Dell Networking Professional Exam (DNDNS-200) - Dell Exam Questions

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. On switch S4820-1, commands are entered. The associated output is as shown.



Which four commands must have previously been entered on switch S4820-1?

Refer to the exhibit. A customer plans to deploy a two-tier OSPF ECMP Core in the configuration shown. All uplinks to the spine are 40Gbps. All uplinks to the leaves are 10Gbps.

What should be the oversubscription rate for the spine?

Refer to the exhibit. A customer has a C-Series chassis using a 48-port PoE+ line card. A workstation connected to Gi 0/47 passes traffic as expected. When the customer connects a PoE phone to the interface, the phone does NOT power up. Which configuration should a network engineer set on the Gi 0/47 interface to provide power to the phone?

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