102 The technical support clause of a Service Level Agreement (SLA) will typically include which of the following elements? (Choose all that apply.)Whether the provider will provide on-site, telephone, or online supportThe time service for responses to support calls, which specifies how quickly the provider must respond to requests for support.The percentage of time that the service is guaranteed to be availableThe amount of support that will be provided and the costs for additional support

103 After switching from a standard public switched telephone network (PSTN) telephone system to a Voice over Internet Protocol (VoIP) system, users are complaining of service interruptions and problems hearing callers at certain times of the day. After examining a network traffic audit and assessment report, you determine that traffic levels on the Internet connection are substantially higher during the first and last hours of the day, the same times when most of the users experienced problems. Which of the following solutions can provide more reliable VoIP service during peak usage times?Implement traffic shapingImplement load balancingUpgrade the Local Area Network (LAN) from Fast Ethernet to Gigabit EthernetReplace the router connecting the LAN to the Internet with a model that supports Simple Network Management Protocol (SNMP).
