A mismatch in OSPF area ID types (e.g., normal vs. stub)

Answer

Incorrect OSPF hello or dead timer intervals

Answer

Authentication type or password mismatch

Question 17

An administrator is troubleshooting a Cortex XDR agent that has stopped reporting to the management console. The local agent service is running, but network traces show TLS handshake failures with the Cortex XDR server. What is the most likely cause?

Accepted Answer

An intervening proxy or firewall is decrypting TLS traffic without the Cortex XDR root certificate installed in the agent trust store.. TLS handshake failures usually stem from expired certificates, SSL inspection proxies intercepting traffic without proper root CA trust, or incorrect proxy settings.

Answer

The endpoint's local time is synchronized with an NTP server outside the local subnet.

Answer

The agent license key has reached its maximum daily log ingestion limit.

Answer

The Cortex XDR agent version is newer than the cloud backend tenant version.

Question 18

An enterprise environment contains legacy Windows servers that cannot support the latest Cortex XDR agent version due to OS limitations. How does Cortex XDR handle protection for these older operating systems?

Accepted Answer

By deploying a compatible legacy agent version that supports older OS APIs while providing core malware and exploit prevention.. Cortex XDR supports legacy operating systems with specific legacy agent versions that provide core prevention capabilities supported by those OS architectures.

Answer

By forcing an automatic in-place upgrade of the legacy Windows server to Windows 11.

Answer

By routing all legacy server traffic through a next-generation firewall proxy instead of installing an agent.

Answer

By disabling all security checks for servers older than five years.

Question 19

An administrator is reviewing security events in Cortex XDR and notices multiple alerts tagged with MITRE ATT&CK techniques. Which THREE benefits does integrating MITRE ATT&CK taxonomy into Cortex XDR provide for analysts? (Choose three)
