nslookup

What command was used to resolve a given host name by querying the name servers?

A. Messages are kept in the mail servers until the client manually deletes them.

What is an advantage for small organizations of adopting IMAP instead of POP? A. Messages are kept in the mail servers until the client manually deletes them. B. 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. C. POP only allows the client to store messages in a centralized way, while IMAP allows distributed storage. D. IMAP sends and retrieves email, but POP only retrieves email.

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

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

https

What is the acronym for the protocol that is used when securely communicating with a web server?

B. Clients establish a long term connection to servers.

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

C. when downloading large numbers of files from the same server

When would it be more efficient to use SMB to transfer files instead of FTP? A. when uploading the same file to multiple remote servers B. when a peer-to-peer application is required C. when downloading large numbers of files from the same server D. when the host devices on the network use the Windows operating system E. when downloading large files with a variety of formats from different servers

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