Question List

Question1: An administrator will be replacing a campus switching infrastructure with AOS-CX switches that support VSX capabilities. The campus involves a core, as well as multiple access layers. Which feature should the administrator implement to allow both VSX-capable core switches to process traffic sent to the default gateway in the campus VLANs?

Question2: Examine the network exhibit.

A company has a guest implementation for wireless and wired access. Wireless access is implemented through a third-party vendor. The company is concerned about wired guest traffic traversing the same network as the employee traffic. The network administrator has established a GRE tunnel between AOS-CX switches where guests are connected to a routing switch in the DMZ.
Which feature should the administrator implement to ensure that the guest traffic is tunneled to the DMZ while the employee traffic is forwarded using OSPF?

Question3: Examine the commands entered on an AOS-CX switch:
What is true regarding this configuration for traffic received on interface 100?

Question4: Examine the attached diagram.

The two PCs are located in VLAN 11 (10.1.11.0/24). Which example defines how to implement active gateway on the VSX core for VLAN 11?

Question5: An administrator has an AOS-CX switch configured with:
router ospf 1
area 0
area 1 stub no-summary
It is the only ABR for area 1. The switch has the appropriate adjacencies to routing switches in areas 0 and 1.
The current routes in each area are:
Area 0: 5 routes (LSA Type 1 and 2)
Area 1: 10 routes (LSA Type 1 and 2)
External routes: 2 (LSA Type 5)
Based on the above configuration, how many OSPF routes will routing switches see in Area 1?

Question6: A network administrator is managing a network that deploys a multicast service. The administrator has multiple streams successfully being routed by PIM-DM in the network. The administrator then adds a new stream with a destination address of 239.0.0.1. However, clients who have not joined the stream are receiving it.
What should the administrator do to fix this problem?

Question7: A company has just purchased AOS-CX switches. The company has a free and open-source AAA solution.
The company wants to implement access control on the Ethernet ports of the AOS-CX switches.
Which security features can the company implement given the equipment that they are using?

Question8: A network administrator is implementing a configuration plan in NetEdit. The administrator used NetEdit to push the configuration plan to the switch. Which option in the NetEdit planning section should the administrator select to save the configuration running on the switch to the startup-config?

Question9: A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server. The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.
What is correct regarding the ERSPAN session that needs to be established on an AOS-CX switch? (Choose two.)

Question10: A network engineer is having a problem adding a custom-written script to an AOS-CX switch's NAE GUI.
The script was written in Python and was successfully added on other AOS-CX switches. The engineer examines the following items from the CLI of the switch:

What should the engineer perform to fix this issue?

Question11: A network engineer is using NetEdit to manage AOS-CX switches. The engineer notices that a lot of thirdparty VoIP phones are showing up in the NetEdit topology. The engineer deletes these, but they are automatically rediscovered by NetEdit and added back in.
What should the administrator do to solve this problem?

Question12: An administrator wants to leverage always-on PoE on AOS-CX switches. Which statement is correct regarding this feature?

Question13: An administrator is looking for a data center switching solution that will greatly reduce the likelihood of dropped frames when uplink congestion is experienced. Which AOS-CX switch queuing feature meets the administrator's needs?

Question14: Which protocol does NetEdit use to discover devices in a subnet during the discovery process?

Question15: How is voice traffic prioritized correctly on AOS-CX switches?

Question16: An administrator is defining a VSX LAG on a pair of AOS-CX switches that are defined as primary and secondary. The VSX LAG fails to establish successfully with a remote switch; however, after verification, the remote switch is configured correctly. The administrator narrows down the problem to the configuration on the AOS-CX switches.
What would cause this problem?

Question17: How should a network administrator add NAE scripts and implement NAE agents that will run on an AOS-CX switch?

Question18: Which protocols are used by NetEdit to interact with third-party devices? (Choose two.)

Question19: An administrator is concerned about the security of the control plane connection between an AOS-CX switch and an Aruba Mobility Controller (MC) when implementing user-based tunneling. How should the administrator protect this traffic?

Question20: A network engineer for a company with 896 users across a multi-building campus wants to gather statistics on an important switch uplink and create actions based on issues that occur on the uplink. How often does an NAE agent gather information from the current state database in regard to the uplink interfaces?

Question21: The network is configured for OSPF with the following attributes:
Core1 and Core2 and ABRs
Area 1 has 20 networks in the 10.1.0.0/16 range
Area 0 has 10 networks in the 10.0.0.0/16 range
Area 2 has 50 networks in the 10.2.0.0/16 range
The ASBR is importing a static route into Area 1
Core2 has a summary for Area 2: area 0.0.0.2 range 10.2.0.0/16 type inter-area Here is the OSPF configuration performed on Core1:

Based on the above information, what is correct?
