質問 # 17
Which of the following actions can be included in a conditional "block" policy? (Select 2)
正解：C、D
解説：
The correct answers are A and B . In Zero Trust architecture, policy enforcement is not limited to a plain deny decision. Instead, policy can apply contextual control actions based on the assessed risk of the user, device, session, or application behavior. A conditional block policy is meant to stop or contain malicious or unauthorized activity while also reducing attacker effectiveness.
Quarantine fits this model because it stops access and places the session, user, or device into a controlled state for further review or remediation. That aligns with Zero Trust principles of least privilege, continuous assessment, and adaptive response. Deceive also fits because modern Zero Trust protections can misdirect suspicious or malicious activity toward controlled decoy resources, limiting real exposure while improving detection and response. This is consistent with Zscaler architecture language describing inline prevention, deception, and threat isolation as protective controls.
By contrast, Allow the connection is not a block action, and Firehose is not a standard Zero Trust conditional block control in the architecture concepts you are testing against. Therefore, the two correct answers are Quarantine and Deceive.
質問 # 18
What is the cause of performance issues for some VPN connections?
正解：B
解説：
The correct answer is C . A common cause of poor performance in legacy VPN architectures is hairpinning traffic through a central data center before it can reach cloud or internet destinations. This creates unnecessary distance, added latency, and congestion because the user's traffic does not take the most direct path to the application. Instead, it is first forced back into the enterprise network, often through a VPN concentrator and a stack of centralized security appliances.
This design made more sense when applications mostly lived in corporate data centers. But once applications moved to the cloud and users became more distributed, the same architecture began creating serious user- experience problems. Zero Trust addresses this by allowing access to be enforced closer to the user and closer to the destination, rather than depending on centralized backhaul.
The other options are weaker answers. Split tunneling introduces visibility and control concerns, but it is not the main performance problem being tested here. Vendor throttling and IPSec version mismatch are not the common architectural cause. Therefore, the best answer is hairpinning cloud application traffic through a data center bottleneck .
質問 # 19
Historically, initiators and destinations have shared which of the following?
正解：B
解説：
The correct answer is A . Historically, before modern Zero Trust models were adopted, the normal way to connect a user to an application or service was to place both within a shared network context . This did not always require the exact same subnet, but it did require some level of common routable network connectivity.
Legacy architectures assumed that once the user was on the trusted network, or extended into it through technologies such as VPN, they could reach the destination across that network.
Zero Trust architecture changes this assumption. Zscaler's architectural guidance emphasizes that users should gain access to applications without sharing network context or routing domain with those applications. That is one of the most important distinctions between legacy network-centric security and Zero Trust. The user no longer needs broad network reachability just to get to a specific service. Option B is too narrow because shared access historically did not always mean the same subnet. Options C and D are clearly incorrect. Therefore, the best answer is that initiators and destinations historically shared a network , because legacy connectivity depended on routed network access rather than identity-based, per-application brokerage.
質問 # 20
What are two categories of destination applications in Zero Trust?
正解：C
解説：
The correct answer is A . In Zero Trust architecture, destination applications must be understood and differentiated so the right policy can be applied. Zscaler's ZPA segmentation guidance explains that organizations need to identify, define, and characterize applications as part of moving from network-based access to granular user-to-application segmentation. This naturally supports a distinction between known applications , which are already categorized and understood, and unknown applications , which still require profiling, learning, and more cautious control.
This approach is consistent with Zero Trust because applications are not all treated equally. If an application is well understood, policy can be more precise. If it is unknown or not yet properly categorized, the enterprise may need to inspect, limit, isolate, or otherwise conditionally control access until its risk and purpose are clear. The other options are too narrow or too generic to represent the intended Zero Trust categorization model. Therefore, the best answer is the distinction between known and unknown destination applications, with unknown applications requiring profiling and conditional control before they can be fully trusted.
質問 # 21
What is the trend that is increasing security risk through legacy solutions that drive network sprawl?
正解：C
解説：
The correct answer is D . Zscaler's Zero Trust architecture specifically contrasts modern distributed environments with legacy VPN- and firewall-based designs. The reference architecture explains that users are now remote, applications can be hosted in public cloud, private cloud, or data centers, and access must work across any location. In legacy models, organizations respond by extending IP connectivity outward through VPNs, firewalls, and other network-based controls. That expansion increases the attack surface, preserves broad network trust, and drives network sprawl instead of reducing it.
The same guidance states that Zero Trust gives users access to applications without ever placing them on the network or exposing apps to the internet . This is important because legacy architectures extended the organizational perimeter to end users, allowing lateral movement and increasing risk when users and apps became more distributed. Option A describes a symptom of legacy complexity, but option D captures the broader trend that is causing the sprawl in the first place: cloud migration, remote users, and the continued use of VPN and firewall architectures to maintain connectivity. That is the most accurate Zero Trust answer.
