CompTIA 220-1201 - CompTIA A+ Certification Exam: Core 1 Certification Exam

A managed switch provides advanced features such as traffic monitoring and VLAN configuration,
allowing a technician to view network statistics for devices on the local subnet.
Why Not B (Router): A router connects different networks and directs traffic between them but does
not provide detailed subnet-level statistics. Why Not C (Access point): Access points provide wireless connectivity but lack traffic monitoring
features.
Why Not D (Firewall): A firewall filters traffic but is not used for monitoring detailed statistics on a
local subnet.

Virtual Desktop Infrastructure (VDI)hosts desktop environments on centralized servers.
Thisallowsrapid deployment and consistent configurationacross multiple users, minimizing manual
setup and easing IT management.
Option A:VDI still uses standard authentication methods.
Option B:Licensing can actually be more expensive due to virtualization software and backend
servers.
Option D:VDI centralizes the desktop environment — viruses would affect the virtual session, not be
"contained locally."
CompTIA A+ Core 1 Exam Objective Reference:
Objective 4.1: Compare and contrast cloud computing concepts.

NFC (Near-Field Communication)operates atvery short ranges — usually less than 4cm, and is ideal
for quick, secure transactions like contactless payments.Bluetoothsupportslonger ranges (up to 10
meters or 32 feet)and is suited for ongoing connections like wireless headsets or file transfers.
Option A:Bluetooth is faster for large file transfers.
Option B:NFC usesless power, not more.
Option C:NFC doesnotrequire pairing — Bluetooth does.
CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.5: Given a scenario, connect and configure accessories and ports of mobile devices.

A . Run the maintenance application:
Most modern printers include a built-in maintenance application that can calibrate the print heads
and correct alignment issues. Running this tool is the first step to address misalignment.
Incorrect Options:
B . Clean the rollers: Cleaning rollers is typically done to resolve paper feed or jamming issues, not
alignment problems.
C . Upgrade the firmware: While updating firmware is beneficial for performance improvements, it is
not the first step for fixing alignment.
D . Reinstall the drivers: Misaligned printing is usually hardware-related, not a driver issue.
Key Takeaway: The maintenance application should be run first to resolve alignment issues in a newly
installed printer.

An IP address starting with169.254.x.xis aself-assigned address(also calledAPIPA– Automatic Private
IP Addressing). It’s used when a client device cannot contact a DHCP server. This address allows
limited communication on the local network segment butno internet access.
Option A:DHCP reservations assign specific IPs from the DHCP server — they don’t result in APIPA.
Option B:Dynamic assignment from DHCP assigns valid IPs in the proper subnet, not 169.254.x.x.
Option D:Static IPs are manually set and would not fall in the 169.254.x.x range unless set incorrectly.
