Exam 200-301 topic 1 question 71 discussion

HTTP SMTP Telnet (can be used to test tcp connectivity not udp) DNS RTP SNMP DNS is mostly UDP Port 53, but as time progresses, DNS will rely on TCP Port 53 more heavily. DNS has always been designed to use both UDP and TCP port 53 from the start1 , with UDP being the default, and fall back to using TCP when it is unable to communicate on UDP, typically when the packet size is too large to push through in a single UDP packet.

TCP- HTTP, SMTP, Telnet UDP- DNS, RTP, SNMP

DNS uses UDP, and SMTP uses UDP.

given answers are incorrect TCP: HTTP SMTP Telnet UDP: DNS RTP SNMP

SMTP are typically uses TCP port 25 for communication DNS primarily uses UDP as its transport protocol, specifically on port 53. UDP is preferred for DNS because it is faster and more efficient for simple queries, where a reliable connection is not necessary. However, DNS can also use TCP for larger queries or zone transfer operations that exceed the 512-byte limit of UDP packets.

DNS utilize UDP for query and TCP for estabilishe a connection. In my Opinion the correct answer is TCP -> HTTP, Telnet and SMTP UDP -> DNS, SNMP, RTP

This choice will be the consensus. TCP: HTTP, SMTP, and Telnet UDP: DNS, RTP, SNMP

RTP was the one that got me here. 1stly was it Real Time Transport protocol or Reliable Transport Protocol? On review I think its Real TIme Transport Protocol. This matches with the consensus TCP - HTTP, SMTP, Telnet UDP - DNS, RTP, SNMP 1st post complete, happy days....

the correct answer is not coerrect !! SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending and receiving email.

i think it is typo ,,, DNS should under UDP NOT TCP HTTP SMTP Telnet DNS RTP SNMP

SMTP uses TCP port 25. DNS uses both UDP and TCP, but each differently. It uses UDP for normal DNS queries by users because DNS has to be really fast, and TCP for bulk queries such as zone transfers between DNS servers. So the accurate answer is: TCP- HTTP, SMTP, TELNET UDP - DNS, RTP, SNMP

The question reads "primary transfer protocol". I am certain DNS would have UDP considered as its primary. Also, SMTP uses TCP for its protocol. So I believe the DNS (under TCP) and SMTP (under UDP) need to be swapped in the Correct Answer for it to be actually correct.

"primary transmission protocols" DNS uses UDP firstly then uses TCP in case. HTTP SMTP Telnet/SSH DNS RTP SNMP

RTP use UDP, the answer is incorrect. correct me if i am wrong.

TCP - HTTP, SMTP, Telnet,FTP, SSH, POP3, HTTPS UDP - DHCP, DHCP(client), TFTP, SNMP, TCP & UDP - DNS (53)

SMTP is TCP port 25. SMTP should be in TCP bracket not in UDP. DNS is UDP/TCP port 53. However it is initially UDP unless the messages are larger than 512 bytes then it will use TCP.

TCP:SMTP, Telnet, HTTP UDP: RTP, DNS, SNMP
