Cisco 300-620 Online Questions & Answers

• Question 21:

  Refer to the exhibit.

  

  A Cisco ACI fabric displays this fault. Which set of actions modifies the event to be displayed as a warning in the future?

  A. Navigate to the ACI Events tab. Create a new record.
  B. Navigate to the ACI Fault tab. Create a new record.
  C. Navigate to the ACI Events tab. Change the severity level.
  D. Navigate to the ACI Fault tab. Change the severity level.
  C. Navigate to the ACI Events tab. Change the severity level.

  ---

  Explanation/Reference:

  In the Events tab of an APIC GUI component, you can change the severity of a displayed event or you can suppress (squelch) it altogether.

  Step 1: Navigate to the Events tab that currently displays an instance of the event.

  Step 2: Choose one of the following actions:

  To change the severity of these events, right-click the row of the desired event code, select Change Severity, select the desired severity level, and click Change Severity. To prevent these events from appearing in event reports (squelching the event), right-click the row of the desired event code, select Ignore Event, then click Ignore Event.

  With either of these actions, a dialog box appears in which you can confirm the selected action. In both cases, the dialog box displays the path to the Affected Monitoring Policy, which will be automatically modified as a result of the action. To undo the action later, you can navigate to this policy and manually modify it as described in Changing Event Severity or Squelching an Event in the Monitoring Policy.

• Question 22:

  What are two PBR characteristics of the Cisco ACI Active-Active Across Pods deployment mode in Cisco ACI Multi-Pod design? (Choose two.)

  A. Traffic is dynamically redirected to the firewall that owns the connection.
  B. Deployment occurs in transparent mode.
  C. The connection state is unsynchronized.
  D. Deployment occurs in go-to mode only.
  E. This mode causes the traffic to flow asymmetrically.
  A. Traffic is dynamically redirected to the firewall that owns the connection.
  D. Deployment occurs in go-to mode only.

  ---

  Explanation/Reference:

  Active-active firewall cluster stretched across pods: beginning with Cisco ACI Release 3.2(4d), an active/active firewall cluster can be stretched across pods. When deploying Cisco ASA or Cisco Firepower firewall appliances, this deployment model takes the name of “split spanned EtherChannel” and ensures that all the nodes of the cluster “own” the same MAC/IP values so that the stretched firewall cluster appears as a single logical entity to the ACI Multi-Pod fabric. This deployment model removes any concern about the possible creation of asymmetric traffic paths for both east-west and north-south traffic flows, as traffic will be dynamically redirected to the specific firewall node owning the connection state for that specific traffic flow.

• Question 23:

  An engineer is building an L3Out using 802.1Q tagging, with each VLAN mapped to its own IP address on the external connection. Which interface type should be configured?

  A. Layer 3 routed port
  B. Layer 3 floating SVI
  C. Layer 3 routed subinterface
  D. FEX host interface
  C. Layer 3 routed subinterface

  ---

  Explanation

  The correct answer is C because a Layer 3 routed subinterface supports 802.1Q tagging with a separate IP address per VLAN on the external connection. Option A is incorrect because a routed port is not VLAN-tagged. Option B is incorrect because a floating SVI serves a different adjacency model. Option D is incorrect because a FEX host interface is not the correct construct for L3Out VLAN-tagged routing adjacency.

• Question 24:

  Refer to the exhibit.

  

  An engineer must set a policy to reuse the old password when changed after two days. Which action set accomplishes this goal?

  A. Change the password four times. Set the minimum period between changes to 6 hours.
  B. Change the password two times. Set the minimum period between changes to 6 hours.
  C. Change the password four times. Set the minimum period between changes to 48 hours.
  D. Change the password six times. Set the minimum period between changes to 48 hours.
  C. Change the password four times. Set the minimum period between changes to 48 hours.

• Question 25:

  What do Pods use to allow Pod-to-Pod communication in a Cisco ACI Multi-Pod environment?

  A. over Layer 3 directly connected back-to-back spines
  B. over Layer 3 Out connectivity via border leafs
  C. over Layer 3 IPN connectivity via border leafs
  D. over Layer 3 IPN connectivity via spines
  D. over Layer 3 IPN connectivity via spines

• Question 26:

  An engineer wants to filter the System Faults page and view only the active faults that are present in the Cisco ACI fabric. Which two lifecycle stages must be selected for filtering? (Choose two.)

  A. Raised
  B. Retaining
  C. Soaking, Clearing
  D. Raised, Clearing
  E. Soaking
  A. Raised
  E. Soaking

  ---

  Explanation/Reference:

  Raised and Soaking.

  Soaking = initial state of a fault, when problem condition first detected.

  Raised = fault not resolved within soaking interval.

• Question 27:

  An engineer must configure a Cisco ACI bridge domain to prevent flooding from unknown unicast frames. Which action must be configured in Cisco ACI to accomplish this goal?

  A. Set the bridge domain option to Flood in Encapsulation.
  B. Configure Clear Remote MAC Entries in the bridge domain mode.
  C. Set Disable Remote EP Learn in the Fabric Wide Setting Policy.
  D. Configure the bridge domain to operate in optimized mode.
  D. Configure the bridge domain to operate in optimized mode.

• Question 28:

  Which device is the pervasive gateway shown installed on?

  

  A. proxy spine switch
  B. VMM switch
  C. leaf switch
  D. spine switch
  C. leaf switch

• Question 29:

  A Cisco ACI bridge domain and VRF are configured with a default data-plane learning configuration. Which two endpoint attributes are programmed in the leaf switch when receiving traffic? (Choose two.)

  A. Remote MAC, IP
  B. Remote Subnet
  C. Local IP, not MAC
  D. Local MAC, IP
  E. Local Subnet
  F. Remote IP
  D. Local MAC, IP
  F. Remote IP

  ---

  Explanation/Reference:

  The key point is default data-plane learning configuration

• Question 30:

  DRAG DROP

  An engineer must use a Cisco ACI backup process to back up the entire data center fabric configuration.

  Drag and drop the configuration snippets onto the boxes to back up the configuration, including hashed secure properties to the FTP server.

  Not all configuration snippets are used.

  Select and Place:
