HTTPS

Which application layer protocol uses message types such as GET, PUT, and POST? DNS DHCP SMTP HTTP POP3

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

peer-to-peer

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 application

session presentation application

What part of the URL, http://www.cisco.com/index.html, represents the top-level DNS domain? .com www http index

.com

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.

A workstation initiates a DNS request when the user types www.cisco.com in the address bar of a web browser.

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.

Both models support devices in server and client roles.

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.

Clients establish a long term connection to servers.

A manufacturing company subscribes to certain hosted services from their ISP. The services required include hosted world wide web, file transfer, and e-mail. Which protocols represent these three key applications? (Choose three.) FTP HTTP DNS SNMP DHCP SMTP

FTP HTTP SMTP

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

IMAP

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.

Messages are kept in the mail servers until they are manually deleted from the email client.

Perform the tasks in the activity instructions and then answer the question.Which PC or PCs are sending FTP packets to the server? PC_3 PC_1 PC_2 PC_1 and PC_3

PC_2

Match a statement to the related network model. Peer-to-peer network Peer-to-peer application -no dedicated server is required -client and server roles are set on a per request basis -peer-to-peer application -requires a specific user interface -a background service is required

Peer-to-peer network: no dedicated server is required client and serve roles are set on a per request basis Peer-to-peer application: requires a specific user interface a background service is required

Which application layer protocol is used to provide file-sharing and print services to Microsoft applications? HTTP SMTP DHCP SMB

SMB

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

Telnet - provides remote access to servers and networking devices DNS - resolves Internet names to IP addresses

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.

The client can download data from or upload data to the server.

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.

The destination IP address is 255.255.255.255. The message comes from a client seeking an IP address. All hosts receive the message, but only a DHCP server replies.

Which layer in the TCP/IP model is used for formatting, compressing, and encrypting data? internetwork session presentation application network access

application

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

mapping name-to-IP addresses for internal hosts forwarding name resolution requests between servers

What are two characteristics of the application layer of the TCP/IP model? (Choose two.) responsibility for logical addressing responsibility for physical addressing the creation and maintenance of dialogue between source and destination applications closest to the end user the establishing of window size

the creation and maintenance of dialogue between source and destination applications closest to the end user

What is the function of the Nslookup utility? to manually query the name servers to resolve a given host name to view the network settings on a host to manually force a client to send a DHCP request to display all cached DNS entries on a host

to manually query the name servers to resolve a given host name

Match the functions to the name of the application. Telnet DHCP DNS IMAP HTTP SMTP FTP maps URLs to numerical addresses dynamically assigns IP address to clients display web pages allows viewing of messages on email clients sends email messages

DHCP -> dynamically assigns IP address to clients DNS -> maps URLs to numerical addresses IMAP -> allows viewing of messages on email clients HTTP -> displays web pages SMTP -> sends email messages
