You need to verify network connectivity for a host. Which tool should you use?
A. ping
B. net use
C. sfc
D. dism
A. ping
The ping command is used to verify basic network connectivity to hosts, by sending a packet to the destination host in which it responds. The net use command is used to map network drives. The sfc command is used to scan the filesystem for corrupted system files. The dismcommand is an image-servicing tool used to add features to an operating system.
Which of the following utilities is used to update Group Policy settings and replaces some of the functionality that previously existed with secedit?
A. clobber
B. gpupdate
C. consolidate
D. extract
B. gpupdate
The gpupdate utility is used to update Group Policy from the command line. The clobber command is a Linux command. The extractcommand is used to extract files from .cab files.
Which of the following commands can be used to configure a remote connection?
A. regedit
B. mstsc
C. regsvr32
D. spl
B. mstsc
The mstsc (Microsoft Terminal Services Client) command is used to configure and connect to remote connections over the network. The regedit command is used to edit the Registry, and regsvr32 is used to register DDLs. Spl is not a command.
Which type of resources do you configure in Device Manager?
A. Hardware
B. Files and folders
C. Applications
D. Memory
A. Hardware
Hardware resources are configured in the Device Manager console. Files and folders and applications are configured in the operating system GUI. Memory is configured in System Properties.
Which of the following utilities will rearrange the files on your hard disk to occupy contiguous chunks of space?
A. Disk Defragmenter
B. Windows File Explorer
C. Scandisk
D. Windows Backup
A. Disk Defragmenter
Disk Defragmenter will rearrange blocks of files on a hard drive to create contiguous files and space. Windows File Explorer is used to navigate the filesystem. Scandisk is not a command. Windows Backup allows for file backups.
Which of the following filesystems is a proprietary filesystem created by Microsoft for use with large flash drives?
A. GPT
B. NFS
C. ext3
D. exFAT
D. exFAT
The exFAT filesystem is a Microsoft proprietary filesystem created for large flash drives. GPT is a partition table type; NFS is a network filesystem used with Linux/UNIX; and ext3 is a filesystem used with Linux.
In Windows, which of the following is the filesystem of choice for CD media?
A. NTFS
B. EFS
C. FAT32
D. CDFS
D. CDFS
The CDFS filesystem is used for CD media. NTFS is the native filesystem for the Windows operating system. FAT32 is a filesystem that was popular with Windows 9x operating systems. EFS is a technology that encrypts files.
Virtual memory is configured through which system tool?
A. Taskbar
B. System Properties
C. Memory Manager
D. Virtual Configuration
B. System Properties
Virtual memory is configured in the System Properties applet. The taskbar is an element of the desktop; the memory manager is a process in the operating system for memory management; and virtual configuration is an invalid answer.
You believe that your system files are corrupted in Windows. You run the System File Checker. Which command should you run in order to make the System File Checker automatically repair your system files?
A. sfc /recover
B. sfc /repair
C. sfc /verifyfile
D. sfc /scannow
D. sfc /scannow
The System File Checker (sfc) will scan for and fix missing or corrupted operating systems files. The command used to initiate an immediate scan is sfc /scannow. SFC /recover and SFC /repair are not valid options. SFC /verifyfile will check a single file, but the path must be specified.
Which of the following replaces the MBR in 64-bit versions of the Windows operating system?
A. LILO
B. NFS
C. GPT
D. GRUB
C. GPT
GUID Partition Tables (GPT) allocate a 64-bit logical block addressing entry to partition tables to accommodate larger drives. GPT has rapidly replaced the MBR style partition tables. LILO and GRUB are boot managers for Linux. NFS is a network filesystem used with Linux/UNIX operating systems.
Which of the following partitions is specifically the partition from which the operating system boots?
A. Primary partition
B. Extended partition
C. Dynamic partition
D. Logical partition
A. Primary partition
The operating system must boot from an active primary partition if MBR style partitioning is used. Extended partitions are used to contain logical partitions. There is no such thing as a dynamic partition.
Which utility can be used to schedule a remote shutdown?
A. taskmgr
B. kill
C. shutdown
D. netstat
C. shutdown
The shutdown utility can be used to schedule a remote shutdown—for example, shutdown /t 60 /m \computer. The taskmgr utility is used to view tasks; kill is used to kill processes; and netstat is used view network statistics and activity.
Which of the following Registry hives contains information about the computer’s hardware?
A. HKEY_CURRENT_MACHINE
B. HKEY_LOCAL_MACHINE
C. HKEY_MACHINE
D. HKEY_RESOURCES
B. HKEY_LOCAL_MACHINE
The HKEY_LOCAL_MACHINE Registry hive contains information about the computer’s hardware. It is also known as HKLM. HKEY_CURRENT_MACHINE and HKEY_MACHINE are not valid Registry hives. HKEY_RESOURCES was used with Windows 9x operating systems but is no longer used.
Which tool can be used to verify that a display driver is signed?
A. dxdiag
B. msinfo
C. msconfig
D. msinfo32
A. dxdiag
The dxdiag tool is used to verify that display drivers are signed properly by the vendor. Msinfo is not a utility. Msconfig is used to configure service and program startup. Msinfo32 allows you to see all attached devices and the operating system environment.
Which of the following switches can be used with robocopy to mirror a complete directory tree?
A. /s
B. /mir
C. /cdt
D. /ah
B. /mir
The robocopy command used with the /mir switch will mirror a directory tree file structure. The /s switch can be used to copy subdirectories, but not empty ones. The /cdt switch and the /ah switch are not valid for robocopy.
