Both Switch-1 and Switch-2 redistribute RIP routes into OSPF. The network administrator wants routers in Area 1 to receive the redistributed routes from Switch-1 but not from Switch-2. Routers in other areas should receive the routes from Switch-2.
What should the administrator do to achieve this goal?

• A. Configure Area 1 as a stub area, and import the routes with a low metric on Switch-2.
• B. Configure Area 1 as a stub area, with no summaries on Switch-2.
• C. Configure a subnet range for Area 1 on Switch-2, and set the no-advertise option.
• D. Configure Area 1 as a Not So Stubby Area (NSSA) on all routing devices in Area 1.

A network administrator sets up 802.1X authentication to a RADIUS server on an AOS-Switch. The RADIUS server and user devices are both set up to use PEAP MSCHAPv2. The administrator tests the authentication and sees the output shown in the exhibit. Which issue could cause this output?

• A. The switch does not have a certificate for port-access installed on the switch
• B. The administrator entered the wrong password for the test account
• C. The switch port is set for user mode 802.1X, but the RADIUS server is set for port mode
• D. The RADIUS shared secret does not match on the switch and the server

A company does not require authentication for security, but AOS-Switches are set up to use local MAC authentication (LMA) to assign the correct VLAN and priority to IP phones. IP phones and computers belong to different VLANs. Each device is supposed to connect to a specific port, but sometimes users connect their devices to the wrong ports and cannot receive access without help from IT.
How can a network administrator configure the switches to eliminate this issue?

• A. Create a user role that applies the user VLAN, and set this role as the initial role.
• B. Set the address limit to 2 on the switch ports that apply LMA.
• C. Apply LMA to all edge switch ports, and set the unauth VLAN to the user VLAN.
• D. Add the MAC addresses for computers to the myPhones MAC group.

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?

• A. 2930F
• B. 3810
• C. 2530
• D. 8400

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?

• A. Replace expired certificates on the switches and set their usage to captive portal since some guests have an HTTPS homepage.
• B. Replace MAC-Auth on switch ports with Web-Auth because this authentication method offers more reliability with captive portal.
• C. Set the RADIUS server time window to 0 because some guest computers likely have the incorrect system time.
• D. Reconfigure the captive portal URL hash key on some of the switches, which likely have the wrong password.
