B. With four 100Mbps connections defined in a Distributed
C. With six 100Mbps connections defined in a Split MLT
D. With six 100Mbps connections defined in a DMLT.
E. With four 100Mbps connections defined in an SMLT.
Question: 2 Port-based VLAN 10 has been configured on
a standalone BayStack 470-24T switch. Port 5 must now
be added to VLAN 10. What are the steps necessary to
add Port 5 to VLAN 10 in Java Device Manager (JDM)?
A. From the main menu choose Application-> LAN->
VLAN Configuration. In the VLAN Table section, click
the Modify icon for VLAN 10. Now add Port 5 to the list

click on Port Members for VLAN 10, and add Port 5 to
the list of members.
Question: 3 A BayStack 460-24T-PWR switch is being configured
for Quality of Service (QoS), and it is necessary to
implement a meter as follows:
Limit bandwidth utilization to 20Mbps.
Drop all traffic that exceeds the 20Mbps threshold.
How do you ensure that traffic that exceeds the 20Mbps
threshold is dropped?
A. When defining the meter's Committed Burst Size ,set
Maximum Burst Size to 0 kbps
B. When defining the meter's Committed Burst Size set
Maximum Burst Size to 0 kbps , and Duration to 0 seconds
C. When adding the meter to the interface group, set
Threshold-Exceeded-Traffic to Drop
D. When adding the meter to the policy, set Out-of-Profile
Action to Drop_Traffic.
