Recommended extensible attributes can be left blank.

• A. True.
• B. False.
• C. Sometimes.
• D. Only for certain attributes.

Answer: (A)

Extensible Attributes are like extra metadata fields you can attach to Infoblox objects. They come in different importance levels: some are required for certain operations or workflows, while others are optional. When an attribute is labeled as recommended, it means Infoblox suggests filling it in to improve reporting, sorting, or automation, but it isn’t required for the system to function. Therefore, you can leave a recommended extensible attribute blank without impacting core DHCP/DNS functionality. You’d populate it later if you need that additional data for governance, auditing, or specific reports. If a workflow or script relies on a particular EA, you’d fill it in for that use case, but leaving it empty won’t break standard operations.
