When using the OSPF dynamic routing protocol on an Aruba CX switch, what must match on the neighboring devices to exchange routes?
Correct Answer:A
OSPF Open Shortest Path First. OSPF is a link-state routing protocol that uses a hierarchical structure to create a routing topology for IP networks. OSPF routers exchange routing information with their neighbors using Hello packets, which are sent periodically on each interface. To establish an adjacency Adjacency is a relationship formed between selected neighboring routers for the purpose of exchanging routing information., OSPF routers must agree on several parameters, including Hello timers, which specify how often Hello packets are sent on an interface. If the Hello timers do not match between neighboring routers, they will not form an adjacency and will not exchange routes.

You need to troubleshoot an Aruba CX 6200 4-node VSF stack switch that fails to boot correctly Select the option that allows you to access the switch and see the boot options available for OS images and ServiceOS.
Correct Answer:C
The option that allows you to access the switch and see the boot options available for OS images and ServiceOS is Conductor USB-C console port. This option provides direct access to ServiceOS, which is an operating system that runs on Aruba CX switches independently of AOS-CX Aruba Operating System CX (AOS-CX) is an operating system that runs on Aruba CX switches . ServiceOS provides low-level functions such as booting, firmware upgrades, password recovery, hardware diagnostics, switch stacking, and system recovery. ServiceOS can be accessed through one of two methods:
✑ Conductor USB-C console port: This method allows you to connect your PC or
laptop to the USB-C console port on any member switch in a VSF stack using a USB-C cable. This method provides direct access to ServiceOS without requiring any configuration or authentication on AOS-CX.
✑ AOS-CX CLI: This method allows you to access ServiceOS through AOS-CX CLI
using SSH or Telnet protocols. This method requires you to configure an IP address on AOS-CX and authenticate with your username and password.
To see the boot options available for OS images and ServiceOS, you need to access ServiceOS through Conductor USB-C console port and enter boot menu command at ServiceOS prompt.
The other options do not allow you to access the switch and see the boot options available for OS images and ServiceOS because:
✑ Member 2 RJ-45 console port: This option allows you to connect your PC or laptop
to the RJ-45 console port on any member switch in a VSF stack using an RJ-45 cable. This option provides direct access to AOS-CX CLI, not ServiceOS.
✑ Member 2 switch mgmt port: This option allows you to connect your PC or laptop
to the switch mgmt port on any member switch in a VSF stack using an Ethernet cable. This option provides indirect access to AOS-CX CLI through SSH or Telnet protocols, not ServiceOS.
✑ Conductor mgmt port using SSH: This option allows you to connect your PC or
laptop to the mgmt port on any member switch in a VSF stack using an Ethernet cable. This option provides indirect access to AOS-CX CLI through SSH protocol, not ServiceOS.
