System high mode is a security operating mode where all users with access to the system have security clearances that meet the highest classification level of information processed, but may not have a formal need-to-know for all data within the system.
Term 513
A system-assigned managed identity is an automatically created Azure Active Directory identity that is tied to a specific Azure resource and is used to securely authenticate to other Azure services without storing credentials.
Term 514
A table is a structured collection of data organized into rows and columns, used in databases and spreadsheets to store and manage information efficiently.
Term 515
A target group is a logical grouping of one or more backend resources, such as servers or containers, that handles incoming requests and is associated with a load balancer rule to distribute traffic.
Term 516
A target tracking policy is an AWS Auto Scaling feature that automatically adjusts the number of EC2 instances to maintain a specified target value for a given metric, such as average CPU utilization.

TCB (Trusted Computing Base) is the collection of all hardware, firmware, and software components in a system that are essential to enforcing its security policy.
Term 518
TCP (Transmission Control Protocol) is a core internet protocol that ensures data is sent reliably and in order between devices over a network.
Term 519
A TCP Proxy Load Balancer is a network device that terminates incoming TCP connections from clients, establishes a new TCP connection to a backend server, and relays data between the two, enabling advanced traffic management and security features.
Term 520
The TCP/IP model is the set of communication protocols used to connect devices on the internet and most private networks, organizing network communication into four layers.
Term 521
Telnet is a network protocol that provides a bidirectional, interactive text-based communication session between two machines over a network, typically used for remote access and management of network devices.

Term 523
Terraform on Google Cloud is an infrastructure-as-code tool that lets you define, provision, and manage Google Cloud resources using declarative configuration files instead of manual clicks or scripts.
Term 524
A DNS Text Record (TXT record) is a type of resource record that stores human-readable or machine-readable text data associated with a domain name.
Term 525
Throughput is the rate at which data is successfully transferred from one point to another over a network, typically measured in bits per second.
Term 526
Transport Layer Security (TLS) is a cryptographic protocol that encrypts data sent over the internet to keep it private and ensure it hasn’t been tampered with.
Term 527
A toner probe is a two-part tool used in networking to trace and identify specific cables within a bundle of wires, often by sending an audio signal down the wire and detecting it with a wand.
Term 528
TPM (Trusted Platform Module) is a dedicated hardware chip on a computer's motherboard that stores cryptographic keys, passwords, and certificates to secure the system against unauthorized access and tampering.
Term 529
A trace is a record of the path and timing of a request or operation as it moves through components in a system, used to monitor performance and troubleshoot issues.
Term 530
A traffic manager is a networking device or service that directs incoming data traffic across multiple servers or links to balance load, improve performance, and ensure availability.
Term 531
Traffic shaping is a network bandwidth management technique that controls the flow of data packets to ensure smooth performance and prevent congestion by intentionally delaying some traffic.
Term 532
Transactional data is information that captures a specific event or exchange, such as a sale, a payment, or a system log entry, and is recorded in a database or log system.
Term 533
A specialized hardware or virtual device used to securely and efficiently migrate large volumes of data between storage systems, often across different environments or geographic locations, without tying up production network bandwidth.
Term 534
A Transit Gateway is a network hub that connects multiple virtual private clouds (VPCs) and on-premises networks through a single, central gateway to simplify routing and reduce complexity.
Term 535
TFTP is a simple, lightweight protocol used to transfer files between devices on a network without the security and error-checking features of more robust file transfer methods.
Term 536
The trusted computing base is the entire set of hardware, firmware, and software components that are critical to a system's security, meaning that any flaw in these components can break the entire security policy.
Term 537
A Trusted Platform Module (TPM) is a dedicated microcontroller chip that securely stores cryptographic keys, passwords, and certificates to protect a computer's hardware and ensure system integrity.
Term 538
