TFTP stands for:

Trigger Flash Telnet Protection
Tunnel Filing Translation Protocol
Trivial File Transfer Protocol
The Fun Time Party

Correct Answer

A. Trivial File Transfer Protocol

Explanation

TFTP stands for Trivial File Transfer Protocol. This protocol is a simple file transfer protocol that is commonly used for transferring files between network devices. It is often used in situations where a more complex protocol such as FTP is not necessary or feasible. TFTP operates on UDP and provides basic file transfer capabilities, making it suitable for small-scale file transfers in local area networks.

69
72
73 and 75
No assigned port

Correct Answer

A. 69

Explanation

TFTP (Trivial File Transfer Protocol) is assigned to port number 69. This port is used for transferring files between clients and servers in a network. TFTP is a simple and lightweight protocol that operates at the transport layer of the TCP/IP model. It is commonly used for booting diskless workstations, transferring firmware updates, and transferring configuration files to network devices.

DHCP uses which TWO ports?

65
66
67
68
69

Correct Answer(s)

A. 67
A. 68

Explanation

DHCP (Dynamic Host Configuration Protocol) uses port numbers 67 and 68. Port 67 is used by DHCP servers to listen for client requests and allocate IP addresses, while port 68 is used by DHCP clients to send requests and obtain IP addresses from DHCP servers. These port numbers are standardized and commonly used for DHCP communication.

In the list below, which choice has both of the Mail Recieving Protocols with their proper assigned port numbers? (READ THE WHOLE ANSWER!)

SMTP: 25, IMAP: 143
IMAP: 134, POP3: 110
SMTP: 25, POP3: 110
HTTPS: 443, SMTP: 25
IMAP: 143, POP3, 110

Correct Answer

A. IMAP: 143, POP3, 110

Explanation

The correct answer is "IMAP: 143, POP3: 110". This answer correctly identifies the assigned port numbers for both IMAP and POP3 protocols. IMAP uses port 143 for mail retrieval, while POP3 uses port 110. The other choices either have incorrect port numbers or do not include both protocols.

Check all port numbers used by NETBIOS:

135
136
137
138
139
140
141
445

Correct Answer(s)

A. 135
A. 137
A. 138
A. 139
A. 445

Explanation

NETBIOS (Network Basic Input/Output System) is a protocol used for communication between computers on a local area network (LAN). The given answer lists the port numbers used by NETBIOS. Port 135 is used for the Remote Procedure Call (RPC) endpoint mapper, which allows clients to inquire about the services available on a server. Ports 137 and 138 are used for the NETBIOS name service, which resolves NetBIOS names to IP addresses. Port 139 is used for file and printer sharing, while port 445 is used for the Server Message Block (SMB) protocol, which enables file sharing and other network services.

Port 22 is used for?

Open slot saved for Port Triggering
Is not used
DNS
SSH
Owned by Microsoft and not made available for private use
Correct answer not provided on this check list

Correct Answer

A. SSH

Explanation

Port 22 is used for SSH (Secure Shell), which is a network protocol that provides a secure way to access and manage remote systems. SSH allows users to establish a secure and encrypted connection to a remote server, providing authentication and data encryption. It is commonly used by system administrators and developers to remotely access and control servers, as well as for secure file transfers.

Check all that apply for DNS:

Uses port 51
Uses Port 52
Uses Port 53
Turns URLS into IP Addresses
Turns IP Addresses into URLS

Correct Answer(s)

A. Uses Port 53
A. Turns URLS into IP Addresses

Explanation

DNS (Domain Name System) is a protocol that is responsible for translating domain names (URLs) into IP addresses and vice versa. It uses Port 53 to communicate between DNS servers and clients. Therefore, the correct answers are "Uses Port 53" and "Turns URLs into IP Addresses".

SMTP uses wich port to send mail?

23
24
25
225

Correct Answer

A. 25

Explanation

SMTP (Simple Mail Transfer Protocol) uses port 25 to send mail. This is the default port for SMTP communication. SMTP is a protocol used for sending and receiving emails over the internet. Port 25 is specifically designated for SMTP and is used by mail servers to establish a connection and send emails to other mail servers.

HTTPS is the protocol to use port 443?

True
False

Correct Answer

A. True

Explanation

HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP that uses encryption to protect the data being transmitted. By default, HTTPS uses port 443 for communication. This is because port 443 is designated for secure communication and is commonly used for HTTPS connections. Therefore, the statement that HTTPS uses port 443 is true.

Port used to browse the web:

80
8080
8088

Correct Answer

A. 80

Explanation

Port 80 is the standard port used for browsing the web. When a user enters a URL in their web browser, the browser sends a request to the web server on port 80. The web server then responds with the requested web page, which is displayed in the browser. Port 80 is commonly used for HTTP (Hypertext Transfer Protocol) communication, which is the protocol used for transmitting web pages and other web resources over the internet. Therefore, port 80 is the correct answer for the port used to browse the web.

Port Triggering and port forwarding can be used on which port(s)?

80
8080
8088
8888

Correct Answer(s)

A. 8080
A. 8088

Explanation

Port triggering and port forwarding can be used on ports 8080 and 8088. These techniques are used to redirect incoming network traffic to specific ports on a local network. Port triggering is a dynamic method where a specific outgoing connection triggers the opening of a specific incoming port, while port forwarding is a static method that permanently redirects incoming traffic from a specific port to a designated device on the network. In this case, both port 8080 and 8088 can be used for port triggering and port forwarding.
