E. QoS
Which three options are major components of the Cisco ACI fabric? (Choose three.)
A. spine switches
B. application network profiles
C. leaf switches
D. Application Policy Infrastructure Controller
E. OpenFlow controller
F. Layer 4 to Layer 7 service devices
Which four options are important functions offered by the Cisco APIC? (Choose four.)
A. fault and event management
B. hypervisor, storage, and computing management
C. Layer 3 through 5 services integration
D. statistical collection and analysis
E. performance management
F. nonblocking data plane
G. 1.5:1 oversubscribed ports

Which three statements about the group policy model within ACI are true? (Choose three.)
A. It is an abstracted view of application requirements.
B. Policy is portable.
C. Policy is based on the IP addresses of application services.
D. Policy is extensible.
E. Policy maintains flow information.
F. Policy is enforced from the Cisco APIC.
G. Policy follows the blacklist model.
Which two options are benefits of the ACI fabric beyond forwarding traffic from physical and virtual servers? (Choose two.)
A. zero-touch provisioning of fabric switches
B. centralized control plane
C. decoupling of underlay and overlay
D. applying policy independently of forwarding
E. increased performance due to full-mesh topology
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 statement about designing a migration approach of an existing Data Center network to Cisco ACI is true?
A. The first action is to connect the Cisco APIC to the existing core Layer 3 routers so that the APIC can begin to be involved in traffic forwarding.
B. When migration is complete, the existing Layer 3 devices should still serve as the default gateway.
C. The service nodes must be moved first because Layer 4 to Layer 7 services (FW/LB) in the existing network will not be functional during migration.
D. Simplify the migration by associating every EPG to a VLAN.
Which option is for migrating an existing Data Center network to Cisco ACI?
A. First migrate existing FEXs to 9500.
B. First connect the core (for example, Cisco ASR 9000 Router or Cisco Nexus 7000 Series Switches) to the ACI fabric that supports external connectivity routing mechanisms (OSPF NSSA, iBGP, and static routes).
C. First disable flooding on each bridge domain during migration to avoid broadcast storms.
D. First migrate existing access layer (for example, Catalyst 5500/6000 + FEX) to Cisco MDS 9500 Series.
Which four types of devices can be connected to a leaf device in an ACI fabric? (Choose four.)
A. virtualized servers
B. 10M Ethernet devices
C. Layer 4 to Layer 7 services nodes
D. Layer 2 switch using FabricPath
E. bare metal servers
F. Layer 3 routers
G. another leaf
