NEW QUESTION # 27
Which of the following is a key principle of ZT and is required for its implementation?
- A. Making no assumptions about an entity's trustworthiness when it
requests access to a resource - B. Implementing strong anti-phishing email filters
- C. Encrypting all communications between any two endpoints
- D. Requiring that authentication and explicit authorization must occur
after network access has been granted
Answer: A
Explanation:
Explanation
One of the core principles of Zero Trust (ZT) is to "never trust, always verify" every request for access to a resource, regardless of where it originates or what resource it accesses1. This means that ZT does not rely on implicit trust based on network perimeters, device types, or user roles, but rather on explicit verification based on multiple data points, such as user identity, device health, location, service, data classification, and anomalies1.

NEW QUESTION # 30
Of the following options, which risk/threat does SDP mitigate by
mandating micro-segmentation and implementing least privilege?
- A. Security logging and monitoring failures
- B. Injection
- C. Identification and authentication failures
- D. Broken access control
Answer: D
Explanation:
Explanation
SDP mitigates the risk of broken access control by mandating micro-segmentation and implementing least privilege. Micro-segmentation divides the network into smaller, isolated segments that can prevent unauthorized access and contain lateral movement. Least privilege grants the minimum necessary access to users and devices for specific resources, while hiding all other assets from their view. This reduces the attack surface and prevents attackers from exploiting weak or misconfigured access controls
NEW QUESTION # 31
When planning for ZT implementation, who will determine valid
users, roles, and privileges for accessing data as part of data
governance?
- A. IT teams
- B. Compliance officers
- C. Application owners
- D. Asset owners
Answer: D
Explanation:
Explanation
Asset owners are the ones who will determine valid users, roles, and privileges for accessing data as part of data governance. Asset owners are responsible for defining the data classification, sensitivity, and ownership of the data assets they own. They also have the authority to grant or revoke access to the data assets based on the business needs and the Zero Trust policies.

NEW QUESTION # 32
Which of the following is a required concept of single packet
authorizations (SPAs)?
- A. An SPA packet must be digitally signed and authenticated.
- B. Upon receiving an SPA, a server must respond to establish secure connectivity.
- C. An SPA header is encrypted and thus trustworthy.
- D. An SPA packet must self-contain all necessary information.
Answer: A
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.

How can device impersonation attacks be effectively prevented in a
ZTA?
- A. Organizational asset management
- B. Single packet authorization (SPA)
- C. Micro-segmentation
- D. Strict access control
Answer: B
Explanation:
Explanation
SPA is a security protocol that prevents device impersonation attacks in a ZTA by hiding the network infrastructure from unauthorized and unauthenticated users. SPA uses a single encrypted packet to convey the user's identity and request access to a resource. The SPA packet must be digitally signed and authenticated by the SPA server before granting access. This ensures that only authorized devices can send valid SPA packets and prevents spoofing, replay, or brute-force attacks12.

NEW QUESTION # 34
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) Discovery (2) Mapping access controls and network assets
- C. (1) Never trusting (2) Reducing the attack surface
- D. (1) Authentication (2) Authorization of all networked assets
Answer: C
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.

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 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. - B. 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. - C. 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. - D. ZTA policies should primarily educate users about secure practices
and promote strong authentication for services accessed via mobile
devices to prevent data compromise.
Answer: B
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 # 42
In a ZTA, what is a key difference between a policy decision point
(PDP) and a policy enforcement point (PEP)?
- A. A PDP measures incoming control plane authentication signals. A
PEP measures incoming data plane authorization signals. - B. A PDP measures incoming signals against a set of access
determination criteria. A PEP uses incoming signals to open or close a
connection. - C. A PDP measures incoming signals in an untrusted zone. A PEP
measures incoming signals in an implicit trust zone. - D. A PDP measures incoming signals and makes dynamic risk
determinations. A PEP uses incoming signals to make static risk
determinations.
Answer: B
Explanation:
Explanation
In a ZTA, a policy decision point (PDP) is a logical component that evaluates the incoming signals from an entity requesting access to a resource against a set of access determination criteria, such as identity, context, device, location, and behavior1. A PDP then makes a decision to grant or deny access, or to request additional information or verification, based on the policies defined by the policy administrator1. A policy enforcement point (PEP) is a logical component that uses the incoming signals from the PDP to open or close a connection between the entity and the resource1. A PEP acts as a gateway or intermediary that enforces the decision made by the PDP and prevents unauthorized or risky access2.

ZTA reduces management overhead by applying a consistent
access model throughout the environment for all assets. What can
be said about ZTA models in terms of access decisions?
- A. The traffic of the access workflow must contain all the parameters
for the policy enforcement points. - B. Access revocation data will be passed from the policy decision
points to the policy enforcement points. - C. The traffic of the access workflow must contain all the parameters
for the policy decision points. - D. Each access request is handled just-in-time by the policy decision
points.
Answer: D
Explanation:
Explanation
ZTA models in terms of access decisions are based on the principle of "never trust, always verify", which means that each access request is handled just-in-time by the policy decision points. The policy decision points are the components in a ZTA that evaluate the policies and the contextual data collected from various sources, such as the user identity, the device posture, the network location, the resource attributes, and the environmental factors, and then generate an access decision. The access decision is communicated to the policy enforcement points, which enforce the decision on the resource. This way, ZTA models apply a consistent access model throughout the environment for all assets, regardless of their location, type, or ownership.

inside and outside the network?
- A. Requiring continuous monitoring
- B. Assume breach
- C. Scrutinize explicitly
- D. Assume a hostile environment
Answer: B
Explanation:
Explanation
The ZT tenet of assume breach is based on the notion that malicious actors reside inside and outside the network, and that any user, device, or service can be compromised at any time. Therefore, ZT requires continuous verification and validation of all entities and transactions, and does not rely on implicit trust or perimeter-based defenses
