質問 # 62
What is the primary role of Identity and Access Management (IAM)?
- A. To monitor and log all user activities and traffic
- B. Ensure all users have the same level of access
- C. To encrypt data at rest and in transit
- D. Ensure only authorized entities access resources
正解：D
解説：
The primary role of Identity and Access Management (IAM) is to control and manage who has access to cloud resources and ensure that only authorized users, systems, or entities are granted access. IAM involves the creation, management, and enforcement of policies that define user identities and their corresponding permissions to access specific resources. This helps prevent unauthorized access and ensures that security policies are properly enforced.
While encryption and activity monitoring are important security practices, they are not the primary focus of IAM. Similarly, IAM is about assigning appropriate access levels based on roles and needs, not ensuring all users have the same level of access.
質問 # 63
Which cloud security model type provides generalized templates for helping implement cloud security?
- A. Conceptual models or frameworks
- B. Cloud Controls Matrix (CCM)
- C. Reference architectures
- D. Controls models or frameworks

The characteristics and traits of an individual that when aggregated could reveal the identity of that person. are known as:
- A. Indirect identifications
- B. Indirect Identifiers
- C. Indirect indicators
- D. Indirect Identity Marks
正解：B
解説：
Indirect identifiers typically consist of demographic or socioeconomic information, dates, or events.
Although each standalone indirect identifier cannot identify the individual, the risk is that combining a number of indirect identifiers with external data can result in exposing the subject of the information.
For example, imagine a scenario in which users were able to combine search engine data, coupled with online streaming recommendations to tie back posts and recommendations to individual users on a website.

質問 # 69
Which technique involves assessing potential threats through analyzing attacker capabilities, motivations, and potential targets?
- A. Threat modeling
- B. Vulnerability assessment
- C. Risk assessment
- D. Incident response
正解：A
解説：
Threat modeling is the technique used to assess potential threats by analyzing attacker capabilities, motivations, and potential targets. It involves identifying, understanding, and prioritizing potential security threats in the context of a system or application. By considering the attackers' possible objectives and methods, organizations can design security controls to mitigate these risks proactively.
Vulnerability assessment focuses on identifying and evaluating vulnerabilities in a system, but it does not explicitly analyze attacker behavior or motivations. Incident response involves responding to security incidents after they occur, not proactively assessing potential threats. Risk assessment involves evaluating potential risks to an organization, but threat modeling specifically focuses on understanding and mitigating potential threats, making it a more targeted technique for this purpose.
質問 # 70
Which is the most important trust mechanism between cloud service provider and cloud customer?
- A. Logging and Monitoring reports
- B. Meeting SLA requirements
- C. Audit reports
- D. Contract
正解：D
解説：
Contract is the most important document which defines trust and relationship between cloud service provider and the customer.
質問 # 71
As with security. compliance in the cloud is a shared responsibility model.
- A. True
- B. False
正解：A
解説：
As with security. compliance in the cloud is a shared responsibility model. Both the cloud provider and customer have responsibilities. But the customer is always ultimately responsible for their own compliance. These responsibilities are defined through contracts, audits/assessments. and specifics of the compliance requirements.

質問 # 73
Which of the following is an effective way of segregating different cloud networks and datacenters in a hybrid cloud environment?
- A. Virtual LANs
- B. Virtual Private Networks
- C. Dedicated Hosting
- D. Bastion Virtual Network
正解：D
解説：
One emerging architecture for hybrid cloud connectivity is "bastion" or "transit" virtual networks:
. This scenario allows you to connect multiple, different cloud networks to a data center using a single hybrid connection. The cloud user builds a dedicated virtual network for the hybrid connection and then peers any other networks through the designated bastion network.
. Second-level networks connect to the data center through the bastion network, but since they aren't peered to each other they can't talk to each other and are effectively segregated. Also, you can deploy different security tools, firewall rulesets, and Access Control Lists in the bastion network to further protect traffic in and out of the hybrid connection.

- C. The possibility of data crossing geographic or jurisdictional boundaries.
- D. The on demand self-service nature of cloud computing environments.
- E. Object-based storage in a private cloud.
正解：A
質問 # 75
Which type of controls should be implemented when required controls for a cybersecurity framework cannot be met?
- A. Detective controls
- B. Preventive controls
- C. Administrative controls
- D. Compensating controls
正解：D
解説：
Compensating controls are implemented when the required controls for a cybersecurity framework cannot be met due to technical or practical limitations. These controls are alternative measures that provide similar protection or risk mitigation. Compensating controls help to ensure that the security posture remains strong even when the primary controls cannot be applied.
Detective controls focus on identifying security incidents after they occur but do not replace required controls.
Preventive controls aim to prevent security incidents from occurring but may not always be possible or practical to implement in certain situations. Administrative controls include policies and procedures but do not address the need for compensating measures when technical controls cannot be met.

質問 # 80
Which of the authentication is more secured?
- A. Password Authentication
- B. Multifactor Authentication
- C. Biometric Authentication
- D. Single Sign-on
正解：B
解説：
Multifactor authentication is more secured than the rest because it has more than one aspect to authentication Multifactor authentication is composed of, at a minimum, two of the following aspects- something you know, something you are, or something you have. Something you know can be a password, passphrase, and so on. Something you have can be something like a number-generating transmit a number or fob, a smartphone capable of receiving text messages, or even a phone that can receive a call and then to the individual but that is only accessible from a very specific phone number.
Something you are is a biometric trait of yourself, as a living creature. This could be as unique and specific as your DNA fingerprint, or as cursorily general as a photograph.
