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?

A) Define a layer-2 VSX LAG associated with a layer-3 VLAN interface. Enable active gateway for the Layer-3 VLAN.
B) Define separate layer-3 VLAN interfaces between the aggregation and core switches. Enable active forwarding for the Layer-3 VLAN.
C) Define separate layer-3 VLAN interfaces between the aggregation and core switches. Enable active gateway for the Layer-3 VLAN.
D) Define a layer-2 VSX LAG associated with a layer-3 VLAN interface. Enable active forwarding for the Layer-3 VLAN.

An administrator has an aggregation layer of 8325CX switches configured as a VSX pair. The administrator is concerned that when OSPF network changes occur, the aggregation switches will respond to the changes slowly, and this will affect network connectivity, especially VoIP calls, in the connected access layer switches. What should the administrator do on the aggregation layer switches to alleviate this issue?

A company has implemented 802.1X authentication on AOS-CX access switches, where two ClearPass servers are used to implement AAA. Each switch has the two servers defined. A network engineer notices the following command configured on the AOS-CX switches: radius-server tracking user-name monitor password plaintext aruba123 What is the purpose of this configuration?

An administrator will be implementing tunneling between AOS-CX switches and Aruba gateways. Which list of protocols must minimally be allowed by an intermediate firewall between two sets of devices?
