Which is an example of a standard DHCP option?
A DNS server (the primary) for domainshop.co.uk is having problems
delegating authority and responsibility for the subdomain sales.domainshop.co.uk. Investigation reveals
that the delegation is not functioning. The current origin is domainshop.co.uk.
Given the lines from the domainshop.co.uk zone file:
sales. in ns centauri.domainshop.co.uk.
centauri.domainshop.co.uk in a 22.214.171.124
Which two errors are present? (Choose two.)
Which file contains the definitions for the default and vendor-specific DHCP options and symbols?
A DHCP server has an IP address of 126.96.36.199.
A DNS server has an IP address of 188.8.131.52.
The DNS server process is running in debug mode.
Given the debug output:
datagram from [184.108.40.206].32883, fd 26, len 44
req: nlookup(dhcp-pge-test.one.edu) id 19496 type=1 class=1
req: found ‘dhcp-pge-test.one.edu’ as ‘one.edu’ (cname=0)
ns_req: answer -> [220.127.116.11].32883 fd=26 id=19496 size=98 rc=3 datagram from [18.104.22.168].32884, fd 26, len 36 req: nlookup(dhcp-pge-test) id 19497 type=1 class=1 req: missed ‘dhcp-pge-test) as ” (cname=0)
What does the debug output indicate?
The IP address of an NTP stratum 4 server is 192.168.30.30. What entry in this server’s NTP configuration file indicates undisciplined local clock usage?
Given the portion of in.dhcpd output running in debug mode:
3cdbc114: There is no 22.214.171.124 dhcp-network table.
3cdbc114: Datagram received on network device: hme0.
Which two are executed on the DHCP server for the DHCP client to obtain an IP address? (Choose two.)
You have used the appropriate startup script in /etc/init.d to start the NTP
daemon. However, the NTP daemon does not start up. There is no error message. What is the reason for this?
Which two are causes of clock drift? (Choose two.)
Where does the NTP daemon send its error information by default?
A DNS server is configured as a secondary server and successfully synchronizes with the primary server when the secondary server is first started. A zone file on the primary server is updated but the secondary server fails to synchronize. The secondary server is rebooted but this fails to help. Which failure caused this problem?
