During the discovery step of implementation, an unconfigured PowerStore is unavailable. Which firewall ports must be open for a successful discovery?

Question

Options

• ATCP port 5353 and UDP port 5353
• BTCP port 8443 and UDP port 5353
• CTCP and UDP ports 443 and 80
• DTCP port 80 and UDP port 80

• A
  93% (40)
• B
  2% (1)
• D
  5% (2)

Explanation

Option A is correct because discovering an unconfigured PowerStore relies on mDNS (multicast DNS), which operates on port 5353 for both TCP and UDP - this is the protocol PowerStore Manager uses to detect unconfigured nodes broadcasting on the local network segment. Option B is wrong because TCP 8443 is a management/API port used after a device is already configured and reachable, not for initial mDNS-based discovery. Option C is wrong because TCP/UDP 443 and 80 (HTTPS/HTTP) are used for configured PowerStore management communication, not for broadcasting/discovery of unconfigured units. Option D is wrong because UDP port 80 is not a standard protocol assignment - port 80 is an HTTP port that runs over TCP, making this combination technically invalid and irrelevant to discovery.

Memory tip: Think "5353 = mDNS = finding strangers" - just like your phone uses mDNS (Bonjour/Avahi) to find unknown devices on a local network, PowerStore uses the same port 5353 to announce itself before it has an IP or configuration. If it's unconfigured, it can't speak HTTPS (443) yet - it speaks mDNS first.
