the account was locked?A. Run the Failed Logon Report.B. Run the Locked Account Report.C. Run the Voice-mail Accounts Report.D. Run the Active Directory Users and Computers (ADUC) Locked Account Report.E. This can only be done in Active Directory Users and Computers (ADUC).
Anss: A


Q30
You are a Cisco Unity system administrator at CertKing . A CertKing subscriber
complains that Cisco Unity has new messages but the message waiting light does not
light up.
How would you determine what Cisco Unity has been doing for that subscriber?A. Run the Subscriber MWI Detail Report.B. Run the Subscriber Message Activity Report.C. Run the Subscriber Messaging Profile Report.D. Run the Subscriber MTI Status Activity Report.
Anss: B


Q31
You are a Cisco Unity system administrator at CertKing . CertKing had installed the
Cisco Unity system a week ago. You want to review information specific to each
CertKing subscriber, including the exchange alias subscriber extension and the size of
the inbox for each subscriber.
What should you do?A. Run the Usage report.B. Run the Subscriber report.C. Run the Exchange Alias and Storage report.D. None of the above.Ans: B

Q10
You are a technician at CertKing . Your newly appointed CertKing trainee wants to know what the
differences between half-duplex Ethernet and full-duplex Ethernet are.
What should you tell her? (Choose all that apply.)A. Half-duplex Ethernet operates in a shared collision domain.B. Full-duplex Ethernet has a lower effective throughput.C. Half-duplex Ethernet operates in a private collision domain.D. Full-duplex Ethernet allows two-way communication.E. Half-duplex Ethernet operates in a private broadcast domain.Ans: A, D

Explanation:
The original Ethernet specifications used a shared bus, over which only one frame could be sent at any point in
time. So, a single device could not be sending a frame and receiving a frame at the same time because it would
mean that a collision was occurring. Half duplex stations use CSMA/CD to prevent collisions on the network,
because the collision domain is shared. Full duplex Ethernet eliminated the need to collision detection, by
allowing for two way communication.
Incorrect Anss:B. Full duplex effectively doubles the throughput of half-duplex operation, because data can be both sent and
received at the full 10/100 speed.
C, E. In half duplex operation, the network is shared between all devices in the collision domain.


Q11
In data encapsulation, which of the following is the correct order of protocol data units?A. Data, Frame, Packet, Segment, BitB. Data, Frame, Segment, Packet, BitC. Data, Packet, Frame, Segment, BitD. Data, Packet, Segment, Frame, BitE. Data, Segment, Frame, Packet, BitF. Data, Segment, Packet, Frame, BitAns: F

Explanation:
Data Encapsulation
Step 1 Create the application data and headers
o Data
Step 2 Package the data for transport
o Segment
Step 3 Add the destination and source network layer addresses to the data
o Packet
Step 4 Add the destination and source data link layer addresses to the data
o Frame
Step 5 Transmit the bits
o Bit

Q12
You are the network administrator at CertKing . CertKing uses the network address 210.10.2.0. You want
to subnet this network with a /28 mask.
How many usable subnetworks and host addresses per subnet will this subnet mask provide?A. 30 networks and 6 hosts.B. 6 networks and 30 hosts.C. 8 networks and 32 hosts.D. 32 networks and 18 hosts.E. 14 networks and 14 hosts.Ans: E
A 28 bit subnet mask (11111111.11111111.11111111.11110000) applied to a class C network uses a 4 bits for
networks, and leaves 4 bits for hosts. Using the 2n-2 formula, we have 24-2 (or 2x2x2x2-2) which gives us 14.
