Explanation

The problem is that management traffic is competing with production traffic on the same physical NIC, causing the admin to lose connectivity when the network is saturated. Answer B (install a management NIC and dedicated virtual switch) is correct because it creates an out-of-band management channel - a completely separate physical and virtual network path dedicated solely to management traffic that is isolated from production load. Option A (increasing RAM) addresses I/O performance but not network congestion. Option C (FCoE vs. iSCSI) changes the storage protocol but does not address the management network issue. Option D (moving the test web server) reduces load slightly but does not guarantee uncontested management access. Out-of-band management is a best practice for exactly this reason.
