Ethernet Technology Quiz

Virtual switches

What are modular switches?

What is autonegotiation used for in unmanaged switches?

What is the primary function of MAC (Media Access Control) addressing in Ethernet technology?

• To identify the sender and recipient of the data.

• To convert data frames into electrical or optical signals.

• To forward data frames to the appropriate device.

• To adjust configuration settings on network adapters.

• To perform routing functions at OSI Layer 3.

What does the CLI tab in Cisco Packet Tracer simulate?

• Direct cable (console) connection to a network device

• User mode

• Privileged mode

• VLAN configuration mode

• Global configuration mode

What distinguishes managed switches from unmanaged switches in a network environment?

• Managed switches enable monitoring and configuration changes for each port, while unmanaged switches do not.

• Managed switches perform routing functions at OSI Layer 3, while unmanaged switches do not.

• Managed switches use autonegotiation to determine data rate, while unmanaged switches do not.

• Managed switches are software-only switches instantiated inside VM hosting environments.

• Managed switches are connected to one another via a backplane cable interface to form a single logical switch, while unmanaged switches are not.

IP address subscription form?

• 4 bytes (32 bits)

• 2 bytes (16 bits)

• 3 bytes (24 bits)

• 5 bytes (40 bits)

• 6 bytes (48 bits)

What are the main features of VLANs (Virtual Local Area Networks) in networking?

• Segmentation of broadcast domains, enhanced security, and simplified network management.

• Increased bandwidth, reduced latency, and improved reliability.

• Dynamic IP addressing, automatic failover, and load balancing.

• Integration with public cloud services, encryption of data in transit, and multi-factor authentication.

• Physical isolation of network devices, manual configuration of IP addresses, and centralized logging.

Managed switches

• let a user adjust each port on the switch.

• are software-only switches instantiated inside VM hosting environments.

• connect LANs. In addition to doing MAC-based Layer 2 switching, they perform routing functions at OSI Layer 3 (network layer), directing traffic based on the IP address in each packet.

• enable Ethernet devices to pass data automatically using autonegotiation, which determines parameters such as data rate.

• can be configured to enable more control over data transmissions, but they have more limitations compared to managed switches.

What is the primary function of a DHCP (Dynamic Host Configuration Protocol) server in a network?

• By dynamically assigning IP addresses to devices when they join the network. (correct option)

• By statically assigning IP addresses to devices during network configuration.

• By encrypting data packets transmitted over the network.

• By managing routing tables and traffic flow between subnets.

• By monitoring network performance and generating usage reports.
