You have a file server named Server1 that runs Windows Server 2003 Service Pack (SP2). Server1 has a 10-gigabit network adapter and is connected to a 100-Mb switch. You replace the 100-Mb switch by using a 1-GB switch. You discover that copying files to Server1 over the network is slow. You need to reduce the amount of time it takes to copy files to Server1 over the network. Which connection type should you specify for the network adapter? ()
Your database is started by using the server parameter file (SPFILE). You issued this command to change the value of the LOG_BUFFER initialization parameter: ALTER SYSTEM SET LOG_BUFFER=24M SCOPE=BOTH; What would be the outcome of this command?()

you configure a new file server that runs windows server 2008. Users access shared files on the file server. Users report that they are unable to access the shared files.The TCP/IP properties for the file server are configured as shown in the following exhibit.You need to ensure that users are able to access the shared files. What should you do?()
The loss of the control file forced you to re/x7fcreate the control file. After re/x7fcreating it and opening the database, you find that some of the data files are named as MISSINGnnnnn, where nnnnn is a five/x7fdigit number starting with 0. What could be the possible reason?()
