Which type of server dynamically assigns an IP address to a host?
A dhcp server
Which statement describes the relationship of a physical network and logical IPv4 addressed networks?
A physical network can connect multiple devices of different IPv4 logical networks.
What is one advantage of using DHCP to assign addresses to mobile devices?
Address leases are temporary and are returned to the pool when the device is turned off.
What are two features of IPv4 addresses? (Choose two.)
An IPv4 addressing scheme is hierarchical and IPv4 is a logical addressing scheme.
A host PC is attempting to lease an address through DHCP. What message is sent by the server to let the client know it is able to use the provided IP information?
DHCPDISCOVER message and the DHCPREQUEST message.
What criterion must be followed in the design of an IPv4 addressing scheme for end devices?
Each IP address must be unique within the local network.
Which statement describes one purpose of the subnet mask setting for a host?
It is used to determine to which network the host is connected.
Which technology enables devices in an IPv6-only network to communicate with devices in an IPv4-only network?
NAT64
two parts of IPV4 address
Network and host portions
What does a double colon (::) represent in an IPv6 address notation?
a continuous string of one or more hextets that contain only zeros
A host is transmitting a broadcast. Which host or hosts will receive it?
all hosts in the same network
Which type of packet is sent by a DHCP server after receiving a DHCP Discover message?
dhcp offer
Which message does an IPv4 host use to reply when it receives a DHCPOFFER message from a DHCP server?
dhcp request
A message is sent to all hosts on a remote network. Which type of message is it?
directed broadcast
A PC is configured with both an IPv4 and IPv6 address on the same network adapter. What IPv4 and IPv6 coexistence strategy is implemented on the PC?
dual stack
Which two reasons generally make DHCP the preferred method of assigning IP addresses to hosts on large networks? (Choose two.)
eliminates address configuration errors and reduces the burden on network support staff.
A user is unable to access the company server from a computer. On issuing the ipconfig command, the user finds that the IP address of the computer is displayed as 169.254.0.2. What type of address is this?
link local
What is the role of IANA?
managing the allocation of IP addresses and domain names
What is an advantage of using IPv6 ?
more addresses for networks and hosts
What are two methods that can be used to shorten the IPv6 address notation? (Choose two.)
omit all leading zeros from all hextets in the address and use of a double colon (::) to represent a string of all zero hextets
Which network device can serve as a boundary to divide a Layer 2 broadcast domain?
router
The network design requires multiple logical networks be deployed on one physical network. Which technology is required to enable computers on different logical networks to communicate with each other?
routing
What is the purpose of the subnet mask in conjunction with an IP address?
to determine the subnet to which the host belongs
What is one reason for subnetting an IP network?
to reduce the scope of broadcast flooding
What was the reason for the creation and implementation of IPv6?
to relieve IPv4 address depletion
Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures?
tunneling
