A customer needs to convert S-Series stacked switches to a VLT configuration to maintain port-channels from the customer's server. The customer's 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 customer's 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
A network engineer needs to install five Dell N-Series switches in a stack for a company that is moving to a new building.

What needs to be provided to enable the network engineer to complete this task?
A.
Serial cables
B.
TwinAx cables
C.
Memory RAM
D.

Refer to the output.
According to the partial configuration, which two things have occurred? (Choose two.)
A. All the configured neighbors are in autonomous system 200.
B. Three AS-path filters are applied to each BGP neighbor.
C. The peer group shortens the IBGP configuration.
D. Only the outgoing filters are applied to BGP updates.
E. The peer group shortens the EBGP configuration.
Refer to the exhibit.
On switch S4820-2, commands are entered. The associated output is a follows:
