Question 1 of 23

1. Question
2 points
Which two definitions accurately describe the associated application layer protocol? (Choose two.)
- SMTP - transfers web pages from web servers to clients
- Telnet - provides remote access to servers and networking devices
- DNS - resolves Internet names to IP addresses
- FTP - transfers email messages and attachments
- HTTP - enables devices on a network to obtain IP addresses
Correct

Incorrect

The Domain Name Service (DNS) protocol resolves Internet names to IP addresses. Hypertext Transfer Protocol (HTTP) transfers files that make up the web pages of the World Wide Web. The Simple Mail Transfer Protocol (SMTP) transfers mail messages and attachments. Telnet, a terminal emulation protocol, provides remote access to servers and networking devices. The File Transfer Protocol (FTP) transfers files between systems.

The application layer of the TCP/IP model performs the functions of what three layers of the OSI model? (Choose three.)
- physical
- session
- network
- presentation
- data link
- transport

Correct

Incorrect

The network access layer of the TCP/IP model performs the same functions as the physical and data link layers of the OSI model. The internetwork layer equates to the network layer of the OSI model. The transport layers are the same in both models. The application layer of the TCP/IP model represents the session, presentation, and application layers of the OSI model.

- FTP
- HTTP
- DNS
- SNMP
- DHCP

What is an example of network communication that uses the client-server model?
- A user uses eMule to download a file that is shared by a friend after the file location is determined.
- A workstation initiates an ARP to find the MAC address of a receiving host.
- A user prints a document by using a printer that is attached to a workstation of a coworker.
- A workstation initiates a DNS request when the user types www.cisco.com in the address bar of a web browser.
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.

Two students are working on a network design project. One student is doing the drawing, while the other student is writing the proposal. The drawing is finished and the student wants to share the folder that contains the drawing so that the other student can access the file and copy it to a USB drive. Which networking model is being used?
- peer-to-peer
- client-based
- master-slave
- point-to-point
Correct

Incorrect

In a peer-to-peer (P2P) networking model, data is exchanged between two network devices without the use of a dedicated server.

What do the client/server and peer-to-peer network models have in common?
- Both models have dedicated servers.
- Both models support devices in server and client roles.
- Both models require the use of TCP/IP-based protocols.
- Both models are used only in the wired network environment.
Correct

Incorrect

In both the client/server and peer-to-peer network models, clients and servers exist. In peer-to-peer networks, no dedicated server exists, but a device can assume the server role to provide information to a device serving in the client role.

What is an advantage for small organizations of adopting IMAP instead of POP?
- Messages are kept in the mail servers until they are manually deleted from the email client.
- When the user connects to a POP server, copies of the messages are kept in the mail server for a short time, but IMAP keeps them for a long time.
- IMAP sends and retrieves email, but POP only retrieves email.
- POP only allows the client to store messages in a centralized way, while IMAP allows distributed storage.
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.

When 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?
- IMAP
- POP
- SMTP
- HTTPS
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.

Which three statements describe a DHCP Discover message? (Choose three.)
- The source MAC address is 48 ones (FF-FF-FF-FF-FF-FF).
- The destination IP address is 255.255.255.255.
- The message comes from a server offering an IP address.
- The message comes from a client seeking an IP address.
- All hosts receive the message, but only a DHCP server replies.
- Only the DHCP server receives the message.
Correct

Incorrect

When a host configured to use DHCP powers up on a network it sends a DHCPDISCOVER message. FF-FF-FF-FF-FF-FF is the L2 broadcast address. A DHCP server replies with a unicast DHCPOFFER message back to the host.

Which two tasks can be performed by a local DNS server? (Choose two.)
- providing IP addresses to local hosts
- allowing data transfer between two network devices
- mapping name-to-IP addresses for internal hosts
- forwarding name resolution requests between servers
- retrieving email messages
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.

Which statement is true about FTP?
- The client can choose if FTP is going to establish one or two connections with the server.
- The client can download data from or upload data to the server.
- FTP is a peer-to-peer application.
- FTP does not provide reliability during data transmission.
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.

What is true about the Server Message Block protocol?
- Different SMB message types have a different format.
- Clients establish a long term connection to servers.
- SMB messages cannot authenticate a session.
- SMB uses the FTP protocol for communication.
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.

no dedicated server is required
client and server roles are set on a per request basis

a background service is required
devices can only function in one role at a time

peer-to-peer network

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.

Which PC or PCs are sending FTP packets to the server?

ITN Chapter 10 Exam Answers 01
- PC_3
- PC_1
- PC_2
- PC_1 and PC_3
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.
