Saturday 70-216 Question of the Day

| While Frank is out, I'm kind of filling in. (But no one can really fill Franks' shoes.)
Here is the Q of the Day:
Your company wants to deploy a network consisting of 10 servers and 200 clients. As a Network Administrator, it is your responsibility to plan for the network. You decide to implement a routed network and segment the network in two parts.
Required result: You are required to provide automatic IP address assignment to all client computers for less administrative burden.
Optional result 1: Clients on each segment should be able to get their IP address lease.
Optional result 2: Clients should be able to get IP address in case of DHCP server failure.
Suggested solution: Install DHCP server and configure clients to assign automatic IP address from that server. Install DHCP relay agent on the same server and configure it to take requests from DHCP clients on the segment other than where DHCP server is installed.
Which results does the suggested solution produce?
A.Suggested solution produces the required result and both optional results.
B.Suggested solution produces only the required result.
C.Suggested solution produces the required result and one of the optional results.
D.Suggested solution does not produce the required result.
Good luck! See you tomorrow!  | |

| I'll go with 'D' Required result is not fulfilled. Option 1 is not fulfilled. | |

| i will go with C...
IP address managed to leasee out to 2 routed network but not the Dhcp failed redundancy..
So, 2nd option is out.. | |

| Assuming the required result is not concerned with DHCP going down, then I would choose C since the second optional requirement would not be met. The clients might self configure to an AIPA address if DHCP were down, but the 2 segments would not talk. | |

| I will say D, as having the proxy on the same server means that only one subnet will have addresses. The whole idea of a proxy is to be placed on a subnet that has no dhcp server. | |
| mcdoud 2002-04-13, 3:01 pm |
| I assumed this is a multihomed server serving 2 subnets via 2 adapters. It would need routing enabled (which is not mentioned, so I might be inclined to agree with you on answer D now). | |

| How about D? 
A relay agent must be installed on a server located on the same segment as the clients it is intended to service. In this scenario, the relay agent is to be installed on a different segment from the one the intended clients are located on. | |
| mcdoud 2002-04-13, 9:43 pm |
| Actually I got to thinking about it and if the server were multihomed with an adapter on each subnet, why would it need DHCP relay? Would it not see the requests from both subnets? In any case, we are not told that it is a multihomed machine anyway, so this solution will not work.
So, I agree, answer is D.
(sometimes I tend to go way out in left field, as you may have noticed!) | |

| My answer is C. | |

The answer is:
B
The required result is fulfilled if DHCP service is used. To fulfill the first optional result, it is necessary to install DHCP relay agent on the segment other than on which the server is installed. Thus, the first optional result does not get fulfilled and neither does the second, as nothing has been done for fault tolerance. To fulfill the second optional result, it is necessary to have at least one more DHCP server installed on the network. | |

| I’ll have to go on record as disagreeing with the answer to this one and here’s why. The requirement is to provide address assignment automatically to “all client computers” via DHCP using the least administrative burden possible. While I agree that the DHCP server service greatly simplifies the task of assigning addresses and is the least burdensome administratively, the required result also states address assignment automatically “to all client computers,” which will not occur if the suggested solution is implemented.
In the suggested solution, the DHCP relay agent is to be installed on the same server that the DHCP server service is installed on and configured to service clients on the segment other than where the DHCP server is located. Meaning that if the suggested solution is implemented, the relay agent is to be installed on a different segment from the one the clients it is intended to service is located on. A relay agent must be installed on a server located on the same segment as the clients it is intended to service, as broadcasts do not cross routers and we know that the router is not DHCP/BOOTP enabled because optional result 1 is also incorrect.
Optional result 1 states: “Clients on each segment should be able to get their IP address lease,” and clients on each segment would be able to get their IP address lease automatically from the DHCP server service if the router joining the two segments was DHCP/BOOTP enabled. However, in this case, the router is not and consequently, optional result 1 is also wrong.
Therefore, since the relay agent in the proposed solution is to be installed on a different segment and the router joining the two segments is not DHCP/BOOTP enabled, it is impossible for clients located on the second segment to receive automatic address assignment from the DHCP server service and the required result is, therefore, wrong because “all clients computers,” as stated in the required result, will not receive automatic address assignment via DHCP. | |

| Okay, okay! Poorly worded question!
Give me a break!
(After all, I'm not Frank! ) | |
| Zaraspook 2002-04-14, 1:12 pm |
| LOL....mrfixit, you'll always get a break from me!!! | |
| jakob79 2002-04-14, 10:51 pm |
| what about the scope? there isn't any mention about whether there is a superscope or not..  | |
| mcdoud 2002-04-15, 9:39 am |
| See how controversial/confusing this question was?!!!
Unfortunately, I believe this is the kind of question we can expect to see on the tests! |
