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

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

Before you design an ACI fabric, it is important to understand existing application interactions. If you do not understand them entirely, which approach can you use?

A. Design a classic routing configuration in which everybody can talk to anybody as the equivalent to a contract called "anyany" that all EPGs provide and consume.

B. Design around the Cisco ACI whitelist model using the common tenant, where, by default, two EPGs can communicate to each other in the absence of a contract.

C. Map each EPG to familiar constructs such as VLANs that provide segmentation and will apply policy application interactions.

D. Leverage advanced orchestration tools like Cisco Intelligent Automation for Cloud or Cisco UCS Director to document existing application interactions.

You want to satisfy the business, risk, and customer requirements. Which option is a consideration when you select and design an ACI fabric?

A. the requirement for meaningful services (such as traffic load balancing, segmentation, filtering, traffic insertion, and monitoring) for workloads provided by virtual Layer 4 to Layer 7 servers

B. virtual machine mobility because moving from one server to another one would have to occur on the same leaf so that ACI can preserve virtual machine visibility and policy enforcement

C. the breakdown of virtual versus physical workloads because virtual workloads are treated preferentially in ACI

D. the requirement for a central point of management, but no centralized control plane

Which statement about bridge domains is true?

A. EPGs can be associated with multiple bridge domains within a tenant.

B. Subnets may overlap across bridge domains within a tenant.

C. Applications that require Layer 2 flooding should use one bridge domain per subnet.

D. Bridge domains support only private or public subnet scopes.

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 four options are benefits of the Cisco ACI fabric and OpenStack environment? (Choose four.)

E. troubleshooting

F. southbound integration

G. Layer 4 to Layer 7 service integration

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

Which statement about the programming model and APIs available to automate network functions within ACI is true?

C. Every configurable element in ACI is part of the object tree known as the software development kit.

D. You can modify configurations with HTTP DELETE calls and retrieve information with HTTP POST calls.

E. You can perform a CLI-based configuration from your desktop to the controller using cURL.
