NEW QUESTION # 39
Scenario: A multinational org uses ZTA to enhance security. They
collaborate with third-party service providers for remote access to
specific resources. How can ZTA policies authenticate third-party
users and devices for accessing resources?
- A. ZTA policies can be configured to authenticate third-party users
and their devices, determining the necessary access privileges for
resources while concealing all other assets to minimize the attack
surface. - B. ZTA policies should prioritize securing remote users through
technologies like virtual desktop infrastructure (VDI) and corporate
cloud workstation resources to reduce the risk of lateral movement via
compromised access controls. - C. ZTA policies should primarily educate users about secure practices
and promote strong authentication for services accessed via mobile
devices to prevent data compromise. - D. ZTA policies can implement robust encryption and secure access
controls to prevent access to services from stolen devices, ensuring
that only legitimate users can access mobile services.
Answer: A
Explanation:
Explanation
ZTA is based on the principle of never trusting any user or device by default, regardless of their location or ownership. ZTA policies can use various methods to verify the identity and context of third-party users and devices, such as tokens, certificates, multifactor authentication, device posture assessment, etc. ZTA policies can also enforce granular and dynamic access policies that grant the minimum necessary privileges to third-party users and devices for accessing specific resources, while hiding all other assets from their view.
This reduces the attack surface and prevents unauthorized access and lateral movement within the network.

NEW QUESTION # 43
In SaaS and PaaS, which access control method will ZT help define
for access to the features within a service?
- A. Attribute-based access control (ABAC)
- B. Data-based access control (DBAC)
- C. Privilege-based access control (PBAC)
- D. Role-based access control (RBAC)
Answer: A
Explanation:
Explanation
ABAC is an access control method that uses attributes of the requester, the resource, the environment, and the action to evaluate and enforce policies. ABAC allows for fine-grained and dynamic access control based on the context of the request, rather than predefinedroles or privileges. ABAC is suitable for SaaS and PaaS, where the features within a service may vary depending on the customer's needs, preferences, and subscription level. ABAC can help implement ZT by enforcing the principle of least privilege and verifying every request based on multiple factors.

NEW QUESTION # 44
Which of the following is a required concept of single packet
authorizations (SPAs)?
- A. Upon receiving an SPA, a server must respond to establish secure connectivity.
- B. An SPA header is encrypted and thus trustworthy.
- C. An SPA packet must be digitally signed and authenticated.
- D. An SPA packet must self-contain all necessary information.
Answer: C
Explanation:
Explanation
Single Packet Authorization (SPA) is a security protocol that allows a user to access a secure network without the need to enter a password or other credentials. Instead, it is an authentication protocol that uses a single packet - an encrypted packet of data - to convey a user's identity and request access1. A key concept of SPA is that the SPA packet must be digitally signed and authenticated by the SPA server before granting access to the user. This ensures that only authorized users can send valid SPA packets and prevents replay attacks, spoofing attacks, or brute-force attacks23.

NEW QUESTION # 54
Optimal compliance posture is mainly achieved through two key ZT
features:_____ and_____
- A. (1) Principle of least privilege (2) Verifying remote access
connections - B. (1) Never trusting (2) Reducing the attack surface
- C. (1) Discovery (2) Mapping access controls and network assets
- D. (1) Authentication (2) Authorization of all networked assets
Answer: B
Explanation:
Explanation
Optimal compliance posture is mainly achieved through two key ZT features: never trusting and reducing the attack surface. Never trusting means that no entity or resource is assumed to be trustworthy or secure by default, and that every request for access or transaction is verified and validated before granting access or allowing the transaction. Reducing the attack surface means that the exposure and vulnerability of the assets and resources are minimized by implementing granular and dynamic policies, controls, and segmentation.
These two features help to ensure that the organization complies with the security standards and regulations, and that the risks of breaches and incidents are reduced.
