A remote user (User1) is unable to reach a newly provisioned corporate windows workstation. The system
administrator has been given the following log files from the VPN, corporate firewall and workstation host.
Which of the following is preventing the remote user from being able to access the workstation?
A.
Network latency is causing remote desktop service request to time out
B.
User1 has been locked out due to too many failed passwords
C.
Lack of network time synchronization is causing authentication mismatches
D.
The workstation has been compromised and is accessing known malware sites
E.
The workstation host firewall is not allowing remote desktop connections
The log says authentication succeeded after three failed attempts and then got disconnected because of a time out. How is this B???
VPN logs:
3 failed attempts followed by a successful attempt. Connection disconnects after an hour due to idle connection.
Corp firewall:
User tries to ping the RDP server, ping is denied. Return RDP traffic is accepted. The pings are irrelevant.
Workstation host firewall:
Outbound RDP to the server is allowed, return RDP traffic is dropped.
Answer should be E.
