Cisco 600-511 Online Questions & Answers

• Question 1:

  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.
  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).

• Question 3:

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

  B. Application Policy Infrastructure Controller
  C. spine switches
  D. directory service nodes
  E. leaf switches
  F. Layer 4 to Layer 7 service devices
  B. Application Policy Infrastructure Controller
  C. spine switches
  E. leaf switches

• Question 4:

  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
  G. best suited for integration into an access/aggregation/core topology
  A. linear scalability
  B. robust multipathing
  D. deterministic latency

• Question 5:

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

• Question 6:

  Which statement about OpenStack and ACI is true?

  A. Integration can leverage a Cisco APIC plug-in or a Group Policy plug-in.
  B. The Nova ML2 plug-in maps APIs into the ACI policy model.
  C. The Cisco APIC driver communicates northbound using the OpFlex plug-in.
  D. The Cisco APIC driver is used in place of an OVS driver to communicate to the virtual machine managers.
  A. Integration can leverage a Cisco APIC plug-in or a Group Policy plug-in.

• Question 7:

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

• Question 8:

  Which three features or protocols can be used to integrate ACI into existing management tools? (Choose three.)

  A. SNMP
  B. RESTful APIs
  C. Syslog
  D. OSPF
  E. CallHome
  F. BGP
  G. RSPAN
  A. SNMP
  B. RESTful APIs
  C. Syslog

• Question 9:

  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.
  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.

• Question 10:

  Which description of OpFlex is true?

  A. a proprietary protocol that is used for communication between ACI spine and leaf switches
  B. a Cisco protocol that is used between third-party orchestration tools and Cisco APIC
  C. an open and extensible policy protocol for transferring policy between a network policy controller and any device
  D. an open protocol that is used between virtual machine managers and ACI leaf switches to transfer VXLAN-encapsulated packets
  C. an open and extensible policy protocol for transferring policy between a network policy controller and any device
