A Network Technician is troubleshooting an intermittent connectivity issue on a copper link. The technician suspects the problem might be related to the cable itself.
Which of the following represents a physical (Layer 1) problem?
- A . The switch port is in an STP blocking state.
- B . The device has the wrong default gateway configured.
- C . The cable is experiencing electromagnetic interference (EMI) from a nearby power source.
- D . The port is configured for the wrong VLAN.
A Network Technician is troubleshooting a 1Gbps copper link between two switches. The link is intermittently flapping (going up and down). The technician replaces the patch cable, but the problem persists. The cable run through the wall is approximately 80 meters.
Which of the following are potential Layer 1 causes for this intermittent issue? (Select all that apply.)
- A . A VLAN mismatch between the two switch ports.
- B . A source of strong electromagnetic interference (EMI) near the copper cable.
- C . The use of a UTP cable that is not rated for Gigabit speeds (e.g., Cat3 or Cat5).
- D . The cable having a split pair or other physical defect within the wall.
- E . Spanning Tree Protocol blocking the port.
Which of the statements describe valid AOS-CX secure management access concepts? (Select two)
- A . AAA accounting controls what you can do once you log in to the device.
- B . AAA services can be used in both the management VRF and the default VRF.
- C . Role-Based Access Control (RBAC) is based on a user’s group assignment.
- D . Advantages of using a RADIUS server include simplicity and faster authentication operations.
- E . An easy way to modify several users’ access is to modify the “operators” group.
Which are true about VSF stacking? (Select two)
- A . AOS-CX and AOS-S switches can be mixed in a VSF stack.
- B . CX 6200 Series and CX 6300 Series can be mixed in a VSF stack.
- C . Different models of CX 6200 Series can be mixed in a VSF stack.
- D . CX 8325 Series VSF stack supports up to 10 switches.
- E . The use of VSF is recommended in the access layer of a campus network.

Which access control method involves granting access to network resources based on the physical address of the Network Interface Card (NIC)?
- A . Port authentication
- B . Secure certificate verification
- C . Web authentication
- D . MAC authentication
What is the primary purpose of load balancing algorithms in LAGs?
- A . To increase the number of physical links in the LAG.
- B . To prioritize certain types of traffic over others.
- C . To distribute network traffic evenly across aggregated links.
- D . To establish redundant connections for fault tolerance.
A network is being designed to support voice, video, and data. A Solutions Architect needs to explain to the customer why simply having a high-bandwidth network (e.g., 10 Gbps links) is not enough to guarantee high-quality voice and video calls.
Which statements accurately describe the significance of QoS in this high-bandwidth converged network? (Select all that apply.)
- A . QoS is not needed because the high bandwidth prevents all forms of congestion.
- B . Even on high-bandwidth links, microbursts of traffic can cause momentary congestion, leading to jitter and packet loss for real-time applications.
- C . QoS ensures that even if the link is not fully saturated, delay-sensitive packets (like VoIP) are always processed and forwarded first by the switch.
- D . QoS is primarily for low-bandwidth networks (less than 1 Gbps).
- E . QoS allows the network to provide predictable and reliable service for critical applications, regardless of the other traffic on the network.
