A storage administrator is troubleshooting lack of connectivity between an iSCSI-initator and iSCSI-target that is located behind a firewall. The firewall has the following active rule base:
Allow udp port 3260
Allow tcp port 443
Allow icmp all
Deny all
Which of the following is the MOST likely issue?
A.
iSCSI does not function behind a firewall due to the RPC protocol.
B.
iSCSI also requires TCP/3260 to be allowed.
C.
The issue is not firewall related as iSCSI is not a TCP/IP-based protocol.
D.
iSCSI does not function behind a firewall due to NAT requirements.
