---

Question1: Which settings should match on physical interfaces before a network combines them in a link aggregation?

Question2: A network administrator configures OSPF in a network with ArubaOS switches. The administrator is concerned that a rogue device might connect to an access layer switch and introduce OSPF routes to the company's routing topology. The access VLANs do not contain additional routers.
What should the administrator do so switches do not form an adjacency with rogue devices on the access VLANs?

Question3: Refer to the exhibit.

The network administrator enters this command:
Switch(config)# ip route 172.16.2.0/30 192.168.1.100 metric 1 distance 1 Why does this route fail to appear in the IP routing table?

Question4: Which benefit does Aruba Clarity in Aruba AirWave provide?

Question5: A company has a single routing protocol environment.
What is one reason to use OSPF routing instead of static routing?

Question6: Refer to the exhibit.

Prior to implementing OSPF on the network, an ArubaOS switch had the IP routing table shown in the exhibit. The network administrator then sets up OSPF in the network. The switch calculates these OSPF routes to 10.1.20.0/24:
Through 10.1.0.1 with cost 3 and administrative distance 110

Through 10.1.0.2 with cost 3 and administrative distance 110

How does the way the switch handles traffic destined to 10.1.20.0/24 change with the introduction of OSPF?

How can the administrator find a valid way to complete the command?

Question11: Refer to the exhibits.
Exhibit 1

Exhibit 2

A network administrator wants to create a backup IP route to 10.1.20.0/24 on Switch-1. The backup route should use Link2, and it should only be used if Link1 is down.
What is the correct setup to accomplish this?

Question12: A network administrator creates a local user account and assigns that account to the Level-9 authorization group. The administrator tests the group assignment and is able to successfully log in with the local user credentials. However, the administrator is able to enter all the commands rather than only the commands permitted by the Level-9 group.
How can the administrator resolve this issue?
