CompTIA CompTIA Certifications CAS-004 Questions & Answers

• Question 661:

  Which of the following terms refers to the delivery of encryption keys to a CASB or a third-party entity?

  A. Key sharing

  B. Key distribution

  C. Key recovery

  D. Key escrow

  Correct Answer: B

  The term is actually key distribution key word distribution = delivery. Key Escrow is the process to store the key. Totally use key Escrow with CASB and third party but the deliver system is Key Distribution. In short escrow is method of storing and distribution is method of delivery. https://csrc.nist.gov/glossary/term/key_distribution https://jumpcloud.com/blog/key-escrow

• Question 666:

  During a remodel, a company's computer equipment was moved to a secure storage room with cameras positioned on both sides of the door. The door is locked using a card reader issued by the security team, and only the security team and department managers have access to the room. The company wants to be able to identify any unauthorized individuals who enter the storage room by following an authorized employee.

  Which of the following processes would BEST satisfy this requirement?

  A. Monitor camera footage corresponding to a valid access request.

  B. Require both security and management to open the door.

  C. Require department managers to review denied-access requests.

  D. Issue new entry badges on a weekly basis.

  Correct Answer: A

• Question 667:

  A company created an external application for its customers. A security researcher now reports that the application has a serious LDAP injection vulnerability that could be leveraged to bypass authentication and authorization. Which of the following actions would BEST resolve the issue? (Choose two.)

  A. Conduct input sanitization.

  B. Deploy a SIEM.

  C. Use containers.

  D. Patch the OS

  E. Deploy a WAF.

  F. Deploy a reverse proxy

  G. Deploy an IDS.

  Correct Answer: AE

  A WAF protects your web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application, and prevents any unauthorized data from leaving the app. It does this by adhering to a set of policies that help determine what traffic is malicious and what traffic is safe.

• Question 668:

  In preparation for the holiday season, a company redesigned the system that manages retail sales and moved it to a cloud service provider. The new infrastructure did not meet the company's availability requirements. During a postmortem analysis, the following issues were highlighted:

  1.

  International users reported latency when images on the web page were initially loading.

  2.

  During times of report processing, users reported issues with inventory when attempting to place orders.

  3.

  Despite the fact that ten new API servers were added, the load across servers was heavy at peak times.

  Which of the following infrastructure design changes would be BEST for the organization to implement to avoid these issues in the future?

  A. Serve static content via distributed CDNs, create a read replica of the central database and pull reports from there, and auto-scale API servers based on performance.

  B. Increase the bandwidth for the server that delivers images, use a CDN, change the database to a non-relational database, and split the ten API servers across two load balancers.

  C. Serve images from an object storage bucket with infrequent read times, replicate the database across different regions, and dynamically create API servers based on load.

  D. Serve static-content object storage across different regions, increase the instance size on the managed relational database, and distribute the ten API servers across multiple regions.

  Correct Answer: A

  Serving static content via distributed Content Delivery Networks (CDNs) can reduce latency for international users because it serves content from the closest geographic location to the user.

  Creating a read replica of the central database and pulling reports from there can reduce the load on the central database, minimizing disruptions to inventory lookups during report processing.

  Auto-scaling API servers based on performance can ensure that as load increases, new servers are spun up to handle it, distributing the load more evenly and preventing any single server from becoming overloaded.

  The other options offer some potential improvements but don't address all of the identified issues as effectively.

• Question 669:

  An organization is preparing to migrate its production environment systems from an on-premises environment to a cloud service. The lead security architect is concerned that the organization's current methods for addressing risk may not be possible in the cloud environment.

  Which of the following BEST describes the reason why traditional methods of addressing risk may not be possible in the cloud?

  A. Migrating operations assumes the acceptance of all risk.

  B. Cloud providers are unable to avoid risk.

  C. Specific risks cannot be transferred to the cloud provider.

  D. Risks to data in the cloud cannot be mitigated.

  Correct Answer: C

  A makes no sense since the CSP isn't the data owner

  B: Cloud providers could avoid the risk via contract

  C: Cloud migrations are always a shared risk responsibility but ultimately the data owner/user has the most risk because they have the most to lose.

  D: You can mitigate risks with technical and administrative controls in both cloud and on-premises

• Question 670:

  An organization is referencing NIST best practices for BCP creation while reviewing current internal organizational processes for mission-essential items. Which of the following phases establishes the identification and prioritization of critical systems and functions?

  A. Review a recent gap analysis.

  B. Perform a cost-benefit analysis.

  C. Conduct a business impact analysis.

  D. Develop an exposure factor matrix.

  Correct Answer: C

  A business impact analysis (BIA) is a key component of business continuity planning that identifies critical systems and functions and assesses the potential impact of various disaster scenarios. By conducting a BIA, an organization can determine which systems and functions are most critical and prioritize them for recovery in the event of a disruption.
