B. single pair of OM3/OM4 MM fiber

C. single pair of SM fiber

D. Twinax copper

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 congestion at the leaf.

B. Flows are dynamically allocated according to hop-by-hop congestion in the fabric.

C. Flows are dynamically allocated according to link BER.

D. Flows are distributed in per packet round-robin.

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

For which ACI constructs are health scores calculated?

A. bridge domains

B. service graphs

C. contracts

D. filters

E. service device clusters

Which three elements of the ACI fabric contribute to zero-touch deployment capability? (Choose three.)

A. centralized controller for policy, bootstrap, and image management

B. topology auto discovery, automated configuration, and infrastructure addressing

C. loose wiring validation

D. support for iBGP confederations

E. NX-API and NETCONF protocol interfaces

F. orchestration using Visore

Which three options are the primary benefits of a leaf-spine architecture? (Choose three.)

A. linear scalability

B. robust multipathing

C. use of Rapid PVST

D. deterministic latency

E. increased scalability of the proxy database

F. 1.5:1 oversubscribed ports

Which statement about the role of a spine switch is true?

A. It connects leaf devices.

B. It connects spine devices

C. It connects Cisco APICs.

D. It connects hosts.

E. It connects external routers.

F. It connects service nodes.

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 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 two options are two intended uses of Layer 3-External in the ACI fabric? (Choose two.)

A. to provide connectivity to external networks

B. to advertise a default gateway into the ACI fabric

C. to define the default gateway for the devices connected to the ACI fabric

D. to advertise IP and MAC information outside of the ACI fabric

E. to apply policy to endpoints not contained in an EPG
