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

On an N-Series switch, which three outputs display when a network engineer runs the command show system?
(Choose three.)

• A.System name
• B.VLAN information
• C.Unit Temperature state
• D.Fan status
• E.Interface status
• F.OS version

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?

• A.CST configuration for the root bridge of all VLANs on the N-Series switches.MST configuration of the N-Series.
• B.MST configuration of the N-Series.Spanning-tree priority values on the Cisco stack.
• C.Information of the port-channel on the Cisco stack to the N-Series VLT pair.Requirement for "intf-type cr4 autoneg" applied on all 10 Gb ports on the N-Series switch pair.
• D.Static routes that are required for redistribution into OSPF on the Dell switches.Spanning-tree priority values on the Cisco stack.

Refer to the exhibit.
On switch S4820-2, commands are entered. The associated output is a follows:

Which command MUST have been entered previously on switch S4820-1?

• A.S4820-1 (conf-pvst)#vlan 2 bridge-priority 4096
• B.S4820-2 (conf-pvst)#vlan 2 bridge-priority 20480
• C.S4820-1 (conf-pvst)#vlan 3 bridge-priority 4096
• D.S4820-1 (conf-pvst)#vlan 3 bridge-priority 20480

Two Dell S-Series Switches are directly connected.

Which statement describes what will happen when a ping is sent from Dell-1 to Dell-2?

• A.Ping will not work because of MTU Mismatch.
• B.LLDP shows 0/37 is connected to 0/39 and pings will be successful.
• C.Link is Operationally up; therefore, pings will work.
• D.Ping will not work because of IP Network Mismatch.
