A network administrator is designing a new network and needs to ensure that management traffic to switches is isolated from user traffic. Which VLAN type should be used for switch management?

A dedicated management VLAN, such as VLAN 99.

What is the primary purpose of a MAC address in a local network?

To uniquely identify a network interface on a local network segment

To identify a device's location on the internet

To provide a logical address that can change based on the network

To encrypt data transmitted between two devices

A network engineer is analyzing a packet capture and sees a frame with destination MAC address FF:FF:FF:FF:FF:FF. What is the purpose of this frame?

It is an invalid frame that will be dropped by switches.

It is a multicast frame sent to a group of devices.

It is a unicast frame sent to a specific device.

It is a broadcast frame sent to all devices on the local network.

A network engineer is troubleshooting intermittent connectivity on a LAN. The engineer notices that the switch's MAC address table is constantly changing, with the same MAC address appearing on different ports at different times. What is the most likely cause of this issue?

The switch is running out of MAC address table space.

The switch is configured with multiple VLANs.

The switch is receiving frames from a rogue DHCP server.

A network loop is causing frames to be flooded and MAC addresses to be learned on multiple ports.
