VMs on Server-1 and Server-2 are on the same Layer 2 domain within a VCF and are sending traffic to each other.
Referring to the exhibit, which three criteria are used when load-balancing traffic? (Choose three.)
A. EtherType
B. source MAC
C. incoming port ID
D. Layer 4 source port
E. destination IP
Answer: A,B,C
Explanation/Reference:
Reference: http://nextheader.net/2016/10/28/virtual-chassis-fabric-part-ii-control-and-forwarding-plane/ ꢀ Layer 2 load-balancing hashing does not involve Layer 3 or Layer 4 header information.
IE: Layer 2: source MAC, destination MAC, Ethertype, Vlan ID, Incoming Port ID, source member ID

You are implementing a Virtual Chassis using QFX5100s and EX4300s in your data center.
In this scenario, which two statements are correct? (Choose two.)
A. Only 10GbE VCP connections can be used between the QFX5100s and the EX4300s.
B. The QFX5100 devices cannot assume the line card role in the Virtual Chassis.
C. Some hardware capabilities are limited by the capabilities of the EX4300 switches.
D. The EX4300 devices can only assume a line card role in the Virtual Chassis.
Answer: C,D
Explanation/Reference:

Why are SW-3 and SW-4 behaving this way? (Choose two.)
A. By default, EX4300 QSFP+ ports are enabled as VCPs.
B. By default, QFX5100 ports are not enabled as VCPs.
C. By default, EX4300 QSPF+ ports are not enabled as VCPs.
