DNDNS-200 Question #85: Real Exam Question with Answer & Explanation

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 will be connected to the new switches with 40Gb N-Series uplink to provide a migration path. The default gateway exists as another entity and will connect to N-Series switch ports 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 switches will be configured with VLT.
• The switches will have several VLANs configured.
• The management VLAN will be MLAG.
• The N-Series will not provide Layer 3 services 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 customer has verified that the N-Series switches have the latest OS and that all necessary 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 will not use any SFP+ copper cables because of their costs.
• They use StackWise technology, and therefore are stacked.
• The pair of N-Series switches will be full of 100 Mbps, 1G, 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 N-Series switches will be configured with Rapid-PVST and default bridge priorities.
• The version of firmware, also known as the IOS, is up to date before implementing the deployment and cutover plan. What two pieces of information are required to finalize the plan?
