An administrator manages the zone example.com in an Infoblox Grid. The new domain marketing.example. com will have its own set of name servers that are not part of the same Infoblox Grid. Which type of zone should the administrator configure in NIOS for marketing.example.com?
Correct Answer: B
Comprehensive and Detailed In-Depth Explanation:Configuring a subdomain like marketing.example.com in NIOS: * Scenario:example.com is authoritative on the Grid, but marketing.example.com uses external name servers (not Grid-managed). * B (Delegated Zone):A delegation zone adds NS records pointing to external servers (e.g., ns1. marketing.com), handing off resolution. Correct. * A:Authoritative means the Grid hosts the zone's records-not true here. Incorrect. * C:Subzone isn't a NIOS term-implies authoritative control, not delegation. Incorrect. * D:External zone isn't a configuration option-confuses forward zones. Incorrect. * Practical Example:In an INE lab, you'd delegate marketing.example.com with NS records, test resolution, and troubleshoot DNS handoff.References:Infoblox NIOS Administrator Guide - DNS Delegation; INE Course Content: NIOS DDI DNS Troubleshooting.
