Question 1 Show Refer to the exhibit. Which rule does the DHCP server use when there is an IP address conflict? A. The address is removed from the pool until the conflict is resolved. Answer: A Question 2 How dose a DHCP server dynamically assign IP address to host? A. Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement. Answer: C Question 3 Which two tasks does the Dynamic Host Configuration Protocol perform? (Choose two) A. Set the IP gateway to be used by the network. Answer: C F Question 4 Which statement is correct regarding the operation of DHCP? A. A DHCP client uses a ping to detect address conflicts. Answer: D Explanation An address conflict occurs when two hosts use the same IP address. During address assignment, DHCP checks for conflicts using ping and gratuitous ARP. If a conflict is detected, the address is removed from the pool. The address will not be assigned until the administrator resolves the conflict. (Reference: http://www.cisco.com/en/US/docs/ios/12_1/iproute/configuration/guide/1cddhcp.html) Refer to the exhibit. Using the information shown, answer the question Question 1: All hosts in the networks have been operational for several hours when the DHCP server goes down. What happens to the hosts that have obtained service from the DHCP server? A – The hosts will not be able to communicate with any other hosts. Answer: B Explanation: DHCP often uses dynamic allocation mechanism to save IP addresses, which assigns an IP address to a client for a limited period of time. So when the DHCP server goes down, that client can still use the allocated IP address for a period of time Question 2: What is the purpose of the DHCP server? A – to provide storage for email Answer: D Explanation: The main purpose of the DHCP server is to provide IP configuration parameters to hosts such as the default gateway, domain name, Domain Name System (DNS) server… Question 3: How is the message sent from a PC2 when is first powers on and attempts to contact the DHCP Server? A – Layer 3 unicast Answer: B Explanation: When a client boots up for the first time, it transmits a DHCPDISCOVER message on its local physical subnet. Because the client has no way of knowing the subnet to which it belongs, the DHCPDISCOVER is an all-subnets broadcast (destination IP address of 255.255.255.255, which is a layer 3 broadcast address). The client does not have a configured IP address, so the source IP address of 0.0.0.0 is used. Question 4: What is the default behavior of R1 when PC1 requests service from DHCP server? A – Drop the request Answer: A Explanation: When PC1 requests service from DHCP server (for example, it requests an IP address), it sends a broadcast packet. But R1 router, by default, will not forward broadcast packet and drop it. For your information, if you want to use the DHCP server from another network (like in this case) you can use the ip helper-addresscommand which will make the router forward UDP broadcasts. In the real exam you will be taken to a LAB simulation environment but it is, in fact, just a group of 4 multi-choice questions! How does DHCP server dynamically assign IP address to host?How does a DHCP Server dynamically assign an IP address to a host? Address are permanently assigned so that the host uses the same address at all times. Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.
Which rule does the DHCP server use when there is an IP conflict?During address assignment, DHCP checks for conflicts using ping and gratuitous ARP. If a conflict is detected, the address is removed from the pool. The address will not be assigned until the administrator resolves the conflict.
What is the purpose of DHCP server MCQS?DHCP (dynamic host configuration protocol) provides __________ to the client. Explanation: 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.
What is the purpose of the DHCP server *?A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients.
