Zorluk: OrtaNetworking Ports and Protocols

A security technician is deploying IP surveillance cameras across a facility. The deployment policy specifies that administrators must manage the camera web portals using encrypted traffic, and all camera logs must maintain synchronized clock timestamps using a centralized network time service. Which of the following port and protocol combinations must be enabled on the network firewall to support these services? (Select TWO.)

  1. TCP port 443 for HTTPS web managementCevap
  2. UDP port 123 for Network Time Protocol (NTP)Cevap
  3. C
    TCP port 80 for HTTPS web management
  4. D
    UDP port 67 for Network Time Protocol (NTP)

Cevap

The correct port and protocol combinations are TCP port 443 for HTTPS web management and UDP port 123 for Network Time Protocol (NTP).
Secure web administrative interfaces rely on HTTPS, which uses TCP port 443 to encrypt traffic between the browser and the device. Synchronizing device logs and system clocks across a enterprise network relies on NTP, which communicates over UDP port 123.

Adım Adım Çözüm

1
Identify the service requirement for encrypted web administration
Encrypted web management requires HTTPS, which operates over TCP port 443.
Standard HTTP uses TCP port 80 without encryption, while HTTPS secures traffic using TLS on TCP port 443.
2
Identify the service requirement for time synchronization across network devices
Network time synchronization requires NTP, which operates over UDP port 123.
NTP broadcasts or unicasts time signals using UDP port 123 to ensure consistent timestamping.
