Networking Concepts
This type of communication sends data from one sender to exactly one receiver on a network.
What is Unicast?
Use this to prioritize Network Traffic.
What is QOS? (Quality of Service)
plan to help ensure that business processes can continue during a time of emergency or disaster.
What is a Business Continuity Plan?
This feature is commonly used in public Wi-Fi networks, requiring users to authenticate via a web page before granting access to the internet.
What is a Captive Portal?
This type of issue can occur when the internal wires of an Ethernet cable come into contact with each other, potentially causing a loss of connection.
What is a Cable Short?
This allows multiple customers to share the same application while keeping their data isolated from each other.
What is Multitenancy?
This technology virtualizes network services like firewalls, load balancers, and routers, allowing them to run on standard hardware instead of proprietary devices.
What is Network Function Virtualization?
Use this to revert a system or process when you need to perform a major upgrade to a network device.
What is a Rollback Plan?
This open-source tool is commonly used to scan and discover devices on a network, identify open ports, and assess security vulnerabilities.
What is Nmap?
Nmap is primarily a network scanning tool used to discover devices and open ports on a network.
Wireshark is a network protocol analyzer, or "packet sniffer," that captures and inspects network traffic in real-time.
This tool is used to block or restrict access to certain websites or types of content based on predefined rules, often used in organizations to ensure safe and appropriate internet usage.
What is a Content Filter?
This VPN configuration allows users to route some of their traffic through the secure VPN tunnel while allowing other traffic to access the internet directly, without the tunnel.
What is a Split Tunnel
This Cisco proprietary routing protocol combines features of both distance-vector and link-state protocols, providing fast convergence and scalability for large networks.
What is EIGRP? (Enhanced Interior Gateway Routing Protocol)
This represents the actual measure of how much data is successfully transferred from a source to a destination in a given amount of time.
What is Throughput?
This type of attack allows an attacker to send data double-tagged packets to a VLAN through an access port access.
What is VLAN Hopping?
This command-line tool is used in Linux to query DNS servers and obtain information about domain names, such as IP addresses, MX records, and other DNS records.
What is Dig?
This technique allows multiple devices on a local network to share a single public IP address by mapping each device's private IP address to a unique port number.
What is PAT? ( Port Address Translation)
This concept refers to the ability to automatically scale resources up or down based on demand, ensuring cost efficiency and optimal performance.
What is Elasticity?
This backup site is partially operational and requires some time to become fully functional in the event of a disaster.
What is a Warm Backup Site?
This server acts as an intermediary between a user's device and the internet, often used to improve security, manage traffic, or cache content.
What is a Proxy Server?
This technique involves copying network traffic from one port to another for monitoring or analysis purposes, often used with packet sniffers.
What is Port Mirroring?
This protocol is used with Single sign-on to enable authentication and authorization for access to multiple applications and services.
What is SAML? ( Security Assertion Markup Language)
This type of wireless network utilizes the 2.4 GHz or 5 GHz frequency bands and reaches speeds of 108 Mbps to 600 Mbps
What is 802.11n?
This allow your network to handle increasing demands and grow its capacity efficiently.
What is Scalability?
This analyzes security logs from various systems across an organization to detect potential threats and security incidents in real-time.
What is a SIEM? (Security Information and Event System)
Use this to discover information about directly connected devices.
What is Link Layer Discovery Protocol?
