NEW QUESTION # 233
A small company needs to reduce its operating costs. vendors have proposed solutions, which all focus on management of the company's website and services. The Chief information Security Officer (CISO) insist all available resources in the proposal must be dedicated, but managing a private cloud is not an option. Which of the following is the BEST solution for this company?
- A. Community cloud service model
- B. Single-tenancy SaaS
- C. Multinency SaaS
- D. On-premises cloud service model
Answer: B
Explanation:
A single-tenancy SaaS solution is the best solution for this company. SaaS stands for software as a service, which is a cloud-based model that allows customers to access applications hosted by a provider over the internet. A single-tenancy SaaS solution means that the company has its own dedicated instance of the application and its underlying infrastructure, which offers more control, customization, and security than a multi-tenancy SaaS solution where multiple customers share the same resources. A single-tenancy SaaS solution also eliminates the need for managing a private cloud or an on-premises infrastructure.

NEW QUESTION # 237
An administrator at a software development company would like to protect the integrity of the company's applications with digital signatures. The developers report that the signing process keeps failing on all applications. The same key pair used for signing, however, is working properly on the website, is valid, and is issued by a trusted CA. Which of the following is MOST likely the cause of the signature failing?
- A. The certificate is set for the wrong key usage.
- B. The CA has included the certificate in its CRL.
- C. The NTP server is set incorrectly for the developers
- D. Each application is missing a SAN or wildcard entry on the certificate
Answer: A
Explanation:
The most likely cause of the signature failing is that the certificate is set for the wrong key usage. Key usage is an extension of a certificate that defines the purpose and functionality of the public key contained in the certificate. Key usage can include digital signature, key encipherment, dataencipherment, certificate signing, and others. If the certificate is set for a different key usage than digital signature, it will not be able to sign the applications properly. The administrator should check the key usage extension of the certificate and make sure it matches the intended purpose. Verified References:

NEW QUESTION # 238
A security architect was asked to modify an existing internal network design to accommodate the following requirements for RDP:
* Enforce MFA for RDP
* Ensure RDP connections are only allowed with secure ciphers.
The existing network is extremely complex and not well segmented. Because of these limitations, the company has requested that the connections not be restricted by network-level firewalls Of ACLs.
Which of the following should the security architect recommend to meet these requirements?
- A. Implement a remote desktop gateway server, enforce secure ciphers, and configure to use OTP
- B. Implement a GPO that enforces TLS cipher suites and limits remote desktop access to only VPN users.
- C. Implement a bastion host with a secure cipher configuration enforced.
- D. Implement a reverse proxy for remote desktop with a secure cipher configuration enforced.
Answer: A
Explanation:
A remote desktop gateway server is a solution that allows users to connect to remote desktops or applications over the internet using the Remote Desktop Protocol (RDP). A remote desktop gateway server can enforce MFA for RDP by integrating with Azure AD MFA using the Network Policy Server (NPS) extension. The NPS extension can send an OTP (one-time password) to the user's phone or mobile app as a second factor of authentication. A remote desktop gateway server can also enforce secure ciphers by configuring the SSL Cipher Suite Order Group Policy setting to specify the preferred order of cipher suites for TLS/SSL connections.

Which of the following should the security analyst perform?
- A. Block the IP address for the business partner at the perimeter firewall.
- B. Configure the email gateway to automatically quarantine all messages originating from the business partner.
- C. Contact the security department at the business partner and alert them to the email event.
- D. Pull the devices of the affected employees from the network in case they are infected with a zero-day virus.
Answer: C
Explanation:
The best option for the security analyst to perform is to contact the security department at the business partner and alert them to the email event. The email appears to be a phishing attempt that tries to trick the employees into revealing their login credentials by impersonating a legitimate sender. The security department at the business partner should be notified so they can investigate the source and scope of the attack and take appropriate actions to protect their systems and users.

NEW QUESTION # 241
A security engineer needs to recommend a solution that will meet the following requirements:
Identify sensitive data in the provider's network
Maintain compliance with company and regulatory guidelines
Detect and respond to insider threats, privileged user threats, and compromised accounts Enforce datacentric security, such as encryption, tokenization, and access control Which of the following solutions should the security engineer recommend to address these requirements?
- A. WAF
- B. CASB
- C. SWG
- D. DLP
Answer: D
Explanation:
DLP (data loss prevention) is a solution that can meet the following requirements: identify sensitive data in the provider's network, maintain compliance with company and regulatory guidelines, detect and respond to insider threats, privileged user threats, and compromised accounts, and enforce data-centric security, such as encryption, tokenization, and access control. DLP can monitor, classify, and protect data in motion, at rest, or in use, and prevent unauthorized disclosure or exfiltration. WAF (web application firewall) is a solution that can protect web applications from common attacks, such as SQL injection or cross-site scripting, but it does not address the requirements listed. CASB (cloud access security broker) is a solution that can enforce policies and controls for accessing cloud services and applications, but it does not address the requirements listed. SWG (secure web gateway) is a solution that can monitor and filter web traffic to prevent malicious or unauthorized access, but it does not address the requirements listed.

A company requires a task to be carried by more than one person concurrently. This is an example of:
- A. dual control
- B. least privilege
- C. separation of d duties.
- D. job rotation
Answer: A
Explanation:
Dual control is a security principle that requires two or more authorized individuals to perform a task concurrently. This reduces the risk of fraud, error, or misuse of sensitive assets or information. Verified References: https://www.comptia.org/training/books/casp-cas-004-study-guide , https://www.isaca.org

NEW QUESTION # 243
A company wants to prevent a partner company from denying agreement to a transaction. Which of the following is the best solution for the company?
- A. Federation
- B. Salting hashes
- C. Digital signatures
- D. Key escrow
Answer: C
Explanation:
Step by Step Explanation:
Digital signatures provide non-repudiation, ensuring that the sender cannot deny signing a transaction. This mechanism ties the transaction to the entity through cryptographic assurance.
Federation involves identity management and authentication but does not address non-repudiation.
Key escrow is used for securely storing encryption keys and is unrelated to transaction agreements.
Salting hashes enhances password security but does not support transactional non-repudiation.
Reference: CASP+ Exam Objectives 2.3 - Apply cryptographic techniques to ensure non-repudiation.
NEW QUESTION # 244
Real-time, safety-critical systems MOST often use serial busses that:
- A. have deterministic behavior and are not deployed with encryption.
- B. have non-deterministic behavior and are deployed with encryption.
- C. have non-deterministic behavior and are not deployed with encryption.
- D. have deterministic behavior and are deployed with encryption.
Answer: A
Explanation:
For safety-critical systems, CAN is the most widely used communication protocol and does not have a built-in encryption mechanism. This prioritizes low latency and deterministic response times over encryption.
NEW QUESTION # 245
A shipping company that is trying to eliminate entire classes of threats is developing an SELinux policy to ensure its custom Android devices are used exclusively for package tracking.
After compiling and implementing the policy, in which of the following modes must the company ensure the devices are configured to run?
- A. Protecting
- B. Enforcing
- C. Mandatory
- D. Permissive
Answer: B
Explanation:
Reference: https://source.android.com/security/selinux/customize
SELinux (Security-Enhanced Linux) is a security module for Linux systems that provides mandatory access control (MAC) policies for processes and files. SELinux can operate in three modes:
Enforcing: SELinux enforces the MAC policies and denies access based on rules.
Permissive: SELinux does not enforce the MAC policies but only logs actions that would have been denied if running in enforcing mode.
Disabled: SELinux is turned off.
To ensure its custom Android devices are used exclusively for package tracking, the company must configure SELinux to run in enforcing mode. This mode will prevent any unauthorized actions or applications from running on the devices and protect them from potential threats or misuse. References:
