Thu 70-216 Question of the Day

|  As there was slight confusion on Q45 http://www.examnotes.net/forums/sho...&threadid=32319 I thought I would make today's question a slight variation of Q45:
Q47. Yo are the network administrator for your company's Windows 2000 network. Your network consists of three subnets, which contain Windows 2000 Server computers and Windows 2000 Professional computers. A DNS server exists on Subnet1.
You decide to deploy DHCP on a Windows 2000 Server computer on Subnet1. Your routers do not forward BOOTP messages.
You must accomplish the following goals:
1. All clients must use the DHCP server on Subnet1.
2. The DHCP server must not lease IP addresses that are already in use by Windows 2000 Server computers.
3. DHCP clients must automatically create their own A (host) resource records in DNS.
4. The DHCP server must automatically create DHCP clients' PTR resource records in DNS.
5. The DHCP server must configure each DHCP client computer with the IP address of the appropriate default gateway.
6. The DHCP server must configure each DHCP client computer with the IP address of the DNS server.
You take the following actions:
1. On the DHCP server, you configure 3 scopes, one for each subnet.
2. In each scope, you exclude the IP addresses of all Windows 2000 Server computers on that particular subnet.
3. You configure the 003 Router option and the 006 DNS Servers option on the scope level.
4. You configure all Windows 2000 Professional computers to automatically receive their IP configuration dynamically.
5. You configure DNS to accept dynamic updates.
6. You configure the DHCP server to automatically update DNS according to the client requests.
7. You authorize the DHCP server in Active Directory and activate the scopes.
Which goal or goals are accomplished with these actions? (Choose all that apply)
A. All clients use the DHCP server on Subnet1.
B. The DHCP server does not lease IP addresses that are already in use by Windows 2000 Server computers.
C. Each DHCP client automatically creates its own A (host) resource records in DNS.
D. The DHCP server automatically creates each DHCP client's PTR resource records in DNS.
E. The DHCP server configures each DHCP client computer with the IP address of the appropriate default gateway.
F. The DHCP server configures each DHCP client computer with the IP address of the DNS server.
Good Luck .... see you tomorrow for the answer!! | |

| My answer is A,B,C,D,E,F | |
| jeff_j_black 2002-03-14, 12:55 pm |
| 'B,C,D,E,F' | |
| datrupope 2002-03-14, 3:42 pm |
| B,C,
A - Incorrect - Non bootP enabled router.
D - Win2k clients do this automatically, by default, thus the DHCP server doesn't need to.
E F - correct for subnet 1, not 2 and 3 tho | |
| jeff_j_black 2002-03-14, 4:15 pm |
| The trick to this question is the phrase "DHCP client". | |
| Zaraspook 2002-03-14, 7:06 pm |
| How about B, C, D, E, & f?  | |
| KScheler 2002-03-14, 8:24 pm |
| I believe it is B.
Since the router does not forward BOOTP, only clients from the DHCP server's subnet will receive IP configurations. The other answers state that "each" client will do this or that, which is not possible without a DHCP relay agent. | |
| jeff_j_black 2002-03-14, 8:41 pm |
| A - wrong, most would agree, there is no proxy's.
B - right, most would agree.
here's where my point comes in:
C, D, E, F all explicitly state DHCP client does blah blah, or DHCP client gets blah blah. My point is that a client would not be a DHCP client unless it could reach the DCHP server, meaning the clients that are on the same subnet as the DHCP server.
What do you all think? | |
| Zaraspook 2002-03-14, 8:52 pm |
| Agree 100% with Jeff's post above, and that's what makes the 216 so fun and challenging. | |
| KScheler 2002-03-14, 8:58 pm |
| I agree with you, Jeff. That's why I only chose B. No DHCP Relay agents mentioned. | |
| jeff_j_black 2002-03-14, 9:02 pm |
| Yeah, you gotta love this, I can see where people get addicted to certs! Or was that breath mints? | |
| jp_d55 2002-03-15, 12:17 am |
| b,c,d,e,f.
Thats what my logic tells me!!!
A is wrong cause there are no relay agents configured to forward request across routers.
Im not sure about D, is it the Dns or Dhcp which creates (ptr)rr's for the client? | |

And the Answer is ....
Correct Answers: B, C, D, E and F
Your network consists of three subnets that contain Windows 2000 Server and Windows 2000 Professional computers. One DNS server exists on Subnet1. You are setting up a DHCP server on Subnet1.
You create separate scopes for each subnet. As configured, the routers in this scenario will not forward DHCP requests to Subnet1. Only those clients on Subnet1 will be able to retrieve DHCP information. The clients on Subnet2 and Subnet3 will not be able to use the DHCP server on Subnet1 until the Subnet2 and Subnet3 routers are BOOTP-enabled or until a DHCP relay agent is installed on each subnet.
You exclude all addresses from each scope that are used by Windows 2000 Server computers. This will prevent these addresses from being leased to DHCP clients. Therefore, the DHCP server will not lease IP addresses that are already in use by Windows 2000 Server computers.
The default setting with Windows 2000 computers is for the clients to update their A (host) resource records in DNS. Earlier versions of Windows DHCP clients do not support the DNS dynamic update process directly and would need the DHCP server configured properly to update their records. Since only Windows 2000 computers exist, the DHCP clients will update their own A (host) resource records in DNS.
By configuring the DHCP server to automatically update DNS according to the DHCP client requests, you enable the DHCP server to update the DHCP clients' PTR resource records.
By setting the 003 Router and 006 DNS Servers option at the scope level, you ensure that each DHCP client will recieve the correct IP address of the default gateway and the DNS servers. | |

| I still disagree with the question and go with B. As the answers are worded, they seem to imply that ALL clients (A. Says All, C,D,E,& F say Each) are getting IP configuration information from the DHCP server which would not happen without DHCP relay agents or enabling BOOTP on the routers, therefore only clients on subnet1 will receive IP configuration information. Just my humble opinion...................... | |
| jeff_j_black 2002-03-15, 4:19 pm |
| 'C,E,D & F' All say 'each DHCP client' not 'each client'. 'Each DHCP client' points to clients that can reach the DHCP server. So the clients on the same subnet as the DHCP server become DHCP clients, because they are on the same subnet.
There's questions about stuff I don't know about, there's questions about stuff I don't understand, there's questions about stuff I've forgotten, those I'll accept getting wrong. I make it my solemn vow not to miss a question based on semantics. | |
| datrupope 2002-03-15, 4:40 pm |
| I understand that the exams should be hard, as most of us will be dealing with this later on in the real world and they make sure we know what where doing. But do they need to get this nit-picky? The way the question was worded, it still seems like the "each client" choices were refering to clients that were supposed to be DHCP clients, not just ones that actually were. | |
| jeff_j_black 2002-03-15, 5:35 pm |
| I think that this particular question is a bit of an exageration of the semantic type of question. But the exam does have to probe particular concepts in a way that demonstrates your under standing of the concept. You have to use a little critical thinking, beyond just knowing an answer, to get past the 216 and 217. I think that they have really started to give us our money's worth with some of the newer exams. | |
| KScheler 2002-03-15, 9:36 pm |
| Jeff:
After re-reading the question and reading your explaination, I retract my answer and agree with your reasoning.
I've watched these forums for a while before I started getting involved. I like the input from all you guys. It helps the learning process.
Thanks | |
| jeff_j_black 2002-03-15, 10:38 pm |
| Hey, I'm sure that everyones' glad you're here. Whatever you got to say is important too, right? | |
| KScheler 2002-03-16, 11:32 am |
| Thanks Jeff.
Even though I teach some of this stuff as an instructor at a technical college plus help maintain our department's W2k network that consists of 2 W2k domains (1 for faculty, 1 for students). We have about 50 faculty/staff and 21 labs with 21 computers each for our 700+ students, Exchange2000, SQL2000, and Terminal Services running in Application Mode. As you can see, I do get some exposure to the products plus I am fortunate to be able to setup most anything I need in my lab. Even so, I still struggle with test taking, esp. the way MS words their questions. I catch myself looking at the Qs and saying, "But why? or Not in the REAL world."
Later,
KS |
