What are the advantages for using power over Ethernet (POE)? What are the potential risks to users with using powered switch ports? How do you think the above risks can be avoided in the POE Plus standard? What primary differences are there between managed and unmanaged switches? In what instances would it make sense to use an unmanaged switch? What is the best means for mitigating the single points for failure on an Ethernet network? Give two business-use examples for each fiber types. When implementing SNMP for managed switches, what security planning principle must be considered?What are the advantages for using power over Ethernet (POE)?

Explanation / Answer
What are the advantages for using power over Ethernet (POE)?
The main advantage is the device doesn't need additional power supply.
What are the potential risks to users with using powered switch ports?
Human skin are very low in resistance. As minimum as 20mA current can have devastating effect on human. Powered ports can provide up to 25 watts of electricity. This can do a lethal damage to human.
How do you think the above risks can be avoided in the POE Plus standard?
In PoE Plus frist a relative low voltage is send to detect IEE signature to know it's safe to apply high voltages thus eliminating risk of exposing someone to electricity.
What primary differences are there between managed and unmanaged switches?
In managed switch all aspect of switch configuration can be controlled but in unmanaged switch you can control only predefined operations or configurations.
In what instances would it make sense to use an unmanaged switch?
Unmanaged switched are used in senarios like home network where high security is not required, where it's not feasible to hire or arrange skilled people who can configure a managable switch
What is the best means for mitigating the single points for failure on an Ethernet network?
Single point of faliour in ethernet network means such a node that if it goes down the entire network breaks down. To migrate the single points for failure means simply eleminating such points.
