Which ACI construct provides the policy-based definition that comprises the communication, performance, and security needs of an application?

A. service profile

B. endpoint group

C. application service profile

D. application network profile

The use of the Cisco Bi-Di 40G transceiver provides cost effective transition to a 40G ACI fabric through transmission over which cabling plant?

A. Category 6a copper

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 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

H. BGP and OSPF routing protocol support

In which two ways are EPGs defined? (Choose two.)

A. static binding with a port

B. host MAC address

C. external routing adjacency

D. based on NetFlow groups

E. using WFQ

When building a contract, what is the function of a filter?

A. classification of traffic

B. a Layer 7 parameter setting for filtering application calls

C. to drop or adjust routing updates

D. to enforce SLAs

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

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 statement about the infrastructure requirements for an ACI fabric is true?

A. Hypervisors that connect to the ACI fabric must support the Cisco Discovery Protocol so that ACI can discover the presence of virtualized hosts and deploy policies to the ports on which a virtualized host is present.

B. The Cisco Nexus 9336PQ form factor is well suited for large enterprise ACI deployments because it provides 288 40 Gigabit Ethernet ports at the spine.

C. Leaf and spine switches can connect at 40 Gbps with multimode fiber by using the Cisco 40 Gbps short-reach bidirectional QSFP optics modules, which do not require new cabling.

D. The Cisco ACI fabric uses an overlay, based on MPLS VPN, to virtualize the physical infrastructure. This overlay maps the tenant endpoint addresses to the location of the endpoint using the tunnel endpoint.
