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

A network deployment engineer needs to deploy four Dell Networking N1500 series switches. All switches are to be stacked together using 10Gbe ports on each switch and implement OSPF per the deployment plan. The customer has been shipped only the four switches with SAS stacking cables. No other equipment has been shipped.

Which two issues occur when the network engineer tries to stack all four switches and implement OSPF? (Choose two.)

A. Incorrect cabling was shipped for stacking instead of the required 10Gbs TwinAx.

B. The N1500 series switches do not support advanced Layer 3 Functionality.

C. The N1500 series switches support Layer 3 lite Functionality.

D. Stacking is limited to only four switches because of the limited back-plane bandwidth.

E. Stacking modules were provided as per the deployment.

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.

In an OSPF network, what happens if the OSPF Priority level is set to "0"?

A. The switch does not become an active BDR or DR.

B. The switch becomes the BDR in the OSPF routing topology.

C. The switch becomes the DR in the OSPF routing topology.

D. The switch does not participate as a member in the OSPF network.

On an S-Series switch, what two events occur when a static null route has been configured in the system to drop a packet? (Choose two.)

A. Null route is installed in the PBR table to drop the packet

B. Null route is saved into the running configuration.

C. Null route is installed in the ACL table with deny statement.

D. Null route is installed in the IP forwarding table.
