Question 6 of 23
6. Question
1 pointsWhat is an example of network communication that uses the client-server model?Correct
Incorrect
When a user types a domain name of a website into the address bar of a web browser, a workstation needs to send a DNS request to the DNS server for the name resolution process. This request is a client/server model application. The eMule application is P2P. Sharing a printer on a workstation is a peer-to-peer network. Using ARP is just a broadcast message sent by a host.Hint

Question 9 of 23
9. Question
1 pointsWhat is an advantage for small organizations of adopting IMAP instead of POP?Correct
Incorrect
IMAP and POP are protocols that are used to retrieve email messages. The advantage of using IMAP instead of POP is that when the user connects to an IMAP-capable server, copies of the messages are downloaded to the client application. IMAP then stores the email messages on the server until the user manually deletes those messages.Hint

Question 13 of 23
13. Question
1 pointsWhen retrieving email messages, which protocol allows for easy, centralized storage and backup of emails that would be desirable for a small- to medium-sized business?Correct
Incorrect
IMAP is preferred for small-to medium-sized businesses as IMAP allows centralized storage and backup of emails, with copies of the emails being forwarded to clients. POP delivers the emails to the clients and deletes them on the email server. SMTP is used to send emails and not to receive them. HTTPS is not used for secure web browsing.Hint

Question 16 of 23
16. Question
2 pointsWhich two tasks can be performed by a local DNS server? (Choose two.)Correct
Incorrect
Two important functions of DNS are to (1) provide IP addresses for domain names such as http://www.cisco.com, and (2) forward requests that cannot be resolved to other servers in order to provide domain name to IP address translation. DHCP provides IP addressing information to local devices. A file transfer protocol such as FTP, SFTP, or TFTP provides file sharing services. IMAP or POP can be used to retrieve an email message from a server.Hint

1 pointsWhich statement is true about FTP?Correct
Incorrect
FTP is a client/server protocol. FTP requires two connections between the client and the server and uses TCP to provide reliable connections. With FTP, data transfer can happen in either direction. The client can download (pull) data from the server or upload (push) data to the server.Hint

Question 19 of 23
19. Question
1 pointsWhat is true about the Server Message Block protocol?Correct
Incorrect
The Server Message Block protocol is a protocol for file, printer, and directory sharing. Clients establish a long term connection to servers and when the connection is active, the resources can be accessed. Every SMB message has the same format. The use of SMB differs from FTP mainly in the length of the sessions. SMB messages can authenticate sessions.Hint

Question 21 of 23
21. Question
4 pointsMatch a statement to the related network model. (Not all options are used.)
Sort elements
- no dedicated server is required
- client and server roles are set on a per request basis
- requires a specific user interface
- a background service is required
- devices can only function in one role at a time
-
peer-to-peer network
-
peer-to-peer network
-
peer-to-peer application
-
peer-to-peer application
Correct
Incorrect
Peer-to-peer networks do not require the use of a dedicated server, and devices can assume both client and server roles simultaneously on a per request basis. Because they do not require formalized accounts or permissions, they are best used in limited situations. Peer-to-peer applications require a user interface and background service to be running, and can be used in more diverse situations.Hint

Which PC or PCs are sending FTP packets to the server?
ITN Chapter 10 Exam Answers 01
Correct
Incorrect
After you view the details of the packets that are being transferred between each PC and the server, you will see that the PC that is using a destination port number of 20 or 21 is the PC using the FTP service. PC_2 has an outbound port number of 21 to create an FTP control session with the server at 192.168.1.253.Hint
