Which port does LDAPS use?

Explanation
LDAPS (Lightweight Directory Access Protocol over Secure Socket Layer) is a protocol used to secure communications between a client and a directory server. It uses port 636 to establish a secure connection between the client and the server. By default, LDAPS encrypts the data transmitted over the network, ensuring the confidentiality and integrity of the information exchanged. Therefore, the correct answer is 636.

Which ports does DHCP use?

Explanation
DHCP (Dynamic Host Configuration Protocol) uses ports 67 and 68. Port 67 is used by DHCP servers to listen for client requests and respond with IP configuration information, while port 68 is used by DHCP clients to send requests and receive responses from DHCP servers. These ports are reserved specifically for DHCP communication, allowing for efficient and reliable communication between clients and servers in a network.

Which ports does NetBIOS use?

Explanation
NetBIOS (Network Basic Input/Output System) is a protocol that allows applications on different computers to communicate over a local area network (LAN). It uses ports 135-139 to establish communication between devices. Port 135 is used for the Remote Procedure Call (RPC) endpoint mapper, which helps in locating services on a network. Ports 136-139 are used for various NetBIOS services like file sharing, name resolution, and session establishment. Therefore, the correct answer is 135-139.

7.

Which ports does SNMP use?

Explanation
SNMP (Simple Network Management Protocol) uses ports 161 and 162. Port 161 is used for SNMP queries and requests, while port 162 is used for SNMP traps, which are notifications sent by network devices to a management system. These ports are standardized and commonly used for SNMP communication between network devices and management systems.

Which ports does HTTPS use?

Explanation
HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP that uses encryption to protect the data being transmitted. It operates on port 443, which is specifically designated for secure web communication. By using this port, HTTPS ensures that the data exchanged between a web server and a client is encrypted and cannot be easily intercepted or tampered with by malicious actors. Therefore, port 443 is the correct answer for the question.

What ports does MGCP use?

Explanation
MGCP (Media Gateway Control Protocol) uses ports 2427-2727. This protocol is used for controlling media gateways in a Voice over IP (VoIP) network. The range of ports mentioned in the answer is the standard port range for MGCP communication. These ports are used for transmitting signaling and control messages between the media gateway and the call control server. By using these specific ports, MGCP ensures that the communication between the media gateway and the call control server is properly established and maintained.

10.

What ports does SIP (Session Initiation Protocol) use?

Explanation
SIP (Session Initiation Protocol) uses ports 5060-5061. This means that SIP communication typically occurs over these ports, allowing devices and applications to initiate and manage sessions, such as voice and video calls, over an IP network. Using this port range ensures that SIP traffic can flow smoothly and be properly routed between different devices and networks.
