A network administrator needs to control traffic based on TCP or UDP application, as well as IP protocol, such as GRE or ICMP. What should the administrator configure for this purpose?
A network administrator applies port security to a port with the send-alarm action. What does the switch do if it detects traffic from an unauthorized MAC address on the port?
The security plan for AOS-Switches calls for ARP protection. For ARP protection to function properly, which other feature should also be implemented?
A network administrator needs to configure VRRP on VLAN 2 on two AOS-Switches. Which two settings must match on both switches?
An architect proposes several Aruba 2930M switches, which the customer wants to combine into a single logical switch. What must be included in the proposal to meet this requirement?
Which situation requires an AOS-Switch interface to support MAC-based VLANs?
Refer to the exhibit.
An AOS-Switch connects to an unmanaged switch in a meeting room. The exhibit shows security settings for this port. Users report that they sometimes lose connectivity and then get it back.
Which best practice should network administrators follow to avoid this issue?
What must an OSPF router do to ensure nonstop routing should a standby member take over as commander when the original VSF commander fails?
An AOS-Switch enforces 802.1X authentication to an Aruba ClearPass server. A user connects but cannot receive network access, even though the ClearPass administrator finds an Access-Accept for the user on this switch. The switch administrator suspects that there is an issue with the dynamic settings returned by ClearPass.
Where should the administrator look for information about these settings?
Refer to the exhibit.
A network administrator needs to deploy AOS-Switches that implement port-based tunneled node. Their Aruba controller has IP address 10.1.10.5/24. The architect has assigned tunneled-node endpoints to VLAN 20.
What is one issue with the current configuration planned for VLAN 20 on the switch?
Refer to the exhibit.
An AOS-Switch has an extended ACL that is applied to several physical interfaces.
- New interfaces have been brought online.
- The ACL has been applied to them as well.
A network administrator sees the output in the exhibit and is concerned that the switch will reach the limit for rules.
What can the administrator do to address this concern?
Refer to the exhibits.

The network administrator enters the commands shown in Exhibit 2. What is the spanning tree status on A1 and A2?
A network administrator needs to configure an AOS-Switch to classify traffic. Comparing QoS policy and global policy, what is one function that only a class-based QoS policy can fulfill?
Refer to the exhibits.
Exhibit 1
Exhibit 2
A company has attempted to implement OSPF without success. The devices in Area 1 need to be able to reach Area 2. Routes should be aggregated for advertisement in other areas. What must be changed to meet these requirements?
Refer to the exhibits.
Exhibit 1
Exhibit 2
In the exhibits, VLAN 20 under a device name indicates that the device is configured with that VLAN. The exhibits also indicate whether VLAN 20 is statically configured on each link, either as an untagged or a tagged VLAN. If the link has no label, VLAN 20 is not statically configured on that link.
A network administrator needs to deploy AOS-Switches that use port-based tunneled node. The plan calls for tunneled-node endpoints to be assigned to VLAN 20 and for the Aruba Mobility Controller to handle the tunneled-node traffic at Layer 2. Which exhibit shows the correct plan for VLAN 20 in the wired infrastructure?
A company wants to implement RADIUS authentication of all managers who log in to AOS-Switches via SSH. The RADIUS server also sends VSAs that indicate which commands users can enter, and switches must honor these.
What must the administrator do to meet the company’s requirements?
A network administrator needs to control traffic based on Ethertype and Class of Service. What should the administrator configure for this purpose?
Which technologies can prevent split brain in a VSF fabric that includes Aruba 2930F switches?
Refer to the exhibits.
Exhibit 1
Exhibit 2
Exhibit 1 shows a portion of the BGP routing table when the BGP solution was first deployed. Exhibit 2 shows the same portion at the current time. What can explain the current state?
Refer to the exhibit.
AOS-Switches will enforce 802.1X authentication on edge ports. The company has two RADIUS servers, which are meant to provide redundancy and load sharing of requests. The exhibit shows the planned RADIUS settings to deploy to the switches.
What should customers understand about this plan?
A customer wants to authenticate AOS-Switch managers to a RADIUS server. The CIO wants to assign different rights to different management users for granular control over their rights and privileges. What must the network administrator enable on the AOS-Switches to ensure they comply with this plan?
A network administrator needs to create a backplane stack with four AOS-Switches. The administrator wants to choose which switch becomes the commander. Which procedure meets those needs?
Refer to the exhibits.
Exhibit 1.
Exhibit 2.
The exhibits show the current operational state for routes on Switch-3 to send all traffic to 172.16.0.0/16 through Switch-2 during normal operation.
Which single configuration change creates the desired behavior?
A customer wants access layer switches that support routing, ACLs, backplane stacking, and Smart rate ports. The customer asks about Aruba 5400R z 12 switches.
Which Aruba Switch model would better meet the customer’s requirements?
Network administrators need to inspect all traffic that arrives on an AOS-Switch in VLAN 2 and is destined to TCP ports 50000-50010. They want to send the traffic to a protocol analyzer connected to the switch for deeper inspection.
What else must they create to achieve their goal?
