Which two actions should you perform?

Your network contains an Active Directory domain named contoso.com. The domain
contains two member servers named Server1 and Server2.
You install the DHCP Server server role on Server1 and Server2. You install the IP Address
Management (IPAM) Server feature on Server1.
You notice that you cannot discover Server1 or Server2 in IPAM.
You need to ensure that you can use IPAM to discover the DHCP infrastructure.
Which two actions should you perform? (Each correct answer presents part of the solution.
Choose two.)

Management (IPAM) Server feature on Server1.
You notice that you cannot discover Server1 or Server2 in IPAM.
You need to ensure that you can use IPAM to discover the DHCP infrastructure.
Which two actions should you perform? (Each correct answer presents part of the solution.
Choose two.)

A.
On Server2, create an IPv4 scope.

B.
On Server1, run the Add-IpamServerInventory cmdlet.

C.
On Server2, run the Add-DhcpServerInDc cmdlet

D.
On both Server1 and Server2, run the Add-DhcpServerv4Policy cmdlet.

E.
On Server1, uninstall the DHCP Server server role.

Explanation:
The Add-IpamServerInventory cmdlet adds a new infrastructure server to the IP Address
Management (IPAM) server inventory. Use the fully qualified domain name (FQDN) of the
server to add to the server inventory.
The Add-DhcpServerInDC cmdlet adds the computer running the DHCP server service to
the list of authorized Dynamic Host Configuration Protocol (DHCP) server services in the
Active Directory (AD). A DHCP server service running on a domain joined computer needs
to be authorized in AD so that it can start leasing IP addresses on the network.

I suppose Answer should be C and E ….

Problem: A DHCP server is not discovered.

Solution: Verify that the DHCP server role is not installed on the IPAM server. Verify that at least one IPv4 scope is configured on a DHCP server, and that the IPAM server has a TCP/IP connection to the DHCP server. Also verify that DHCP INFORM request messages sent by IPAM server are not filtered on the network.

premium file C and E?

bigfly

dont think its right A & E because it stated in the question “DHCP role was installed on server 1 & server 2”. which means it wont be able to find any dhcp servers in the network during the discover process…see cbt videos for details

microsoft requirements are as followed:

“An IPAM server is intended as a single-purpose server. It is not recommended to collocate other network infrastructure roles such as DNS or DHCP on the same server. IPAM installation is not supported on a domain controller, and discovery of DHCP servers will be disabled if you install IPAM on a server that is also running the DHCP Server service. The following features and tools are automatically installed when you install IPAM Server.”

The answer is C & E !!!

bigfly

bigfly

Correction I believe Mike is right on with this one Because you need to make server 2 which is running the DHCP has a scope configured.

Also you cannot run IPAM on DNS OR DHCP

A & E ===> final answer

Jake

Jake

You can run an IPAM server on a DHCP server and add it manually (with Add-IpamServerInventory), it’s just that discovery will be unavailable. Since *discovery* was the main objective we must
– uninstall the DHCP server role on Server1 and
– authorize the DHCP server (Server2) in AD.

A and E

IPAM server needs its own space in the server(meaning no DHCP,DNS,DC,RODC to be present).
If you install IPAM on a DHCP server, DHCP will not work.

The question says we MUST have IPAM.
so uninstall DHCP from server1, Put the DHCP on server2 on AD.

BigBob

BigBob

Tested this in my lab – definetly C and E (From IPAM you can discover a DHCP server with no scope configured on it, so not A) -also as the DHCP is on a member server not on a DC then it need to be authorised via PS command.

All agree it is E and C now šŸ™‚

JD

JD

Thanks šŸ™‚

den

so, what is it then with this Microsoft article saying you need at least one IPv4 scope on the DHCP server?
“Verify that at least one IPv4 scope is configured on a DHCP server”
https://technet.microsoft.com/en-us/library/jj878309.aspx#discovery
A could also be an option…

den

den

btw, I also tested in lab: I setup an IPAM and a DHCP server, then ensured the DHCP server was discovered. After successul discovery I deleted the DHCP server from inventory and then deleted the IPv4 scope from this DHCP server and ran discovery again. The server did not appear afterwards! After recreating the scope I ran discovery again and it showed up in the inventory…
so: A, C and E were necessary! :-/

DirkZ

DirkZ

I don’t see why a DHCP server should be authorised in AD, before it can be managed with IPAM.

Therefor I think the answer is E (everybody now agrees on this), then B (not c)

E (to allow discovery)
B (to add DHCP server)

From: https://technet.microsoft.com/en-us/library/dn363341.aspx
Example 1: Add a server to the IPAM server inventory
This command adds a server named Dhcp01.Contoso.com to the IPAM server inventory.
PS C:\> Add-IpamServerInventory -Name Dhcp1.Contoso.com -ServerType DHCP

DirkZ

DirkZ

Or it could be E and C anyway… “IPAM uses Active Directory to locate DHCP servers”
So since answer ‘C’ adds the DHCP to AD…

E and C then…

B&C is correct answer for sure

Its B and E, Question states that you install DHCP on both servers.
Uninstall DHCP and run the Add-IpamServerInventory cmdlet.

You need to uninstall DHCP on server1
Then add server2 to the IPAM inventory (Add-IpamServerInventory -Name Server2.Contoso.com -ServerType DHCP)

Ignore the previous comment,

makes sense that you would have to authorize Server2 before you can add it to IPAM Server Inventory.

Answer is C and E

https://technet.microsoft.com/en-us/library/jj878313.aspx

IPAM discovers DHCP servers that are authorized in the Active Directory domains you specify and that respond to a DHCPInform message.

https://technet.microsoft.com/en-us/library/jj590712%28v=wps.630%29.aspx

Add-DhcpServerInDC
Adds the computer running the DHCP server service to the list of authorized Dynamic Host Configuration Protocol (DHCP) server services in Active Directory (AD).

https://technet.microsoft.com/en-us/library/jj878312.aspx

IPAM must be installed on a domain member computer. You cannot install IPAM on a domain controller. If IPAM is installed on the same server with DHCP, then DHCP server discovery will be disabled.

Scenario:
You have DHCP installed on server1 & 2 (Not configured as far as we have been informed)
You install IPAM on Server1 of those servers
You cannot discover Server 1 or 2 in IPAM console from Server1

Requirement:
You need to ensure that you can use IPAM on Server1 to discover the DHCP infrastructure

Answer: IMO
E: As IPAM cannot run on same server as DHCP uninstall DHCP from Server1
C: As DHCP has not been configured yet (As far as we have been informed) we need to configure it and Authorise it in AD

A: Not a requirement, AS BigBob confirmed in lab
B: DHCP must be Authorised before it can be discovered
D: Nonsense šŸ™‚

So C & E make sense to me

Kevin

Kevin

Confirmation from Technet about answer E:

“IPAM Server must be installed on a domain member computer running Windows ServerĀ® 2012 or a later operating system. The IPAM server is intended as a single purpose server and should not be installed with other network infrastructure roles such as DNS or DHCP. You cannot install IPAM on a domain controller. If IPAM Server is running on a computer that is also running the DHCP Server role, discovery of DHCP servers on the network will be disabled.”

Joe

Joe

C and E…

E is a definite as the comment from Kevin says, if IPAM is installed on a DHCP server you cannot discover DHCP servers.
C is right as you have to authorise a DHCP server before it can be discovered / is classed as a DHCP server)

ā€¢Problem: A DHCP server is not discovered.

ā€¢Solution: Verify that the DHCP server role is not installed on the IPAM server. Verify that at least one IPv4 scope is configured on a DHCP server, and that the IPAM server has a TCP/IP connection to the DHCP server.

from https://technet.microsoft.com/en-us/library/jj878309.aspx

we need to discover the DHCP server as per the question, so based on the quoted information the answer should be A and E surely?

chris

chris

but as per https://technet.microsoft.com/en-GB/library/jj878313.aspx

IPAM discovers DHCP servers that are authorized in the Active Directory domains you specify and that respond to a DHCPInform message.

System_CAPS_importantImportant

If the DHCP server role is installed on the same server with IPAM, DHCP servers will not be discovered on the network.

To discover DHCP servers, the IPAM server reads the DHCP server list stored in the DHCPServers group found in the NetServices container (CN=NetServices,CN=Services,CN=Configuration,DC=domain,DC=com) in Active Directory. If a DHCP server is not discovered, verify that it is found in Active Directory and that the DHCP service is responding to requests.

so I will go with the answer…this is a bad question!!

I think that as mentioned, authorising the server and removing the dhcp role seem the most important factors, so in that case its C and E

den

den

this is quite tricky, as you need to perform 3 steps to get it all properly done:
– authorize DHCP on server2 in AD (because it’s stated we have an AD environment)
– create an IPv4 scope on server 2
– uninstall DHCP role from server1

I think we can assume that the roles are just in a default setup without any further configuration.
If so then you have to authorize server2 and then create the scope on server2 to get at least this one discovered by IPAM. You still have to uninstall DHCP from server1, but if you choose it as answer then you are missing one of the two other aspects needed to get server2 discovered. So you would get nothing done if you choosed the uninstall answer because you have to say good bye to A or C!

My vote therefore: A+C
(I also don’t mind to have server1 not to be discovered as it’s useless anyways…)

Correct answers are C and E.

Add-DhcpServerInDc cmdlet – Adds the computer running the DHCP server service to the list of authorized Dynamic Host
Configuration Protocol (DHCP) server services in Active Directory (AD).

More info : https://technet.microsoft.com/en-us/library/jj590712(v=wps.630).aspx

If the DHCP server role is installed on the same server with IPAM, DHCP servers will not be discovered on the network.

To discover DHCP servers, the IPAM server reads the DHCP server list stored in the DHCPServers group found in the NetServices container
(CN=NetServices,CN=Services,CN=Configuration,DC=domain,DC=com) in Active Directory. If a DHCP server is not discovered, verify that it is
found in Active Directory and that the DHCP service is responding to requests. The following is an example query for DHCP servers that are
authorized in Active Directory for the contoso.com domain. Get-DhcpServerInDC | where-object {$_.dnsname ā€“match ā€œcontoso.comā€}

So you need to uninstall DHCP server role on SERVER1 in order to DHCP servers can be discovered by IPAM on the network.
If you add Server2 to the list of authorized DHCP servers in AD, IPAM will discover it.

I tested this for hours ,you DON’T have to add a dhcp scope for the dhcp server to be discovered,but you DO need to authorize it first,and since most of us agree that dhcp should be uninstalled from server1 (or to not be installed on to begin with)then it leaves us with C&E,but tbh,i actually managed to achieve this with B&C somehow during testing,what i did was to authorize dhcp on server1 & server2,than manually add server1 & server2 with add-ipamserverinventory,but i’m pretty sure that despite me being able to see them both in the ipam inventory IS NOT what microsoft would want in this scenario as it goes against their recommendations,also bear in mind that after you uninstall dhcp from server 1 it will uninstall ipam along with it for some reason,so you will have to re-install ipam again from server manager,i have no idea why,so in conclusion-if i had this question on my exam and i had to choose between B&C or a combo of E and some other option,i would go for E&C just because the B is too vague about what it wants you to achieve (it could be adding server2,server1 or both and does not address the issue of DHCP being installed on the ipam server) A&D seem to be irrelevant,so E – uninstall DHCP from server 1-reinstall it,C-authorize the DHCP server2.
