   Which of the following protocols operates without a port number assignment?

   • ASNMP
   • BTCP
   • CSSH
   • DDHCP

   Show answer

   Answer: B

   Explanation

   The correct answer is D. DHCP. DHCP (Dynamic Host Configuration Protocol) operates without a port number assignment. DHCP is a protocol used for assigning IP addresses and other network settings to devices on a network. It uses a broadcast mechanism to communicate with devices, and therefore does not require a specific port number assignment. Here's why the other options are incorrect: A. SNMP (Simple Network Management Protocol) typically uses ports 161 and 162 for communication. B. TCP (Transmission Control Protocol) is a transport-layer protocol that uses port numbers to identify specific applications and services. C. SSH (Secure Shell) typically uses port 22 for secure remote access and management. DHCP's broadcast mechanism allows it to operate without a specific port number assignment, making it the correct answer.

   A technician replaces a CPU and then notices the fans are continuously running. The computer randomly crashes after about five minutes. Which of the following should the technician do to prevent this issue from reoccurring?

   • AApply thermal paste.
   • BUse Trusted Platform Module.
   • CReplace the socket.
