Citrix Certified Expert - Virtualization: Assessment and Design key terms
Citrix Certified Expert - Virtualization: Assessment and Design · Get comfortable with the vocabulary.
- User segmentation
Grouping users by relevant workloads, locations, endpoints and requirements so design and testing represent meaningful differences instead of an assumed average user.
- Acceptance criterion
An agreed observable condition used to decide whether a requirement is met, with the workload, measurement and context defined before the test.
- Requirements traceability
A recorded connection between each requirement, the design decision addressing it and the evidence or test used to validate the result.
- Design constraint
A limit on available design choices, such as an approved hosting platform or required identity integration, distinguished from an untested assumption.
- Resource enumeration
The process of identifying and presenting resources available to an authenticated user, distinct from establishing the eventual application or desktop session.
- Brokering
Selecting and arranging a suitable eligible resource for a launch through the delivery infrastructure, rather than rendering every frame of an established session.
- Federated Authentication Service
A Citrix service supporting certificate-based VDA single sign-on in a configured trusted architecture when the original authentication does not provide Windows credentials.
- HDX data path
The actual network route carrying session interaction between endpoint and workload through the components selected for that deployment architecture.
- Machine assignment
The rule determining which machine a user receives, which must be considered separately from disk persistence and the storage of personal user state.
- Profile persistence
Retention of relevant user settings and data across sessions through an appropriately supported profile design, not a substitute for protected backups.
- Image rollback
Returning machines to a previously prepared image state through a supported process, with separate consideration of user data and infrastructure changes.
- Provisioning dependency
A service, storage, network or configuration requirement needed for the chosen machine/image delivery mechanism to work as intended.
- Machine catalog
A grouping of machines with relevant shared characteristics and provisioning arrangements, from which compatible machines can be allocated for resource delivery.
- Delivery group
An object defining delivered resources and access using machines selected from compatible catalogs, with each machine belonging to one delivery group at a time.
- Administrative role
A defined set of management activities an administrator may perform, applied together with scopes identifying the objects under that permission.
- Resulting policy
The effective settings for the applicable machine or session after evaluating relevant policy sources, scopes, filters and precedence rather than inspecting one definition.
- Representative workload
A test workload reflecting the important actual application, concurrency, user and operating conditions for which the design must provide service.
- Failure headroom
Additional usable capacity that allows a design to meet a defined demand after the specified component or fault-domain loss.
- Fault domain
A set of components sharing a potential failure cause, such as a physical host, storage service or network dependency.
- Launch burst
A concentrated arrival of session or machine-start requests that can stress dependencies differently from a stable population of already running sessions.
- Recovery time objective
The agreed target duration for restoring the defined usable service after a specified disruption, including relevant dependencies and validation.
- Recovery point objective
The agreed limit on lost data or changes measured back from a disruption to a suitable recoverable point.
- Connection lease
Information used by supported Workspace service-continuity mechanisms for resource launch during particular outages, distinct from a full replica of the site configuration.
- Recovery runbook
A documented set of decisions, responsibilities, steps, dependencies and verification actions for restoring and returning a defined service to normal operation.
