A network admin is analyzing syslog messages from a router to determine the cause of a security breach. The admin notices that the logs do not include the exact time of the events. What should the admin do to ensure future logs have accurate timestamps?

Use 'logging buffered' to store logs locally

Enable 'service timestamps log datetime'

Set the time zone with 'clock timezone'

A network engineer is managing logs from multiple routers. The engineer wants to ensure that logs are not lost during a reboot and that they can be reviewed after a crash. Which two configurations should be implemented? (Select all that apply.)

Configure 'logging persistent' to store logs in flash

Configure 'logging console' to display logs on the console

Configure 'logging buffered 4096' to store logs in RAM

Configure 'logging synchronous' to prevent console messages from interrupting input

Configure 'logging host' to send logs to a remote server

A network admin is comparing SNMPv2c and SNMPv3 for a new monitoring deployment. The admin needs to ensure that monitoring data is encrypted and that only authorized users can access it. Which SNMP version and configuration should be used?

SNMPv2c with a complex community string

A network engineer is planning to migrate from SNMPv2c to SNMPv3 for security reasons. The engineer wants to minimize downtime and ensure that the NMS can still monitor devices during the transition. Which approach is best?

Configure SNMPv3 on the NMS first, then on the devices

Use SNMPv3 only on critical devices and SNMPv2c on others

Configure SNMPv3 on all devices and keep SNMPv2c temporarily

Configure SNMPv3 on all devices and immediately remove SNMPv2c

A network admin is troubleshooting why SNMP GET requests for a specific OID return 'no such name' on a router. The router is configured with SNMPv2c and the community string 'public' with read-only access. What is the most likely cause?

The OID is not supported by the device

The community string is incorrect

The NMS is using the wrong SNMP version
