600-511 Online Practice Questions and Answers

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.

Which three options are the building blocks of Cisco ACI? (Choose three.)

A. imperative configuration model

B. fabric policy

C. centralized management

D. control-plane isolation

E. automation

F. a RESTful GUI interface for optimal configuration

Which option is an ideal environment in which to deploy ACI?

B. virtual storage farm

C. disaster recovery site

D. enterprise core

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 two statements about server connectivity in ACI are true? (Choose two.)

A. Unicast traffic from servers in the same EPG is not permitted unless a specific contract allows it.

B. Unicast traffic from servers in a different EPG is not permitted unless a specific contract allows it.

C. Unicast traffic from servers in a different EPG is not permitted unless both EPGs are in the same bridge domain.

D. Multicast traffic from servers in the same EPG is not permitted unless a specific contract allows it.

E. Multicast traffic from servers in the different EPG is not permitted unless a specific contract allows it.

F. Multicast traffic from servers in a different EPG is not permitted unless both EPGs are in the same bridge domain.

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

A. You can leverage a custom-built GUI that sends HTTPS calls.

B. Advanced orchestration tools like Cisco Intelligent Automation for Cloud or Cisco UCS Director are available for end-to-end provisioning of compute and network resources using the open OpFlex protocol.

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.

Which three options are the major components of the ACI fabric? (Choose three.)

A. bidirectional optics

B. Application Policy Infrastructure Controller

C. spine switches

D. directory service nodes

E. leaf switches

F. Layer 4 to Layer 7 service devices

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

What is the purpose of the mgmt tenant?
