Which two statements are true?
On a system of your network, which is an NTP client, the output of the system administration command ntpq -p (standard Network Time Protocol query program) is:
remote refid st t when poll reach delay offset disp
===================================================================
*sun-roma02 sunital 4 m 26 64 377 0.98 0.340 1.50
Which two statements are true? (Choose two.)
Which variable must be modified?
A network administrator correctly configures a DHCP server that is serving JumpStart and non-JumpStart clients. One of the DHCP clients asks for an IP address. It does NOT ask for any other parameters such as subnet mask, router, and encapsulated vendor options. A variable must be modified in the /etc/default/dhcpagent file on the client to configure the DHCP client’s dhcpagent to request additional networking information from the DHCP server. Which variable must be modified?
Which three commands are useful in determining the cause of the messages?
The /var/adm/messages file on an NTP client shows many time reset (step) messages at regular intervals with the sign of the step alternating positive and negative with an amount that is nearly the same.
For example:
Jan 26 11:10:56 crater xntpd[6079]: time reset (step) 0.312899 s Jan 26 11:17:18 crater xntpd[6079]: time reset (step) -0.318915 s Jan 26 11:22:40 crater xntpd[6079]: time reset (step) 0.312903 s Jan 26 11:29:02 crater xntpd[6079]: time reset (step) -0.318887 s Jan 26 11:34:24 crater xntpd[6079]: time reset (step) 0.313149 s Jan 26 11:40:46 crater xntpd[6079]: time reset (step) -0.319057 s Jan 26 11:46:09 crater xntpd[6079]: time reset (step) 0.312988 s
Which three commands are useful in determining the cause of the messages? (Choose three.)
Which two tools will synchronize the two systems?
A network administrator configured an NTP server and an NTP client, but the client is refusing to synchronize with the server. The client and server clocks have drifted too much for the xntpd daemon to align them and for the NTP protocol to synchronize them. Which two tools will synchronize the two systems? (Choose two.)
Which file on the DHCP server needs to be updated?
While testing a new DHCP server, you discover that clients on the 192.168.120.0 network are being assigned an incorrect subnet mask. Which file on the DHCP server needs to be updated?
Which four are valid data types used to specify the kind of data that can be assigned as a value for the optio
The /etc/dhcp/inittab file contains information about the DHCP options passed from DHCP servers to clients. Which four are valid data types used to specify the kind of data that can be assigned as a value for the option? (Choose four.)
Which command was used to shut down the interface in such a way that a DHCPDISCOVER was NOT required?
On a DHCP client, the interface is down and configured with the IP address
0.0.0.0. After typing ifconfig hme0 dhcp start, you observe snoop output that does not include a
DHCPDISCOVER packet :
OLD-BROADCAST -> BROADCAST DHCP/BOOTP DHCPREQUEST
192.168.10.1 -> 192.168.10.10 DHCP/BOOTP DHCPACK
Which command was used to shut down the interface in such a way that a DHCPDISCOVER was NOT required?
Which file specifies the name resolution order?
The Solaris OS allows the resolution of name-to-address or address-to-name in many ways with different orders. Which file specifies the name resolution order?
Which can cause this to occur?
An address in your DHCP server is marked as being unuseable. Which can cause this to occur?
Which entry in this server’s NTP configuration file indicates undisciplined local clock usage?
The IP address of an NTP Stratum 4 server is 192.168.30.30. Which entry in this server’s NTP configuration file indicates undisciplined local clock usage?
