The best option to help the administrator secure the corporate resources is B. Biometric scanner.

A biometric scanner is a device that can authenticate a user’s identity based on their physical or behavioral characteristics, such as fingerprint, iris, face, voice, or signature. A biometric scanner can provide a high level of security and convenience for accessing corporate laptops, as it can prevent unauthorized users from accessing the devices and eliminate the need to remember passwords .

The other options are not the best options for this scenario. A Trusted Platform Module (TPM) is a chip that can store encryption keys and other sensitive data on a laptop. A TPM can enhance the security of data and devices, but it does not limit access to authorized users by itself. A TPM can work with a password or a biometric scanner to provide multifactor authentication . A laptop lock is a device that can physically secure a laptop to a desk or other object using a cable and a lock. A laptop lock can deter theft or tampering, but it does not prevent unauthorized users from accessing the laptop if they have the password or the key. Encryption is a process that can protect data on a laptop by transforming it into an unreadable format using a key. Encryption can prevent unauthorized users from accessing or modifying the data, but it does not prevent them from accessing the laptop itself.

Ac stands for 802.11ac, which is a wireless networking standard that operates in the 5 GHz frequency band and offers a maximum data rate of 1.3 Gbps. 802.11ac is also backward compatible with 802.11a, 802.11b, 802.11g, and 802.11n standards. If a technician wants to install a WAP (wireless access point) in the company break room that has a rating of higher than 50 Mbps and minimal range to avoid interference with other access points, they should select the 802.11ac standard.

A hybrid cloud model would best address the company’s needs of saving money by leveraging the cloud while still being able to customize the infrastructure. A hybrid cloud model is a combination of public and private cloud services, connected by a secure network. A public cloud service is a cloud service that is offered by a third-party provider over the Internet, and is shared by multiple customers. A private cloud service is a cloud service that is dedicated to a single customer, and is hosted either on-premises or by a third-party provider. A hybrid cloud model allows the company to use the public cloud for cost-effective and scalable services, such as storage, backup, or analytics, and use the private cloud for more sensitive or customized services, such as security, compliance, or performance. A hybrid cloud model also enables the company to move workloads between the public and private cloud as needed, depending on the demand, availability, or cost. A hybrid cloud model can provide the company with the best of both worlds: the flexibility and efficiency of the cloud, and the control and customization of the infrastructure.

The correct answer is C. Cat 6.

An RJ45 connector is a standard type of physical connector for network cables. RJ45 connectors are used almost exclusively with Ethernet cables and networking1. Ethernet cables are twisted pair cables that carry data signals between devices on a network, such as computers, routers, switches, and servers2.

There are different categories of Ethernet cables, such as Cat 5, Cat 5e, Cat 6, and Cat 7, that have different specifications and performance levels. Cat 6 is one of the most common types of Ethernet cables, which supports data transfer speeds up to 10 Gbps and bandwidth up to 250 MHz3. Cat 6 cables have four pairs of copper wires, each with a plastic insulation and a foil or braided shield. The wires are twisted together to reduce crosstalk and interference4.

To terminate a Cat 6 cable, an administrator needs to use an RJ45 connector that matches the wiring scheme of the cable. There are two common wiring schemes for Ethernet cables: T568A and T568B. The administrator needs to strip the cable jacket, untwist the wires, arrange them in the correct order according to the chosen scheme, trim the excess wire, and insert them into the RJ45 connector. Then, the administrator needs to use a crimping tool to secure the wires and the connector4.

Optical cables are not terminated with RJ45 connectors, but with different types of connectors that can transmit light signals, such as SC, ST, LC, or MTRJ connectors. Optical cables are used for fiber-optic networks that can carry data over long distances at high speeds.

Serial cables are not terminated with RJ45 connectors, but with different types of connectors that can transmit serial data signals, such as DB9, DB25, or DE9 connectors. Serial cables are used for connecting devices that use serial communication protocols, such as modems, printers, scanners, or keyboards.

USB cables are not terminated with RJ45 connectors, but with different types of connectors that can transmit universal serial bus data signals, such as USB-A, USB-B, USB-C, or Micro-USB connectors. USB cables are used for connecting devices that use USB communication protocols, such as flash drives, cameras, mice, or chargers.
