A. A network's domain name system server has not been fully operational for one month. B. An employee accidentally modified a customer account incorrectly. C. A company has an unacceptably high network downtime during high-traffic time periods. D. A company stores sensitive customer data without access controls. Answer: B Explanation: A violation ofintegrityoccurs whendata is modified incorrectly, whether intentionally or by accident. In this case, anemployee modifying a customer account incorrectlydemonstrates a breach of data integrity. A and Crelate toavailability, as they describe system downtime. Drelates toconfidentiality, as it describes improper data protection. 2.A company is developing a data protection methodology in order to improve data protection measures. What is a strategy that should be used? A. Use a variable network topology B. Increase wireless access point range C. Enhance physical resource security D. Implement wired equivalent privacy (WEP) Answer: C Explanation: Enhancing physical resource securityensures that servers, networking devices, and data storage facilities are protected from unauthorized physical access, theft, or tampering. This includes measures like biometric authentication, surveillance, and restricted access zones. Using a variable network topologydoes not directly protect data. Increasing wireless access point rangemay improve connectivity but does not enhance security. WEPis weak and should not be used for data protection. 3.A host is already set up with an operating system. An administrator wants to install a hypervisor atop the operating system to allow for setting up virtual machines. Which hypervisor should be used? A. Open source B. Proprietary C. Type 1 D. Type 2 Answer: D Explanation: AType 2 hypervisor(hosted hypervisor) runs on top of an existing operating system and allows for the creation of virtual machines. Examples include VMware Workstation and Oracle VirtualBox. Type 1 hypervisorsrun directly on hardware without an OS (e.g., VMware ESXi, Microsoft Hyper-V). Open-source and proprietarydescribe licensing models, not hypervisor types. 4.A company wants to use a cloud service to obtain virtual machines with pre-installed and configured software. Which cloud service model should be used? Download Valid Network and Security Foundation Exam Dumps for Best Preparation 3 / 5 A. Software as a Service (SaaS) B. Infrastructure as a Service (IaaS) C. Platform as a Service (PaaS) D. Function as a Service (FaaS) Answer: C Explanation: Platform as a Service (PaaS)provides a pre-configured computing environment that includes an operating system, runtime, and development tools, making it ideal for developers who want a ready-to-use platform. Examples include Google App Engine and Microsoft Azure App Services. SaaSprovides fully hosted applications, not just pre-configured virtual machines. IaaSprovides infrastructure without pre-installed software. FaaSexecutes specific functions without persistent infrastructure. 5.Which component of the IT securityCIA triadis a driver for enabling data encryption? A. Application B. Integrity C. Confidentiality D. Availability Answer: C Explanation: Confidentialityensures that sensitive information is protected from unauthorized access.Encryptionis a key mechanism used to maintain confidentiality by converting readable data into a secure format that can only be accessed with a decryption key. Integrityensures data is not altered improperly but does not directly relate to encryption. Availabilityfocuses on system uptime and accessibility. Applicationis not a component of the CIA triad. 6.A company wants to implement a cloud service to obtain access to virtual machines. The company wants to be able to choose the operating systems and configure each of the machines. What is the type of cloud service model that fits the needs of this company? A. Function as a Service (FaaS) B. Infrastructure as a Service (IaaS) C. Platform as a Service (PaaS) D. Software as a Service (SaaS) Answer: B Explanation: Infrastructure as a Service (IaaS)provides virtualized computing resources over the cloud, including virtual machines where users can install and configure their own operating systems and applications. It offers flexibility and scalability without requiring hardware investment. Examples include AWS EC2 and Microsoft Azure Virtual Machines. FaaSexecutes small code functions without infrastructure management. PaaSprovides a managed platform but not full OS control. SaaSoffers ready-to-use applications without infrastructure control. Download Valid Network and Security Foundation Exam Dumps for Best Preparation 4 / 5 7.What is an IT infrastructure security tenet of the CIA triad that counters passive attacks that aim to steal or intercept data? A. Adaptation B. Confidentiality C. Availability D. Integrity Answer: B Explanation: Confidentialityprotects data from unauthorized access, includingpassive attackslike eavesdropping, wiretapping, and packet sniffing. Encryption, access controls, and secure authentication mechanisms help enforce confidentiality. Availabilityensures uptime and system accessibility. Integrityensures data accuracy but does not prevent interception. Adaptationis not part of the CIA triad. 8.Access to a company's information system requires a user to be within a valid geographic location and to enter a valid username and password. Which concept does this scenario demonstrate? A. Certificate verification B. Multifactor authentication C. User-based accounting D. Single sign-on Answer: B Explanation: Multifactor authentication (MFA)requires users to verify their identity usingmultiple factors, such as something they know (password), something they have (a token or phone), or somewhere they are (geolocation-based access control). Requiring both location verification andpassword authentication demonstrates MFA. Certificate verificationchecks digital certificates for security but does not use multiple authentication factors. User-based accountinglogs user activities but does not verify identity. Single sign-on (SSO)allows access to multiple systems with one login but is not necessarily MFA. 9.When setting up a network, a technician needs a router that connects computers together and connects computers to the internet. Which router should be used? A. Inter-provider border router B. Subscriber edge router C. Broadband router D. Core router Answer: C Explanation: A broadband router is a type of network router that connects multiple computers within a local network while also providing internet access. It functions as a gateway between the local network and the internet Download Valid Network and Security Foundation Exam Dumps for Best Preparation 5 / 5 by handling data packet transmission and routing. Broadband routers are widely used in small offices and homes because they offer essential networking services, including DHCP, NAT, and sometimes wireless connectivity. Inter-provider border routersare used by ISPs to route data between different providers and do not serve as an internet gateway for end users. Subscriber edge routersare typically deployed at the edge of an ISP's network to connect subscriber networks but do not provide full internet routing functionalities. Core routersoperate at the backbone level of a network, facilitating high-speed data transfer but not connecting end-user devices directly. 10.An attacker sends emails claiming that an online account has been locked. The email provides a fake link with the goal of tricking users into providing login credentials. Which malicious attack strategy is represented in the scenario? A. Phishing B. IP address spoofing C. Session hijacking D. Man-in-the-middle attack Answer: A Explanation: Phishingis a cyberattack where attackers impersonate legitimate entities (e.g., banks, companies) and send fraudulent emails or messages designed to trick recipients into revealing sensitive information, such as usernames, passwords, or financial details. The fake link in the email directs victims to a malicious site that captures their credentials. IP address spoofingdisguises a system ’ s identity but does not involve email deception. Session hijackingtakes over an active session but does not involve email scams. Man-in-the-middle attackintercepts communication rather than tricking users via emails. 11.Users of a network have been experiencing issues. In the course of troubleshooting, an administrator wants to test DNS resolution against a host. Which command in Linux should be used for this purpose? A. traceroute B. netstat C. dig D. ifconfig Answer: C Explanation: Thedigcommand in Linux is used for DNS troubleshooting. It queries DNS records and provides detailed information about domain name resolutions. traceroutetracks the path packets take to a destination but does not diagnose DNS. netstatlists active connections, not DNS records. ifconfigis used for managing network interfaces.
