Question1: Which privilege level would a network administrator use to configure an ArubaOS switch?

Question2: A network administrator just received two switches and wants to use the plug-and-play method to establish a Virtual Switching Framework (VSF) fabric with the fewest steps possible.

Which Aruba solutions provide Zero Touch Provisioning (ZTP) for Aruba Instant APs (IAPs) and ArubaOS switches?

Question5: Refer to the exhibit.

Spanning tree runs on the switches shown in the exhibit. The network administrator enters these two commands:
Switch-1(config)# spanning-tree priority 0
Switch-2(config)# spanning-tree priority 1
The other switches use the default spanning tree priorities. The administrator enters the show spanning-treecommand on Switch-2.
If the configuration is correct, which roles will the output show?

Question6: 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?

Question7: A company has an Aruba 5400R switch, switch 1, at the network core of its campus. This switch routes all traffic for the campus and is the RSTP root. The company now wants to add another Aruba 5400R switch to the core in order to enhance resiliency. The company wants to use the option that provides the best Layer 2 and Layer 3 resiliency and also the simplest setup.
What should the administrator do to add the new 5400R switch?

Question8: How many operating system image files can a network administrator load on an ArubaOS switch?

Question9: What is one benefit that Aruba AirWave can provide to a customer with ArubaOS switches?

Question10: A network administrator needs to configure a link aggregation on an ArubaOS switch.
For which type of link aggregation is the administrator required to enter the lacpcommand in the interface context?

Question11: Refer to the exhibit.

The network administrator wants to place contractor clients and employee clients in different broadcast domains.
How should the administrator achieve this goal?

Question12: Refer to the exhibit.
Exhibit 1.

Exhibit 2.

Which devices can communicate with each other at Layer 2?

Question13: For which task does a network administrator need to access the enable context on an ArubaOS switch?

Question14: Managers log in to an ArubaOS switch with SSH.
What does SSH require to authenticate the switch to the SSH client and set up a secure session?

Question15: An ArubaOS switch operates at its factory default settings. A network administrator connects the switch to a VLAN with a DHCP server. The switch-to-switch connection carries untagged traffic. The administrator wants to use Telnet log in to the switch CLI.
How should the administrator contact the switch and log in?

Question16: Refer to the exhibit.

All of the switches shown in the exhibit are ArubaOS switches.
Where should the network administrator configure an IP helper address of 10.1.1.10?

Question17: Refer to the exhibit.

A network administrator views the configuration files on an ArubaOS switch and sees the output in the exhibit. The administrator enters this command:
Switch# boot system flash primary config config2
After the switch boots, the administrator makes some configuration changes and saves the configuration with the write memory command. The administrator then enters this command:
Switch# boot
After the switch boots, the configuration changes just made are not present.
How can the administrator restore the configuration with the changes?

Question18: Refer to the exhibit.

Originally, all four switches had the same region configuration. VLAN 14 was added to Switch_D and then mapped to instance 2.
How does this affect the MSTP topology?

Question19: A network administrator configures MSTP on an ArubaOS switch. The administrator wants to ensure that this switch is always the root for instance 1.
What should the administrator do to accomplish this?

Question20: Refer to the exhibit.

The network consists of two ArubaOS switches with routing disabled.
How should the network administrator configure the link between Switch A and Switch B to ensure that all hosts can communicate to all the other hosts within their respective VLANs?

Question21: Which settings should match on physical interfaces before a network combines them in a link aggregation?

Question22: Two switches are members of a Virtual Switching Framework (VSF) fabric.
Which statement correctly describes how the switches handle routing?

Question23: Refer to the exhibit.
Exhibit 1.

Exhibit 2.

The routing configuration must support this behavior:
Server 1 and Server 2 communicate over Link 1 when Link 1 is up.
If Link 1 fails, Server 1 and Server 2 can continue to communicate over the path through Switch-3.
What must the network administrator change to meet these criteria?

Question24: How does a switch treat a link aggregation?

Question25: Which type of 802.11 wireless network can be hosted by an endpoint device such as a laptop?

Question26: Refer to the exhibit.

Which links can be combined in the same link aggregation?

Question27: Refer to the exhibit.

A network administrator executes this command on an ArubaOS switch, Switch-2:
Switch-2(config)# ip route 10.1.100.0/24 10.1.1.1
The administrator successfully pings Device 1 at 10.1.100.42 from Switch-2. However, Device 2 cannot ping Device 1.
The administrator confirms that Device 1 is correctly set up.
What should the administrator check on Switch-2 to resolve this issue?

Question28: Refer to the exhibit.
Exhibit 1.

Exhibit 2.

Assume that Switch-2 is correctly configured for OSPF.
Which additional step must the administrator take to enable Switch-1 to advertise 192.168.2.0/24 to Switch-2?

Question29: A company has ArubaOS switches that are already configured to support the network. The company now wants to use Aruba AirWave to manage the switches. The network administrator creates a new group on Aruba AirWave, and then discovers several ArubaOS switches that should belong to this group.
What is the best practice for the initial authorization of the switches in AirWave?

Question30: Refer to the exhibit.

A company has an existing Aruba Instant cluster with several Instant APs (IAPs), as shown in the exhibit.
The network administrator orders a new IAP and boots it for the first time by connecting it to the PoE switch port shown in the exhibit.
What happens after the IAP boots?

Question31: Refer to the exhibit.

What should the network administrator do to permit Switch-1 to route traffic from a client in 10.1.11.0/24 to a client in 10.1.12.0/24?

Question32: A network administrator plans to set up a WLAN on an Aruba Instant cluster. The WLAN uses WPA/WPA2 Enterprise security. The administrator wants no authenticate users locally on the cluster.
How should the administrator configure me credentials?

Question33: Refer to the exhibit.
Exhibit 1.

Exhibit 2.

The administrator enters the show spanning-treeinstance 2 command on Switch-3 and sees the output shown in Exhibit 2.
