Comprehensive and Detailed In-Depth Explanation:CSV import in NIOS allows bulk management of objects (e.g., DNS records, networks) via structured files. Let's evaluate each statement:
* A:The Data Import Wizard (DIW) in Grid Manager (Data Management > Import) is the primary GUI tool for CSV imports, guiding admins through file upload, format selection, and validation. While WAPI can also handle CSV, DIW is the standard method, making this true in the GUI context emphasized in INE. Correct.
* B:The CSV format adheres to a standard Infoblox structure (e.g., headers like "fqdn,ip_address"), but it' s not strictly version-specific-core fields remain consistent across NIOS versions, though new features might add optional fields. Incorrect.
* C:In a CSV file, mandatory fields (e.g., "fqdn" for a host record) are marked with an asterisk (*) in the CSV template or documentation, while others (e.g., "comment") are optional. This flexibility is key for bulk operations. Correct.
* D:WAPI supports CSV import via API calls, but it's not required-DIW provides a GUI alternative.
This makes the "must" phrasing false. Incorrect.
* Practical Example:In an INE lab, you might use DIW to import a CSV with A records, ensuring only mandatory fields (marked *) are filled, troubleshooting any import errors via logs.References:Infoblox NIOS Administrator Guide - CSV Import; INE Course Objective: NIOS DDI Grid Deployment.
