DER

In the Ultra Transcenders books

2V0-18.25

Each book explains DER in context, with comparison tables and the common traps.

Terms in this definition

• Certificate

  Key Vault object holding an X.509 certificate, whose associated key and secret are managed alongside it.

• FORMAT

  A DAX function that turns a value into text according to a format string, for instance "MMMM" to show a month's name. Since the output is text, numeric operations can't use it, and dynamic format strings were introduced to get around that.

• STORED AS

  In AUTO CDC, picks whether the target uses SCD Type 1 or Type 2. Without it you get Type 1, where no history is retained.

• BINARY

  A SQL type that holds raw bytes. ai_parse_document needs its content argument in this type, so passing a file path as a string does not work.

• PEM

  Text certificate format encoded in Base64. Key Vault accepts it for import, but App Service does not, so it must first be converted to PFX.

• VCF Operations orchestrator

  Engine for running workflows, previously Aria Automation Orchestrator; VCF Automation relies on it to extend its capabilities and to connect to vSphere and further systems.

• Foundry workflows

  Preview Foundry feature that orchestrates agents and logic in a fixed, declarative order, supporting variables, if/else branches and human-in-the-loop steps. Workflows are being retired on 1 December 2026 and Agent Framework replaces them.

• VCF Operations

  VCF's console for running the fleet. It covers alerting, monitoring, capacity, reporting, log analysis and licensing alongside fleet management of identity, passwords, certificates and lifecycle.

Related terms

• DER

  Encodes certificates in binary, whereas PEM uses Base64 text. Nutanix clusters accept only PEM, so run DER files through openssl before use.

• PEM

  A certificate format in Base64 text. Prism imports only this encoding, so DER files need converting first, and Move can also take a PEM private key for Linux guests.
