A network engineer removes a new Dell Networking N-Series switch from the original shipping container and initially configures STP on the switch. While the engineer is working on another task, another individual modifies the VLAN 1 STP priority to 61440, and has saved to the startup configuration.
Which command should be issued to return the switch to the default STP priority value for
VLAN 1?

  • A. console(config)#spanning-tree priority 4096
  • B. console(config)#spanning-tree priority 16384
  • C. console(config)#spanning-tree priority 32768
  • D. console(config)#spanning-tree priority 65536


Answer : C

A customer needs to convert S-Series stacked switches to a VLT configuration to maintain port-channels from the customers server. The customers S-Series stack currently uses
IEEE 802.1d. The customer wants to upgrade to a faster converging protocol. The servers that connect to the stack use static port-channels, but the customer wants to be IEEE
802.3ad compliant. The customer has approved a maintenance window for the weekend to make these changes.
A network engineer has been given the following plan:
- Confirm the timings of the change window with the customer
- Upgrade the firmware of the S-Series switches
- Configure the single-domain VLT peers
- Configure the port-channels down to the customers servers
- Utilize all existing cabling to proceed with the plan
Based on the provided plan, which two pieces of information does the engineer need to proceed? (Choose two.)

  • A. the requirement of IEEE 802.1w for VLT Support
  • B. the time-out value for ARP-cache
  • C. the version of VLT that is required to meet IEEE 802.1s compliance
  • D. the requirement for servers to actively negotiate an IEEE 802.3ad LAG
  • E. the new 802.1s bridge priority after the cutover
  • F. the static mac-address assignment to ensure that all end servers are aware of the Root Bridge


Answer : E,F

The network engineer powers on a new S-Series switch. None of the devices connected to this new switch are responding to pings.
Which two conditions should the network engineer verify? (Choose two.)

  • A. an ARP table is configured
  • B. the switch has a default Gateway
  • C. ports are not shut down
  • D. OSPF is enabled
  • E. ports are in switchport mode


Answer : A,C

What are three characteristics of port-based VLANs on S-Series switches? (Choose three.)

  • A. FTOS supports 4093 port-based VLANs and one default VLAN.
  • B. Untagged interfaces do not need to be part of a VLAN.
  • C. Port-based VLANs should only be used in large-scale deployments.
  • D. Port-based VLANs offer increased security for traffic, conserve bandwidth, and allow switch segmentation.
  • E. Different VLANs do not communicate with each other unless IP routing is configured.
  • F. FTOS supports 4094 port-based VLANs and one default VLAN.
