According to Apple the Lightning cable can extend up to 2 meters (6.5 feet) and work optimally. You can likely find 3rd party (non-Apple) cables that are longer, however Apple onnly recommends and sells cables up to 2 meters.

DNS uses port 53 for both TCP and UDP to serve its purpose of translating human-friendly domain names like 'example.com' into IP addresses that computers use to identify each other on the network. While DNS queries are generally sent using UDP to save on resources due to their small size and need for quick responses, TCP is used for larger queries like zone transfers or when reliability is of more concern over the slight delay that establishing a TCP connection brings. The other ports mentioned serve different protocols entirely (FTP and HTTP) and are not primarily associated with DNS activity.

The correct step is to consult the organization's troubleshooting and maintenance guidelines. This ensures compliance with documented standards, which may include specific handling, reporting, and rectification methods for such issues. Proceeding without this knowledge could violate policy and lead to escalated problems.

The initial step that the technician should take is 'Shut down the workstation and disconnect it from the power source promptly' because unaddressed electrical issues or overheated components may lead to fire risks or additional hardware damage. Immediate shutdown prevents further distribution of electricity to components that could potentially be malfunctioning. While inspecting memory module alignment and checking for physical damage are valid troubleshooting actions, they do not address the immediate hazard presented by the smell and would place the technician at unnecessary risk if the system remained powered.

In virtual computing the Hypervisor is the component that manages and runs the virtual machines. It can be a software running on top of a host operating system or can be a hardware/firmware component that runs without the need for a host operating system.

Cat 5e cabling can handle Gigabit Ethernet connections and the power requirements for PoE up to the 802.3af standard which provides up to 15.4W of power. The cable's length, quality, and rating are factors that can affect its capacity to handle such requirements. It's important to verify there are no existing c-compromises such as cable stretch, exposed wires, or tight bends that could impair its functionality when PoE is applied. Cat 5 is not reliable for Gigabit speeds and is superseded by Cat 5e in potential power handling. Cat 6 and Cat 6a cables can also support this functionality, but the use of shielded twisted pair is not specified in the scenario and could add to complexity and cost.

A community cloud is a cloud service model where infrastructure and resources are shared between multiple organizations from a specific community with common concerns, but it is provided by an external third party. Unlike a public cloud, it is not open for use by the general public, and it varies from a private cloud that is dedicated to a single organization. A hybrid cloud is a combination of private and public cloud features but not a collective service shared by a specific community.

The first step in troubleshooting a problem is to first identify the problem. You will probably be initially given symptoms and then you need to gather information to decipher what the actual problem is.

The initial step to troubleshoot a keyboard typing incorrect characters is to check the keyboard settings in the operating system. It is possible that the keyboard layout has been changed to a different language or layout, which might cause characters to be interpreted incorrectly. While updating drivers or checking the Num Lock key can resolve some issues, they are unlikely to cause incorrect characters to be typed. Moreover, disassembling the laptop to check the connection might be necessary only if initial software checks do not resolve the problem.

A Platform as a Service (PaaS) is a cloud platform that provides end users with a development environment and tooling without them having to setup the networking, servers and install all the software components themselves. Out of the box a PaaS can include a lot of components including the OS, Middleware, Databases and Database Managements systems and much more.

Transmission Control Protocol (TCP) is known for its handshaking process, commonly referred to as the 'three-way handshake'. This process establishes a reliable session between two devices. This protocol ensures that data is transmitted in sequence and without errors, by establishing this connection prior to any data transmission. On the other hand, protocols like SNMP and DHCP are application-layer protocols that do not themselves establish a connection and may use UDP for transmission, which does not provide the same reliability guarantees as a connection-oriented protocol. SSH, while it does use TCP to establish a secure connection, is not primarily defined by the handshaking process. It's notable here because, in this question, TCP is the so-called 'lowest' protocol that involves connection establishment.

Physical damage to an Ethernet cable, such as severe crimping, can impede the cable's ability to maintain a stable connection due to interference and signal degradation. Issues such as a defective NIC or outdated drivers may cause network connectivity problems, but based on the noted physical cable condition, damage to the Ethernet cable is the immediate concern and most probable cause.

The power supply unit (PSU) is the most likely culprit for intermittent shutdowns when there have been no reported changes or symptoms related to software or overheating. The PSU could be failing to provide consistent power due to faults within the unit itself or due to inconsistencies in the incoming power from the power source — such as sags, surges or brownouts. Temperature-related issues, like CPU or overall system overheating, can cause similar problems but are typically accompanied by other symptoms such as performance throttling or error messages related to heat. Other components such as the motherboard or RAM usually exhibit different signs of failure, like POST beeps or memory errors, not typically causing the system to shutdown intermittently without other warnings.

This is false. As long as the Hypervisor can provide the resources (CPU, Memory, etc.) needed to run the OS installed onto the virtual machine there are no limitations. Windows 10, Windows Server, Linux, etc. can all be run virtually regardless of the host OS.

Tone generator/probe will help you identify which cable runs to your office so you can see if it is connected. A loopback plug is for testing the NIC, which we already confirmed good. PING is an application/command used to test network connectivity, it won't help here. A cable tester would likely be the next tool used once we find our cable and confirm that it is connected.
