Exam Questions, Answers,
Today cleared, I prepar
it from www.examcheets.com I had no probs in my test.
A network designer is concerned with the classification
of traffic on a Contivity system. The Contivity device
has one private interface and one public and both
MF Classifier enabled. On Private interface, the Ingress
MF Classifier rule marks all packets to be EF, and
the Egress MF Classifier rule marks all packets to
be AF4. The Ingress MF Classifier does not have a
rule defined. What is the classification of the packets
when they pass thru private to public?
"Legacy Forwarding Priority" has been selected
for Egress queuing mode for a LAN. Under the condition
of heavy traffic. What is the approximate rate per
pass that the packets would be transmitted based on
A. Priority- 1@70%; Priority-2@20%; Priority- 3@8%;
B. Priority- 1@75%; Priority-2@15%; Priority- 3@7%;
C. Priority-1@50%; Priority-2@25%; Priority- 3@5%;
D. Priority-1@60%; Priority-2@25%; Priority- 3@10%;
A remote user transfers files between his client PC
and ftp server in the branch office over Contivity
VPN. The Contivity switch has all its private and
public interfaces shaping enabled. Private interface
shaping rate =1Mbps, and speed? (To simplify the scenario,
assume no bottleneck in Internet cloud.)
A. download = 8Mbps, upload = 4mbps
B. download = 2Mbps, upload = 2mbps
C. download = 4Mbps, upload = 8mbps
D. download = 2Mbps, upload = 4mbps
QoS interface statistics show a public interface has
total available bandwidth of Mbps, used bandwidth
= 9Mbps, and has 3 active users from the same group.
An administrator reconfigured the group to lower the
committed rate from 3Mbps to 2Mbps and enabled admission
control. Based on the scenario, which statement is
A. The 3 active users remain active and the fourth
user is admitted.
B. The switch keeps the 3 active users, but adjust
each committed rate=2Mbps.
C. The 3 active users are logged off by the switch
in order to active the new setting.
D. The fourth user is rejeed, the 3 active users remain
active and rate unchanged.
An operator checks a Contivity Interface QoS Statistic
for a public interface. It shows that BWM is enabled,
and Admission control is enabled, and the number of
and width Total? If a Branch Office tries to get connected,
what will happen?
A. The BO session is rejected, and error message shows
bandwidth is full?
B. The BO session is setup, and lower priority users
are logged off for yielding to higher priority BO.
C. The BO session is setup, but gets 0 bps runtime
bandwidth and the session state is pending? And will
be fully admitted when bandwidth is available.
D. The BO session is partially admitted and gets 50%
of requested bandwidth from over-scribed rate, and
will be fully admitted when bandwidth is available.
Assuming a Contivity supports a maximum of 2000 sessions,
the possible maximum number of connections available
for each Call Admission priority is:
A. Priority-1, 500; Priority-250; Priority-3 200;
B. Priority-1, 600; Priority-2 350; Priority-3 150;
C. Priority-1, 1000; Priority-2800; Priority-3 600;
A. Priority-1, 2000; Priority-2, 1800; Priority-3
1500; priority-4, 1000
A CES serial WAN interface has a date rate of 2Mbps
and is configured with 90% of tunnel traffic rating,
and an over-subscription ratio of 4:1. Both bandwidth
management and admission control are enabled. What
is the maximum number of subscribers with a committed
rate of 64000 bps and an excess rate =128000 bps?
A service provider needs to provide managed VPN service
to an automobile manufacturing company. This customer
has seven regional offices and around 1,000 sales
offices. The seven regional offices range from DSL
to modem Dialup connections. Which routing protocol
will provide the best solution for this network scenario?
A. Static Routing over BO tunnels
B. Dynamic Routing (OSPF) of BO tunnels
C. Static Routing with static failover for the 7 regional
D. OSPF for 7 regional offices and static routing
with static failover for the branch office
A customer is experiencing performance problem on
the Contivity router. They are having OSPF routing
issues running a recent software release. Which scaling
consideration should initially be considered to resolve
A. Implement route policies
B. Downgrade to a software release
C. Upgrade to a higher software release
D. Calculate the overall memory requirement for the

their OSPF network. Their network consists of the
1. Peer-to-peer connections
2. 150 OSPF Tunnels

The design engineer suspects that scaling factors
have been exceeded. If the design engineer's assumption
