220-1101 Exam Dumps - CompTIA A+ Certification Exam: Core 1

When a computer frequently freezes and requires hard restarts, the first step a technician should take, especially when hardware components have not been recently changed, is to read the event logs. Event logs can provide critical insights into what is causing the system to freeze, including errors and warnings that precede the freeze. This information is essential for diagnosing software or operating system issues that might be causing instability. Checking the temperature or updating drivers might be subsequent steps based on findings from the event logs.

References:CompTIA A+ Core 1 (220-1101) troubleshooting section, which emphasizes the importance of using system logs to diagnose issues.

Containers are lightweight, isolated environments perfect for deploying and running microservices in a cloud or virtualized infrastructure.

In the SaaS (Software as a Service) model, the service provider manages the infrastructure, platforms, and software applications, including maintenance tasks such as application patching. Users access the applications over the internet, and the provider is responsible for ensuring the software is up to date, secure, and performing optimally. This model contrasts with IaaS (Infrastructure as a Service) and PaaS (Platform as a Service), where the customer has more control and responsibility over the environment and may need to manage patching for applications they develop or install.

References: SaaS is designed to relieve users from the complexity of software maintenance, including patch management, as highlighted in cloud computing service model descriptions.

A DHCP lease is a temporary assignment of an IP address and other network configuration parameters (such as DNS and gateway) to a device. The lease is renewed periodically to maintain the assignment.

Why Not A (A definition of the scope of addresses): The DHCP scope defines the range of IP addresses but is not the lease itself.

Why Not B (A reservation of an IP configuration): DHCP reservations ensure a specific device always receives the same IP address, but this is not the lease.

Why Not D (A translation of network names to IP addresses): This describes DNS, not DHCP.

Mobile Device Management (MDM) enables administrators to enforce controls on enterprise devices, such as restricting apps, ensuring compliance, and remotely managing security policies.

Why Not B (MFA): Multi-Factor Authentication secures user access but does not control device configurations.

Why Not C (VPN): VPN secures communication but does not enforce device controls.

Why Not D (SSL): SSL secures data in transit but does not provide device management.
