Operational procedure n5

Which of the following could be used to meet regulatory compliance requirements associated with the monitoring of employee actions on their work computer by providing a customizable dialog box with a textual warning to the user before they log in to their Windows 10 workstation?

• Request form

• Splash screen

• Chain of custody

• Change request form

Answer explanation

A splash screen or interactive login screen is a graphical control element consisting of a window containing an image, a logo, or textual content. In Windows 10, system administrators can configure the textual content of the interactive logon dialog box to display a warning or the terms of an acceptable use policy to meet regulatory requirements. This interactive log on dialog is commonly used by organizations to notify their employees that they are subject to monitoring while using their work computers.

Which of the following is required for evidence to be admissible in a court of law?

• Order of volatility

• Legal hold

• Right to audit

• Chain of custody

Answer explanation

Chain of custody forms list every person who has worked with or who has touched the evidence that is a part of an investigation. These forms record every action taken by each individual in possession of the evidence. Depending on the organization's procedures, manipulation of evidence may require an additional person to act as a witness to verify whatever action is being taken. A legal hold is a process that an organization uses to preserve all forms of potentially relevant information when litigation is pending or reasonably anticipated. A right to audit is a clause in a contract or service agreement that allows a company the authority to audit the systems and information processed. Order of volatility refers to the order in which you should collect evidence.

offices are frequently experiencing under-voltage events, sags, and power failures. Which of the following solutions would protect their servers from these issues?

• Surge suppressor

• Uninterruptible power supply

• Line conditioner

• Diesel generator

Answer explanation

A uninterruptible power supply (UPS) is a battery backup. It is used to protect one server or workstation from under-voltage events, sags, and power failures. If there is a loss of power, system operation can be sustained for a few minutes or hours using a battery backup, depending on the load. A diesel generator is a mechanical device that converts rotational motion created by a diesel motor into electrical energy. Generators take 30-60 seconds to turn on and have the electrical load transferred to them. Generators are useful for long-duration power loss events, not under-voltage events. A line conditioner is a device that adjusts voltages in under-voltage and overvoltage conditions to maintain a 120 V output. Line conditioners raise a sag or under-voltage event back to normal levels, but they cannot protect the line from a complete power failure or power outage. A surge protector defends against possible voltage spikes that could damage your electronics, appliances, or equipment. A power strip will not protect against voltage spikes

Your router has been turning itself off and on again for a few weeks. You begin to think back to when these issues began to occur and remember that each time it happened the lights also dimmed momentarily. You hook up a device to monitor the power being supplied to the router and identify that brownouts are frequently occurring, resulting in the router's power cycling. What should you (a network technician) do to solve this problem?

• Install a UPS

• Install an upgraded router

• Install a new electrical outlet

• Install a surge protector

Answer explanation

The best solution would be to install a UPS. Since you are a network technician and not an electrician, you should not install a new electrical circuit. The primary function of UPS is to provide battery backup when the electrical power fails or drops to an unacceptable voltage level. It ensures that your electrical equipment gets a consistent current so damage and device power cycling do not occur. A surge protector defends against possible voltage spikes that could damage your electronics, appliances, or equipment. A network technician is not qualified to install a new electrical outlet since that is a job for an electrician. The scenario presents issues that focus on the power levels, therefore installing an upgraded router would not solve these issues.

Which of the following is the purpose of an ESD mat?

• Protects equipment from dust or dirt

• Protects casings from scratches and dents

• Protects the technician from accidental shocks

• Protects equipment against accidental static discharge

Answer explanation

An electrostatic discharge (ESD) mat is made from materials that dissipate static to protect sensitive electronic equipment and components. An electrostatic discharge (ESD) is the release of a charge from metal or plastic surfaces that occurs when a potential difference is formed between the charged object and an oppositely charged conductive object. This electrical discharge can damage silicon chips and computer components if they are exposed to it.

A user has asked you for a recommendation for a word processing program for their home computer. The user doesn't want to pay for a license to be able to use the word processor. Based on this, what type of license would you recommend to the user?

• Personal license

• Corporate license

• Enterprise license

• Open license

Answer explanation

n open license or free license is the legal statement that allows free content and free software to be free. Since the customer doesn't want to pay for a license, the user must get a word processing program that uses an open license to not pay for their software. For example, OpenOffice is an open license-based software that provides a word processor that can be used on Windows, Linux, or OS X for free. A Personal license is an option for private individuals who purchase a license with their own funds and solely for their own use. Personal licenses are not to be purchased, refunded, or in any way financed by companies. A business license is the standard licensing option for organizations and business entities. With Microsoft, a company can purchase anywhere from 1 to 300 user licenses under the business license program. An enterprise license is like a business license, but for an unlimited number of users and is designed for large corporate and government networks.

A coworker is creating a file containing a script. You look over their shoulder and see "net use s:\\fileserver\videos" in the file. Based on this, what type of file extension should this script use?

• .bat

• .js

• .py

• .vbs

Answer explanation

Batch scripts run on the Windows operating system and, in their simplest form, contain a list of several commands that are executed in a sequence. A .bat file is used for a batch script. You can run the file by calling its name from the command line or double-clicking the file in File Explorer. Generally, batch file scripts run from end to end and are limited in branching and user input. Python is a general-purpose programming language that can develop many different kinds of applications. It is designed to be easy to read, and the programs use fewer lines of code compared to other programming languages. The code runs in an interpreter. Python is preinstalled on many Linux distributions and can be installed on Windows. Python scripts are saved using the .py extension. JavaScript is a scripting language that is designed to create interactive web-based content and web apps. The scripts are executed automatically by placing the script in the HTML code for a web page so that when the HTML code for the page loads, the script is run. JavaScript is stored in a .js file or as part of an HTML file. VBScript is a scripting language based on Microsoft’s Visual Basic programming language. Network administrators often use VBScript to perform repetitive administrative tasks. With VBScript, you can run your scripts from either the command-line or the Windows graphical interface. Scripts that you write must be run within a host environment. Windows 10 provides Internet Explorer, IIS, and Windows Script Host (WSH) for this purpose.

Tim has requested to install a security update to the Dion Training web server during the next maintenance window. At the change control board meeting, Tim presents the requested change and gains approval from the change board. Before Tim installs the update, which of the following should be documented as a result of the change board's approval?

• Purpose of the change

• Risk level of the change

• Affected systems/impact of the change

• Date and time of the change

Answer explanation

The approved date and time of the change needs to be documented as a result of the change board's approval. The change board will approve all changes per the change management procedures in the organization. To get a change approved, a technician must submit a request form that lists the purpose of the change, the scope of the change, affected systems and impact of the change, the risk analysis and resulting risk level of the change, and the proposed date/time of the change. Once the change board approves the change at the change control board meeting, the technician or the change board needs to document the approved date and time for the change to be implemented.

Dion Training is creating troubleshooting guides and frequently asked questions for its new customer service technicians. Which of the following would MOST likely contain these documents?

• Network topology diagrams

• Asset management database

• Knowledge base articles

• Password policy

Answer explanation

A Knowledge Base (KB) is a reference document that is used to assist a technician when they are installing, configuring, and troubleshooting hardware and software. A knowledge base article might be created by a vendor to support their products, too. A company might create an internal KB, populated with guidelines, procedures, information, and frequently asked questions from their service tickets. A network topology is the shape or structure of a network in a physical or logical format as depicted in a network diagram. Physical network topologies include the actual appearance of the network layout. Logical network topologies include the flow of data across the network. A password policy is a set of rules designed to enhance computer security by encouraging users to employ strong passwords and use them properly. A password policy is often part of an organization's official regulations and may be taught as part of security awareness training. It contains items like password complexity, password age, and password history requirements. An asset management database identifies each asset and records its location, attributes, and value in a database.

You are working at the service desk when you receive a call from an upset user because their workstation cannot receive any emails. Which of the following should you use to document this phone call?

• Asset management database

• Network topology diagrams

• Incident report

• Knowledge base articles

Answer explanation

An incident report is used to document any issues, problems, or incidents in the network. Incident reports are often consolidated into an incident database known as a trouble ticket system. The system should document the number of the incident, the point of contact for the workstation, the priority of the incident, the problem description, and a history of work performed to resolve the incident for the user. An asset management database tracks the number of assets deployed, on order, and in storage. A Knowledge Base (KB) is a reference document that is used to assist a technician when they are installing, configuring, and troubleshooting hardware and software. A knowledge base article might be created by a vendor to support their products, too. A company might create an internal KB, populated with guidelines, procedures, information, and frequently asked questions from their service tickets. A network topology is the shape or structure of a network in a physical or logical format as depicted in a network diagram. Physical network topologies include the actual appearance of the network layout. Logical network topologies include the flow of data across the network.
