• Question 53:

  

  Refer to the exhibit. Your application has a reduced health score. Upon inspection, you find a fault that impacts the health score. The fault currently is in soaking state. Which two options are possible next steps while in this state? (Choose two.)

• Question 54:

  What is SD-Access LAN Automation?

  A. LAN Automation configures the fabric overlay using NETCONF and SNMP
  B. LAN Automation configures the fabric overlay using Cisco Plug and Play
  C. LAN Automation configures the fabric underlay using NETCONF and SNMP
  D. LAN Automation configures the fabric underlay using Cisco Plug and Play

• Question 55:

  Which three statements are considered best practice when directly connecting converged network adapters to the fabric? (Choose three.)

  A. Cisco Unified Fabric links must be configured as access ports and FCoE VLAN must not be configured as a native VLAN.
  B. Separate FCoE VLANs must be used for FCoE in SAN-A and SAN-B.
  C. If MSTP is enabled, a separate MST instance must be used for FCoE VlANs.
  D. If the converged access switches (in the same San fabric or in the other) must be connected to each over Ethernet links for the purposes of LAN alternate pathing, then sucj links must explicitly be configured to include all FCoE VLANs. This configuration ensures to extend the scope of the Spanning TreeProtocol for FCoE VLANs to Cisco Unified Fabric and non Cisco Unified Fabric links.
  E. Cisco UF links must be configured as spanning-tree edge ports.
  F. A shared VLAN can be used to carry traffic for each virtual fabric in the SAN (for example, VSAN 1, VSAN 2, and so on).
  B. Separate FCoE VLANs must be used for FCoE in SAN-A and SAN-B.
  C. If MSTP is enabled, a separate MST instance must be used for FCoE VlANs.
  E. Cisco UF links must be configured as spanning-tree edge ports.

  A. It indicates that this subnet is advertised to the external router by the border leaf.
  B. It indicates that this subnet is advertised to the border leaf in ACI fabric.
  C. It indicates that this subnet is advertised to public Internet and must be protected by a firewall.
  D. In indicates that it must be leaked to one or more private networks within ACI fabric
  A. It indicates that this subnet is advertised to the external router by the border leaf.

• Question 60:

  Which option is the best practice recommendation for Spanning Tree configuration in a vPC environment?

  A. Disable PortFast (edge port type) on host-facing interfaces to avoid slow STP convergence.
  B. Disable the BPDU Filter on the edge devices to avoid BPDU propagation.
  C. Disable Rapid PVST or MST on all switches in the Layer 2 domain to avoid slow STP convergence.
  D. Disable the Bridge Assurance feature on vPC links.
