Computer Memory and Storage

Standard CD-ROMs typically hold 650-700 MB of data, not 1000 MB. The 1000 MB figure would be closer to a DVD's capacity. This question tests knowledge of optical storage media specifications.

SCSI provides the fastest access to large files like video because it offers higher sustained data transfer rates and better performance with concurrent operations compared to IDE/EIDE. Optical drives have much slower read speeds than magnetic storage technologies. SCSI's architecture is optimized for high-throughput applications.

The Memory:Pages/sec counter measures hard page faults - when Windows must read from the disk rather than RAM. A value under 20 (roughly) is considered acceptable and indicates sufficient RAM. Values consistently above 20 suggest memory pressure. The option about 'coffee and relax' is the intended answer despite its informal tone, as it correctly indicates the system is healthy.

Tape backup has historically been the most common form of backup due to its low cost per gigabyte, portability, and reliability for long-term archival storage. Tape allows for high-capacity, sequential access storage ideal for backup operations. While disk and optical backups are used, tape dominated enterprise backup for decades.

A striped volume (RAID 0) spreads data across multiple disks in parallel, significantly improving read/write performance for applications that handle many small files. This is ideal for the described scenario where a custom application writes numerous temporary files. Spanned volumes (Option B) provide no performance benefit as they simply concatenate disk space. RAID 5 (Option C) offers redundancy but slower write performance due to parity calculations. Mount points (Option D) are for organization, not performance improvement.

Enabling disk quotas allows an administrator to monitor and limit disk space usage. To track usage without denying access, you enable the quotas but do not check the 'Deny disk space to users exceeding quota limit' option. Setting a warning level helps in tracking and notification.

Basic disks allow you to set aside space (partition space) to arrange data by creating primary and extended partitions. Option A is false because basic disks support limited volumes (4 primary partitions or 3 primary + 1 extended). Options C and D describe dynamic disk features (spanned volumes and fault-tolerant RAID).

When a volume spans multiple dynamic disks and the host server fails, you must move ALL disks containing parts of the volume to another Windows Server 2003 computer, then import the foreign disks. The Disk Management utility on the target computer will recognize the volume structure. Moving only some disks (D) or using disk recovery on the failed server (B) will not work.

Creating two sets of backups provides redundancy - if one backup set is damaged, corrupted, or lost, you have another set available for recovery. System State data alone (A) is insufficient for full disaster recovery. Recovery Console (C) helps repair systems but doesn't protect against data loss. Installation media (D) is needed but doesn't constitute a backup strategy.

Access time refers to the time delay between a request for data and the moment the data begins to be delivered. It specifically measures how long the storage device takes to locate and begin retrieving the requested file. Response time is broader (system reaction), Quick Time is a media format, not a storage metric.

DDR (Double Data Rate) is a memory technology that transfers data on both the rising and falling edges of the clock signal, effectively doubling the data transfer rate compared to older Single Data Rate (SDR) memory. This synchronous timing mechanism is why it's called Double Data Rate, and it became the standard for computer RAM in the early 2000s.

RAID stands for Redundant Array of Independent Disks (originally Inexpensive Disks). It combines multiple disk drives for data redundancy, performance improvement, or both, protecting against drive failure.

SATA stands for Serial ATA (Advanced Technology Attachment), not Tape Attachment. It's a computer bus interface for connecting storage devices like hard drives and SSDs to motherboards, replacing the older parallel ATA standard.
