Which of the following best describes the function of a network switch?
Broadcasts data to all connected devices on the network
Filters traffic using IP addresses at Layer 3
Sends transmissions from one port only to the destination port
Converts digital signals to analog for WAN communication
What is the purpose of VLAN tagging on a switch port?
To encrypt traffic on the port
To identify the port as a trunk link
To mark data packets with a VLAN ID
To set the port as an access port
Which IEEE protocol is used to prevent network loops by selecting a root bridge and blocking redundant paths?
802.1X
802.3
802.11ac
802.1D
Which of the following is a correct characteristic of a tagged switch port?
It strips VLAN identifiers from all incoming packets
It only accepts untagged packets
It is used to carry multiple VLANs
It belongs to only one VLAN
What technology allows multiple physical network interfaces to operate as a single logical interface for redundancy and performance?
VLAN trunking
Port mirroring
NIC teaming (Link Aggregation)
Inter-VLAN routing
You are troubleshooting why a device in VLAN 10 cannot communicate with a device in VLAN 20. Which of the following is the MOST likely cause?
The switch does not support PoE
The switch port is configured as untagged
Inter-VLAN routing has not been configured
Both devices have static IP addresses
Which switch feature prevents broadcast storms by eliminating loops in a Layer 2 network?
Maximum Transmission Unit (MTU)
Port Aggregation Protocol
Spanning Tree Protocol
Virtual LAN Routing
Which of the following would MOST likely cause a user to be unable to access network resources after being moved to a new cubicle?
Incorrect duplex setting
Incorrect VLAN assignment
Trunk port misconfiguration
MTU size mismatch
Which of the following is the PRIMARY purpose of the Spanning Tree Protocol (STP)?
To assign VLAN IDs to access ports
To create backup VLAN configurations
To prevent switching loops on a network
To improve IP routing performance
What does a switch do when it receives a frame with a destination MAC address not in its MAC address table?
Sends an ICMP unreachable message
Drops the frame immediately
Floods the frame out of all ports except the one it was received on
Forwards the frame only to trunk ports
A technician is configuring a trunk port between two switches. Which VLANs will be allowed across this link by default?
Only the native VLAN
All VLANs configured on the switch
Only VLAN 1
Only tagged VLANs
You observe excessive network traffic and suspect a switching loop. Which feature should be enabled to detect and eliminate the loop?
VLAN tagging
NIC teaming
Spanning Tree Protocol
Port mirroring
Which of the following port roles in STP is responsible for forwarding traffic toward the root bridge?
Root Port
Designated Port
Disabled Port
Backup Port
Which switch command would you MOST likely use to verify VLAN assignments and interface status?
show vlan brief
show ip route
ping
show running-config
Which feature allows multiple switches to appear as a single logical switch to connected devices?
Trunking
VLAN tagging
Switch stacking
Link aggregation
A technician discovers that two interfaces on different switches are configured with the same IP address. What is the MOST likely result?
No connectivity for any devices on the subnet
A spanning tree loop
IP address conflict and intermittent connectivity
Automatic failover between switches
True or False: Switches broadcast data to all devices connected to the network. -
true
false
What is a characteristic of an unmanaged switch?
It can be configured via a command-line interface.
It has multiple IP addresses assigned to it.
It provides plug-and-play capability with minimal configuration options.
It is capable of interpreting layer 3 data.
How can managed switches be configured?
Through physical buttons on the device
Via a command-line interface or a web-based management GUI
Only through a web-based management GUI
They cannot be configured
