The authentication method that this setup describes is SSO (Single Sign-On). SSO is a technique that allows a user to log in once to a main web application and then access multiple other applications or services without having to re-enter credentials. SSO simplifies the user experience and reduces the number of passwords to remember and manage.

The valid alternative to maintain a deployed proxy technology while saving physical space in the data center by moving the network service to the virtualization infrastructure is NFV (Network Function Virtualization). NFV is a technique that allows network functions, such as proxies, firewalls, routers, or load balancers, to be implemented as software applications running on virtual machines or containers. NFV reduces the need for dedicated hardware devices and improves scalability and flexibility of network services. Reference: CompTIA Network+ N10-008 Certification Study Guide, page 440; The Official CompTIA Network+ Student Guide (Exam N10-008), page 16-11.

NFV can be used to virtualize a wide variety of network functions, including proxy servers. By virtualizing proxy servers, organizations can save physical space in the data center and improve the scalability and efficiency of their networks.

To virtualize a proxy server using NFV, an organization would need to deploy a virtualization platform, such as VMware ESXi or Microsoft Hyper-V. The organization would then need to install a virtual proxy server appliance on the virtualization platform.

Once the virtual proxy server appliance is installed, it can be configured and used just like a physical proxy server.

NFV is a relatively new technology, but it is quickly gaining popularity as organizations look for ways to improve the efficiency and scalability of their networks.

A SQL server connects over port 1433. Port numbers are used to identify specific applications or services on a network device. Port 1433 is the default port for Microsoft SQL Server, which is a relational database management system that uses SQL (Structured Query Language) to store and manipulate data. Reference: CompTIA Network+ N10-008 Certification Study Guide, page 147; The Official CompTIA Network+ Student Guide (Exam N10-008), page 6-4.

The device that is required when connecting an endpoint device with an RJ45 port to a network device with an ST port is a media converter. A media converter is a device that converts signals between different types of media, such as copper and fiber. An RJ45 port is used for twisted-pair copper cables, while an ST port is used for fiber-optic cables. A media converter allows these two types of cables to interconnect and communicate.

The user's workstation does not support 802.11 ax, which is the technical name for Wi-Fi 6. Wi-Fi 6 is a new wireless standard that offers faster speeds, higher capacity, and lower latency than previous standards. However, to take advantage of these benefits, both the router and the workstation need to support Wi-Fi 6. If the workstation only supports an older standard, such as 802.11 ac or Wi-Fi 5, then the throughput will not increase even if the router supports Wi-Fi 6.

Jitter is the variation in the delay of packets arriving at a destination. Jitter can cause problems for real-time applications, such as voice and video, that require consistent and smooth delivery of packets. A geographically remote office that connects to the main office via a WAN link may experience high jitter due to factors such as network congestion, routing changes, or link quality.

Jitter can be reduced by using quality of service (QoS) mechanisms that prioritize and shape traffic according to its importance and sensitivity. Reference: [CompTIA Network+ Certification Exam Objectives], What is Jitter? | Network Jitter Explained | SolarWinds

RG6 is a type of coaxial cable that is commonly used for cable TV and internet services. A cable modem is a device that modulates and demodulates signals over a coaxial cable network to provide broadband internet access. A SOHO situation refers to a small office/home office environment that typically has a single cable modem connected to a single coaxial cable outlet. Therefore, RG6 is the most appropriate demarcation connection for a cable modem in a SOHO situation. Reference:

A bad switch port is the most likely cause of CRC errors on a SAN switch. CRC stands for cyclic redundancy check, which is a method of detecting errors in data transmission. A SAN switch is a device that connects storage devices and servers in a storage area network (SAN), which is a high-performance network that provides block-level access to data. A bad switch port can cause CRC errors due to physical damage, faulty wiring, or misconfiguration. CRC errors can result in data corruption or loss, which can affect the performance and availability of the SAN. Reference:

Documenting the lessons learned is the best method for passing along the exact steps other technicians should follow in case the issue arises again. Lessons learned are the knowledge and experience gained from completing a project or solving a problem. Documenting the lessons learned helps to capture the best practices, challenges, solutions, and recommendations for future reference and improvement. Documenting the lessons learned can also help to update the knowledge base, standard operating procedures, or policies related to the issue.
