CompTIA Updated CS0-002 Exam Questions and Answers by edison

The correct answer is A. Enable secure boot in the hardware and reload the operating system. Secure boot is a feature of UEFI that ensures that only trusted and authorized code can execute during the boot process. Secure boot can prevent boot malware, such as rootkits or bootkits, from compromising the system before the operating system loads1. To enable secure boot, the hardware must support UEFI and have a firmware that implements the secure boot protocol. The operating system must also support UEFI and have a digital signature that matches the keys stored in the firmware. If the operating system was installed in legacy mode or does not have a valid signature, it may not boot with secure boot enabled. Therefore, it may be necessary to reload the operating system after enabling secure boot in the hardware2.

B. Reconfigure the system’s MBR and enable NTFS is not correct. MBR stands for Master Boot Record, and it is a legacy partitioning scheme that stores information about the partitions and the boot loader on a disk. NTFS stands for New Technology File System, and it is a file system that supports features such as encryption, compression, and access control. Reconfiguring the system’s MBR and enabling NTFS would not enable secure boot UEFI features, as they are not related to UEFI or secure boot. Moreover, MBR is incompatible with UEFI, as UEFI requires a different partitioning scheme called GPT (GUID Partition Table)3.

C. Set UEFI to legacy mode and enable security features is not correct. Legacy mode is a compatibility mode that allows UEFI systems to boot using legacy BIOS methods. Legacy mode disables some of the features and benefits of UEFI, such as secure boot, faster boot time, or larger disk support. Setting UEFI to legacy mode would not enable secure boot UEFI features, but rather disable them.

D. Convert the legacy partition table to UEFI and repair the operating system is not correct. Converting the legacy partition table to UEFI means changing the partitioning scheme from MBR to GPT, which is required for UEFI systems to boot. However, this alone would not enable secure boot UEFI features, as it also depends on the firmware settings and the operating system support. Repairing the operating system may or may not fix any issues caused by converting the partition table, but it would not necessarily enable secure boot either.

To prevent adversaries from intercepting response and recovery details. Using a secure method of communication during incident response is important to prevent adversaries from intercepting response and recovery details that could reveal the incident response team’s actions, strategies, or findings. If the adversaries can intercept the communication, they could use it to evade detection, escalate their privileges, or launch further attacks. To ensure intellectual property remains on company servers, to have a backup plan in case email access is disabled, or to ensure the management team has access to all the details that are being exchanged are other possible reasons to use a secure method of communication, but they are not as important as preventing adversaries from intercepting response and recovery details.

A secure supply chain program is a set of processes and practices that aim to protect the supply chain from various risks, such as cyberattacks, data breaches, fraud, theft, sabotage, or natural disasters1. A secure supply chain program can help to ensure the integrity, availability, and confidentiality of the products, services, data, and systems involved in the supply chain. A secure supply chain program with governance means that there are clear roles, responsibilities, policies, procedures, and controls for managing the security of the supply chain. This can help to monitor and enforce the compliance of the third-party service provider with the requirement to source talent from its own country. A secure supply chain program with governance can also help to identify and mitigate any potential threats or vulnerabilities in the supply chain. Implementing blacklisting for IP addresses from outside the country (B) may not be sufficient or effective, as IP addresses can be spoofed or bypassed by attackers. Implementing strong authentication controls for all contractors © may not be relevant or adequate, as authentication controls do not prevent the sourcing of talent from other countries. Implementing user behavior analytics for key staff members (D) may not be applicable or useful, as user behavior analytics do not verify the origin or location of the talent.

Use data-at-rest scans to locate and identify sensitive data. This option is the best DLP consideration for addressing the sensitive data on the file servers. Data-at-rest scans are performed on data that is stored on a device or a network, such as file servers, and can help identify and classify sensitive data based on predefined policies or rules. The other options are not relevant for this scenario, as they either deal with data in transit (network DLP appliances), data in use (endpoint DLP agents), or cloud-based data (CASB device).
