CCSK Online Practice Questions and Answers

Correct Answer: C

Correct Answer: C

Correct Answer: A

Correct Answer: B

Containers are indeed highly portable code execution environments. Containers provide a lightweight and isolated runtime environment that encapsulates an application and its dependencies. This allows the containerized application to run consistently and reliably across different computing environments, such as development machines, testing environments, and production servers.

Containers achieve portability by bundling the application code, runtime dependencies, libraries, and configuration files into a single package. This package, known as a container image, can be easily distributed and deployed on various host systems that have a compatible container runtime, such as Docker or Kubernetes. Containers abstract away the underlying infrastructure and operating system differences, making it possible to run the same containerized application consistently across different environments.

Correct Answer: D

In the SaaS model, the cloud provider is responsible for managing and securing the underlying infrastructure, including the network, servers, storage, and physical data centers. They are also responsible for implementing security measures at the platform level, such as access controls, authentication mechanisms, and data encryption.

The cloud provider ensures the availability, scalability, and reliability of the SaaS application, as well as the protection of customer data stored within the service. They employ various security measures to safeguard against threats and vulnerabilities that could impact the SaaS environment.

Correct Answer: E

To monitor and filter data in a virtual network when traffic might not cross the physical network, you can use the following methods:

B. Route traffic to a virtual appliance on the same virtual network: You can direct the network traffic within the virtual environment to a virtual appliance, which could be a dedicated monitoring or filtering tool. This appliance can analyze and filter the traffic within the virtual network itself.

C. Route traffic to a virtual network monitoring or filtering tool on the same hardware: Virtual network monitoring or filtering tools can run on the same hardware as the virtual machines and monitor the traffic directly within the virtual environment.

Option D (A and B) suggests routing traffic to the physical network, which might not be feasible or efficient in virtualized environments where traffic often stays within the virtual network.

Correct Answer: A

A. Provider-managed and (sometimes) proxy encryption

The encryption options available for Software-as-a-Service (SaaS) consumers typically include provider-managed encryption, where the SaaS provider handles encryption and decryption of data, and sometimes proxy encryption, where the

consumer encrypts data before sending it to the SaaS application through a proxy. These options help enhance the security of data within the SaaS environment.

Option B is not accurate because SaaS encryption options might differ from those available for volume storage, object storage, or Platform-as-a-Service (PaaS).

Options C, D, and E are not specifically representative of encryption options available for SaaS consumers.

Correct Answer: D

D: Distributed data collection SegGuiV4 p.147 - Distributed data collection: Mechanisms to ingest large volumes of data, often of a streaming nature. This could be as “lightweight” as web-click streaming analytics and as complex as highly distributed scientific imaging or sensor data. Not all big data relies on distributed or streaming data collection, but it is a core big data technology.

Correct Answer: C

C. Establishing/asserting the identity to the application

Authentication is the process of verifying and confirming the identity of a user or entity attempting to access a system, application, or resource. It involves presenting credentials (such as username and password, biometric data, or digital certificates) to prove one's identity and gain access to the desired resource. The authentication component of identity, entitlement, and access management (IdEA) is responsible for validating and asserting the identity of users or entities interacting with an application or system.
