A. vSwitch
B. control node
C. vRouter
D. compute node
Correct Answer: C
New Question 3:
You are creating a design proposal and deciding whether to use 10 GbE copper or 10GbE fiber cabling to connect your ToR switches to the servers.
Which statement is correct regarding this scenario?
A. Fiber has a lower power consumption on a per-port basis.
B. Copper cabling requires special transceivers for different speeds.
C. Fiber is much cheaper to purchase but has a higher long-term cost.
D. Copper will allow you to reach the greatest distance between devices.
Correct Answer: A

New Question 5:
A customer has selected QFX5110 switches. The initial installation will contain two switches located in racks about two meters apart. What is the most cost-effective way to interconnect these switches?
A. Use SMF between the racks and interconnect the switches with LX4 transceivers.
B. Use a Virtual Chassis cable between the VCP cards.
C. Use MMF between the racks and interconnect the switches with SR4 transceivers.
D. Use a three-meter passive DAC cable between the racks and interconnect the switches with it.
Correct Answer: D

A. You should use BA classifiers on R1.
B. You should use multifield classifiers on R2, R3, and R4.
C. You should use multifield classifiers on R1.
D. You should use BA classifiers on R2, R3, and R4.
Correct Answer: AB
New Question 10:
You are designing an IP fabric using EBGP.
In this scenario, what are two ways of designing the ASN scheme for the IP fabric? (Choose two.)
A. Assign the same ASN to all devices.
B. Assign the ASN to all leaf devices and a separate ASN to all spine devices.
C. Assign a unique ASN to each individual device.
D. Assign the same ASN used by the WAN service provider to the spine devices.
Correct Answer: CD
New Question 11:

New Question 12:
Which two statements about heating and cooling design are correct? (Choose two.)
A. All devices in a rack should be installed so that the port panels are on the same regardless of the air flow direction.
B. All devices in a rack should be installed so that the air flow is in the same direction regardless of the port panel location.
C. In the hot-aisle/cold-aisle design, air enters through vents in the hot-aisle and exists through cold-aisle vents.
D. The hot-aisle/cold-aisle design maximizes the cooling potential of the air conditioning system.
Correct Answer: CD
