to different networks. They maintain routing tables and perform network address translation when needed. Routers can connect diverse network architectures and support various WAN technologies. Learn more at Cisco.
Which connectivity device uses MAC addresses to intelligently forward frames only to the destination port?
Switch
Hub
Bridge
Repeater
Switches operate at the data link layer and maintain a MAC address table to forward frames only to the appropriate port, reducing unnecessary traffic. This segmentation improves network efficiency and security compared to hubs. Managed switches can also support VLANs and QoS policies. For more information, visit Network World.
Which device broadcasts incoming electrical signals to all connected ports without filtering?
Hub
Switch
Router
Repeater
A hub is a simple physical-layer device that repeats incoming signals to every port, creating a single collision domain. It does not filter or direct traffic based on addresses. Because of this, hubs are largely obsolete and have been replaced by switches. Read more at Techopedia.
Which device modulates and demodulates digital signals for transmission over analog telephone lines?
Modem
Switch
Bridge
Gateway
A modem (modulator–demodulator) converts digital signals from a computer into analog signals for telephone lines and vice versa. It enables digital devices to communicate over analog infrastructures. While traditional dial-up modems are slower, DSL and cable modems are more common in modern networks. See Cisco White Paper.
Which device connects networks using different protocols by translating between them?
Gateway
Router
Switch
Repeater
A gateway sits at a network boundary and translates data between different network protocols or architectures, such as IP to proprietary formats. It operates at multiple OSI layers depending on the translation complexity. Gateways are often used to integrate legacy systems with modern networks. More details at TechTarget.
Which device provides wireless client connectivity by bridging wired and wireless networks?
Access Point
Switch
Router
Hub
An access point (AP) connects wireless devices to a wired network, managing Wi-Fi connections and security. It handles tasks like SSID broadcasting and encryption, often supporting multiple bands and standards. APs can be standalone or controller-managed in enterprise environments. Learn more from Cisco.
Which device divides a network into separate collision domains but uses frame forwarding at the data link layer?
Bridge
Switch
Hub
Router
A bridge connects two LAN segments, using MAC addresses to forward or filter frames while splitting collision domains. Unlike a switch, a bridge often has fewer ports and simpler management. Bridges operate at OSI Layer 2 and can be used to reduce traffic and collisions. For additional reading see GeeksforGeeks.
Which physical-layer device converts signals between different media types, such as copper to fiber optic?
Media Converter
Repeater
Router
Hub
Media converters adapt between different physical media, such as twisted-pair to fiber, allowing diverse segments to connect seamlessly. They simply translate signal formats without higher-layer processing. Converters support various speeds and protocols based on the media types. More at Fiber Optic Guide.
Which device uses wavelength division multiplexing to combine multiple optical signals onto a single fiber?
Optical Multiplexer
Media Converter
Switch
Gateway
An optical multiplexer (WDM) combines multiple wavelengths into a single fiber, increasing bandwidth without additional fibers. It operates at the physical layer, supporting dense or coarse wavelength division multiplexing. This technology is critical in long-haul and metro fiber networks.

Which device terminates a digital WAN circuit and translates it into a format usable by LAN equipment?
CSU/DSU
Modem
Router
Switch
A CSU/DSU terminates digital circuits like T1/E1 and adapts them to LAN equipment, providing proper signal framing and timing. It ensures the data stream complies with the service provider's specifications. Routers often include integrated CSU/DSU modules for convenience. More information at Cisco.
Which device distributes client requests across multiple servers to improve performance and reliability?
Load Balancer
Router
Switch
Firewall
A load balancer sits between clients and servers, distributing traffic based on algorithms (round-robin, least connections, etc.) to optimize resource use and ensure high availability. It can operate at Layer 4 or Layer 7, performing health checks and SSL offloading. Load balancers are essential in scalable web architectures. See F5 Networks.
Which advanced connectivity device uses software-defined networking to manage and optimize traffic across multiple WAN links based on application policies?
SD-WAN Edge Device
Traditional Router
Bridge
Optical Multiplexer
An SD-WAN edge device uses software-defined networking principles to dynamically route traffic across multiple WAN links based on real-time metrics and predefined policies. It delivers improved performance, centralized control, and cost efficiencies compared to traditional routers. SD-WAN solutions support application-aware routing, encryption, and simplified management. For more information visit VMware.

Cheat Sheet
OSI Layers and Device Roles -
When tackling the connectivity devices quiz, recall that hubs function at Layer 1 (Physical), switches at Layer 2 (Data Link), and routers at Layer 3 (Network), as defined by IEEE and OSI Reference Model documentation. A handy mnemonic, "Please Do Not Throw Sausage Pizza Away," helps remember the seven layers from Physical to Application. Linking device roles to layers streamlines learning for any network hardware quiz or certification prep.
MAC vs IP Addressing & Forwarding -
Switches use MAC addresses (Layer 2) to forward frames based on entries learned in their CAM table, per IEEE 802.3 specifications, while routers use IP addresses (Layer 3) and routing tables governed by IETF's RFC 791. For example, a switch checks 00-14-22-01-23-45 in its MAC table, whereas a router evaluates 192.168.1.1 against its routing table. Understanding this difference is key for answering connectivity devices questions accurately.
VLAN Tagging and Trunking Essentials -
Learn IEEE 802.1Q VLAN tagging so you can segment traffic on managed switches and use trunk ports to carry multiple VLANs - think "Q for Quick Tunnel" as a mnemonic for the 802.1Q tag. An 802.1Q tag adds a 4-byte header with a VLAN ID (1 - 4094) to Ethernet frames, a concept covered in Cisco's documentation. Mastery of VLANs is invaluable for networking devices trivia and practical enterprise setups.
Routing Protocols and Administrative Distance -
Get familiar with dynamic routing protocols like OSPF (RFC 2328), RIP (max 15 hops), and BGP, noting that each has a default administrative distance (e.g., OSPF 110, EIGRP 90) used to choose the best route. A simple formula - "Lower AD wins, then lower metric" - helps decide which route a router installs. This concept often appears in network hardware quiz sections on routing fundamentals.
Wireless Standards and Access Point Functions -
Dive into IEEE 802.11 standards - b/g/n/ac/ax - to understand throughput and range differences across 2.4 GHz vs 5 GHz bands, with MIMO technologies boosting performance. For instance, 802.11ac uses beamforming and MU-MIMO to achieve gigabit speeds, as documented by the Wi-Fi Alliance. Knowing AP features is crucial for acing a network devices test or any connectivity devices quiz challenge.
