5. You have been assigned a ticket from your company’s help desk stating that a user is unable to
access their files over the VPN although they can access the same files when connected to the
corporate network at their office.While troubleshooting the problem, you have the user per-
form a traceroute between their workstation and the VPN gateway while connected to the
VPN.The traceroute results show that all eight hops respond with acceptable response times.
What do you suspect the problem is?

A. Network latency.
B. The user is not connected to the VPN.
C. Access permissions for the files are incorrect.
D. The VPN gateway is behaving abnormally and needs to be examined.
B. If the traceroute is showing eight hops between the client and the VPN gateway, the user
could not be connected to the VPN. Remember that a VPN connection once established shows
up as a single hop.
A, C, D.Answer A is incorrect because the traceroute shows acceptable response times for the
connections indicating that latency is not the issue.Answer C is incorrect because the user can
successfully access the file at the office, which indicates that the permissions are correct.Answer
D is incorrect because determining this solution would require much more troubleshooting.
While it is possible that a problem with the gateway is causing the user to be unable to connect
to the VPN, you must first determine that the user is not connected then troubleshoot further
to determine the cause.

6. You are working with a network engineer to diagnose the cause for intermittent communica-
tion issues on the corporate network.The engineer determines that the cause is attenuation on
the UTP cables used for network traffic.What element of STP cable could help with this?
A. Increased twist rate
B. Shielding
C. Higher wire gauge
D. Optical data transmission
B. STP cables contain shielding which can help prevent issues related to attenuation.
Incorrect Answers & Explanations: A, C, D. Answer A is incorrect because although twist rate
can have an effect on attenuation, UTP and STP cable of the same category share the same
twist rate.Answer C is incorrect because the wire gauge is the same for UTP and STP cables of
the same category.Answer D is incorrect because STP cables do not use optical data transmis-
sion.

7. You are working with a team to prepare outdated workstations for resale.As part of this task,
you must ensure that no corporate data remains on the system.What is the best way to do this?
A. Destroy the system hard disk drive.
B. Overwrite the system hard disk drive with random data to clear it.
C. Format the system hard disk drive.
D. Overwrite the system hard disk drive with random data multiple times to clear it
securely.
