Refer to the exhibit. The switch cat9k-acc-1 connects users to the campus LAN. Printing services are inaccessible through the network. Which interface issue is causing the connectivity problems?

Bad checksums indicate corrupted frames which are usually dropped, but do not typically cause a port reset in the same manner as a broadcast storm.

Excessive collisions primarily occur in half-duplex environments or due to duplex mismatches, leading to frame retransmissions and drops, but not usually a port reset mechanism for network saturation.

A large number of broadcast packets can indicate a broadcast storm, which can consume significant network bandwidth, overload switch CPUs, and cause widespread network instability, potentially leading to an interface being automatically reset or put into an error-disabled state to protect the network from further disruption.

An overloaded interface output queue means the interface cannot send frames fast enough, leading to dropped packets, but doesn't inherently imply a port reset as a direct consequence in the same way a broadcast storm might.
