HP Delta-Aruba Certified Switching Professional Sample Questions:

1. AOS-Switches authenticate guests to ClearPass with captive portal. When guests first connect their device to the network, they are redirected to a captive portal in which they log in. ClearPass then stores the guest MAC addresses, and the guests are permitted access. Due to a conflict, the network administrator needs to change the dynamic authorization port, port 3799, on Aruba ClearPass.
If the administrator forgets to also change the port on one of the AOS-Switches, what will be one symptom?

A) When some guests successfully authenticate in the captive portal, they are redirected back to the portal page.
B) Some guests receive full access to the network when they first connect instead of being redirected to the portal page.
C) Some guests are unable to reach the captive portal page. Instead, they receive no access at all.
D) Guests are redirected to the system listening on port 3799.

2. Refer to the exhibits.
Exhibit 1

Exhibit 2

The exhibits show the current operational state for routes on Switch-3. The company wants Switch-3 to send all traffic to 172.16.0.0/16 through Switch-2.
Which single configuration change creates the desired behavior?

A) Set a cost of 15 in the redistribute static command on Switch-2.
B) Set a cost of 5 in the router ospf area 0.0.0.1 stub command on Switch-1.
C) Change the OSPF external metric type to 1 on Switch-1 and Switch-3.
D) Change the OSPF external metric type to 2 on Switch-1 and Switch-2.

3. Refer to the exhibits.
Exhibit 1

Exhibit 2

Network administrators are alerted to high interface utilization on a switch by a management solution. They examine the utilization on the uplink interfaces several times an hour during problem times. The exhibit shows output typical of times of congestion. The administrators want to allocate bandwidth fairly and reduce congestion on the uplinks.
What could help meet these requirements?

A) an outbound rate limit on each edge port
B) a per-queue rate limit on interfaces 1 and 2
C) a broadcast rate limit on each edge port
D) an outbound rate limit on interfaces 1 and 2

4. Refer to the exhibits.
Exhibit 1

Exhibit 2

A company has attempted to implement OSPF without success. The devices in Area 1 need to be able to reach Area 2. Routes should be aggregated for advertisement in other areas. What must be changed to meet these requirements?

A) Add the 10.2.0.0/16 range on Switch-1 and the 10.1.0.0/16 range on Switch-2.
B) Add Area 1 and Area 2 on VLAN 100 on both Switch-1 and Switch-2. Remove Area 3.
C) Move the 10.1.0.0/16 range to Area 2 on Switch-1 and the 10.2.0.0/16 range to Area 1 on Switch-2.
D) Change Area 3 to Area 0; remove Area 1 from Switch-2 and Area 2 from Switch-1.

5. OSPF Area 1 has two ABRs. One ABR is configured with this range for Area 1: 10.10.0.0/16. The other ABR is configured with this range for Area 1: 10.10.0.0/17.
Which type of issue occurs due to this mismatch?

A) The ABRs lose adjacency in Area 1 and must route all traffic to each other through Area 0.
B) The ABRs create a discontiguous area and disrupt intra-area routing between devices within Area 1.
C) The ABRs advertise routes inconsistently, and they could potentially introduce a routing loop.
D) The ABRs lose adjacency entirely and cannot route traffic between each other at all.
