Q2. Refer to the exhibit.

Q3. A network engineer needs to make sure that the first 16 switchports on an S-Series switch are enabled for immediate forwarding when a computer or server is connected. The ports must be shut down if a switch with default configuration is connected. The S-Series switch is already configured for IEEE 802.1w.
Which commands meet the requirements for the switchports?
A.
B.
C.
D.
Answer: B
Q4. Refer to the exhibit.
The deployment engineer needs to use rapid PVST+ so that some traffic is forwarding on all inter-switch links on these three N-Series Switches. To do so, each switch has been set to the lowest spanning-tree priority value for one of the VLANs.
Given the labeled diagram shown, what Spanning-Tree Priority is Switch B advertising for VLAN 20?
A. 4096
B. 0
C. 32788
D. 4116
Answer: B

A.
B.
C.
D.
Answer: C

B. S-Series Globally EnabledN-Series Globally Disabled
C. S-Series Globally EnabledN-Series Globally Enabled
D. S-Series Globally DisabledN-Series Globally Enabled
Answer: D
Q8. In an OSPF network, a network engineer uses a loopback interface with an assigned IP Address instead of configuring an IPv4 address as the Router I.
What are two benefits of this choice? (Choose two.)
A. OSPF is more reliable when a loopback interface is configured because a loopback interface is always active.
B. The loopback interface does not require a different subnet to be configured on each switch.
C. Not using a loopback interface saves real IP address space that can be used in the future.
D. The loopback interface IP address when advertised via OSPF can be used as a reliable remote management IP address.
Answer: A,D
Q9. A network engineer removes a new Dell Networking N-Series switch from the original shipping container and initially configures STP on the switch. While the engineer is working on another task, another individual modifies the VLAN 1 STP priority to 61440, and has saved to the startup configuration.
Which command should be issued to return the switch to the default STP priority value for VLAN 1?
A. console(config)#spanning-tree priority 4096
B. console(config)#spanning-tree priority 16384
C. console(config)#spanning-tree priority 32768
D. console(config)#spanning-tree priority 65536
Answer: C
Q10. A network engineer is verifying the configuration of a LAG connection on an S-Series switch.
Which two commands should the network engineer use to determine the operation of the LAG? (Choose two.)
A. show lacp <interface>
B. show interface <port-channel number>
C. show port-channel-flow <interface>
D. show uplink-state-group <port-channel number>
Answer: A,B
Q11. A networking engineer needs to configure several VLANs for S-Series switches for both Untagged and Tagged traffic.
Which three of the following apply? (Choose three.)
B. A Tagged interface can be a member of multiple VLANs.
C. Hybrid ports can be assigned to both an Untagged VLAN and Tagged VLAN.
D. When a Tagged interface is removed from a VLAN, it will always be placed in the default VLAN as a Tagged interface.
E. Hybrid ports can be assigned to multiple VLANs but not the default VLAN.
F. When a Tagged interface is removed from a VLAN, it will remain Tagged only if it is Tagged in another VLAN.
Answer: B,C,F
Q12. Which three cabling items should be considered when stacking N4000 Series switches? (Choose three.)
A. Use interfaces with the same bandwidth between stack members.
B. Use a cascade topology for redundancy between stack members.
C. A QSFP+ breakout cable cannot be used for stacking between members.
D. Ports from an installed expansion module are not supported with stacking.
E. A QSFP+ port should be counted as a single port when used for stacking.
F. Up to eight ports may be used on any switch for stacking purposes.
Answer: A,E,F
Q13. By default, how often are Bridge Protocol Data Units (BPDUs) sent with reference to 802.1w?
A. every 15 seconds
B. every 2 seconds
C. every 5 seconds
D. every 30 seconds
Answer: B
Q14. A network engineer configures a new S-Series switch. When the network engineer reloads the switch, the running configuration is defaulted.

B. The flash memory is corrupt and the switch needs to be replaced.
C. The switch was left in BMP mode.
D. The switch could not find a default FTP server for a configuration file.
