Permitting supported SIP signaling on the configured 5060 or TLS 5061 path would not configure approved NTP sources and permit UDP 123 as required.

Allowing SMB only on the explicitly approved internal host path would not configure approved NTP sources and permit UDP 123 as required.

Permitting DHCP relay flows for the appropriate server and client endpoints would not configure approved NTP sources and permit UDP 123 as required.

Correct INVITE and successful call setup verify signaling. It does not compare clock offset before and after polling an authorized source.

DHCP assigns client network parameters through a supported lease exchange. It does not compare clock offset before and after polling an authorized source.

TCP connections require an accepted SYN, SYN-ACK and ACK exchange before application requests. It does not compare clock offset before and after polling an authorized source.

DHCP assigns client network parameters through a supported lease exchange. That does not establish completion of the TCP three-way handshake.

TCP connections require an accepted SYN, SYN-ACK and ACK exchange before application requests. The missing change involves time synchronization needs a reachable time source.

Call setup signaling is separate from media transport. That does not establish completion of the TCP three-way handshake.

Configuring trap destinations and allowing UDP 162 to the monitoring receiver would not enforce HTTPS over TCP 443 with valid certificates and HSTS where suitable.

Allowing SMB only on the explicitly approved internal host path would not enforce HTTPS over TCP 443 with valid certificates and HSTS where suitable.

Permitting DHCP relay flows for the appropriate server and client endpoints would not enforce HTTPS over TCP 443 with valid certificates and HSTS where suitable.

Success and isolation validate narrow file-sharing policy. That check cannot demonstrate attempt plaintext access and verify redirect or rejection plus valid TLS.

DHCP assigns client network parameters through a supported lease exchange. That check cannot demonstrate attempt plaintext access and verify redirect or rejection plus valid TLS.

Arrival at UDP 162 validates asynchronous notification. That check cannot demonstrate attempt plaintext access and verify redirect or rejection plus valid TLS.

Telnet exposes management credentials and commands in plaintext. The missing change involves allow only approved RDP TCP 3389 via the controlled access gateway.

SMB operates over a distinct file-service port. That does not establish completion of the TCP three-way handshake.

Permitting appropriate DNS traffic on TCP and UDP 53 for approved resolvers would not allow only approved RDP TCP 3389 via the controlled access gateway.

Protected handshake and encrypted payload demonstrate secure CLI. It does not test RDP from approved management addresses and deny untrusted sources.

Success and isolation validate narrow file-sharing policy. It does not test RDP from approved management addresses and deny untrusted sources.

TCP connections require an accepted SYN, SYN-ACK and ACK exchange before application requests. It does not test RDP from approved management addresses and deny untrusted sources.

Telnet exposes management credentials and commands in plaintext. That does not establish the requested service uses RDP rather than SSH.

SMB operates over a distinct file-service port. That does not establish the requested service uses RDP rather than SSH.

TCP connections require an accepted SYN, SYN-ACK and ACK exchange before application requests. That does not establish the requested service uses RDP rather than SSH.

Permitting supported SIP signaling on the configured 5060 or TLS 5061 path would not configure trap destinations and allow UDP 162 to the monitoring receiver.

Allowing only approved RDP TCP 3389 via the controlled access gateway would not configure trap destinations and allow UDP 162 to the monitoring receiver.

Permitting DHCP relay flows for the appropriate server and client endpoints would not configure trap destinations and allow UDP 162 to the monitoring receiver.

Success and isolation validate narrow file-sharing policy. That check cannot demonstrate generate an authorized test interface event and observe the trap.

DHCP assigns client network parameters through a supported lease exchange. That check cannot demonstrate generate an authorized test interface event and observe the trap.

Test RDP from approved management addresses and deny untrusted sources. That check cannot demonstrate generate an authorized test interface event and observe the trap.

Unauthenticated plaintext web access is permitted for sensitive sessions. That does not establish sNMP traps use UDP 162 rather than poll UDP 161.

Call setup signaling is separate from media transport. That does not establish sNMP traps use UDP 162 rather than poll UDP 161.

The requested service uses RDP rather than SSH. That does not establish sNMP traps use UDP 162 rather than poll UDP 161.
