DEBRS Chap 8 v6 (SYC)
DHCP uses UDP port _________ for sending data to the server.
67 is the UDP port number that is used as the destination port of a server. Whereas UDP port number 68 is used by the client.
What is an advantage of configuring a Cisco router as a relay agent? .
It can provide relay services for multiple UDP services.
When a DHCP client receives DHCPOFFER messages, it will send a broadcast DHCPREQUEST message for two purposes.
It indicates to the offering DHCP server that it would like to accept the offer and bind the IP address. It notifies any other responding DHCP servers that their offers are declined.
A router is participating in an OSPFv2 domain. What will always happen if the dead interval expires before the router receives a hello packet from an adjacent DROTHER OSPF router?
OSPF will remove that neighbor from the router link-state database.
Order the steps of configuring a router as a DHCPv4 server.
Step 1- Exclude IP addresses Step 2- Configure a DHCP pool Step 3- Define the default gateway router
What is the result of a network technician issuing the command ip dhcp excluded-address 10.0.15.1 10.0.15.15 on a Cisco router?
The Cisco router will exclude 15 IP addresses from being leased to DHCP clients.
IP assigned for a client by DHCP server is
The IP address offered to a client is only for a limited period of time. There is actually a certain amount of time that the client can use and keep this IP address.
Under which two circumstances would a router usually be configured as a DHCPv4 client?
This is an ISP requirement.T The router is intended to be used as a SOHO gateway.
DHCP (dynamic host configuration protocol) provides __________ to the client.
We use DHCP to allow the hosts to acquire their ip addresses dynamically which is better than visiting each and every host on the network and configure all of this information manually.
The DHCP server _________
Whenever a DHCP server gets a request from a client it responds with a DHCP offer containing IP address being offered, network mask offered, the amount of time that the client can use and keep it, the ip address of the DHCP server making this offer.
Which address does a DHCPv4 server target when sending a DHCPOFFER message to a client that makes an address request?
client hardware address
An administrator issues the commands: Router(config)# interface g0/1Router(config-if)# ip address dhcpWhat is the administrator trying to achieve?
configuring the router to obtain IP parameters from a DHCPv4 server.
Which is a DHCPv4 address allocation method that assigns IPv4 addresses for a limited lease period?
dynamic allocation
What is used in the EUI-64 process to create an IPv6 interface ID on an IPv6 enabled interface?
the MAC address of the IPv6 enabled interface.
broadcast DHCPREQUEST
Which DHCPv4 message will a client send to accept an IPv4 address that is offered by a DHCP server?
