NO, its not possible to have same MAC addresses for two different network cards. because MAC address is a unique part of the recognition of the network card and it is also called as PHYSICAL address of your PC.
There is possibility of 2 network cards with same MAC address by 3rd party MAC spoofing techniques.........

What are the advantages of MAC Address Filtering?
MAC filtering takes network security to the next level by only granting access to specific network cards.A MAC (media access control) address is a unique identifier for a network card; no two cards have the same MAC address, so it functions like a fingerprint - even a wireless card and an Ethernet card built-in to the same laptop won't have the same MAC address. Therefore, MAC address filtering adds security by only allowing network cards with the right "fingerprint" to access the network.However, it should be noted that MAC address filtering is not a strong form of security. MAC addresses are extremely easy to "spoof" - that is, it's easy to fake the address of a legitimate network card. If an attacker is able to identify the MAC address of a permitted network card, they can masquerade as the legit card. Therefore, MAC address filtering is not a replacement for using encryption. MAC address filtering can help security if used in an environment running WPA.
What happens if two stations are accidentally assigned the same hardware address?
One of them or both would not get an ip address. If on of the computers has Linux and another one has windows (any), Linux system will receive an ip address, and windows will not. If both are Linux most likely you will see the message about conflicting ip addresses (the same for two win xp or any same OSes). Usually server OSes win when compiting for the same ip address (same hardware address gets the same ip address). here hardware address means physical or the MAC address as the hardware addresss of three kinds 1):- static , 2):- dynamic ,3):- configurable in case of the static it is impossible while in case of the others two there is a chance of conflict and both stations may not take part in the in the communication due to conflict
Which two statements describe the operation of an access layer ethernet switch choose two?
The source MAC address within a frame is used by the switch to associate a port with that MAC address. Frames are directed by the switch from one port to another based on the destination MAC address within the frame.
Why a computer might have more than one MAC Address?
The best way to understand a mac address is like a house. If you add another networking device then you have another different mac address for it. Maybe like a neighbors house, just the other house is still on your street. The IP address is like an apartment meaning 1 MAC address and several IP addresses(apartment a, b c and so on). To have one networking device and more than one mac address would mean that virtual networking has been added and a quick system restore to the point prior to the date the new project started will return all configurations to normal, except there may be a few adjusments. A computer might have more than one MAC address, if two or more NIC are installed, for example one wired and one wireless Ethernet card.
Why should you go for two addresses MAC and IP address instead of using one in computer networks?
An IP address has a consistent and predictable route for traffic coming from the internet. A MAC address is not routable.
Can two computers use the same ip address to send emails?
We can have same ip address on two or more computers in the SAME network; both working simultaneously. They should be in same collission domain. Let their MAC address be same first & then assign them same ip address. You can do so by using a network hub. Watch my associated video on www.metacafe.com/channels/austinium2002/
Can computers have the same MAC address on a server?
No, they can't have the same mac address, because mac address is an id for a machine therefore the ip addresses are registered to the DHCP table accordingly to the mac address. So if you spoof the mac address lets say having two machines with the same mac address what will happen is that only one machine at time would be allowed once it disconnect then the other can connect. Why spoofing a mac address? I guess one of the reasons is to defeat a network administrator when they secure their network by filtering the mac addresses so by spoofing the mac address you will be able to access the internet.
What is the drawback of using a MAC address?
Someone can spoof it using a MAC spoof attack. This is where an attack acquires your MAC address, sends a disconnect signal to your computer to disconnect you from the network, and then connects onto the network with your MAC address, making the network's authentication systems think it is you, but it is really a hacker. When you try to get back on, you find that you can't because the network won't allow two computers with the same MAC address to be connected on the network.
Why must NIC not share the same MAC address?
No two cards ever manufactured should share the same address. If two cards contained identical MAC addresses problems would be encountered with network communications.
What happen if i assign a single IP address to two computers which are on network.now if third computer wants to access on computer with that IP address what happens?
No two computers may have the same IP address. This will cause both systems to crash.
When a host is communicating with multiple applications on the same server at the same time which two values will likely be the same in all packets for each session?
IP address MAC address
What happen if two computers have same ip address?
windows will flash up and tell you there is a conflict
What address do layer two switches use?
A MAC address
Can you assign two mac address for a single system?
no we cant have two mac unless we have two nic's
What happens if two computers of the same IP address to the same network?
It is not possible, because there will an error that is call ip conflict error.
How do you sync a music library on two different computers If you have a PC and a Mac the music is on the Mac and I want to sync the music to my PC so I can burn a CD?
Put iTunes on the PC. Use the same iTunes account that is on the Mac.
