質問 # 15
How does integrating DNS Security with ZTNA improve threat detection?
- A. Allows per-query DLP scanning
- B. Replaces TIS risk scoring
- C. Blocks command-and-control domains before application handshake occurs
- D. Eliminates the need for Cloud SWG inspection entirely
正解：C
解説：
DNS Security stops malicious domains early in the flow.
質問 # 16
When integrating ZTNA with Cloud DLP, why should sensitive-data policies be enforced at the application layer rather than the Site layer?
- A. Reduces Connector CPU utilization
- B. Enables granular data handling per application context
- C. Ensures RBAC inheritance across Collections
- D. Avoids duplicate log entries in SIEM
正解：B
解説：
Application-level enforcement applies the most precise control to data transactions.
質問 # 17
Which step ensures that fallback routing does not bypass ZTNA controls?
- A. Lock client DNS to the Connector or SWG addresses
- B. Enable DNSSEC validation on end-user devices
- C. Advertise a default route from the Connector to core routers
- D. Disable local proxy PAC files
正解：A
解説：
Controlling DNS keeps traffic in the ZTNA path.
質問 # 18
Which behavior is specific to agent-less access when the target application uses mutual TLS authentication?
- A. Mutual TLS is unsupported; the session downgrades to plaintext
- B. IDP injects X-509 into the SAML assertion
- C. Endpoint must install a browser plugin to handle client certs
- D. Connector presents a hosted client certificate on behalf of the user
正解：D
解説：
The Connector proxies client certificates for browser-only agent-less sessions.
質問 # 19
What advantage does Health-Check Web-hooks offer over traditional email alerts?
- A. Allows alerts to bypass SIEM parsing
- B. Enables programmatic remediation workflows in SOAR tools
- C. Avoids TLS overhead in outbound notifications
- D. Encrypts notifications with Connector secrets
正解：B
解説：
Web-hooks feed incident data directly into automation pipelines.
質問 # 20
Finally, what is the primary objective of Symantec ZTNA within the broader SASE framework?
- A. Serve as on-prem firewall management console
- B. Replace email security gateways
- C. Grant application-level access based on continuous, context-aware evaluation
- D. Provide global MPLS replacement
正解：C
解説：
ZTNA delivers granular, adaptive access-the core of Zero-Trust within SASE.
質問 # 21
Which benefits of Symantec's SASE solution directly address the shortcomings of traditional perimeter firewalls?
- A. Identity-centric access decisions
- B. Inline CASB shadow-IT discovery
- C. Cloud-native scalability without back-haul
- D. Route-based IPsec mesh tunneling
正解：A、C
解説：
SASE shifts to identity-driven, cloud-native enforcement; CASB discovery is part of SWG, and IPsec meshes belong to legacy SD-WAN, not core SASE.
質問 # 22
A Cloud DLP fingerprint is updated.
What immediate ZTNA action is required?
- A. No action-DLP updates propagate automatically to connected Sites
- B. Restart all Connectors to reload fingerprints
- C. Clear policy staging cache
- D. Re-publish all access policies
正解：A
解説：
Cloud service automatically syncs fingerprints.
質問 # 23
Which two factors impact Connector placement strategy for hybrid cloud workloads?
- A. Latency between Connector and application servers
- B. Regulatory data-residency requirements
- C. Cost per gigabyte of SIEM ingestion
- D. Proximity of IDP to the Connector
正解：A、B
解説：
Latency and residency rules dictate Connector location; IDP proximity and SIEM cost are secondary.
質問 # 24
Which pair of Admin-Portal widgets assists most in day-one validation that traffic is traversing the Connectors?
- A. Policy Staging Summary and Audit Trail
- B. Real-Time Sessions and Connector Health
- C. Application List and User Inventory
- D. DLP Incidents and Risk Analytics
正解：B
解説：
Live session counters alongside health confirm actual routing.
質問 # 25
In an environment requiring strict geo-fencing, what combination of features ensures users outside approved regions are blocked at authentication time?
- A. IDP conditional access rules + ZTNA contextual policy
- B. Disabling token refresh for roaming devices
- C. Connector ACLs based on IP subnets
- D. DNS filtering only
正解：A
解説：
IDP conditions gate authentication, and ZTNA contextual policy enforces at app access.
質問 # 26
A delegated admin must be able to create Policies but not modify Authentication settings.
Which RBAC design satisfies the requirement?
- A. Assign "Policy Admin" role to a specific Collection
- B. Grant "Site Manager" privileges plus SIEM read access
- C. Assign "Policy Admin" role at Tenant level
- D. Clone the "Tenant Admin" role and disable Authentication edit rights
正解：A
解説：
Collection-scoped Policy Admin confines privileges to policy tasks without exposing global authentication.
質問 # 27
During a quarterly review, auditors request proof that deleted Policies cannot be recovered by malicious actors.
Which feature satisfies this control?
- A. Forcing password resets for all admins
- B. Disabling SIEM log export during deletion
- C. Immutable Admin Audit Trail with deletion hashes
- D. Rotating shared secrets for Connectors
正解：C
解説：
The immutable trail records and secures evidence of policy deletions.
質問 # 28
Which Admin-Portal role can read logs and view DLP incidents but cannot edit Policies?
- A. Site Manager
- B. Policy Admin
- C. Tenant Admin
- D. Security Analyst
正解：D
解説：
Security Analyst is a read-only operational role.
質問 # 29
A Zero-Trust rollout mandates step-wise onboarding to avoid productivity loss.
Which Portal feature supports this?
- A. Bulk CSV importer for all Policy objects
- B. Global kill-switch that blocks traffic instantly
- C. Plan -> Onboard wizard that stages Sites, Apps, Policies sequentially
- D. Log replay simulator for historical policies
正解：C
解説：
The wizard guides phased deployment.
質問 # 30
Which two metrics should be monitored to prove value after migrating from VPN to ZTNA?
- A. Growth in number of Sites configured
- B. Decrease in authentication failures
- C. Increase in raw bandwidth usage
- D. Reduction in lateral movement attempts detected
正解：B、D
解説：
Security posture and user success indicate ZTNA effectiveness.
