1 After starting work as the network administrator of Wingtip Toys, you discover that all of the switches in the company's datacenter have support for remote management, with built-in Simple Network Management Protocol (SNMP) agents in each port. Which of the following tasks must you perform to be able to gather information from the agents on those switches and display it on a central console? (Choose all that apply.)Install the network management software on a network computer.Install a Management Information Base (MIB) on each of the switches.Install an agent on the console computer.Install an MIB on the console computer.Purchase a network management product.
2 Which versions of the Simple Network Management Protocol (SNMP) do not include any security protection other than a cleartext community string? (Choose all that apply.)SNMPv1SNMPv2SNMPv2cSNMPv3
3 Which of the following statements about the Simple Network Management Protocol (SNMP) are not true? (Choose all that apply.)To effectively monitor a network using SNMP, you must be sure that all of the equipment you purchase when designing and building your network supports the protocol.SNMP is not only the name of a protocol, it is also the name of a network management product.SNMPv1 and SNMPv2 rely on a community string as their only means of security.Most of the network management products on the market today support SNMPv3.
