Which technology relies on STP as a failsafe mechanism?

  • A. FabricPath
  • B. MPLS
  • C. VXLAN
  • D. vPC


Answer : D

Explanation:
vPC technology allows to build a loop free topology by levering port-channel from access device to vPC domain. A port-channel is seen as a logical link from STP standpoint so vPC domain with vPC-attached access device globally form a star topology at L2 (there is no STP blocked ports in this type of topology). For that case, STP is used as a fail-safe mechanism to protect any network loop caused by human error (like plugging a loopback cable across the 2 vPC peer device).

Switch(config)# login block-for 60 attempts 10 within 180
Switch(config)# login quiet-mode access-class acl
Refer to the exhibit. Which statement is true about the impact to login requests on a Cisco NX-OS switch that uses this configuration?

  • A. Hosts in the ACL are denied after 10 failed login attempts occur within 180 seconds.
  • B. Hosts outside the ACL are allowed if more than 10 failed login attempts occur.
  • C. Hosts in the ACL are allowed after 10 failed login attempts occur within 180 seconds.
  • D. All hosts are denied if 10 failed login attempts from hosts in the ACL occur in 180 seconds.


Answer : C

Explanation:
The ג€login quiet-mode access-class acl ג€command can help authorized users to log into device in case of system login block-for function. Then users from the acl localization can log into the cisco device even when others cannot.

Refer to the exhibit. You have a suboptimal outbound routing issue in the data center.
Which two options can you use to resolve the issue? (Choose two.)

  • A. On the OTV edge devices, configure a VACL that prevents FHRP hellos from being forwarded on the overlay.
  • B. On the OTV VDC, configure an OTV MAC route filter that prevents the virtual FHRP MAC address from being announced to other sites.
  • C. Remove the VLAN from which FHRP hellos are sent from the extended VLAN range.
  • D. Configure the same FHRP priority on all the OTV edge devices in both sites.
  • E. On the OTV edge devices, configure an IP ACL that prevents hosts from reaching the FHRP master router on the other site.

Without having access to Fabric Path show commands, how can you confirm whether Fabric Path is configured on the two vPC peers 7K-3 and 7K-4?

  • A. Show vpc would not indicate any downstream virtual port channel vPC parameter with active VLANs
  • B. Show vpc role on both 7K-3 and 7K-4 would indicate their role as primary
