Mobile Application Management (MAM) enforces policies restricting access to apps and services based on location, ensuring security at external sites.

Why Not A (MOW): "Mobile Only Workplace" (MOW) is not a recognized term in this context.

Why Not B (MAN): Metropolitan Area Network (MAN) is unrelated to mobile device policies.

Why Not C (MFA): Multi-Factor Authentication secures user accounts but does not enforce app restrictions.

An internal cloud platform operated exclusively for a single organization is a private cloud, providing dedicated resources and enhanced control.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Cloud models:

“A private cloud is provisioned for exclusive use by a single organization, typically managed internally or by a third party, and may be hosted on-premises.”

Infrastructure as a Service (IaaS) provides the foundational computing components: virtualized hardware, storage, networking, and hypervisor resources. CompTIA A+ explains that customers using IaaS are responsible for installing and maintaining:

The operating system

Applications

Patches, updates, and configurations

This model gives organizations maximum flexibility because they can build custom server environments without purchasing physical hardware.

In contrast:

SaaS (A) provides fully managed applications—users do not manage OS or software.

PaaS (B) provides a development platform and tools but does not allow OS management.

XaaS (D) is a broad term meaning “anything as a service,” not a specific model.

Thus, IaaS is the only model where OS-level control remains with the customer.

Whenever a CPU heat sink is removed or replaced, thermal paste must be reapplied. Thermal paste fills microscopic gaps between the CPU heat spreader and the heat sink, ensuring efficient heat transfer. Without it, there is a significant air gap, which acts as an insulator, causing CPU temperatures to rise dramatically even under light load. CompTIA A+ stresses thermal compound application as a key step in CPU cooling installation.

The scenario indicates that temperatures increased drastically after upgrading to a better heat sink. A higher-performing heat sink should improve temperatures, not worsen them—unless a critical installation step was missed. Missing thermal paste is the most common cause of this symptom and easily explains the sudden overheating.

Decreased CPU voltage would lower temperatures, not raise them. Higher fan RPM increases cooling efficiency, not reduces it. Airflow interruption is possible but less likely in a simple heat sink upgrade scenario unless the technician installed the CPU cooler incorrectly; however, the most direct and common cause described by CompTIA is missing thermal paste.

Thus, D is the correct answer.

A corporate-provided email client is designed to integrate with enterprise services such as shared mailboxes, MDM policies, and enterprise authentication. CompTIA A+ states that corporate clients support additional management features, secure authentication protocols (such as OAuth or Kerberos), and policy-enforced access control essential for accessing shared or departmental mailboxes.

Open-source clients (Option A) may lack compatibility with enterprise environments. Built-in smartphone clients (Option B) often don’t support complex mailbox structures such as shared mailboxes. Employee-preferred apps (Option D) are discouraged because they may not meet security requirements.

Corporate clients ensure full compatibility with organizational mail servers, shared folders, calendars, and enterprise security features, making corporate email clients the correct choice according to CompTIA’s mobile device email configuration standards.

Port 23 is used by Telnet, an unencrypted remote connection protocol that poses significant security risks. Disabling Telnet and using secure alternatives like SSH (port 22) is best practice.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.1 – Common ports and protocols:

"Port 23 (Telnet) provides unencrypted remote access and should be disabled to increase security. Use SSH (port 22) for secure remote connections."

A hybrid cloud combines private infrastructure (on-premises, self-operated data centers) with public cloud services, providing flexibility and scalability.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Cloud concepts:

“A hybrid cloud model integrates private and public cloud infrastructure to allow applications and data to be shared between them.”

A network switch operates at Layer 2 (Data Link Layer) of the OSI model and forwards traffic using MAC addresses. CompTIA A+ teaches that switches maintain a MAC address table, learning which devices reside on each port. When a frame arrives, the switch checks the destination MAC address and forwards it only to the appropriate port, reducing unnecessary traffic and improving performance.

Routers, on the other hand, operate at Layer 3 and forward traffic based on IP addresses, not MAC addresses. Firewalls inspect traffic for security policies and operate across multiple OSI layers but do not perform MAC-based forwarding. A gateway is a broad term that generally refers to a device connecting different networks or protocols, typically involving routing, not MAC-based switching.

Thus, the device specifically responsible for forwarding frames based on MAC address lookup is the switch.

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.

2.4GHz Wi-Fi signals have better penetration through walls and other obstacles compared to 5GHz and 6GHz. Lower frequency waves (like 2.4GHz) travel farther and are less absorbed by physical barriers.

From the CompTIA A+ 220-1101 Official Study Guide, Objective 2.5 – Compare and contrast wireless networking protocols:

“The 2.4GHz frequency band offers greater range and better penetration through walls and obstacles than higher frequencies like 5GHz and 6GHz. Higher frequencies provide faster speeds but are more easily absorbed by walls.”

NFC (Near Field Communication) is not a Wi-Fi technology and works only over very short distances (a few centimeters).
