• 802.11ac with 3 spatial streams and a 20MHz bandwidth

• 802.11ac with 3 spatial streams and a 40MHz bandwidth

• 802.11ac with 4 spatial streams and a 160MHz bandwidth

Which of the following protocols is used to encapsulate other network layer protocols such as multicast and IPX over WAN connections?

Jane, a network technician, has just installed a fiber switch in a datacenter. To run the fiber cabling, Jane plans the cable route over the top of the rack using the cable trays, down to the switch, coiling up any excess cable. As Jane configures the switch, she notices several messages in the logging buffer stating the receive signal of the SFP is too weak. What is MOST likely the cause of the errors in the logging buffer?

• Bend radius exceeded

• Fiber cable mismatch

• Fiber type mismatch

• Bad fiber switch

A network administrator has a monitoring system in place that is currently polling hundreds of network devices at regular intervals. The continuous polling is causing high CPU utilization on the server. Which of the following tasks should the administrator perform to resolve the CPU issue while maintaining full monitoring capabilities?

• Remove SNMP polling and configure SNMP traps on each network device

• Remove SNMP polling and implement snmpwalk on each network device

• Upgrade SNMP to the latest version to mitigate vulnerabilities

• Modify SNMP polling to poll only during business hours

• MT-RJ

• Media converter

• Cable certifier

• OTDR
