In the network shown in the following graphic, Switch1 is a Layer 2 switch.
PC-A sends a frame to PC-C. Switch1 does not have a mapping entry for the MAC address of PC-C.
Which action does Switch1 take?
- A. Switch1 drops the frame and sends an error message back to PC-
- B. Switch1 sends an ARP request to obtain the MAC address of PC-
- C. Switch1 queries Switch2 for the MAC address of PC-C.
- D. Switch1 floods the frame out all active ports except port G0/1.
Answer: A
Explanation:
In a network, when a Layer 2 switch (like Switch1) receives a frame destined for a MAC address that is not in its MAC address table, it performs a flooding operation. This means the switch will send the frame out of all ports except the port on which the frame was received. This flooding ensures that if the destination device is connected to one of the other ports, it will receive the frame and respond, allowing the switch to learn its MAC address.
A). Switch1 queries Switch2 for the MAC address of PC-C: This does not happen in Layer 2 switches; they do not query other switches for MAC addresses.
A). Switch1 drops the frame and sends an error message back to PC-A: This is not the default behavior for unknown unicast frames.
D). Switch1 sends an ARP request to obtain the MAC address of PC-C: ARP is used by devices to map IP addresses to MAC addresses, not by switches to find unknown MAC addresses.
Thus, the correct answer is
B). Switch1 floods the frame out all active ports except port G0/1.

What is the purpose of assigning an IP address to the management VLAN interface on a Layer 2 switch?
- A. To enable access to the CLI on the switch through Telnet or SSH
- B. To enable the switch to resolve URLs for the attached the devices
- C. To enable the switch to act as a default gateway for the attached devices
- D. To enable the switch to provide DHCP services to other switches in the network
Answer: A
Explanation:
The primary purpose of assigning an IP address to the management VLAN interface on a Layer 2 switch is to facilitate remote management of the switch. By configuring an IP address on the management VLAN, network administrators can access the switch's Command Line Interface (CLI) remotely using protocols such as Telnet or Secure Shell (SSH). This allows for convenient configuration changes, monitoring, and troubleshooting without needing physical access to the switch1.
References :=
*Understanding the Management VLAN
*Cisco - VLAN Configuration Guide
*Remote Management of Switches
Assigning an IP address to the management VLAN interface (often the VLAN 1 interface by default) on a Layer 2 switch allows network administrators to remotely manage the switch using protocols such as Telnet or SSH. This IP address does not affect the switch's ability to route traffic between VLANs but provides a means to access and configure the switch through its Command Line Interface (CLI).
*A: The switch does not act as a default gateway; this is typically a function of a Layer 3 device like a router.
*B: The switch does not resolve URLs; this is typically a function of DNS servers.
*C: The switch can relay DHCP requests but does not typically provide DHCP services itself; this is usually done by a dedicated DHCP server or router.
Thus, the correct answer is D. To enable access to the CLI on the switch through Telnet or SSH.

During the data encapsulation process, which OSI layer adds a header that contains MAC addressing information and a trailer used for error checking?
- A. Network
- B. Transport
- C. Session
- D. Data Link
Answer: D
Explanation:
During the data encapsulation process, the Data Link layer of the OSI model is responsible for adding a header that contains MAC addressing information and a trailer used for error checking. The header typically includes the source and destination MAC addresses, while the trailer contains a Frame Check Sequence (FCS) which is used for error detection1.
The Data Link layer ensures that messages are delivered to the proper device on a LAN using hardware addresses and translates messages from the Network layer into bits for the Physical layer to transmit. It also controls how data is placed onto the medium and is received from the medium through the physical hardware.
