Which three options are attributes of an ACI fabric? (Choose three.)

A. It is built on a spine-leaf architecture.

B. It uses FabricPath to enable the overlay architecture.

C. It supports external network devices that are connected to the ACI baby spines.

D. It encapsulates every packet that traverses the fabric using VXLAN.

E. It integrates with existing networks through standards-based Layer 2 and Layer 3 protocols.

F. Leaf switches manage the forwarding tables.

G. Spine switches manage the policy enforcement.

Which statement about OpenStack and ACI is true?

A. Integration can leverage a Cisco APIC plug-in or a Group Policy plug-in.

B. The Nova ML2 plug-in maps APIs into the ACI policy model.

C. The Cisco APIC driver communicates northbound using the OpFlex 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. A flowlet is a subset of a TCP/UDP flow that is composed of packets that are part of the same bursts of packets.

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. 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.

D. Each flowlet of a TCP/UDP flow is treated with same priority and takes the same path to avoid out-oforder packets.

E. The egress leaf reorders out-of-order packets when flowlet switching is used.

Which type of ACI switch provides Layer 3 connections to outside networks?

A. border leaf devices

B. leaf devices

C. spine devices

D. service leaf devices

Which two options are components of a device package? (Choose two.)

A. device configuration
