D) service profile
3. If flowlet switching and dynamic flow prioritization are enabled, which two statements about ACI fabric load balancing are true? (Choose two.)
A) Each flowlet of a TCP/UDP flow is treated with same priority and takes the same path to avoid out-of-order packets.
B) A flowlet is a subset of a TCP/UDP flow that is composed of packets that are part of the same bursts of packets.
C) A flowlet is a subset of a TCP/UDP flow that is composed of packets of approximately the same size (64 bytes to 127 is flowlet 1, 128 to 255 is flowlet 2, ...).
D) The first few identified flowlets of a TCP/UDP flow are treated with a higher priority than the last flowlet of the same TCP/UDP flow.
E) The egress leaf reorders out-of-order packets when flowlet switching is used.

A) Security services are provided by the fabric, without the need for external appliances.
B) ACI provides a stateless whitelist approach for all traffic in the fabric.
C) ACI allows for easy integration of external stateful physical and virtual security devices into the fabric.
D) ACI depends on external appliances and software to provide security.
5. Which method does ACI fabric dynamic load balancing use to provide optimal balancing of flows across the fabric?
A) Flows are dynamically allocated according to link BER.
B) Flows are dynamically allocated according to hop-by-hop congestion in the fabric.
C) Flows are dynamically allocated according to congestion at the leaf.
D) Flows are distributed in per packet round-robin.
