質問 5

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）Not using a loopback interface saves real IP address space that can be used in the future.

（B）OSPF is more reliable when a loopback interface is configured because a loopback interface is always active.

（C）The loopback interface does not require a different subnet to be configured on each switch.

（D）The loopback interface IP address when advertised via OSPF can be used as a reliable remote management IP address.

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

（B）Stacking modules were provided as per the deployment.

（C）Incorrect cabling was shipped for stacking instead of the required 10Gbs TwinAx.

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

（E）The N1500 series switches support Layer 3 lite Functionality.

質問 7

Refer to the exhibit. A network engineer receives reports of excessive OSPF convergence causing intermittent loss of connectivity across the entire networking fabric.
What should the engineer do to ensure that OSPF flapping adjacencies in one data center do not affect other data centers?

（A）Increase the hello and dead timers of each OSPF device

（B）Decrease the hello and dead timers of each OSPF device

（C）Ensure each OSPF device has a unique and statically set router-id

（D）Place each data center in its own area while maintaining Area 0
