Load balancing is a method used to distribute incoming network traffic across multiple servers. In this scenario, the administrator is tasked with ensuring that all four servers can serve the same website, which is a typical use case for load balancing.

Load balancing (Answer A): Distributes web traffic across multiple servers to ensure availability and reliability.

Direct access (Option B): Refers to client devices connecting directly to a network resource, unrelated to the described scenario.

Overprovisioning (Option C): Refers to allocating more resources than are currently needed, not relevant to load distribution.

Network teaming (Option D): Involves combining multiple network interfaces for redundancy or increased throughput but doesn't address server distribution.

CompTIA Server+ Reference:This topic is covered under SK0-005 Objective 1.4: Explain networking concepts for server environments.

A public cloud model will most likely meet the need of eliminating all company-owned data centers. A public cloud is a type of cloud computing service that is provided by a third-party vendor over the internet. A public cloud offers scalability, flexibility, and cost-effectiveness for hosting servers and applications, as the customers only pay for the resources they use and do not have to maintain their own infrastructure. A public cloud can also provide high availability, security, and performance for the servers and applications, as the vendor manages the underlying hardware and software. A public cloud can support various types of services, such as software as a service (SaaS), platform as a service (PaaS), or infrastructure as a service (IaaS). References: [CompTIA Server+ Certification Exam Objectives], Domain 1.0: Server Administration, Objective 1.2: Given a scenario, compare and contrast server roles and requirements for each.

HTTPS (Secure Web Traffic): Port 443 is the standard port for HTTPS, which is essential for encrypting communication between web browsers and a secure website. (CompTIA Server+ Objectives SK0-004: 4.1)

Why other options are not essential:

25 (SMTP): Used for email transmission

53 (DNS): Used for domain name resolution

**3389 (RDP): ** Used for remote desktop connections

**8080 (Alternate HTTP): ** Sometimes used for web servers, but not the standard secure port

A headless installation is an installation method that does not require a graphical user interface (GUI) or a monitor, keyboard, and mouse. It can be done remotely through a network connection or a command-line interface. A headless installation is suitable for a server that has limited resources and does not need a GUI.
