Which three statements are true regarding the Network Time Protocol (NTP) in JUNOS platforms?()
A.MD5 authentication is supported.B.A client always synchronizes to a server even when the difference between the server clock and the local clock differs by a large amount.C.JUNOS software can provide a primary time reference.D.The boot-server configuration allows a router to synchronize its clock when it boots up, regardless of the offset between the NTP clock source and its internal clock.E.It is useful to correlate timestamps on log files and other events for troubleshooting and forensics.

考题
What is a characteristic of Network Time Protocol？（）A、NTP updates are sent in the timezone they are collected in，and the syslog server will adjust based on the input time.B、NTP authentication verifies the source，not the recipient.C、NTP authentication requires that the recipient has multiple strata clocks to ensure accuracy.D、Secure NTP can be configured to use SHA-1 hashing，since NTP is very insecure.E、A stratum 0 clock should be configured at the core of every network，so it can connect to an accuratetime source.

考题
Your Oracle10g database contains a table with a TIMESTAMP TO LOCAL TIME ZONE column. There are about two hundred column values for the column. You issued the following statement： SQL ALTER DATABASE SET TIME_ZONE =’Europe/London’； What will be the result of issuing the above statement？（）A、 The statement will be executed successfully， and a new time zone will be set for the database.B、 The statement will be executed successfully， but a new time zone will not be set for the database.C、 The statement will not be executed successfully because the SET TIME_ZONE clause can be used only with the ALTER SESSION statement.D、 The statement will not be executed successfully because the ALTER DATABASE SET TIME_ZONE statement is used only when the database contains no table with the TIMESTAMP TO LOCAL TIME ZONE column.
