Which two statements are correct regarding Layer 2 network switches? (Choose two.)
Layer 2 network switches flood broadcast traffic to all ports except the port where the broadcast was received. Additionally, switches are susceptible to traffic loops, which can cause broadcast storms and network instability if loop prevention protocols like Spanning Tree Protocol (STP) are not in place. Each port on a switch represents its own collision domain rather than creating a single collision domain for the entire switch.
What are two attributes of the UDP protocol? (Choose two.)
UDP is a best-effort protocol that does not guarantee the delivery of packets and does not perform error checking or correction, making it a best-effort service. Additionally, UDP is connectionless, meaning that it does not establish a connection before transmitting data, which allows for faster communication at the cost of reliability.

You are unable to remotely access your Juniper device using the CLI.
Referring to the exhibit, which command would you add to the existing configuration to enable remote CLI access?
To enable remote CLI access on a Juniper device, you need to allow the device to receive SSH connections. The configuration shown in the exhibit does not include the necessary SSH service configuration. Adding 'set system services ssh' will enable SSH access, allowing remote CLI connections to the device.
You are trying to diagnose packet loss at interface ge-0/0/3.
In this scenario, which command would help you view error statistics in real time?
The correct command to view error statistics in real time on a specific interface is 'monitor interface ge-0/0/3'. This command allows you to see ongoing and real-time statistics for the specified interface, which is useful for diagnosing issues such as packet loss.
Which prompt indicates that you are using configuration mode?
The prompt '#' typically indicates that you are in configuration mode in many network devices and systems. This is a common convention across various types of equipment and platforms.
