Refer to the exhibits. Exhibit 1.

Exhibit 2.

The company wants to minimize congestion on Link 1.

Which spanning tree implementation meets this goal?

A. Instance 1 = VLANs 4-5 Instance 2 = VLANs 6-7 Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1 Switch 3 instance 1 priority = 1 Switch 3 instance 2 priority = 0

B. Instance 1 = VLANs 4,6 Instance 2 = VLANs 5,7 Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1 Switch 3 instance 1 priority = 1 Switch 3 instance 2 priority = 0

C. Instance 1 = VLANs 4,6 Instance 2 = VLANs 5,7 Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1 Switch 3 instance 1 priority = 0 Switch 3 instance 2 priority = 1

D. Instance 1 = VLANs 4-5 Instance 2 = VLANs 6-7 Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1 Switch 3 instance 1 priority = 0 Switch 3 instance 2 priority = 1

Network administrators need to configure a BGP neighbor on an AOS-Switch. What defines the neighbor as an iBGP neighbor?

A. It has BGP synchronization enabled.

B. It has an AS number in the range of 64512 to 64535.

C. Its update source is set to a private company IP address.

D. Its remote-AS is the same as the AOS-Switch BGP AS.

Refer to the exhibit.

Several interfaces on an AOS-Switch enforce 802.1X to a Radius server at 10.254.202.202. The interface 802.1X settings are shown in the exhibit, and 802.1X is also enabled globally. The security team have added a requirement for port security on the interfaces as well.

Before administrators enable port security, which additional step must they complete to prevent issues?

A. Set 802.1X client limit on the interfaces.

B. Manually add legitimate MAC addresses to the switch authorized MAC list.

C. Enable DHCP snooping on VLAN 20.

D. Enable eavesdropping protection on the interfaces.

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. 2530

B. 2930F

C. 3810

D. 8400

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 entirely and cannot route traffic between each other at all.

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 in Area 1 and must route all traffic to each other through Area 0.
