Which statement about OpenStack and ACI is true?

• A.The Nova ML2 plug-in maps APIs into the ACI policy model.
• B.The Cisco APIC driver communicates northbound using the OpFlex plug-in.
• C.Integration can leverage a Cisco APIC plug-in or a Group Policy plug-in.
• D.The Cisco APIC driver is used in place of an OVS driver to communicate to the virtual machine managers.

If flowlet switching and dynamic flow prioritization are enabled, which two statements about ACI fabric load balancing are true? (Choose two.)

• A.The egress leaf reorders out-of-order packets when flowlet switching is used.
• B.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, ...).
• C.A flowlet is a subset of a TCP/UDP flow that is composed of packets that are part of the same bursts of packets.
• 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.Each flowlet of a TCP/UDP flow is treated with same priority and takes the same path to avoid out-of-order packets.
