QUESTION 9
Which option does the Cisco ACI fabric distributed proxy mapping database map the internal tenant MAC or IP address to?
A. Spine port
B. VxLAN tunnel endpoint address
C. Distinguished name
D. IPv6 address
E. Cisco APIC policy
Answer: B
Explanation:
Forwarding within the fabric is between VTEPs. The mapping of the internal tenant MAC or IP address to a location is performed by the VTEP using a distributed mapping database. After a lookup is done, the VTEP sends the original data packet encapsulated in VXLAN with the Destination Address (DA) of the VTEP on the destination leaf. The packet is then de-encapsulated on the destination leaf and sent down to the receiving host. With this model, we can have a full mesh, loop-free topology without the need to use the spanning-tree protocol to prevent loops.

QUESTION 11
How many VLANs are supported by each Cisco ACI VMM?
A. 16 million
B. 64000
C. 32000
D. 16000
E. 8000
F. 4000
G. 1000
H. 2000
Answer: F
QUESTION 12
What is accomplished when you install a bounce entry in a leaf?
A. Eliminate loops
B. Forward GARP packets
C. Redirect traffic to old VTEP destination
D. Redirect traffic to new VTEP destination
Answer: D
Explanation:
Under a normal migration, when a VM moves due to vMotion onto a leaf that does not have those EPGs and VLANs programmed, the will be deployed immediately. vCenter/ESXI host will send a GARP to ACI, the old leaf will bounce traffic to the new location of the endpoint and traffic/learning will occur. The bounce entry will stick around for a bit (about 5 minutes) and then be removed. The EPGs, VLANs, and Default Gateway will be deployed as soon as the move is detected and there will be little to no downtime (I usually see 0-1 ping loss, most of the time just increased latency).
