Ethernet Switching

Which of the following devices forwards data packets based on MAC addresses?

Router

Hub

Switch

Modem

Ethernet switches operate at which layer of the OSI model?

Physical Layer

Data link Layer

Network Layer

Transport Layer

Compared to hubs, switches offer:

Lower bandwidth

Increased collisions

Dedicated connections for devices

Slower data transfer rates

What is the term for a loop in a switched network that can cause a broadcast storm?

Bottleneck

Spanning Tree Protocol (STP)

Collision Domain

Bandwidth Throttling

Which type of switch port learns the MAC address of connected devices?

Trunk Port

Access Port

Console Port

Management Port

VLANs (Virtual LANs) in Ethernet switching allow for:

Increased network congestion

Improved network security and segmentation

Reduced overall network performance

Removal of the need for MAC addresses

Full-duplex communication in Ethernet switching means:

Data can only be sent in one direction at a time

Both devices can send and receive data simultaneously

Switches amplify signal strength

Packets are always broadcasted

What is the primary function of port security on an Ethernet switch?

To improve data transfer speeds

To limit the number of connected devices

To automatically configure switch settings

To increase the range of the network

Which of the following is NOT a common type of Ethernet frame used in switching?

Data Frame

Management Frame

Control Frame (Not commonly used in modern switching)

Jumbo Frame

What is the process of learning and updating the MAC address table on an Ethernet switch called?

Port Aggregation

Address Resolution Protocol (ARP)

Learning Bridge

Dynamic Host Configuration Protocol (DHCP)

Which switching technique uses content inspection to make forwarding decisions beyond just MAC addresses?

Port-based switching

VLAN switching

Content-Addressable Memory (CAM) switching

Layer 3 switching

What is the primary advantage of using static trunking over dynamic trunking protocols (DTP) when configuring switch trunk ports?

Improved security

Increased flexibility

Reduced configuration overhead

Automatic negotiation of trunk capabilities

What type of Spanning Tree Protocol (STP) is designed for rapid convergence after a network topology change?

Rapid Spanning Tree Protocol (RSTP)

Multiple Spanning Tree Protocol (MSTP)

Converged Enhanced Spanning Tree (CEPV2)

Shortest Path Bridging (SPB)

What is the main purpose of implementing Quality of Service (QoS) features on an Ethernet switch?

To increase the overall network bandwidth

To prioritize traffic for specific applications or devices

To eliminate network congestion completely

To simplify switch management tasks

When configuring port mirroring on an Ethernet switch, which port typically receives the mirrored traffic?

Management port

Any unused port

A designated sniffer port

The source port being mirrored

What is the benefit of using Link Aggregation Groups (LAGs) in Ethernet switching?

To create separate collision domains

To increase the bandwidth available between switches

To improve security between network segments

To simplify switch redundancy configurations

What is the difference between a source-learning and reverse ARP (RARP) on an Ethernet switch?

Source-learning builds the MAC address table, while RARP is used for IP address assignment.

RARP is faster than source-learning for building the MAC address table.

Source-learning works with static IP addresses, while RARP requires DHCP.

RARP is used for switch-to-switch communication, while source-learning is for device-to-switch.

What security feature on an Ethernet switch can be used to prevent unauthorized access to specific ports?

VLAN hopping

Port security

Link aggregation

Spanning Tree Protocol

What is the role of the Management Information Base (MIB) in Ethernet switch management?

To provide a graphical user interface for switch configuration

To define a standard for accessing and managing switch information

To encrypt switch configuration data

To automatically configure switch settings based on network topology

What is the main difference between cut-through and store-and-forward switching in terms of latency?

Cut-through offers higher latency due to minimal processing.

Store-and-forward provides lower latency by ensuring error-free packets.

Cut-through requires more processing power than store-and-forward.

Store-and-forward is not suitable for real-time applications.
