To allow multiple users to print to networked printers:

Printer shares enable users to access printers shared on the network.

Print servers manage print jobs and provide centralized control of printing.

Why Not B (DHCP server): DHCP is unrelated to print management.

Why Not D (Printer subnet): Subnets group devices but don’t manage printing.

Why Not E (SMB configuration): SMB is for file sharing, not specifically print management.

Why Not F (Printer Wi-Fi settings): These settings are irrelevant since the printers use Ethernet.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 4.6, printer configuration​.

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.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 2.6: Given a scenario, configure and troubleshoot network connectivity.

A PoE injector is used to add power to an Ethernet cable, enabling the cable to deliver both power and data. This is crucial when connecting to PoE-enabled devices like IP cameras or wireless access points that are far from power outlets.

A valid public IP address must fall outside the private IP address ranges:

10.0.0.0 to 10.255.255.255

172.16.0.0 to 172.31.255.255

192.168.0.0 to 192.168.255.255

66.157.195.20 is outside these ranges, making it a public IP address.

Why Not A, C, D: These IPs fall within private IP address ranges.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.6, IP addressing​.

Atoner probe(also known as a tone generator and probe) is the best tool fortracing and identifying cablesin a patch panel or wall jack. The tone generator sends a signal through the wire, and the probe helps locate the cable by detecting the tone.

Option A (Crimper):Used to attach connectors (e.g., RJ-45), not for tracing cables.

Option B (Punchdown tool):Used to terminate cables into patch panels or keystone jacks.

Option C (Cable stripper):Used to remove insulation, not to trace cables.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 5.1: Identify basic cable types, their connectors, and their features.

Client virtualization involves installing an application on a server and enabling multiple users to run the application simultaneously via virtualized sessions. This eliminates the need for individual installations on local machines.

Why Not B (Software as a Service): SaaS delivers software over the internet and does not require local installations but is managed by a third party, not the organization itself.

Why Not C (Sandboxing): Sandboxing is for isolating applications for security testing, not for concurrent user access.

Why Not D (Embedded software): Embedded software is installed on hardware devices, not shared across multiple users.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 4.2, virtualization concepts​.

DHCP (Dynamic Host Configuration Protocol) is the service used to automatically assign IP addresses to network hosts. It dynamically manages the distribution of IP addresses and configuration details (like subnet mask, gateway, and DNS servers), ensuring no two devices are assigned the same address on the network.

Option B (DNS): Incorrect. DNS translates domain names into IP addresses but does not assign them.

Option C (LDAP): Incorrect. LDAP is a protocol used for accessing and maintaining directory services, such as user information and permissions.

Option D (SMTP): Incorrect. SMTP is used for sending and receiving email, not for IP address assignment.

A managed switch allows an administrator to enable or disable individual ports as part of network security and management. If a port on a managed switch has been disabled, the device connected to that port will lose connectivity, which matches the scenario described.

A Storage Area Network (SAN) is primarily used for data archiving and large-scale storage. SANs provide high-speed, block-level storage for enterprise environments.

Why Not A (PAN): Personal Area Networks are for connecting personal devices like phones and smartwatches.

Why Not B (MAN): Metropolitan Area Networks are for city-wide data communication, not storage.

Why Not D (LAN): Local Area Networks are for general connectivity, not dedicated storage.

Why Not WAN: Wide Area Networks are for connecting geographically dispersed networks, not storage.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.7, network types and purposes​.

Application virtualization allows legacy software to run in a virtualized environment while the operating system remains current. It isolates the application from the OS, ensuring compatibility without downgrading the OS.

Why Not A (Shared resources): This relates to resource sharing, not application compatibility.

Why Not B (System sandbox): Sandboxes isolate applications for security testing, not compatibility.

Why Not C (Test development): Test environments are used for development, not running legacy applications.
