Cisco 300-630 Online Questions & Answers

• Question 1:

  An engineer must implement an L3Out within a tenant to allow the reachability to services outside of the Cisco ACI fabric. The requirement is to allow communication from the EPGs in the same VRF to the external services and save TCAM resource utilization. Which contract insertion method must be used to meet these requirements?

  A. Provider: each service EPGs Consumer: vzAny inside the VRF
  B. Provider: each service EPGs Consumer: L3Out external EPGs
  C. Provider: L3Out external EPGs Consumer: each service EPGs
  D. Provider: L3Out external EPGs Consumer: vzAny inside VRF
  D. Provider: L3Out external EPGs Consumer: vzAny inside VRF

• Question 2:

  Which mechanism is used by ACI spine switches to maintain a consistent copy of the endpoint address and location information?

  A. COOP
  B. ISIS
  C. BD
  D. OSPF
  A. COOP

• Question 3:

  Refer to the exhibit.

  

  New e-commerce software is deployed on Cisco ACI fabric. The environment must meet these requirements:

  The overall number of contracts must be reduced by reusing the existing contracts within a VRF when possible.

  The e-commerce software must communicate only with software EPGs that are part of the same ANP.

  The e-commerce software must be prevented from communicating with applications in different ANPs.

  B. Global
  C. Endpoint Group
  D. Application Profile
  D. Application Profile

• Question 4:

  Refer to the exhibit.

  

  Which method does Cisco ACI fabric use to forward L2 Unknown Unicast packets?

  A. The source leaf sends the traffic to all ports in BD.
  B. Packets are dropped if dMAC is absent in COOP.
  C. The traffic is flooded using VRF Outer Multicast Group ID.
  D. Traffic is flooded to all Layer 2 ports of ACI fabric.
  C. The traffic is flooded using VRF Outer Multicast Group ID.

• Question 5:

  What is a characteristic of a stretched bridge domain solution between Cisco ACI sites with Layer 2 flood enabled?

  A. BUM traffic between sites leverages ISN multicast replication.
  B. The solution reduces control plane overhead.
  C. Spine head-end replication is used to forward BUM traffic between sites.
  D. Contracts are local to the provided site.
  C. Spine head-end replication is used to forward BUM traffic between sites.

• Question 6:

  Refer to the exhibit.

  

  An engineer must allow IP mobility between Site1 and Site2 in a Cisco ACI Multi-Site orchestrator. The design must meet these requirements:

  B. Define a unique bridge domain subnet per site.
  C. Configure STP between Cisco ACI fabrics.
  D. Apply the L2 Stretch feature.
  E. Disable inter-site BUM Traffic.
  D. Apply the L2 Stretch feature.
  E. Disable inter-site BUM Traffic.

• Question 7:

  Refer to the exhibit.

  A. location-based PBR host route advertisement resilient hashing
  B. symmetric PBR location-based PBR resilient hashing
  C. symmetric PBR unidirectional PBR resilient hashing
  D. location-based PBR host route advertisement node tracking
  D. location-based PBR host route advertisement node tracking

• Question 8:

  Which requirement applies to migration from Cisco NX-OS mode to Cisco ACI mode with Cisco Nexus 9000 Series Switches?

  B. A permit-all contract must be used for traffic that flows inside the data center.
  C. Pre-existing FCoE must be removed from the Nexus devices.
  D. A minimum of five Cisco APIC appliances must be used in the data center network.
  C. Pre-existing FCoE must be removed from the Nexus devices.

  A. Bidirectional PIM
  B. PIM dense mode
  C. PIM sparse mode
  D. Source Specific Multicast
  A. Bidirectional PIM
