Clients lack a trusted validation path to the server certificate. That does not establish vulnerability existence is being confused with observed exploitation.

Deception infrastructure could become a pivot into production. That does not establish vulnerability existence is being confused with observed exploitation.

The presented certificate does not match the requested hostname. That does not establish vulnerability existence is being confused with observed exploitation.

Enabling DHCP snooping with trusted server-facing ports and rejecting untrusted offers would not enable supported dynamic ARP inspection and valid binding checks on access switches.

Applying port security and supported MAC-table resource protections would not enable supported dynamic ARP inspection and valid binding checks on access switches.

Segment endpoints and restrict administrative protocols to authorized jump paths would not enable supported dynamic ARP inspection and valid binding checks on access switches.

DHCP assigns client network parameters through a supported lease exchange. That check cannot demonstrate correct Layer 2 next-hop resolution for the intended IP route.

Generate controlled source-MAC changes and inspect violation counters. That check cannot demonstrate correct Layer 2 next-hop resolution for the intended IP route.

SMB and NFS present shared files through file-level permissions rather than raw block devices.

DHCP assigns client network parameters through a supported lease exchange. That does not establish correct Layer 2 next-hop resolution for the intended IP route.

Limits on MAC learning reduce deliberate table exhaustion. That does not establish correct Layer 2 next-hop resolution for the intended IP route.

Malware can move laterally through broadly trusted internal protocols. That does not establish correct Layer 2 next-hop resolution for the intended IP route.

Enabling supported dynamic ARP inspection and valid binding checks on access switches would not apply port security and supported MAC-table resource protections.

Engage provider-side DDoS filtering or scrubbing would not apply port security and supported MAC-table resource protections.

Restricting trunks to known devices and avoid using sensitive native VLANs would not apply port security and supported MAC-table resource protections.

A forwarded frame uses the local next-hop MAC even when its encapsulated IP destination stays constant. That check cannot demonstrate generate controlled source-MAC changes and inspect violation counters.

Run an authorized traffic simulation and measure preserved legitimate throughput. That check cannot demonstrate generate controlled source-MAC changes and inspect violation counters.

VLAN membership and 802.1Q tagging determine which Layer 2 broadcast domain carries each frame. That check cannot demonstrate generate controlled source-MAC changes and inspect violation counters.

A forwarded frame uses the local next-hop MAC even when its encapsulated IP destination stays constant. That does not establish frame admission and MAC learning on the affected access port.

Incoming traffic volume exceeds upstream link capacity. That does not establish frame admission and MAC learning on the affected access port.

VLAN membership and 802.1Q tagging determine which Layer 2 broadcast domain carries each frame. That does not establish frame admission and MAC learning on the affected access port.

Enabling supported dynamic ARP inspection and valid binding checks on access switches would not restrict trunks to known devices and avoid using sensitive native VLANs.

Applying port security and supported MAC-table resource protections would not restrict trunks to known devices and avoid using sensitive native VLANs.

Enabling DHCP snooping with trusted server-facing ports and rejecting untrusted offers would not restrict trunks to known devices and avoid using sensitive native VLANs.

Generate controlled source-MAC changes and inspect violation counters. That check cannot demonstrate correct switch VLAN and trunk classification.

A forwarded frame uses the local next-hop MAC even when its encapsulated IP destination stays constant. That check cannot demonstrate correct switch VLAN and trunk classification.

DHCP assigns client network parameters through a supported lease exchange. That check cannot demonstrate correct switch VLAN and trunk classification.

A forwarded frame uses the local next-hop MAC even when its encapsulated IP destination stays constant. That does not establish correct switch VLAN and trunk classification.

Limits on MAC learning reduce deliberate table exhaustion. That does not establish correct switch VLAN and trunk classification.

Anti-tailgating policy lacks an enforceable entry control. That does not establish correct switch VLAN and trunk classification.

Enabling DHCP snooping with trusted server-facing ports and rejecting untrusted offers would not address the need for harden recursive resolver validation and use DNSSEC where supported.

Using certificate-validated enterprise authentication and monitoring for rogue APs would not address the need for harden recursive resolver validation and use DNSSEC where supported.

Rejecting invalid server identity and using authenticated encrypted sessions would not address the need for harden recursive resolver validation and use DNSSEC where supported.
