Q1. Which category of secondary data store does a content delivery network (CDN) best represent?
Correct answer: D. Replica
Replicas enhance reliability and fault tolerance by duplicating data across multiple storage devices in different locations. CDNs are a real-world application of this concept, distributing assets such as video and static web content to improve delivery performance. Network attached storage (NAS) is a file-sharing technology not inherently tied to secondary storage. Synthetic may refer to concepts like synthetic testing or synthetic full backups. Differential describes a backup approach that captures changes made since the most recent full backup.
Q2. A systems administrator enables hyperthreading on a server. For each physical processor core, how many logical cores will the operating system detect?
Correct answer: A. 2
Hyperthreading technology enables one physical core to appear as two separate logical cores to the operating system, effectively doubling the visible processor count.
Q3. A humidity sensor embedded in a building transmits readings over the network to a public cloud platform. Which technology category does this device belong to?
Correct answer: D. IoT
Internet of Things (IoT) refers to network-connected devices whose primary function is something other than general-purpose computing. Typical examples include smart sensors, cameras, and embedded control systems. A cloud service provider (CSP) is the entity delivering cloud resources. Maximum transmission unit (MTU) is a network configuration parameter. MQTT is a lightweight publish/subscribe messaging protocol commonly used by IoT devices, but it is the protocol, not the device category.
Q4. A solid-state drive is attached to a server via a SCSI interface. Which storage classification does this represent?
Correct answer: B. DAS
Direct-attached storage (DAS) refers to storage media connected directly to a host via a physical interface such as SCSI or SATA. Cloud environments sometimes provision DAS for ephemeral workloads. Network-attached storage (NAS) is accessed over a TCP/IP network rather than a direct physical link. SATA is an interface standard used for one form of direct attachment. iSATA is a fabricated distractor with no standard definition.
Q5. A security tester at a company attempts to log in to a cloud web server by trying default credentials and commonly used passwords. All login attempts are unsuccessful. Which type of security testing is this MOST consistent with?
Correct answer: A. Penetration
Penetration testing involves actively attempting to exploit weaknesses in a system, typically from an outsider perspective without prior credentials. Trying weak or default passwords is a standard penetration testing technique. Vulnerability testing focuses on identifying potential weaknesses using scanning tools rather than active exploitation; no scanner is mentioned here. Regression testing verifies that system changes have not introduced new defects, which does not apply to this scenario. Functional testing validates expected application behavior against a defined specification.
Q6. A streaming platform recommends videos based on a user's watch history, and the recommendations improve over time as more viewing and rating data is collected. Which technology is MOST likely powering this feature?
Correct answer: A. ML
Recommendation engines that learn from historical user behavior are a classic machine learning (ML) use case. MTU is a network configuration value. REST is a widely adopted architectural style for building APIs. Serverless computing abstracts all underlying infrastructure so that code functions execute on demand without managing servers.
Q7. A provider delivers accounting software to customers via the Internet. The provider owns and manages all hardware, hypervisors, operating systems, databases, and patching. Customers are only responsible for managing their own user accounts. Which cloud service model does this describe?
Correct answer: C. SaaS
Software as a Service (SaaS) places the maximum operational burden on the cloud provider. The provider handles infrastructure, hypervisors, operating systems, and application maintenance. Consumers typically only manage their own data and user accounts. Under Infrastructure as a Service (IaaS), the consumer would be responsible for operating systems and databases. Public and private cloud are deployment models, not service models.
Q8. A cloud storage platform enforces a 50 GB per-user limit for its basic plan. A user who has already stored 50 GB uploads an additional 3 GB file. The upload completes successfully, but the user receives a warning that they have exceeded their allotment. What term BEST describes this type of limit?
Correct answer: D. Soft limit
A soft limit permits an action to proceed even when the threshold is crossed, but typically triggers a warning or notification. A hard limit blocks the action entirely once the threshold is reached. Quotas define how a host allocates resources to guests rather than governing the outcome of an action.
Q9. An accounting company based in the European Union wants to replicate data to datacenters on multiple continents. Which of the following could MOST likely prevent this from happening?
Correct answer: B. Regulatory requirements
Regulations such as GDPR impose data residency obligations that may restrict where personal data about EU citizens can be stored or transferred. N + 1 is a redundancy model designed to tolerate a single component failure. EIA/TIA 568 is a structured cabling specification. VT-x is an Intel CPU virtualization feature unrelated to data residency.
Q10. A server stores data on SSDs and has 128 GB of RAM. The organization encrypts data at rest following standard practices. At which point in the write process is the data encrypted?
Correct answer: C. Before it is written to the SSD
Encryption at rest means data is encrypted prior to being committed to persistent storage. SSDs and HDDs are forms of persistent storage. RAM is volatile memory, not storage, so it is not within scope for encryption at rest.
