• Question 452:

  An engineer is running an ACI fabric, has VMM integration with VMware vCenter, and wants to enable microsegmentation based on vCenter VM attributes. Which statement about microsegmentation is true?

  A. ACI does not support microsegmentation based on vCenter VM attributes. You should use network attributes for mircosegmentation.

  B. An ACI microsegmented EPG automatically creates a port group with a private VLAN configured on a VMware vCenter distributed virtual switch.

  C. When enabled, microsegmentation performs distributed switching and routing on the ESXi hosts.

  D. Microsegmentation is supported only using AVE or AVS.

  Correct Answer: B

• Question 454:

  APIC EPG Resolution Immediacy is set to "Immediate" Which statement is true about the Deployment Immediacy for VMM domains associated to EPGs?

  A. The "Immediate" and "On demand" options require a port group to be created on the VDS.

  B. If "On demand" is selected, the policy is programmed in the hardware only when the APIC detects a VM created in the EPG.

  C. If "On demand" is selected the policy is programmed in the hardware only when the first packet is received through the data path.

  D. If "immediate" is selected the policy is programmed in the hardware as soon as the leaf is booted.

  Correct Answer: C

  "Deployment Immediacy On demand--Specifies that the policy is programmed in the hardware policy CAM only when the first packet is received through the data path." https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/1-x/aci-fundamentals/b_ACI-Fundamentals/b_ACI-Fundamentals_chapter_01011.html#concept_7A9DDA71E41543258E5B49B58BC5AE4F

• Question 455:

  An engineer is implementing FCoE. Which aspect of DCBXP on a Cisco Nexus switch affects this implementation?

  A. It uses the Cisco Fabric Services protocol to exchange parameters between two peer links.

  B. It always is enabled on 10/100-Mbps native Ethernet ports.

  C. It provides the authentication of peers on the Cisco Nexus switch.

  D. It requires that LLDP transmit and LLDP receive are enabled on the FCoE interface.

  Correct Answer: D

  The Data Center Bridging Exchange Protocol (DCBXP) is an extension of LLDP. It is used to announce, exchange, and negotiate node parameters between peers. DCBXP parameters are packaged into a specific DCBXP TLV. This TLV is designed to provide an acknowledgement to the received LLDP packet. DCBXP is enabled by default, provided LLDP is enabled. DCBXP is disabled on ports where LLDP transmit or receive is disabled.

• Question 457:

  A customer has a requirement to deploy a cloud service and needs to have full control over the underlying OS, data and application. Which cloud model meets this requirement?

  A. PaaS

  B. MaaS

  C. IaaS

  D. SaaS

  Correct Answer: C

  Traditional IT is responsible for Application, Data, Runtime, Middleware, OS, Virtualization, Servers, Storage, Networking. IaaS = Infrastructure as a Service-is responsible for OS, Virtualization, Servers, Storage, Networking. SaaS = Software as a Service-Software deployed by the cloud provider-is responsible for nothing. PaaS = Platform as a Service-Software can be deployed by the customer building their own application | is responsible for Data and Application.

• Question 459:

  A customer has a requirement for an automation solution that supports periodically acquiring configuration from a centralized server and aligning UCS servers to their desired state.

  Which open- source tool meets these requirements?

  A. SaltStack

  B. Terraform

  C. Puppet

  D. Kubemetes

  Correct Answer: C

  "Overview of Puppet architecture: [...] After it receives a catalog, the Puppet agent applies the catalog by checking each resource that the catalog describes. If it finds any resources that are not in their desired state, it makes any changes necessary to correct them."

  https://www.cisco.com/c/dam/en/us/products/collateral/servers-unified-computing/ucs-c-series-rackservers/whitepaper_c11-740103.pdf https://www.cisco.com/c/dam/en/us/products/collateral/servers-unified-computing/ucs-devops-integrationsol-brief.pdf

  from DCCOR book under Puppet section The operation of the Puppet agent involves periodically connecting to the Puppet master, which in turn compiles and sends a configuration manifest to the agent. The agent reconciles this manifest with the current state of the node and updates state that is based on differences.

• Question 460:
