Cisco 300-710 Practice Test 76
Question 750
A firewall service owner escalates the following: An investigator wants to isolate a host from a firewall alert and assumes an XDR dashboard action is available without integrated product permissions. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Review dynamic malware dispositions and retrospective updates, linking file hashes, events and affected host context.
- Inspect incident evidence graph, source timestamps, response connector state, action permissions and affected endpoint identity.
- Use supported XDR investigation context and authorized response integrations, validating affected identities and approval before containment.
- Inspect connector health, endpoint GUID, file hash, event timestamps and available trajectory references.
- Assume an XDR correlated incident automatically proves compromise and can command every connected security product regardless of permissions.
Explanation
Correct Answers
B:Direct independent How to verify: Inspect incident evidence graph, source timestamps, response connector state, action permissions and affected endpoint identity.
C:Appropriate implementation: Use supported XDR investigation context and authorized response integrations, validating affected identities and approval before containment. Case details: An investigator wants to isolate a host from a firewall alert and assumes an XDR dashboard action is available without integrated product permissions. Governing behavior: XDR aggregates security signals and may orchestrate supported responses, but integration capabilities and authorization limit available actions.
Incorrect Answers
A:That option would review dynamic malware dispositions and retrospective updates, linking file hashes, events and affected host context, but it addresses a different concern. Governing behavior: XDR aggregates security signals and may orchestrate supported responses, but integration capabilities and authorization limit available actions.
D:This alternative describes a different control, Secure Endpoint integration and file trajectory correlation, rather than this scenario’s Cisco XDR investigation correlation and response: Inspect connector health, endpoint GUID, file hash, event timestamps and available trajectory references.
E:Unsafe or unsupported shortcut for this firewall scenario: Assume an XDR correlated incident automatically proves compromise and can command every connected security product regardless of permissions.
Question 751
An approved maintenance window surfaces this issue: FMC is configured for identity integration but never receives relevant user or session context because pxGrid client registration is incomplete. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.

Question 752
A Secure Firewall deployment change request reports: FMC is configured for identity integration but never receives relevant user or session context because pxGrid client registration is incomplete. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
- pxGrid allows authorized security systems to share context, but certificate trust, topics and lifecycle of identity mappings matter.
- RTC coordinates containment through integrated policy and identity mechanisms; unsafe scoping can turn a security alert into widespread outage.
- File malware inspection must be enabled in the relevant traffic path, and observing a file event is distinct from blocking or quarantining it.
- Assume enabling pxGrid alone means every device IP is always mapped to the correct current identity.
Explanation
Correct Answer
A:Underlying platform principle: pxGrid allows authorized security systems to share context, but certificate trust, topics and lifecycle of identity mappings matter.
