How does IPsec provide secure networking for applications within an organization?

1. A. It takes advantage of FTP to secure file transfers between nodes on the network.
2. B. It provides GRE tunnels to transmit traffic securely between network nodes.
3. C. It enables sets of security associations between peers.
4. D. It leverages TFTP providing secure file transfers among peers on the network.

Correct Answer: C
IPsec (Internet Protocol Security) is a protocol suite that provides secure communication over Internet Protocol (IP) networks. It achieves this by authenticating and encrypting each IP packet within a communication session. One of the key concepts in IPsec is the establishment of security associations (SAs) between peers. Security associations are the combination of algorithms and keys used to secure communication between two devices. They define the security parameters for the communication, including the encryption algorithm, integrity algorithm, and keying information. By establishing these security associations, IPsec ensures confidentiality, integrity, and authenticity of the data being transmitted between network nodes.

The entire contents of the MAC address table are shown. Sales-4 sends a data frame to Sales-1.

What does the switch do as it receives the frame from Sales-4?

1. A. Perform a lookup in the MAC address table and discard the frame due to a missing entry.
2. B. Insert the source MAC address and port into the forwarding table and forward the frame to Sales-1.
3. C. Map the Layer 2 MAC address to the Layer 3 IP address and forward the frame.
4. D. Flood the frame out of all ports except on the port where Sales-1 is connected.

What is the default behavior of a Layer 2 switch when a frame with an unknown destination MAC address is received?

1. A. The Layer 2 switch drops the received frame
2. B. The Layer 2 switch floods packets to all ports except the receiving port in the given VLAN.
3. C. The Layer 2 switch sends a copy of a packet to CPU for destination MAC address learning.
4. D. The Layer 2 switch forwards the packet and adds the destination MAC address to its MAC address table

Correct Answer: B
If the destination MAC address is not in the CAM table (unknown destination MAC address), the switch sends the frame out all other ports that are in the same VLAN as the received frame. This is called flooding. It does not flood the frame out the same port on which the frame was received.
