A network administrator sets up MAC-Auth and captive portal to Aruba ClearPass on AOS-Switches. The solution seems to work for most guests. However, some guests open their browsers and are not redirected to the captive portal.
How should the administrator address the likely cause of the issue?
Refer to the exhibits.

The network administrator enters the commands shown in Exhibit 2. What is the spanning tree status on A1 and A2?
Refer to the exhibit.

Switch-1 and Switch-2 are configured to provide VRRP in VLAN 2. Based on the output, what will happen when a client in VLAN 2 sends an ARP request for its default gateway IP address?
Refer to the exhibit.

The network administrator wants to reduce failover time if a switch link in VLAN 100 goes down. What should the administrator do?
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?
A company wants to implement 802.1X authentication to authenticate client devices on AOS-Switch ports.
The company has a RADIUS server that uses PEAP MSCHAP-v2 for the authentication method. What is one task administrators should complete before they implement the plan?
Refer to the exhibit.

A network administrator needs to alter myACL so that it permits all traffic that arrives in VLAN 2 and is destined to 10.1.10.0/24. Besides this change, the ACL must continue to act as it does now. The administrator plans this new rule:
permit ip any 10.1.10.0/24
How should the administrator apply this rule to meet all requirements?
A network administrator needs to set up an AOS-Switch to use port-based tunneled node for connected devices. However, the administrator wants the switch to forward traffic without tunneling if it cannot reach a tunneled-node server.
What should the administrator do?
Two 5400R AOS-Switches are OSPF neighbors. The network administrator wants routing paths to update as quickly as possible in the event of a failure on a neighboring switch.
Which technology should the administrator implement on the connected switch interfaces?
Network administrators need to track when traffic matches deny entry in an ACL applied to a port. They want the alert to be sent to a syslog server that is already set up to send logs.
What should administrators do to enable alerts?
Refer to the exhibits.

Exhibit 2 shows IGMP groups on Switch-2, which runs IGMP but not PIM. Switch-1 and Switch-3 do not have IGMP or PIM enabled. Client 1 begins to forward multicasts to 239.1.1.1.
Which clients receive the multicasts?
Network administrators need to configure a BGP neighbor on an AOS-Switch. What defines the neighbor as an iBGP neighbor?
Refer to the exhibit.

The company wants the fastest convergence and best load sharing of traffic over the links between Switch-1 and the VSF fabric. Which technology should the network administrator implement on these links?
Refer to the exhibits.
