Question 4
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.)

- 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

Answer : D
Question 6
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.
Answer : AC
Explanation:
Dell Networking N1500 Series switches stack using the 10G SFP+ front-panel ports.
N1500 does not support OSPF.
