Aruba Certified Design Expert 8 Written Exam v1.0
Question 1
Refer to the exhibit.
The customer requires a solution for the writing closet shown in the exhibit. The closet serves the entire floor, which is wired for CAT5e cable. The closet has four
CAT5e cables to the data center 110 feet (34 m) away.
The switch or switches in this closet will need to support 100 wired endpoints and 16 AP-345s. The switch or switches must connect to the network core, Aruba
