Network Security and Configuration Quiz

A software tool used to identify all devices connected to a network.

The standard 802.11 frequency range with the most available channels to minimize interference in a high-density wireless network.

A security feature on network switches that restricts access to specific ports by limiting the number of MAC addresses allowed to connect.

A database that stores information about known vulnerabilities, helping security professionals track and manage risks.

A network protocol that enables communication between a network management system and network devices.

A process of limiting access to a network based on geographical location.

A security feature on network switches that ensures only legitimate DHCP servers can provide IP addresses to clients.

The ability to configure a network switch to block unauthorized connections, typically used in publicly accessible areas.

The Time To Live (TTL) value in a DNS record determines how long a DNS resolver should cache the record before it needs to be refreshed from the authoritative DNS server.

An MX record (Mail Exchanger record) is a type of DNS record that specifies the mail server responsible for handling email for a particular domain.

A TXT record (Text record) is a type of DNS record that allows you to store arbitrary text information associated with a domain.

A SOA record (Start of Authority record) is a type of DNS record that provides information about the authoritative DNS server for a zone.

Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) is a media access control protocol used in wireless networks. It allows multiple devices to share the same wireless channel without causing collisions by using carrier sensing and backoff mechanisms.

Asset tags are unique identifiers attached to physical assets, such as computers, servers, and network devices. They help track the location, ownership, and maintenance history of the assets.

A configuration document used to enforce network infrastructure modifications and track changes.

East-West traffic within a data center occurs primarily between servers, virtual machines, or services located on the same physical network. Think of it as communication between devices within the same building or campus.

A network switch can be configured to log events at different verbosity levels. Debugging logs typically capture detailed information that can strain device resources.

Deploying multiple wireless access points (WAPs) with the same network name (SSID) is a common approach to create a seamless wireless network. It lets devices automatically connect without manually selecting an access point.

The process that ensures software updates are applied in a controlled manner and keeps track of changes made to the network.

This type of network traffic travels between different locations or segments of a network, such as between data centers or between buildings.

A metric that measures the amount of data being processed by a network device, indicating its capacity and efficiency.

When a network device experiences intermittent problems, they may be caused by resource exhaustion. This often happens when the device is trying to process excessive data or perform many operations simultaneously.

A type of DNS record that provides an alias for a hostname, mapping it to another hostname. It can be used to redirect clients to a different website or server when a company is acquired.

A feature that prioritizes specific network traffic, ensuring high-quality service for applications like video conferencing.

A technique used to replicate network traffic to a separate device for analysis and troubleshooting.

A firewall rule that blocks any traffic not explicitly allowed by preceding rules. It's typically the last rule in a firewall configuration.

A technique for shaping network traffic to prioritize specific applications or users, often used to improve video conferencing quality.

A method of combining multiple physical network interfaces into a single logical interface, increasing bandwidth and fault tolerance.

A technique that allows network devices to use larger Ethernet frames (up to 9000 bytes) for more efficient data transfer. This is especially beneficial for applications like video streaming that require large amounts of data.

A type of network topology where all devices are connected to a central hub or switch. This allows for easy communication between devices but can become a bottleneck if there is heavy traffic.

The process of limiting the bandwidth available to specific network protocols or applications, preventing them from consuming all of the network's capacity.

A network device that amplifies and forwards wireless signals, extending the range of a wireless network.

A network topology where devices connect to a central hub, which then forwards data to other devices. Think of a wheel with spokes radiating outwards.

A network topology where devices connect directly to each other, creating multiple paths for data to travel. Think of a mesh of interconnected nodes.

A network topology where devices connect to a central switch, which then forwards data to other devices based on MAC addresses. It's often used in LAN environments.

A security assessment technique that aims to identify and analyze potential vulnerabilities and weaknesses in a network or system. It helps assess security risk levels and provides recommendations for improvement.

A network address translation technique that allows multiple devices on a private network to share a single public IP address. It conserves public IP address space and enhances security.

A type of network scan that uses the ICMP protocol to identify active hosts on a network. It can be used to map a network and find devices.

A tool used to identify open ports on a network host. It can help identify services running on a host and assess potential vulnerabilities.
