NO.3 A customer is planning a new VoIP network based on their existing PBX and corporate network. They
need historical information about calling patterns in order to plan for VoIP traffic. What is the best source
of this type historical information?
A. Operational Measurements from switch
B. Error messages from all networking devices
C. Alarm indications from all networking devices
D. Log reports from switch and all networking devices

NO.4 Given the following network information: ?A company with a mixed VoIP and data network is
experiencing bad voice quality with VoIP calls during normal business hours. ?Tests within their LAN
segments warn of excessive jitter, delay, and in some cases packet retransmissions. ?There is a pair of
switches that all traffic converges upon. The link between the two switches is a 100/Full Fast Ethernet
connection that is operating at near maximum capacity for the majority of the day. ?At any given time, the
estimated traffic on the link between the two switches is 200 Mbps. Which two configuration changes will
improve the voice quality of the VoIP calls and prevent possible VoIP issues in the future between these
two switches? (Choose two.)
A. Place a router between the two switches and configure the 100 Mbps links to the two switches with a
higher QoS for VoIP traffic.
B. Prioritize the traffic on the switches to give VoIP improved QoS. Prioritize only the traffic on the
switches to give VoIP calls improved QoS.
C. Provide a larger aggregated bandwidth of 300 Mbps by trunking three interfaces together on the two
switches using Multilink Trunks (MLTs).
D. Purchase two new Layer 2 switches that are capable of gigabit Ethernet to replace the Fast Ethernet
connection with a single gigabit Ethernet connection.

NO.5 After assessing a customer's network in preparation for a multi-site LAN/WAN VoIP deployment, you
have determined the following: ?Average 5% dropped packets in end to end tests ?Intermittent voice
muting ?Unacceptable delay The customer wishes to upgrade their network and correct these
deficiencies. Suggest one solution that will give the most noticeable improvement and prepare the
network for future growth with the least complexity.
A. Implement an all optical network.
B. Reduce frame size for all packets.
C. Increase LAN/WAN bandwidth by 30%.
D. Implement QoS technique like DiffServ.

NO.6 Given the following network assessment information: ?At all times of the day there is sufficient
bandwidth between all test points sitting on the LAN drops as well as the remote offices across the WAN
circuits where Internet Telephones will be placed. ?All the call servers, media gateways and signaling
servers are on the same VLAN along with the data network traffic. ?All of the servers are duplicated on
the network to ensure five nines (99.999%) of reliability and call handling. ?There is only one
physical/logical path to each LAN drop and remote office. ?The architecture of the network is in a physical
star topology with all VoIP processing servers at the center of the star, including the duplicate
servers. ?Each of the remote sites were built from the ground up for VoIP and data traffic with NO regard
for any call processing locally. All calls must go back to the campus network. Which three
recommendations should you make to the customer concerning their network to enable it to support VoIP
traffic? (Choose three.)
A. Add data path redundancy to give the network survivability.
B. Ensure that a backup generator sustains the power of all the network equipment.
C. Recommend a re-evaluation to obtain network delay and jitter information to ensure that these
properties are within the appropriate bounds.
D. Segment the call server, media gateway, and signaling server to appropriate VLANs to ensure
signaling traffic is NOT impacted by standard IP data.

NO.7 A customer wants to implement VoIP network in their LAN/WAN environment. Following the network
assessment, you have to make the appropriate recommendations to address network issues that can
cause problems for real-time VoIP traffic. Based on the following, what should be your first
recommendation?
A. Use media shared hubs for LAN connection.
B. Change the CODEC selection for LAN devices only.
C. Put call servers, signaling servers and media gateways on one VLAN.
D. Configure all interfaces to eliminate duplex mismatch and set to auto negotiate.
Answer: D

NO.8 A company wants its network to be configured and if necessary upgraded to enable it to handle the
addition of VoIP traffic along with other IP data. During the network assessment you identify: ?The core of
the network is a high-speed data center where there is ample bandwidth to support the addition of VoIP
traffic. ?The remote offices that the data center services are all connected via Frame Relay (FR). After
setting up several NetIQ Chariot VoIP endpoints at remote - office locations, you identify the following
issues: ?Excessive delays during peak hours, as much as 200 milliseconds on round trips. ?There are
dropped packets even at low usage rates. ?The jitter across the FR links is excessive when it is greater
than 30 milliseconds. Which two changes should occur before the customer's network is declared VoIP -
ready? (Choose two.)
A. Upgrade the data center to Layer 3 switching.
B. Modify the 802.1p values on the VLANs to reduce the dropped packets to the remote sites.
C. Increase the Committed Information Rate (CIR) to guarantee that enough bandwidth is available to the
remote sites.
D. Implement traffic prioritization for shaping and policing on the routers (data center and remote offices)
to ensure that VoIP traffic is prioritized over non-time-sensitive traffic.
