You want to redirect log messages from a router to a Syslog server. The IP address of the Syslog server is 172.17.8.5. You want only serious log messages with a severity level of emergency, alert, critical, error, or warning to be redirected. Notifications and informational messages as well as debug messages should not be redirected. You just entered the logging on command. Which other commands must be used to accomplish this task? (Select two. Both responses are part of the complete solution.) a. logging trap 4 b. logging server 172.17.8.5 c. logging severity warning d. logging severity 4 e. logging host 172.17.8.5 f. show logging
logging trap 4 logging host 172.17.8.5
Which SNMPv3 security level requires authentication with a username, but does not implement encryption? a. noAuthnoPriv b. authNoPriv c. authPriv d. Community Name
noAuthnoPriv
You check the time on a router and find that it is behind by several minutes. To fix this issue, you decide to configure NTP on the router to get time from a Stratum 2 time provider on the internet with a hostname of 0.pool.ntp.org. Which command should you use? a. ntp server 0.pool.ntp.org b. ntp master 0.pool.ntp.org c. feature ntp 0.pool.ntp.org d. ntp status
ntp server 0.pool.ntp.org
You check the time on a router and find that it is out of sync with the time on the other routers and switches in your network. To fix this issue, you decide to configure NTP on the router to get time from an internal authoritative (master) NTP server with an IP address of 172.17.8.254. Which command should you use? a. ntp status b. ntp server 172.17.8.254 c. ntp master 172.17.8.254 d. feature ntp 172.17.8.254
ntp server 172.17.8.254
Currently, all of the routers in your network are configured to use NTP to synchronize time with a public Stratum 2 time provider on the internet. To reduce redundant network traffic, you decide to configure one internal router as an authoritative NTP time provider with a stratum value of 5 and then configure all other routers to synchronize time with it. This router has an IP address of 172.17.8.254 assigned. Which commands should you use? (Select two. Each response is a part of the complete solution.) a. ntp server 172.17.8.254 on all routers except the time provider. b. ntp master 5 172.17.8.254 on all routers except the time provider. c. ntp master on the NTP time provider router. d. ntp server 172.17.8.254 on the NTP time provider router. e. ntp master 5 on the NTP time provider router.
ntp server 172.17.8.254 on all routers except the time provider. ntp master 5 on the NTP time provider router.
You need to verify that time is synchronized on a router. Which commands could you use to do this? (Select two. Each response is a complete solution.) feature ntp clock summer-time <zone> ntp server <address> show ntp associations show ntp status
show ntp associations show ntp status
