CompTIA 220-1201 Exam With Confidence Using Practice Dumps

CompTIA A+ details that an Automatic Document Feeder (ADF) allows multi-page documents to be scanned automatically without manually placing each sheet on the flatbed. This drastically increases scanning efficiency for large documents.

Flatbed scanners require manual placement for every page. Duplexing scans both sides of a page but does not feed multiple sheets by itself. Orientation configuration only affects image alignment.

The ADF is explicitly highlighted in the A+ study guide as the primary feature used in business environments when scanning high-volume documents efficiently.

Thus, the ADF is the correct solution because it automates page feeding and dramatically reduces scanning time, especially for hundreds of pages.

The correct answer is D. RAID 10 (also called RAID 1+0).

According to CompTIA A+ Core 1 220-1201 objectives under Storage:

RAID 10 combines the mirroring of RAID 1 with the striping of RAID 0. This provides both high data availability (because each drive has a mirror) and improved performance (because data is striped across multiple disks).

RAID 10 requires a minimum of four drives and is suitable for servers that handle high I/O workloads while maintaining redundancy.

Why the other options are incorrect:

A. RAID 1: Provides mirroring for redundancy but does not improve performance as effectively as RAID 10.

B. RAID 0: Provides striping for performance but has no redundancy; a single drive failure results in data loss.

C. RAID 5: Provides parity and can tolerate one drive failure with decent read performance, but write performance is lower than RAID 10 and rebuilds can impact system performance under heavy load.

An MX, or Mail Exchanger, record is a type of DNS resource record. It identifies the mail server responsible for accepting email for a particular domain. Consequently, an MX record is created or modified in the domain’s DNS zone , which is hosted on a DNS server.

Although the MX record points to a mail server, the record itself is configured through DNS. The mail server is the destination identified by the record, not the service in which the DNS record is stored.

A proxy server intermediates network requests, commonly for filtering, caching, or privacy.

A mail server sends, receives, and stores email, but DNS tells other systems how to locate it.

A print server manages printers and print jobs.

CompTIA objective 2.4 specifically includes DNS record types such as A, AAAA, CNAME, MX, and TXT. Microsoft also defines an MX record as a DNS resource record that identifies a domain’s mail server.
