A VLAN mismatch occurs when two connected network devices are configured with different VLAN assignments on the same link, causing traffic to be dropped or misrouted.
Term 542
VLAN tagging is a method used to identify which VLAN a network frame belongs to as it travels across a trunk link, allowing multiple VLANs to share the same physical connection without mixing their traffic.
Term 543
A VM scale set is a cloud computing service that automatically manages a group of identical virtual machines that can increase or decrease in number based on demand.
Term 544
VM size is the specific combination of virtual CPU cores, memory, and sometimes temporary storage that defines the capacity and performance of a virtual machine in a cloud environment.
Term 545
A virtual private network inside a cloud provider that lets you securely connect and isolate your cloud resources.
Term 546
VNet peering is a networking connection that links two virtual networks so they can communicate with each other as if they were a single network.
Term 547
A Voice VLAN is a separate virtual local area network configured on a network switch to carry voice traffic, such as from IP phones, ensuring quality of service and security by isolating it from data traffic.
Term 548
A Virtual Private Cloud (VPC) is a logically isolated section of a cloud provider's network where you can launch and manage resources like servers and databases with complete control over IP addressing, subnets, route tables, and security.
Term 549
A VPC endpoint is a private connection that allows resources inside a Virtual Private Cloud to access supported AWS services or external networks without going over the public internet.
Term 550
A Virtual Private Cloud (VPC) network is a logically isolated section of a public cloud provider's infrastructure where you can launch cloud resources in a virtual network that you define and control.
Term 551
VPC peering is a direct network connection between two virtual private clouds that allows them to communicate using private IP addresses as if they were part of the same network.
Term 552
A VPN (Virtual Private Network) creates a secure, encrypted tunnel between your device and a remote server, protecting your data and hiding your online activity.
Term 553
A VPN concentrator is a network device that manages, encrypts, and routes multiple VPN connections from remote users or sites into a single secure gateway.
Term 554
A VPN Gateway is a network device or service that creates an encrypted tunnel between two or more networks over the internet, allowing secure communication.
Term 555
A vulnerability is a weakness in a system, network, or software that could be exploited by a threat to cause harm or unauthorized access.
Term 556
A vulnerability assessment is a systematic review of security weaknesses in an information system, evaluating if the system is susceptible to any known vulnerabilities, assigning severity levels, and recommending remediation or mitigation.
Term 557
Vulnerability management is the continuous process of identifying, classifying, prioritizing, and remediating security weaknesses in an organization's IT environment.
Term 558
A vulnerability scan is an automated process that checks systems, networks, and applications for known security weaknesses or misconfigurations.
Term 559
A Web Application Firewall (WAF) is a security tool that monitors, filters, and blocks HTTP traffic to and from a web application to protect it from common attacks.
Term 560
Weighted routing is a traffic management technique that distributes network requests across multiple servers or paths according to assigned numerical weights, allowing for controlled, uneven load distribution.
Term 561
Windows Defender Firewall is a built-in security feature in Microsoft Windows that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
Term 562
A wireless access point is a networking device that allows Wi-Fi-enabled devices to connect to a wired network, typically a local area network (LAN), acting as a bridge between wireless and wired communication.
Term 563
XDR, or Extended Detection and Response, is a unified security platform that collects and correlates data across multiple security layers—endpoints, networks, servers, cloud workloads, and email—to improve threat detection and enable faster response.
Term 564
Yum (Yellowdog Updater Modified) is a command-line package management tool used in Red Hat-based Linux distributions to install, update, remove, and manage software packages from repositories.
Term 565
Zone-redundant storage is a data replication method that stores copies of your data in multiple physical locations within a cloud region, so your data remains safe and available even if one entire data center fails.
Term 566
ZRS (Zone Redundant Storage) is a data storage option in Microsoft Azure that automatically replicates your data across multiple physical locations within a single region to keep it safe even if an entire data center goes down.
