Question15: A network administrator needs to replace an antiquated access layer solution with a modular solution involving AOS-CX switches. The administrator wants to leverage virtual switching technologies. The solution needs to support high-availability with dual-control planes.
Which solution should the administrator implement?

Question16: 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?

Question17: An administrator wants to implement dynamic segmentation policies. The network consists of AOS-CX and Aruba gateways.
Which type of forwarding should the administrator implement for users that already connect via wireless, but will also be connecting on Ethernet switch ports?

Question18: Examine the network exhibit.

A network administrator is implementing OSPF on a VSX pair of aggregation switches: Agg1 and Agg2. VLANs 10 and 20 are connected to layer-2 access switches. Agg-1 and Agg-2 are configured as the default gateway for VLANs 10 and 20, with active gateway enabled.
What is the best practice for configuring OSPF on the aggregation switches and their connection to the Core switch?

Question19: A network administrator is implementing OSPF, where there are two exit points. Each exit point has a stateful, application inspection firewall to implement company policies.
What would the best practice be to ensure that one firewall will see both directions of the traffic, preventing asynchronous connections in the network?

Question20: 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?

Question21: What is the correct way of associating a VRF instance to either a VLAN or an interface?

Question22: Examine the attached diagram

Two AOS-CX switches are configured for VSX at the access layer, where servers attached to them. An SVI interface is configured for VLAN 10 and serves as the default gateway for VLAN 10. The ISL link between the switches fails, but the keepalive interface functions. Active gateway has been configured on the switches.
