Posted in , ,
Which two statements describe packets that are sent through a Linksys integrated router using NAT? (Choose two.)
    #Packets that are sent to a destination outside the local network need to be translated.
    #Packets that are sent between hosts on the same local network do not need to be translated.

A PC obtains its IP address from a DHCP server. If the PC is taken off the network for repair, what happens to the IP address configuration?
    #The address is returned to the pool for reuse when the lease expires.
What is the destination MAC address in a multicast Ethernet frame?
    #an address that begins with 01-00-5E in hexadecimal
How many bits are available for Class B host IP addresses using a default subnet mask?
Which default subnet mask provides the most host bits?


Refer to the graphic. NAT and DHCP are installed on the Linksys integrated router. Which IP address is most likely to be assigned to the local computer, Host1?

Refer to the graphic. The host requests an IP configuration from the Linksys integrated router which is configured to provide DHCP services. In addition to the host IP address, which additional IP address is provided that will allow the host to access the ISP and the Internet?
    #internal IP address of the integrated router that connects to the local network


Refer to the graphic. A user at the workstation cannot connect to the server. All cables have been tested and are working and all devices have IP addressing. However, the user cannot ping the server. What is causing the problem?
    #The workstation and server are on different logical networks.
Which part of an IP address identifies a specific device on a network?
    #host portion
Which type of server dynamically assigns an IP address to a host?
What is one of the purposes of NAT?
    #prevents external users from detecting the IP addresses used on a network
Assuming a default mask, which portion of the IP address represents the host?
How large are IPv4 addresses?
    #32 bits
Which statement is true concerning private IP addresses?
    #solves the issue of a finite number of available public IP addresses
Yvonne is talking to her friend on the phone. What type of message is this?

Which of the following are private IP addresses? (Choose three.)
Which three statements describe a DHCP Discover message? (Choose three.)
    #The destination IP address is
    #The message comes from a client seeking an IP address.
    #All hosts receive the message, but only a DHCP server replies.
What destination IP address is used in a unicast packet?
    #a specific host
How many usable hosts are available given a Class C IP address with the default subnet mask?
What information must be included within a unicast message for it to be delivered on an Ethernet network?
    #MAC and IP addresses that correspond to a specific destination host

A host with the IP address and a default mask belongs to what network?
