To ensure an acceptable user experience when implementing SDP, a
security architect should collaborate with IT to do what?
- A. Model and plan the user experience, client software distribution,
and device onboarding processes. - B. Build the business case for SDP, based on cost modeling and
business value. - C. Advise IT stakeholders that the security team will fully manage all
aspects of the SDP rollout. - D. Plan to release SDP as part of a single major change or a "big-bang" implementation.
Answer: A
Explanation:
Explanation
To ensure an acceptable user experience when implementing SDP, a security architect should collaborate with IT to model and plan the user experience, client software distribution, and device onboarding processes. This is because SDP requires users to install and use client software to access the protected resources, and the user experience may vary depending on the device type, operating system, network conditions, and security policies. By modeling and planning the user experience, the security architect and IT can ensure that the SDP implementation is user-friendly, consistent, and secure.

NEW QUESTION # 28
In a ZTA, automation and orchestration can increase security by
using the following means:
- A. Static application security testing (SAST) and dynamic application
security testing (DAST) - B. Infrastructure as code (laC) and identity lifecycle management
- C. Data loss prevention (DLP) and cloud security access broker (CASB)
- D. Kubernetes and docker
Answer: B
Explanation:
Explanation
In a ZTA, automation and orchestration can increase security by using the following means:
Infrastructure as code (laC): laC is a practice of managing and provisioning IT infrastructure through code, rather than manual processes or configuration tools1. laC can increase security by enabling consistent, repeatable, and scalable deployment of ZTA components, such as policies, gateways, firewalls, and micro-segments2. laC can also facilitate compliance, auditability, and change management, as well as reduce human errors and configuration drifts3.
Identity lifecycle management: Identity lifecycle management is a process of managing the creation, modification, and deletion of user identities and their access rights throughout their lifecycle4. Identity lifecycle management can increase security by ensuring that users have the appropriate level of access to resources at any given time, based on the principle of least privilege5. Identity lifecycle management can also automate the provisioning and deprovisioning of user accounts, enforce strong authentication and authorization policies, and monitor and audit user activity and behavior6.

NEW QUESTION # 32
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 signals in an untrusted zone. A PEP
measures incoming signals in an implicit trust zone. - B. A PDP measures incoming signals and makes dynamic risk
determinations. A PEP uses incoming signals to make static risk
determinations. - C. A PDP measures incoming signals against a set of access
determination criteria. A PEP uses incoming signals to open or close a
connection. - D. A PDP measures incoming control plane authentication signals. A
PEP measures incoming data plane authorization signals.
Answer: C
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.

The following list describes the SDP onboarding process/procedure.
What is the third step? 1. SDP controllers are brought online first. 2.
Accepting hosts are enlisted as SDP gateways that connect to and
authenticate with the SDP controller. 3.
- A. Initiating hosts are then onboarded and authenticated by the SDP
gateway - B. Finally, SDP controllers are then brought online
- C. SDP gateway is brought online
- D. Clients on the initiating hosts are then onboarded and
authenticated by the SDP controller
Answer: A
Explanation:
Explanation
The third step in the SDP onboarding process is to onboard and authenticate the initiating hosts, which are the clients that request access to the protected resources. The initiating hosts connect to and authenticate with the SDP gateway, which acts as an accepting host and a proxy for the protected resources. The SDP gateway verifies the identity and posture of the initiating hosts and grants them access to the resources based on the policies defined by the SDP controller.

NEW QUESTION # 34
What is one benefit of the protect surface in a ZTA for an
organization implementing controls?
- A. Controls can be moved closer to the asset and minimize risk.
- B. Controls can be implemented at the perimeter of the network and
minimize risk. - C. Controls can be implemented at all ingress and egress points of the
network and minimize risk. - D. Controls can be moved away from the asset and minimize risk.
Answer: A
Explanation:
Explanation
The protect surface in a ZTA is the collection of sensitive data, assets, applications, and services (DAAS) that require protection from threats1. One benefit of the protect surface in a ZTA for an organization implementing controls is that it allows the controls to be moved closer to the asset and minimize risk. This means that instead of relying on a single perimeter or boundary to protect the entire network, ZTA enables granular and dynamic controlsthat are applied at or near the DAAS components, based on the principle of least privilege2. This reduces the attack surface and the potential impact of a breach, as well as improves the visibility and agility of the security posture3.

NEW QUESTION # 35
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) Authentication (2) Authorization of all networked assets
- C. (1) Never trusting (2) Reducing the attack surface
- D. (1) Discovery (2) Mapping access controls and network 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 # 36
In SaaS and PaaS, which access control method will ZT help define
for access to the features within a service?
- A. Role-based access control (RBAC)
- B. Attribute-based access control (ABAC)
- C. Data-based access control (DBAC)
- D. Privilege-based access control (PBAC)
Answer: B
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 # 39
SDP features, like multi-factor authentication (MFA), mutual
transport layer security (mTLS), and device fingerprinting, protect
against
- A. domain name system (DNS) poisoning
- B. code injections
- C. certificate forgery
- D. phishing
Answer: D
Explanation:
Explanation
SDP features, like multi-factor authentication (MFA), mutual transport layer security (mTLS), and device fingerprinting, protect against phishing attacks by verifying the identity and authenticity of both the user and the device before granting access to a resource. Phishing attacks are attempts to trick users into revealing their credentials or other sensitive information by impersonating a legitimate entity or service1. SDP features can prevent phishing attacks by:
MFA: MFA is a security mechanism that requires a user to provide more than one piece of evidence to prove their identity, such as a password, a one-time code, a biometric factor, or a physical token2. MFA can protect against phishing attacks by making it harder for attackers to access a resource even if they manage to obtain the user's password or other credentials2.
mTLS: mTLS is a security protocol that enables mutual authentication and encryption between two parties, such as a client and a server3. mTLS can protect against phishing attacks by ensuring that both the client and the server have valid and trusted certificates, and by preventing attackers from intercepting or modifying the communication between them3.
Device fingerprinting: Device fingerprinting is a technique that identifies and verifies a device based on its unique characteristics, such as its operating system, browser, IP address, or hardware configuration4. Device fingerprinting can protect against phishing attacks by allowing only authorized devices to access a resource, and by detecting any anomalies or changes in the device's attributes that may indicate a compromise4.

- A. Server administrators
- B. ZT administrators
- C. Policy administrators
- D. System administrators
Answer: C
Explanation:
Explanation
In a continual improvement model, policy administrators are the ones who maintain the ZT policies. Policy administrators are ZTA policy entities that are responsible for crafting and maintaining the policies that govern the access to resources in a ZT environment1. Policy administrators define the rules and conditions that specify who, what, when, where, and how an entity can access a resource, based on the principle of least privilege2. Policy administrators also update and review the policies periodically to ensure they are aligned with the changing business and security requirements3.

NEW QUESTION # 42
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 should primarily educate users about secure practices
and promote strong authentication for services accessed via mobile
devices to prevent data compromise. - C. 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. - 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: C
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.

Explanation:
Explanation
Log collection is an essential component of ZTA, as it provides the data needed to monitor, audit, and improve the security posture of the network. By collecting logs from different sources, such as devices, applications, firewalls, gateways, and policies, ZTA can support various functions, such as:
Change management: Logs can help track and document any changes made to the network configuration, policies, or resources, and assess their impact on the security and performance of the network. Logs can also help identify and revert any unauthorized or erroneous changes that may compromise the network integrity1.
Incident management: Logs can help detect and respond to any security incidents, such as breaches, attacks, or anomalies, that may occur in the network. Logs can provide the evidence and context needed to investigate the root cause, scope, and impact of the incident, and to take appropriate remediation actions2.
Visibility and analytics: Logs can help provide a comprehensive and granular view of the network activity, performance, and behavior. Logs can be used to generate dashboards, reports, and alerts that can help measure and improve the network security and efficiency. Logs can also be used to apply advanced analytics techniques, such as machine learning, to identify patterns, trends, and insights that can help optimize the network operations and security3.
