• Question 162:

  Refer to the exhibit.

  

  An engineer configures the Cisco ACI fabric for VMM integration with ESXi servers that are to be connected to the ACI leaves. The server team requires the network switches to initiate the LACP negotiation as opposed to the servers. The LAG group consists of two 10 Gigabit Ethernet links. The server learn also wants to evenly distribute traffic across all available links. Which two enhanced LAG policies meet these requirements? (Choose two.)

  A. LACP Mode: LACP Standby

  B. LB Mode: Destination IP Address and TCP/UDP Port

  C. LB Mode: Source and Destination MAC Address

  D. LB Mode: Source IP Address and TCP/UDP Port

  E. LACP Mode: LACP Active

  Correct Answer: CE

• Question 164:

  In the context of VMM, which protocol between ACI leaf and compute hosts ensures that the policies are pushed to the leaf switches for immediate and on demand resolution immediacy?

  A. VXLAN

  B. LLDP

  C. IS-IS

  D. STP

  Correct Answer: B

  Immediate—Specifies that EPG policies (including contracts and filters) are downloaded to the associated leaf switch software upon ESXi host attachment to a DVS. LLDP or OpFlex permissions are used to resolve the VM controller to leaf

  node attachments.

  The policy will be downloaded to leaf when you add host to the VMM switch. CDP/LLDP neighborship from host to leaf is required.

  On Demand—Specifies that a policy (for example, VLAN, VXLAN bindings, contracts, or filters) is pushed to the leaf node only when an ESXi host is attached to a DVS and a VM is placed in the port group (EPG).

  The policy will be downloaded to leaf when host is added to VMM switch and virtual machine needs to be placed into port group (EPG). CDP/LLDP neighborship from host to leaf is required.

  With both immediate and on demand, if host and leaf lose LLDP/CDP neighborship the policies are removed.

• Question 165:

  An engineer has set the VMM resolution immediacy to pre-provision in a Cisco ACI environment. No Cisco Discovery Protocol neighborship has been formed between the hypervisors and the ACI fabric leaf nodes.

  How does this affect the download policies to the leaf switches?

  A. No policies are downloaded because LLDP is the only supported discovery protocol.

  B. Policies are downloaded when the hypervisor host is connected to the VMM VDS.

  C. Policies are downloaded to the ACI leaf switch regardless of Cisco Discovery Protocol neighborship.

  D. No policies are downloaded because there is no discovery protocol neighborship.

  Correct Answer: C

  Pre-provision—Specifies that a policy (for example, VLAN, VXLAN binding, contracts, or filters) is downloaded to a leaf switch even before a VM controller is attached to the virtual switch (for example, VMware VDS). This pre-provisions the configuration on the switch.

• Question 166:

  When configuring Cisco ACI VMM domain integration with VMware vCenter, which object is created in vCenter?

  A. datacenter

  B. VMware vSphere Standard vSwitch

  C. VMware vSphere Distributed Switch

  D. cluster

  Correct Answer: C

  Creating a vCenter Domain Profile Using the Basic GUI Before You Begin Before you create a VMM domain profile, you must establish connectivity to external network using in-band management network on the APIC. Procedure Step 1 Login to the Basic Mode in the APIC GUI. Step 2 On the menu bar, choose VM NETWORKING > Inventory. Step 3 In the Navigation pane, right-click VMware and click Create vCenter Domain. Step 4 In the Create vCenter Domain dialog box, in the Virtual Switch Name field, enter a Name. Step 5 In the Virtual Switch field, verify that VMware vSphere Distributed Switch is selected https://www.cisco.com/c/dam/m/en_us/solutions/data-center-virtualization/application-centric-infrastructure/aci-virtualization-guide-chapter.pdf

• Question 167:

  Refer to the exhibit.

  

  An engineer is integrating a VMware vCenter with Cisco ACI VMM domain configuration. ACI creates port-group names with the format of "Tenant | Application | EPG". Which configuration option is used to generate port groups with names formatted as "Tenant=Application=EPG"?

  A. enable tag collection

  B. security domains

  C. delimiter

  D. virtual switch name

  Correct Answer: C

  Step 8 Configuring the delimiter during VMM domain creation, perform the following actions:

  On the menu bar, choose VM NETWORKING > Inventory

  In the Navigation pane, right-click VMware and click Create vCenter Domain.

  In the Create vCenter Domain dialog box, enter a Name.

  Optional: In the Delimiter field, enter one of the following: |, ~, !, @, ^, +, or =. If you do not enter a symbol, the system default | delimiter will appear in the VMware PortGroup name.

• Question 168:

  Refer to the exhibit.

• Question 169:

  What are two descriptions of ACI Multi-Site? (Choose two.)

  A. Routers in the Inter-Site network must run OSPF, DHCP relay, and MP-BGP

  B. ACI Multi-Site is a solution that allows one APIC cluster to manage multiple ACI sites

  C. The Multi-Site orchestrator must be directly attached to one ACI leaf

  D. ACI Multi-Site is a solution that supports a dedicated APIC cluster per site

  E. The Inter-Site network routers should run OSPF to establish peering with the spines

  Correct Answer: DE

• Question 170:

  What is MP-BGP used for in Cisco ACI fabric?

  A. MP-BGP VPNv4 AF is used as protocol on L3Out between a border leaf and an external router

  B. MP-BGP Layer 2 VPN EVPN AF is used to propagate L3Out routes that are received from a border leaf

  C. MP-BGP VPNv4 AF is used to propagate L3Out routes that are received from a border leaf to the fabric

  D. MP-BGP VPNv4 AF is used between spines in an ACI Multi-Pod fabric to propagate the endpoint
