100

This protocol is used to automatically assign IP addresses to devices on a network.

What is DHCP (Dynamic Host Configuration Protocol)?

100

In this physical topology, all nodes connect to a central device such as a switch or hub.

What is a star topology?

100

The number of layers in the OSI reference model.

What is seven?

100

This type of attack attempts to overwhelm a network or server by flooding it with illegitimate traffic.

What is a Denial of Service (DoS) attack?

100

The most common frequency bands used by Wi-Fi networks.

What are 2.4 GHz and 5 GHz?

200

This protocol translates domain names to IP addresses.

What is DNS (Domain Name System)?

200

This topology connects each device to two other devices, forming a closed loop.

What is a ring topology?

200

This OSI layer is responsible for error detection and correction, and includes MAC addresses.

What is the Data Link Layer (Layer 2)?

200

This common security measure restricts network access based on MAC addresses.

What is MAC filtering?

200

This wireless security protocol replaced WEP and uses TKIP for encryption.

What is WPA (Wi-Fi Protected Access)?

300

This connection-oriented transport protocol provides reliable, ordered delivery of data.

What is TCP (Transmission Control Protocol)?

300

This topology type provides high redundancy by connecting each device to every other device in the network.

What is a mesh topology?

300

This OSI layer handles logical addressing and routing between networks.

What is the Network Layer (Layer 3)?

300

This security protocol provides encrypted communications over a computer network and is commonly used for secure web browsing.

What is SSL/TLS (Secure Sockets Layer/Transport Layer Security)?

300

This device increases the range of a wireless network by receiving and retransmitting the wireless signal.

What is a wireless repeater or range extender?

400

This protocol allows network administrators to manage and monitor network devices remotely.

What is SNMP (Simple Network Management Protocol)?

400

This logical topology divides a network into smaller, more manageable sections to improve performance and security.

What is network segmentation or subnetting?

400

The top three layers of the OSI model (5-7) are collectively known as these types of layers.

What are the host layers or upper layers?

400

This device or software inspects and filters traffic between networks based on predetermined security rules.

What is a firewall?

400

This wireless network mode allows devices to connect directly to each other without an access point.

What is ad-hoc mode?

500

This protocol suite replaced NetBEUI and IPX/SPX in most modern networks and consists of multiple protocols arranged in layers.

What is TCP/IP (Transmission Control Protocol/Internet Protocol)?

500

This network design uses a hierarchical approach with core, distribution, and access layers.

What is a three-tier architecture or hierarchical network or data center design?

500

HTTP, FTP, SMTP, and DNS all operate at this layer of the OSI model.

What is the Application Layer (Layer 7)?

500

This security method creates an encrypted connection over a less secure network, allowing for secure remote access to a private network.

What is a VPN (Virtual Private Network)?

500

This Wi-Fi standard, also known as 802.11ac, operates on the 5 GHz band and provides theoretical speeds up to 3.5 Gbps.

What is Wi-Fi 5?
