   An admin manages a fleet of access switches. Each switch has ports that connect to printers on VLAN 40 and ports that connect to scanners on VLAN 50. The admin wants to standardize the configuration across all switches and ensure that a change to the printer VLAN is applied everywhere consistently. What is the best approach?

   • AUse port groups to define the printer and scanner ports.
   • BConfigure each port manually on each switch.
   • CConfigure a trunk with native VLAN 40 on printer ports and native VLAN 50 on scanner ports.
   • DCreate two port profiles, one for printers and one for scanners, and apply them to the respective ports on each switch.

   An admin is planning a switch deployment. The switch has 32 ports of 400GbE. The design requires 64 downlink ports at 100GbE for servers and 8 uplink ports at 400GbE for spine connectivity. The admin must ensure the hardware supports this exact split. What is the most critical factor to verify before configuring the breakout?

   • AThe VLAN trunk configuration on the uplink ports.
   • BThe port profile applied to the uplink ports.
   • CThe switch's port breakout capability and the specific port ranges that support 4x100G breakout.
   • DThe MTU setting on the downlink ports.

   What does port breakout configuration on Dell SONiC allow an administrator to do?

   • ACombine multiple physical ports into a single logical link for redundancy
   • BEnable a physical port to operate at its maximum speed automatically
   • CAssign multiple IP addresses to a single physical interface
   • DSplit a single high-speed physical port into multiple lower-speed logical interfaces

   A data center admin is deploying a new rack of servers. Each server has a dual-port 25GbE NIC, and the top-of-rack switch has 100GbE ports. The admin wants to create a single logical interface configuration (speed, MTU, and admin state) that can be applied consistently to every downlink port after breakout. What should the admin do?

   • ACreate a port profile with the desired settings and apply it to each breakout port.
   • BConfigure each breakout port individually with the same settings via the CLI.
   • CApply the settings to the parent 100GbE port and expect them to inherit to the breakout children.
   • DUse a port group to aggregate the breakout ports into a single logical interface.

   An admin is planning a high-density server deployment. The switch has 32 ports of 100GbE. The admin needs 128 server connections at 25GbE. The admin also needs 8 uplink ports at 100GbE. The admin has verified that all 32 ports support 4x25G breakout. What is the maximum number of 25GbE downlink ports the admin can create while keeping 8 uplink ports at 100GbE?
