What are two advantages of implementing a controller-based architecture instead of traditional network architecture? (Choose two.)
Answer: DE
The two advantages of implementing a controller-based architecture instead of traditional network architecture are: D. It enables configuration task automation. E. It provides increased scalability and management options. Controller-based architectures use a central controller to manage and configure network devices. This allows network administrators to automate configuration tasks, which can save time and reduce errors. Controller-based architectures also provide increased scalability and management options, as the controller can be used to manage a large number of network devices.

SIMULATION - Guidelines - This is a lab item in which tasks will be performed on virtual devices • Refer to the Tasks tab to view the tasks for this lab item. • Refer to the Topology tab to access the device console(s) and perform the tasks. • Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window. • All necessary preconfigurations have been applied. • Do not change the enable password or hostname for any device. • Save your configurations to NVRAM before moving to the next item. • Click Next at the bottom of the screen to submit this lab and move to the next question. • When Next is clicked the lab closes and cannot be reopened. Topology -
Tasks - All physical cabling is in place and verified. Connectivity between all four switches must be established and operational. All ports are pre-configured as 802.1q trunks. 1. Configure both SW-1 and SW-2 ports e0/1 and e0/2 to permit only the allowed VLANs 2. Configure both SW-3 and SW-4 ports e0/2 to permit only the allowed VLANs 3. Configure both SW-1 and SW-2 e0/1 ports to send and receive untagged traffic over VLAN 99 4. Configure both SW-3 and SW-4 ports e0/0 and e0/1 for link aggregation using the industry standard protocol. All ports must immediately negotiate the link aggregation 5. Permit only the allowed VLANs on the new link
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
