220-1201 Exam Dumps - CompTIA A+ Core 1 Exam (2025)

A spam gateway filters unsolicited emails at the server level, significantly reducing spam before it reaches user inboxes.

Why Not A (Load balancer): Load balancers distribute traffic but don’t filter spam.

Why Not C (Mail forwarding): Forwarding doesn’t filter spam.

Why Not D (Proxy servers): Proxies control web traffic, not email filtering.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.10, email security controls​.

If a hard drive is heavily fragmented, file read/write operations can take significantly longer, causing slow backup speeds. Defragmenting the drive organizes the data for more efficient access.

Why Not A (Replace the hard drive's USB cable): A faulty cable would typically cause disconnections or errors, not just slower speeds.

Why Not C (Update the storage drivers): This might help if the issue is with system drivers, but the described symptoms point to a fragmentation issue.

Why Not D (Compress the files): Compression reduces file size but does not address the root cause of the slow backups.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 3.1, storage troubleshooting​.

An IP address beginning with 169.254.x.x is an APIPA address (Automatic Private IP Addressing). CompTIA A+ explains that APIPA is assigned automatically by Windows when the NIC cannot reach a DHCP server. This indicates the laptop requested an IP lease but never received one.

APIPA addresses allow only local subnet communication and cannot access the internet, because no default gateway, DNS, or valid subnet configuration is provided. Since all other employees can access the internet, the DHCP server is functioning generally, but it is not delivering an address to this specific laptop—possibly due to cable issues, Wi-Fi authentication failure, DHCP scope exhaustion, or NIC misconfiguration.

A subnet mask misconfiguration (A) would still show a normal IP, not APIPA. IPv6-only configuration (C) would not produce a 169.254 address. An outdated NIC driver (B) could cause network instability but does not directly generate APIPA.

Thus, the root cause is that the DHCP server did not assign an IP address.

Adocking stationconnects to a laptop’sproprietary port or USB-C/Thunderbolt, providing access tomultiple additional ports(USB, Ethernet, video, audio, etc.). It allows users to transform a laptop into a full desktop workstation.

Option A (NFC adapter):Used for short-range communication, not port expansion.

Option C (Port replicator):Similar to a dock but usually less powerful and often lacks charging or video output.

Option D (USB dongle):Adds a single function (like Wi-Fi or storage), not full port expansion.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.4: Given a scenario, configure settings and use cases for laptops and mobile devices.

===========

If a print spooler crashes specifically with one application and no issue occurs on other systems, the most likely root cause is a bug within that specific application. Restarting the spooler and reinstalling drivers resolves system-wide or hardware-related issues not app-specific failures. This indicates the application may be sending malformed print data.

CompTIA A+ teaches that the default gateway is required for any device to communicate with external networks such as the internet. Without a configured default gateway, the computer can communicate only with devices on the same local subnet explaining why the file server is reachable.

DNS and IPv6 settings are not the issue; without a gateway, external routing cannot occur. Flushing DNS affects hostname resolution, not routing. NetBIOS settings have no effect on internet connectivity.

Adding or correcting the default gateway (usually the router’s LAN IP, such as 192.168.1.1) will allow the PC to route traffic beyond its local network.

This aligns precisely with CompTIA’s troubleshooting steps for missing or incorrect gateway configuration.

An IDE hard drive uses a Molex connector for power. This 4-pin connector is a standard for older drives.

Why Not A (F type): F type connectors are used for coaxial cables in video and internet applications.

Why Not B (SC): SC connectors are for fiber optic cables.

Why Not D (Lightning): Lightning connectors are for Apple devices.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 3.1, cable types and connectors​.

Fiber optic connections provide the highest data transfer rates and symmetrical upload and download speeds. This makes fiber the ideal choice for applications requiring high-speed connectivity, such as video conferencing, large file transfers, and cloud-based workflows.
