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.

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
Answer:
What is the purpose of the service-set identifier?
- A. It identifies the wireless network to which an application must connect.
- B. It identifies the wired network to which a network device is connected.
- C. It identifies the wired network to which a user device is connected.
- D. It identifies a wireless network for a mobile device to connect.
What are two advantages of implementing a controller-based architecture instead of traditional network architecture? (Choose two.)
- A. It allows for seamless connectivity to virtual machines.
- B. It increases security against denial-of-service attacks.
- C. It supports complex and high-scale IP addressing schemes.
- D. It enables configuration task automation.
- E. It provides increased scalability and management options.
Which component controls and distributes physical resources for each virtual machine?
- A. hypervisor
- B. OS
- C. CPU
- D. physical enclosure
Why is TCP desired over UDP for applications that require extensive error checking, such as HTTPS?
- A. UDP uses sequencing data for packets to arrive in order, and TCP offers the capability to receive packets in random order.
- B. UDP uses flow control mechanisms for the delivery of packets, and TCP uses congestion control for efficient packet delivery.
- C. UDP reliably guarantees delivery of all packets, and TCP drops packets under heavy load.
- D. UDP operates without acknowledgments, and TCP sends an acknowledgment for every packet received.
What is a benefit of a point-to-point leased line?
- A. low cost
- B. full-mesh capability
- C. simplicity of configuration
- D. flexibility of design

Which cable type must be used to interconnect one switch using 1000 BASE-SX GBIC modules and another switch using 1000 BASE-SX SFP modules?
- A. LC to SC
- B. SC to SC
- C. LC to LC
- D. SC to ST

What is a function of Layer 3 switches?
- A. They route traffic between devices in different VLANs.
- B. They transmit broadcast traffic when operating in Layer 3 mode exclusively.
- C. They move frames between endpoints limited to IP addresses.
- D. They forward Ethernet frames between VLANs using only MAC addresses,
