Term 541
A device that provides emergency power to connected equipment when the main power source fails or drops to an unacceptable voltage level.
Term 542
Universal Plug and Play is a set of networking protocols that allows devices on a network to discover each other and connect automatically without manual configuration.
Term 543
An unmanaged instance group is a collection of virtual machine instances that you manage individually, without the automatic scaling, healing, and rolling update features provided by managed instance groups.
Term 544
Unshielded Twisted Pair (UTP) is a type of copper cabling used in Ethernet networks, where pairs of wires are twisted together to reduce electrical interference, without additional metallic shielding.
Term 545
Unstructured data is information that does not have a predefined data model or is not organized in a predefined manner, making it difficult for traditional databases to read and process.
Term 546
An update domain is a logical grouping of resources in a cloud or datacenter environment that can be patched or updated together without causing downtime to the entire application.
Term 547
Update management is the process of controlling and deploying software patches and updates to keep systems secure, stable, and compliant.
Term 548
An uptime check is a monitoring test that verifies whether a system or service is running and accessible over a network.
Term 549
User Datagram Protocol (UDP) is a fast, connectionless network protocol that sends data without first checking if the receiver is ready or if the data arrived safely.
Term 550
A user-assigned managed identity is a standalone Azure identity that can be assigned to one or more Azure resources, enabling them to authenticate to other services without storing credentials.
Term 551
A user-defined route (UDR) is a custom routing rule you create in a cloud or on-premises network to override or supplement the system's default routing behavior, directing network traffic along a specific path.
Term 552
A Variable Length Subnet Mask (VLSM) allows network engineers to divide an IP address space into subnets of different sizes, using different subnet masks for each subnet to match the exact number of hosts needed.
Term 553
Vertex AI is a unified platform from Google Cloud that lets you build, deploy, and scale machine learning models using a single set of tools and services.
Term 554
A view is a saved query in a database that acts like a virtual table, letting you see specific data without storing it separately.
Term 555
Virtual Extensible LAN (VXLAN) is a network virtualization technology that uses encapsulation to create isolated, scalable, Layer 2 networks across a Layer 3 infrastructure.
Term 556
A Virtual IP (VIP) is a floating IP address shared among multiple servers or network devices to provide high availability and fault tolerance without being tied to a single physical interface.
Term 557
A virtual network is a software-based network that connects computers, servers, and devices over the internet or within a cloud environment, simulating a physical network without requiring dedicated hardware.
Term 558
Virtual Routing and Forwarding (VRF) is a technology that lets a single physical router operate as if it were multiple independent routers, each keeping its own separate routing table.
Term 559
Virtualization security is the practice of protecting virtualized environments including virtual machines, hypervisors, virtual networks, and related infrastructure from threats and vulnerabilities.
Term 560
Vision AI is a Google Cloud service that uses machine learning to analyze images and videos, extracting meaningful information without requiring custom model building.
Term 561
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 562
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 563
A virtual private network inside a cloud provider that lets you securely connect and isolate your cloud resources.
Term 564
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 565
Voice over IP (VoIP) is a technology that lets you make phone calls using an internet connection instead of a traditional telephone line.
Term 566
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 567
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 568
A feature that captures information about the IP traffic going to and from network interfaces in a Virtual Private Cloud (VPC).
Term 569
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 570
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.
