WGU (JY02) Managing Cloud Security Exam Questions

The network is the component that enables customers to transfer data into and out of a cloud environment. It provides the connectivity through which data is uploaded, downloaded, and exchanged between customer systems and cloud infrastructure.

Firewalls protect the network by filtering traffic, load balancers distribute requests across resources, and virtual displays present interfaces, but none directly facilitate the transfer of data.

In cloud models, secure networking is critical. Protocols like TLS encrypt traffic, while VPNs and private links provide additional isolation. Reliable networking ensures availability, while strong controls safeguard confidentiality and integrity. Customers must ensure that the cloud provider offers secure, high-performance network services to support business needs.

The STRIDE threat model identifies six categories: Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, and Elevation of privilege. In this scenario, the accountant modified data they were not authorized to change. This is an act of Tampering, which refers to unauthorized alteration of data or systems.

Spoofing would involve impersonating another identity, denial of service would block availability, and elevation of privilege would involve gaining higher access rights. The accountant already had legitimate access but misused it to alter data outside their scope of responsibility.

Tampering compromises data integrity, one of the pillars of the CIA triad. In cloud and enterprise systems, safeguards against tampering include role-based access control, least privilege, and auditing to detect unauthorized changes. Recognizing this as tampering helps in identifying insider misuse and implementing compensating controls.

Without a clear understanding of infrastructure and software, the leadership team must first conduct an inventory of assets. An asset inventory provides a comprehensive list of hardware, software, and services that support business operations.

Creating checklists, defining criteria, and assigning roles are important, but they rely on knowing what assets exist. Without an inventory, the disaster recovery plan would miss critical dependencies, making recovery incomplete or impossible.

Performing an inventory supports business impact analysis, risk assessments, and recovery prioritization. It ensures that all critical systems are accounted for and appropriate recovery strategies can be designed. Asset inventories are a foundational best practice for disaster recovery and continuity planning.

The correct approach for sanitizing a USB thumb drive while preserving its usability is overwriting. Overwriting involves replacing the existing data on the device with random data or specific patterns to ensure that the original information cannot be recovered. This process leaves the physical device intact, allowing it to be reused securely.

Physical destruction, such as shredding, renders the device unusable. Degaussing only works on magnetic media like hard disks or tapes, not on solid-state or flash-based USB drives. Key revocation applies to cryptographic keys and not to physical devices.

By using overwriting, organizations comply with data sanitization standards while balancing operational efficiency. Many tools exist that perform multi-pass overwrites to meet regulatory requirements such as those from NIST or ISO. This ensures that sensitive data is removed while allowing the device to remain in circulation for continued use.

The method described is striping, which is a technique used in RAID configurations to improve performance and distribute risk. Striping involves splitting data into smaller segments and writing those segments across multiple disks simultaneously. For example, if a file is divided into four parts, each part is written to a separate disk in the RAID array.

This parallelism enhances input/output (I/O) performance because multiple drives can be accessed at once. It also provides resilience depending on the RAID level. While striping by itself (RAID 0) increases performance but not redundancy, when combined with mirroring or parity (e.g., RAID 5 or RAID 10), it offers both speed and fault tolerance.

The purpose of striping in the data management context is to optimize how data is stored, accessed, and protected. It is fundamentally different from archiving, mapping, or crypto-shredding, as those serve different objectives (long-term storage, logical placement, or secure deletion). Striping is central to high-performance storage systems and supports availability in mission-critical environments.
