Cisco 300-620 Online Questions & Answers

  • Question 231:

    A Cisco ACI leaf node has received a Layer 2 frame from an unknown endpoint. The bridge domain is configured for Hardware Proxy. Which action will the ACI fabric take on the traffic?

    A. The leaf will flood the traffic to all attached nodes configured with the bridge domain. Attached nodes will respond with a proxy ARP.
    B. The leaf will flood the traffic to all attached nodes configured with the bridge domain. Attached nodes will flood the traffic to endpoints.
    C. The leaf will forward the traffic to a spine. If the spine has no information in the COOP database, the traffic will be dropped.
    D. The leaf will forward the traffic to a spine. If the spine has no information in the COOP database, the traffic will be flooded.

  • Question 232:

    Which new construct must a user create when configuring in-band management?

    A. VLAN pool
    B. management contract
    C. management tenant
    D. bridge domain

  • Question 233:

    An engineer plans a Cisco ACI firmware upgrade. The ACI fabric consists of three Cisco APIC controllers, two spine switches, and four leaf switches. Two leaf switches have 1-Gb copper ports for bare metal servers, and the other two leaf switches have 10-Gb SFP ports to connect storage. Which set of actions accomplishes an upgrade with minimal disruptions?

    A. Upgrade the APIC controllers by selecting the desired firmware and choosing Upgrade Now. Divide the switches into two upgrade groups: spines and leaves. Start the firmware upgrade on the spine upgrade group and then proceed with the leaf upgrade group.
    B. Upgrade the APIC controllers by initiating the upgrade process that uses the most recent uploaded firmware. Divide the switches into three upgrade groups: spines, 1-Gb switches, and 10-Gb switches. Start the firmware upgrade on the spine upgrade group and then proceed with the other two groups.
    C. Upgrade the APIC controllers by selecting the desired firmware and choosing Upgrade Now. Divide the switches into two upgrade groups with one spine, one 1-Gb switch, and one 10-Gb switch per group. Start the firmware upgrade on the first upgrade group and when it finishes, start the second upgrade group.
    D. Upgrade the APIC controllers as a single group by selecting the firmware and choosing Upgrade Now. Divide the switches into four upgrade groups with one switch per group. Start the firmware upgrade on each upgrade group in succession until all four are complete.

  • Question 234:

    Which two settings are available in a Cisco ACI contract? (Choose two.)

    A. version
    B. subject
    C. constraint
    D. policy
    E. scope

  • Question 235:

    An engineer must securely export Cisco APIC configuration snapshots to a secure, offsite location The exported configuration must be transferred using an encrypted tunnel and encoded with a platform-agnostic data format that provides namespace support. Which configuration set must be used?

    A. Policy: Export Policy Protocol: TLS Format: JSON
    B. Policy: Import Policy Protocol: TLS Format: XML
    C. Policy: Import Policy Protocol: SCP Format: JSON
    D. Policy: Export Policy Protocol: SCP Format: XML

  • Question 236:

    What is the result of the pcEnPref flag configured on the epg-App_EPG?

    A. Any configuration changes to the private network are validated.
    B. Access control rules for the L3Out network are applied.
    C. Access control rules for the private network are applied.
    D. Any changes to the underlying EPG objects are forbidden.

  • Question 237:

    An engineer is troubleshooting fabric discovery in a newly deployed Cisco ACI fabric and analyzes this output:

    Which ACI fabric address is assigned to interface lo1023?

    A. VXLAN tunnel endpoint
    B. Physical tunnel endpoint
    C. Fabric tunnel endpoint
    D. Dynamic tunnel endpoint

  • Question 238:

    Refer to the exhibit. An engineer must configure a bridge domain inside the Cisco ACI fabric called BD. The configuration must permit EP2 and EP3 to reach EP1. Which configuration must be applied on the bridge domain to accomplish this goal?

    A. Define the Pervasive gateway on BD.
    B. Enable L2 Unknown unicast flooding.
    C. Optimize L2 Unknown unicast traffic.
    D. Configure unicast routing within BD.

  • Question 239:

    Refer to the exhibit.

    Server A is connected to the Cisco ACI fabric using two teamed interfaces. One interface in a team is configured as active and the other remains in standby mode. When a failover occurs and the standby interface becomes active, it uses its built-in MAC address to send traffic. Which bridge domain configuration must be applied to resolve the issue?

    A. Configure Hardware proxy.
    B. Set L2 Unknown Unicast to Flood.
    C. Enable ARP flooding.
    D. Activate Limit IP Learning to Subnet.

  • Question 240:

    Which feature allows firewall ACLs to be configured automatically when new endpoints are attached to an EPG?

    A. ARP gleaning
    B. dynamic endpoint attach
    C. hardware proxy
    D. network-stitching
