QuestionQ4

Deployment

An implementation engineer discovers that Dell PowerProtect Data Manager is unable to add a Dell PowerProtect Data Domain appliance because the connection test fails.

What three actions should be taken to resolve this issue?

Choose three
  • A Check DD Boost service status
  • B Verify network connectivity
  • C Upgrade the Data Domain to the latest versions
  • D Reboot the Data Domain appliance
  • E Check credentials.
Explanation

A failed connection test when adding a Data Domain system to PowerProtect Data Manager is typically caused by one of three underlying issues: the DD Boost service not being enabled/running on the Data Domain (PPDM relies on DD Boost/REST connectivity to manage the system), network connectivity problems between the PPDM appliance and the Data Domain (blocked ports, DNS/name resolution issues, firewall rules), or incorrect/expired/locked credentials being used for the DD system user account. Checking and correcting these three areas — DD Boost service status, network connectivity, and credentials — resolves the vast majority of connection test failures documented in Dell's PowerProtect Data Manager troubleshooting knowledge base articles.
