A customer plans to migrate a pair of Cisco switches to a pair of 10 Gb Dell N-Series switches as the new Layer 2 Data Center Core. Per the plan, the Cisco switches are to be connected to the configured Dell N-Series switches to provide a migration path.

The default gateway exists as another entity and will connect to N-Series switchports in access mode. All end-devices are dual-homed to both Cisco switches. One connection from each server is to be moved to switchports on the N-Series switches. The configuration of the N-Series switches is as follows:

The N-Series switches will have MST turned on

The switches will have several VLANs configured

The N-Series switches will use MLAG

The N-Series will use 802.3ad link aggregation, and will not actively negotiate a connection

The customer has established that the power requirements have been met for the new N-Series switches

The correct power-cabling, QSPF+ to 4xSPF+ breakout cables, QSPF+ to QSPF+ DACs, and Ethernet cables have shipped, with the switches.

The breakout cables will be used on the 40 Gb ports of the N-Series switches, which will connect out to the 10 Gb ports on the Cisco switches. The customer has provided the following information about the Cisco switches:

They use StackWise technology, and therefore are stacked

The type of switches are Catalyst 3850s, with 48-port 10/100/1000 copper connections and 4x10 Gb SFP+ ports

The Cisco stack currently uses Rapid-PVST, and all bridge-priorities are administratively set to make the CiscoStack the Root Bridge

The 10 Gb ports are a part of a port-channel that will connect to the N-Series switch

The version of firmware, also known as the iOS, is up to date before implementing the deployment and cutover plan.

Which two pieces of information are required to finalize the plan?

Refer to the exhibit. A network engineer receives reports of excessive OSPF convergence causing intermittent loss of connectivity across the entire networking fabric.

What should the engineer do to ensure that OSPF flapping adjacencies in one data center do not affect other data centers?

Refer to the exhibit. Given the output shown, which application IDs make up the default routing instance?

What does a flashing Red System LED on an S-Series switch indicate?

Refer to the exhibit. A customer installs a non-PoE line card to replace a previously installed PoE line card in slot 0. After unseating the line card, which two commands should a network engineer use to prepare the switch to accept the new line card?
