Eccouncil Certified Cloud Security Engineer (CCSE) 312-40 Exam Practice Test

Answer : A

To enhance the performance of a MySQL database running on Compute Engine quickly and in a cost-effective manner, Stephen can dynamically resize the SSD persistent disk to 500 GB. Here's why this option is effective:

Increased IOPS and Throughput: SSDs provide higher input/output operations per second (IOPS) and throughput compared to traditional hard drives. By increasing the size of the SSD persistent disk, Stephen can benefit from increased IOPS and throughput, which are crucial for database performance, especially when dealing with large volumes of data imports and normalization processes1.

No Downtime Required: Dynamically resizing the SSD persistent disk can be done without stopping the virtual machine, which aligns with the requirement that the VM cannot be restarted until the next maintenance event1.

Cost-Effectiveness: Resizing the disk is a cost-effective solution because it does not require provisioning additional compute resources or migrating to a different database service, which could incur higher costs and complexity1.

Immediate Performance Boost: The performance improvement is immediate after the disk resize, as the database can utilize the additional space for better disk I/O performance, which is often a bottleneck in database operations1.

Answer : B

The decision to take the website and database server offline falls under the Containment phase of the incident response lifecycle. Here's how the process typically unfolds:

Detection: The incident response team detects a potential security breach, such as an SQL injection attack, through network access logs using SIEM.

Analysis: The team analyzes the incident to confirm the breach and understand its scope and impact.

Containment: Once confirmed, the team moves to contain the incident to prevent further damage. This includes making the affected website and database server offline to stop the attack from spreading or causing more harm1.

Eradication and Recovery: After containment, the team works on eradicating the threat and recovering the systems to normal operation.

Post-Incident Activity: Finally, the team conducts a post-mortem analysis to learn from the incident and improve future response efforts.

Reference: The containment phase is critical in incident response as it aims to limit the damage of the security incident and isolate affected systems to prevent the spread of the attack12. Taking systems offline is a common containment strategy to ensure that attackers can no longer access the compromised systems1.

Answer : B

To disable user account passwords on an Amazon EC2 Linux instance, Simon should use the command passwd -L <USERNAME>. Here's the detailed explanation:

passwd Command: The passwd command is used to update a user's authentication tokens (passwords).

-L Option: The -L option is used to lock the password of the specified user account, effectively disabling the password without deleting the user account itself.

Security Measure: Disabling passwords ensures that the user cannot authenticate using a password, thereby enhancing the security of the instance.

Answer : C

In a VMware virtualization environment, to connect a virtual machine (VM) directly to a Logical Unit Number (LUN) and access it from a Storage Area Network (SAN), the appropriate storage option is Raw Device Mapping (RDM), which is also referred to as Raw Storage.

Raw Device Mapping (RDM): RDM is a feature in VMware that allows a VM to directly access and manage a storage device. It provides a mechanism for a VM to have direct access to a LUN on the SAN1.

LUN Accessibility: By using RDM, Elaine can map a SAN LUN directly to a VM. This allows the VM to access the LUN at a lower level than the file system, which is necessary for certain data-intensive operations2.

Disaster Recovery Automation: RDM can be particularly useful in disaster recovery scenarios where direct access to the storage device is required for replication or other automation workflows1.

VMware Compatibility: RDM is compatible with VMware vSphere and is commonly used in environments where control over the storage is managed at the VM level1.

Reference: Connecting a VM directly to a LUN using RDM is a common practice in VMware environments, especially when there is a need for storage operations that require more control than what is provided by file-level storage. It is a suitable option for organizations looking to extend their storage capacity and automate disaster recovery workflows12.

Answer : C

Azure Activity Logs provide a record of operations performed on resources within an Azure subscription. They are essential for monitoring and auditing purposes, as they offer detailed information on the operations, including the timestamp, status, and the identity of the user responsible for the operation.

Here's how Azure Activity Logs can be utilized by Alice:

Recording Operations: Azure Activity Logs record all control-plane activities, such as creating, updating, and deleting resources through Azure Resource Manager.

Evidence Collection: For forensic purposes, these logs are crucial as they provide evidence of the operations performed on specific resources.

Syncing Logs: Azure Activity Logs can be integrated with Azure services for better monitoring and can be synced with other tools for analysis.

Access and Management: Investigators like Alice can access these logs through the Azure portal, Azure CLI, or Azure Monitor REST API.

Security and Compliance: These logs are also used for security and compliance, helping organizations to meet regulatory requirements.

Answer : A

Azure Information Protection (AIP) is a cloud-based solution that helps organizations classify and protect documents and emails by applying labels. AIP can be used to protect both data at rest and in transit, making it suitable for securely sharing classified information.

Here's how AIP secures document sharing:

Classification and Labeling: AIP allows administrators to classify data based on sensitivity and apply labels that carry protection settings.

Protection: It uses encryption, identity, and authorization policies to protect documents and emails.

Access Control: Only authorized users with the right permissions can access protected documents, even if the document is shared outside the organization.

Tracking and Revocation: Administrators can track activities on shared documents and revoke access if necessary.

Integration: AIP integrates with other Microsoft services and applications, ensuring a seamless protection experience across the organization's data ecosystem.
