Q 151: B doesn't make sense to me as an access badge can be lost/stolen. Wouldn't vid surveillance be a better solution? unless "secure" is the key word here. vid surveillance then doesn't "secure" anything it is more of a deter/monitor solution.... I guess I answered my own question...

208:Based on the scenario described—where an application server's software is behaving abnormally by generating unexpected outbound traffic over random high ports—the most likely exploited vulnerability is: Memory Injection (e.g., Buffer Overflow or Code Injection) Why? Abnormal process behavior (unexpected network traffic) suggests execution of malicious code injected into the software’s memory. Random high ports are commonly used by malware for command-and-control (C2) communication or data exfiltration. Memory-based attacks (e.g., buffer overflows, ROP attacks) can hijack a legitimate process to execute attacker-controlled payloads. Why Not the Others? Race Condition Causes timing-related exploits (e.g., TOCTOU attacks) but does not typically generate network traffic. Would lead to logic errors, not outbound connections. Side Loading Involves loading malicious DLLs/libraries, but this usually happens at startup, not mid-execution. More common in Windows environments (e.g.,

194: To ensure the organization follows security best practices when transitioning an on-premises application to a cloud-based service, the security team should implement all of the listed controls, as they address different critical aspects of cloud security. However, if prioritizing the most fundamental requirement for a secure cloud deployment, the team should first ensure: 1. Virtualization and Isolation of Resources Why? Cloud environments rely on multi-tenancy, so virtualization and isolation prevent cross-tenant attacks (e.g., VM escapes, side-channel attacks). Best Practice: Use hypervisor security, container isolation, and micro-segmentation to enforce strict boundaries between workloads. Supporting Controls (Also Critical but Secondary to Core Isolation): 2. Network Segmentation Limits lateral movement if a breach occurs (e.g., separating frontend/backend tiers). However, isolation at the virtualization layer is more foundational in cloud environments. 3. Data Encryption

for Q483 The company needs to run a Windows containerized .NET 6 job every 10 minutes, with a runtime varying between 1 and 3 minutes, in the AWS Cloud, and do so MOST cost-effectively. Let's evaluate each solution: Create an AWS Lambda function based on the container image of the job. Configure Amazon EventBridge to invoke the function every 10 minutes. AWS Lambda for containers: Lambda now supports deploying functions as container images, including Windows containers. This is a serverless option, meaning you don't manage any servers. Runtime limits: AWS Lambda functions have a maximum runtime of 15 minutes. Since the job runs between 1 and 3 minutes, it fits well within this limit. Cost-effectiveness: Lambda's pricing model is based on duration and memory consumed, billed in millisecond increments. You only pay when your code is running. For a job running only 1-3 minutes every 10 minutes, this is incredibly cost-effective because you pay almost nothing for idle time. EventBridg

Question 77: Answer should be all Bulk copy from an External Stage: This involves using the COPY INTO command to load data from files stored in external cloud storage locations (e.g., Amazon S3, Azure Blob Storage, Google Cloud Storage) into a Snowflake table. Continuous load using Snowpipe REST API: Snowpipe enables continuous data loading from staged files as soon as they become available. The Snowpipe REST API can be used to trigger the loading process for new files in an external stage. The Snowflake Web Interface (UI) data loading wizard: Snowsight, Snowflake's web interface, provides a user-friendly wizard that guides users through the process of loading data into tables, often from local files or staged files. Bulk copy from an Internal Stage: Similar to external stages, data can be bulk loaded from internal stages (storage locations within Snowflake) into tables using the COPY INTO command. Files can be placed in internal stages using commands like PUT.

Question 68: Explanation: INSERT: When inserting data into a table, Snowflake usually writes to new partitions, allowing other queries to access the existing data simultaneously. COPY: Similar to INSERT, the COPY command often writes to new partitions, enabling parallel execution with other operations. Why other options are incorrect: UPDATE: This command modifies existing data in a table, which requires locking the affected rows to prevent conflicts. This makes it a blocking operation, meaning other queries that need to access the same rows will have to wait until the UPDATE finishes. MERGE: Like UPDATE, the MERGE command modifies data in a table, requiring locks and thus being a blocking operation. It combines data from multiple sources into a target table, which can involve modifying existing rows.
