8. What is a solution for identifying malware through file analysis performed in a controlled and monitored sandbox environment?

  • Cisco Threat Grid
  • Cisco Umbrella
  • Cisco Stealthwatch
  • Cisco ISE

Explanation: Cisco Threat Grid performs file analysis in a controlled and monitored sandbox environment to observe and analyze the behavior against millions of samples to determine whether a file is malware.

9. Which security function is provided by a firewall?

  • allows or blocks trafic by performing packet filtering and stateful inspection
  • passively monitors network traffic and logs intrusion attacks for security analysis
  • passively monitors network traffic and automatically blocks intrusion attacks
  • aggregates and correlates threat events, contextual information, and network device performance data

Explanation: A firewall monitors incoming and outgoing network traffic and allows or blocks traffic based on filtering and stateful inspection of packets.

10. What is the default timeout period for initiation of 802.1x authentication before the authenticator with MAB enabled proceeds with MAC authentication bypass?

  • 30 seconds
  • 90 seconds
  • 120 seconds
  • 180 seconds

Explanation: The MAB authentication process is initiated by the authenticator by sending an EAPoL identity request message to the endpoint every 30 seconds to determine if it has a supplicant. After three timeouts (90 seconds) the authenticator proceeds to authenticate via MAB.

Explanation: Cisco Web Security Appliance (WSA) is a web gateway that offers a wide range of security protection. It makes use of Cisco AMP and Cisco Talos for real-time intelligence so that it can stay ahead of the evolving threat landscape and protect against the latest exploits.

12. Which place in the network (PIN) typically contains the critical information assets and intellectual property of an organization?

  • data center
  • edge
  • branch
  • WAN

Explanation: Data centers house the servers containing the critical information assets and intellectual property of an organization.

13. Which three threat protection capabilities are provided by Cisco ESA? (Choose three.)

  • spam protection
