Networking essentials 9-12
Which destination IPv4 address does a DHCPv4 client use to send the initial DHCP Discover packet when the client is looking for a DHCP server?
255.255.255.255
DHCP (Dynamic Host Configuration Protocol)
A network service that provides automatic assignment of IP addresses and other TCP /IP configuration information.
True or False: 4 out of 5 RIRs no longer have enough IPv4 addresses to allocate to customers on a regular basis.
False
static addressing
The process of assigning IP addresses by manually typing them into client computers.
NAT (network address translation) Operation
The process used to convert private addresses to internet-routable addresses is
Which DHCPv4 message will a client send to accept an IPv4 address that is offered by a DHCP server?
broadcast DHCPREQUEST
What is the most important motivating factor for moving to IPv6?
depletion of the IPv4 addresses
If more than one DHCP server is available on the local network, in which order will DHCP messages be sent between a host and a DHCP server?
discover, offer, request, acknowledgment
What protocol is responsible for automatically assigning IP addressing information?
DHCP Dynamic Host Configuration Protocol (DHCP) is responsible for automatically assigning IP addressing information.
A DHCP-enabled client PC has just booted. During which two steps will the client PC use broadcast messages when communicating with a DHCP server? (Choose two.) DHCPDISCOVER DHCPACK DHCPOFFER DHCPNAK DHCPREQUEST
DHCPDISCOVER, DHCPREQUEST
Which two reasons generally make DHCP the preferred method of assigning IP addresses to hosts on large networks?
It eliminates most address configuration errors, It reduces the burden on network support staff
Refer to the exhibit. A user is configuring a PC with the IP settings as displayed, but the operating system will not accept them. What is the problem?
The IP address is not a usable host address.
A DHCP server is used to assign IP addresses dynamically to the hosts on a network. The address pool is configured with 192.168.10.0/24. There are 3 printers on this network that need to use reserved static IP addresses from the pool. How many IP addresses in the pool are left to be assigned to other hosts?
Topic 9.2.0 - If the block of addresses allocated to the pool is 192.168.10.0/24, there are 254 IP addresses to be assigned to hosts on the network. As there are 3 printers which need to have their addresses assigned statically, then there are 251 IP addresses left for assignment.
Which statement is true about DHCP operation?
Topic 9.2.0 - The client broadcasts a DHCPDISCOVER message to identify any available DHCP servers on the network. A DHCP server replies with a DHCPOFFER message. This message offers to the client a lease that contains such information as the IP address and subnet mask to be assigned, the IP address of the DNS server, and the IP address of the default gateway. After the client receives the lease, the received information must be renewed through another DHCPREQUEST message prior to the lease expiration.
Which of the following techniques use native IPv6 connectivity? dual stack tunneling translation all of the above
dual stack
Which is a DHCPv4 address allocation method that assigns IPv4 addresses for a limited lease period?
dynamic allocation
Which two types of devices are typically assigned static IP addresses? (Choose two.) workstations printers web servers hubs laptops
printers, web servers
Who is responsible for statically assigning IP addressing information?
the network admin Although a user can assign IP addressing information, this is most commonly the responsibility of the network administrator.
