Q11Which technology provides a flexible and secure wireless communications system that can supplement or fully replace a wired Ethernet LAN?
✓ Correct answer: C. WLAN
A Wireless Local Area Network (WLAN) can augment or replace a wired Ethernet LAN, offering flexible connectivity within a local area.
Q12An employee on extended business travel uses a personal mobile device to handle sensitive company data. Which of the following is the most critical measure to put in place?
✓ Correct answer: C. Real-time remote monitoring of the device's activity and usage
Real-time remote monitoring of the personal device during extended travel allows continuous oversight, enabling prompt detection and response to any unauthorized access or suspicious activity involving sensitive company data.
Q13Which of the following are examples of secure VPN tunneling protocols? (Choose 2)
✓ Correct answer: B. IPsec
IPsec (Internet Protocol Security) authenticates and encrypts IP packets to establish secure VPN tunnels. TLS (Transport Layer Security) encrypts communications over networks and is also used in VPN implementations. bcrypt is a password hashing algorithm, not a tunneling protocol. WEP is a deprecated and insecure wireless encryption standard, not a VPN protocol.
Q14What security component is composed of hardware, software, and firmware that together enforce a system's security policy?
✓ Correct answer: D. Security Kernel
The Security Kernel comprises hardware, software, and firmware components that collectively implement and enforce the security policy of a computer system.
Q15Nathan wants to restrict company-issued mobile devices so they can only be used within the organization's physical premises. What type of authentication should he deploy?
✓ Correct answer: D. Context-aware authentication
Context-aware authentication uses contextual signals such as geolocation to enforce location-based access policies, ensuring devices can only be authenticated within the facility's boundaries. PINs and biometrics verify identity but cannot enforce location restrictions. 'Content-aware authentication' is a fabricated term.
Q16What is the name of the hardware-based security chip that stores cryptographic keys and protects sensitive information on a device?
✓ Correct answer: D. TPM
A TPM (Trusted Platform Module) is a dedicated hardware security chip that stores cryptographic keys and other sensitive data, providing a hardware root of trust for the device. A DMZ is a network security zone. SLP is the Service Location Protocol. TFTP is the Trivial File Transfer Protocol — none of these are encryption key storage devices.
Q17Gabrielle wants to use a single cable that carries both digital audio and digital video signals. Which connector type should Malcolm recommend?
✓ Correct answer: C. HDMI
HDMI transmits both digital audio and digital video over a single cable. S-video is an older analog video-only connector. RGB requires separate cables per color channel. RCA connectors are analog and typically carry audio or composite video separately.
Q18Which device uses satellites to determine your geographic location and can be used for turn-by-turn navigation?
✓ Correct answer: C. GPS device
GPS (Global Positioning System) devices communicate with satellites to pinpoint your location. Because they require a clear line of sight to satellites, signal quality can be reduced in bad weather or dense environments.
Q19Which command opens the System Information tool in Windows?
✓ Correct answer: D. msinfo32
Typing msinfo32 in the Windows search box or Run dialog opens the System Information tool, which provides details about hardware, system components, and software.
Q20Which of the following file systems provides the best security features?
✓ Correct answer: A. NTFS
NTFS (New Technology File System) offers superior security compared to FAT32 through support for file and folder permissions and encryption. Privacy filter and Local Security Policy are not file systems.
