What Are Two Actions Performed by a Cisco Switch? (Choose Two.) Essential IT Exam Test Guide on Cisco Switch Functions

Cisco certifications, like the CCNA, open doors to IT careers, and a clear understanding of Cisco switch functions is essential for passing these exams. This guide provides the test-ready answer to “What are two actions performed by a Cisco switch?” We’ll cover the correct answers, explain why they’re correct, and include additional insights to support your study efforts.

What Are Two Actions Performed by a Cisco Switch? (Choose Two)

A Cisco switch performs two essential actions: using source MAC addresses to build and maintain a MAC address table and forwarding frames based on the destination MAC address.

Explanation of Correct Actions

  1. Using Source MAC Addresses to Build and Maintain a MAC Address Table: Switches learn and store MAC addresses from incoming frames to keep an updated record of devices connected to the network.
  2. Forwarding Frames Based on the Destination MAC Address: The switch uses its MAC address table to direct frames to the correct destination, optimizing data flow and network performance.

These actions are fundamental to how Cisco switches operate within a network, allowing efficient traffic management and security.

Understanding Cisco Switch Operations

Cisco switches are key for managing traffic within local networks, especially at Layer 2 (data link layer). Here’s a breakdown of their core functions:

Core Functions of a Cisco Switch

Understanding these functions is crucial for Cisco certification, as they highlight the switch’s role in efficient and secure data transfer.

Access Switch vs. Core Switch

These distinctions can appear on exams, so it’s beneficial to understand how each type of switch operates within network architecture.

Cisco Access Switch: Core Functions Explained

What Is a Cisco Access Switch?

Cisco access switches serve as a link between end devices and the network infrastructure, connecting devices to ensure reliable communication.

Key Functions of a Cisco Access Switch

  1. Data Forwarding: Directs traffic to the correct destination, keeping data flow efficient.
  2. Traffic Filtering and VLAN Management: Uses VLANs (Virtual Local Area Networks) to segment traffic, improving security and reducing congestion.

Mastering these functions is valuable for Cisco exams, as it represents foundational knowledge in network management.
