A network technician is installing an HPE Aruba Networking CX 6300M switch and needs to provide power to several connected devices, including security cameras and wireless access points, using Power over Ethernet (PoE). The total power requirement for these devices is 400 watts. When selecting a power supply for the switch, what hardware specification must the technician verify to ensure the switch can meet this demand?

A network technician is troubleshooting a user's complaint of being unable to reach a server. The technician uses the `ping` command from the user's default gateway (an AOS-CX switch) to the server's IP address (172.16.30.10) and receives a "Destination Host Unreachable" message. The technician then displays the switch's IP route table.
Review the routing table output:
show ip route
Codes: C - Connected, S - Static, R - RIP, O - OSPF, B - BGP > - Selected route, * - FIB route S > 0.0.0.0/0 [1/0] via 10.1.254.1, vlan1 C > 10.1.0.0/16 is directly connected, vlan1 C > 192.168.1.0/24 is directly connected, vlan100 O > 192.168.50.0/24 [110/1] via 10.1.1.2, vlan1 Based on the routing table, what is the most likely cause of the "Destination Host Unreachable" error?

A network technician is configuring OSPF on an AOS-CX switch. The technician wants to ensure that the switch advertises its directly connected VLAN 10 (192.168.10.0/24) and VLAN 20 (192.168.20.0/24) networks to its OSPF neighbors.
Which configuration snippet correctly enables OSPF and includes these two networks in the OSPF process?

What is the advantage of Multiple Spanning Tree Protocol (MSTP) over traditional STP?

A Network Operator is troubleshooting a connectivity issue where a host (10.10.10.50) cannot communicate with its default gateway (10.10.10.1). When the operator checks the ARP table on the gateway, the entry for 10.10.10.50 is "Incomplete".
What is the function of the Address Resolution Protocol (ARP) in this scenario?
