How many reservations should you identify?

You have a server named Server 1 that runs Windows Server 2012. SERVER1 has five network adapters.
Three of the network adapters are connected to a network named LAN1.
The two other network adapters are connected to a network named LAN2.
You create a network adapter team named Team1 from two of the adapters connected to LAN1.
You create a network adapter team named Team2 from the two adapters connected to LAN2.
A company policy states that all server IP addresses must be assigned by using a reserved address in DHCP.
You need to identify how many DHCP reservations youmust create for SERVER1.

Explanation:
3 adapter on LAN 1
2 adapters on LAN 2
2 adapters on LAN 1 used in a team, so that’s 3 – 2leaving 1.
2 adapaters on LAN 2 used in a team, so that’s 2 – 2 leaving 0.
1 team on LAN 1 + 1 team on LAN 2 + remaining adapter on LAN 1 = 3.

My suggestion is that the answer is 5

This is an interesting scenario as the company policy requirements states that each server IP address must be assigned via a reservation in DHCP

Recall that reservations in DHCP are based on mac address

Each NIC in the team will require an IP address assigned from a DHCP reservation in order for the NIC team to work.

This is due to the fact that when you create the team, the Virtual NIC for the team will assume the mac address of either one of the physical cards depending on their state.
The Virtual NIC will have a TCP/IP stack assigned to it and the team members will be configured automagically with only the MS Network Adapter Multiplexer Protocol

The virtual NIC for the team will retrieve an IP address from the reservations based on the current mac address assigned to it (which will be a mac address from one of the physical NICs), therefore there is no requirement for a reservation for the Virtual NIC making the team but there is a requirement for a reservation for each physical NIC.

As there are 5 physical NICs in this setup there will be 5 reservations.

I discovered this info by setting it up and investigating in a lab if anyone can find any links to info that proves/disproves my argument please post

I think the question is not interested in that. As always, classroom knowledge is not what happens in real world.

I agree with 3, two sets of teams with an IP addr each = 2 plus you left one int out of the teams so it would need an IP as well.

Am I reading this wrong?

LAN1 in my eyes would mean 3 net adapters that are on the same subnet (take 10.10.1.0/24 for example)
LAN2 – two net adapters that are on the same subnet (10.10.2.0/24)

If I create a team out of LAN 1 and configure a scope to offer leases for 10.10.1.0/24 why would I need another scope for the remaining adapter? Wouldn’t it be included in the scope created for TEAM1 already since it’s the same subnet?

That would mean A is correct.

Can someone please explain? Thanks

@kyo:

5 – (2*1) – (2*1) = 1 Adapter not in a team
1 + 1(teamLan1) + 1(teamLan2) = 3
