DHCP Group of Four Questions
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.
B – The hosts will continue to communicate normally for a period of time.
C – The hosts will be able to communicate with hosts outsides their own network
D – The hosts will only be able to communicate with other hosts by IP address not by hostname
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
B – to translate URLs to IP addresses
C – to translate IPv4 addresses to MAC addresses
D – to provide an IP configuration information to hosts
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
B – Layer 3 broadcast
C – Layer 3 multicast
D – Without any Layer 3 encapsulation
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
B – Broadcast the request to R2 and R3
C – Forward the request to R2
D – Broadcast the request to R2, R3 and ISP
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-address command 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!

Which statement is correct regarding the operation of DHCP?
a…. b… c….
d. if an address conflict is detected, the address is removed from the pool and an administator must resolve the conflict
e. if an address conflict is detected, the address is removed from the pool for an amount of time configurable by the administror
f.d. if an address conflict is detected, the address is removed from the pool and will not be reused until the server is rebooted.
In the dump says the answer is E, but i believe is D. The theory in curriculum doesn’t say anything about a time.
Thank you
Sarf…i am not able to open all the questions. it only has 5 questions when i download…486q
@kevin You have to buy a prgram called VCE(Visual CertExam) Manager.(google it)
hai…..
i cleared my ccna yesterday successfully…..thanks to 9tut.com
Hi 9tut,
Can someone send me the dump of the latest of CCNA 640-842 vce file. @ rain.torres@hotmail.com.. Ill be taking my exam on the last week of September. Hope to get one.. Thanks a lot!
hey rye05

about the dhcp conflict, I think the correct answer is D, as also reported by the cisco web site:
“The server detects conflicts using ping. The client detects conflicts using gratuitous Address Resolution Protocol (ARP). If an address conflict is detected, the address is removed from the pool and the address will not be assigned until an administrator resolves the conflict.”

Bit Confused, answer is different
Respected sir/mad’m (s),
I will be appearing CCNA exam on 12th of this month…………….If you all may kindly pass me on some hints and please……….
Thanking you
@avi
if two or more devices are using the same IP then that IP is removed from the pool. the admin has to /release and /renew the hosts
Thanks “Xallax”
Hi, Appreciate if someone could send me the latest dumps at treepanel.ken@hotmail.com , i plan to take the exams at the end of sep.
Thanks.
While communication between host 1 and host2 over the point-To-Point WAN, which protocol or technology is represented by a dashed line A?
A) IP
B) T1
C) PPP
D) IEEE 802.3
I am bit confused, it should be A) IP some dump had D) IEEE 802.3 because in WAN Ethernet is not used.
@avi
http://www.9tut.net/icnd2/miscellaneous-questions
computers “talk” using IP
Thanx 9tut, i passed my exam withyour help SOUTH AFRICA
Given the HOST A and HOST B are in different networks. When HOST A is trying to communicate with HOST B, which step will HOST A take first?
a) Create an ARP request to get a MAC address for HOST B.
b) Send the data frames to the default gateway.
@avi
MAC is used only locally. option a is ruled out.
Thanks again
@XAVI awesome….
me too plzz… my exam on 23.09.2011.
Folks … stop asking for dumps … the best way to proceed is asking questions … share a problem or two … do not be afraid of asking questions … the worst fear is the fear itself!
Concentrate on the following:
1) Drag and Drop (15%)
2) Subnet (30%)
3) Lab Sim (25%)
4) Rest Of the material (30%)
Sharing is powerful!
@ anyone can u send me the latest CCNA actual exam?
please send it to sab3001@hotmail.com
Appreciate anyone who will share it. Thanks!
