There have been questions about what access an application has from a DMZ zone. By default an application has no access to resources outside the cluster. This includes both internal (*.dhl.com) and external (the internet).

Tips for Prompting GenAI Hub Effectively

Be Specific

Provide clear and detailed questions. Instead of asking “Tell me about logistics,” try “What are the latest trends in logistics for 2025?”

Contextual Information

Include relevant context to your query. For example, “I’m working on a presentation about sustainable logistics practices. Can you provide some recent examples?”

Clarify your Needs

If you have a particular focus or requirement, mention it. For instance, “I need information on DHL Group’s recent sustainability initiatives.”
