1. A BayStack 450-24T switch will be added to an existing stack of two
BayStack 470-24T switches. The software Release running on the BayStack
450-24T switch is compatible with the software Release running on the
BayStack 470-24T switches. To complete the stack creation successfully,
which two configuration changes are necessary? (Choose two.)
A. Set the Unit Select switch on the BayStack 450-24T to the "Off"
position.
B. Set the Unit Select switch on the BayStack 450-24T to "Base" ("On"
position).
C. Set the Stack Mode for all BayStack 470-24T switches to Hybrid and
then reset the stack.
D. Cable the BayStack 450-24T switch into the stack, power off all
units, and then power up the stack.
E. Set the Stack Mode for the Base BayStack 470-24T switch to Hybrid and
leave the other BayStack 470-24T switch as Pure.
Answer: AC
2.You are configuring a BayStack 470-48T switch for QoS and it is
necessary to implement a meter as follows:
Limit bandwidth utilization to 20 Mbps.
Drop all traffic that exceeds the 20 Mbps threshold.
How do you ensure that traffic that exceeds the 20 Mbps threshold is
dropped?
A. When adding the meter to the policy, set Out-of-Profile Action to
Drop_Traffic .
B. When defining the Committed Burst Size of the meter, set Maximum
Burst Size to 0 kbps .
C. When adding the meter to the interface group, set
Threshold-Exceeded-Traffic to Drop .
D. When defining the Committed Burst Size of the meter, set Maximum
Burst Size to 0 kbps and Duration to 0 seconds .
Answer: A
3. Click the exhibit button.
Given the following BayStack 325-24T switch configuration:
VLAN 10 is a port-based VLAN.
Port 1 is an untagged member of VLAN 10.
Port 5 is a tagged member of VLAN 10.
The device on Port 1 transmits an untagged frame to the device on Port
5. How will an untagged frame be treated when it reaches Port 5 on this
switch?
A. It will be discarded when it is received.
B. It will be placed in a hardware-based queue based on Priority 6, it
will be tagged, and transmitted out Port 5 with Priority 2.
C. It will be placed in a hardware-based queue based on Priority 6, it
will be tagged, and transmitted out Port 5 with Priority 6.
D. It will be placed in a hardware-based queue based on Priority 2, it
will be tagged, and transmitted out Port 5 with Priority 2.
Answer: C
4. Given the following information:
A customer has a stack of four BayStack BPS switches configured in pure
mode and functioning properly.
Two BayStack 450-24T switches are added to the stack to increase its
capacity and the BayStack BPS stack operation mode is changed to hybrid.
After rebooting the stack, it appears to be functioning properly but,
all VLAN configurations have been lost.
What is the most likely cause of this issue and which action should you
take to resolve it?
A. A BayStack 450-24T has incorrectly been assigned as the base unit.
Define a BayStack BPS as the base unit and power cycle the stack to
resolve the issue.
B. The Interoperability Software Version Number (ISVN) of the BayStack
450-24T software does NOT match the ISVN of the BayStack BPS software.
Upgrade the BayStack 450-24T software to resolve the issue.
C. A hybrid stack only supports 64 VLANs. If more are defined on a pure
BayStack BPS stack, when you change to hybrid mode you will lose all the
VLANs. A maximum of 64 VLANs can be re-entered to resolve the issue.
D. When changing from a pure to a hybrid stack, the VLAN configuration
will always be lost. Before changing to hybrid mode, the configuration
file must be downloaded to a TFTP server, and then uploaded after
changing to hybrid mode.
Answer: C
5. On a BayStack 470 switch you need to disable Internet Group
Management Protocol (IGMP) snooping for a customer's VLAN (100). Using
the Console Interface (CI) Menus, how should you accomplish this task?
A. From the VLAN configuration screen disable IGMP proxy for VLAN 100.
B. From the VLAN configuration screen disable IGMP snooping for VLAN
100.
C. From the VLAN configuration screen, configure the VLAN setup of port
100.
D. From the Switch configuration screen choose IGMP configuration and
disable IGMP snooping for VLAN 100.
Answer: B
6. You have installed a new BayStack 460-24T switch into a customer's
network and are using the QoS Wizard to configure the QoS settings for
various IP traffic flows. Which two IP applications can you directly
choose in the QoS Wizard to prioritize inbound frames based on traffic
type? (Choose two.)
A. E-mail (SMTP)
B. File Transfer (FTP)
C. Multicasting (IGMP)
D. Trivial File Transfer (TFTP)
E. Network Management (SNMP)
Answer: AB
7. What is required to apply traffic shaping to an uplink connection
from a BayStack 470-48T switch to the Passport 8600 using the Web-based
Management System Interface?
A. a Media Dependent Adapter (MDA)
B. NO additional equipment is required
C. a Gigabit Interface Connector (GBIC)
D. a mini Gigabit Interface Connector (GBIC)
Answer: C
8. Given the following information:
A BayStack 460-24T-PWR switch is being installed.
The switch will be fully populated with all devices requiring Power over
Ethernet (PoE).
The switch has been connected to both internal and external power
sources.
The switch will be configured through web-based management.
Once you access the BayStack 460 via the BS460_24T_PWR(config)#poe
poe-dc-source command, which configuration will provide the most power
to supply PoE to the connected devices?
A. nes - Set DC power source from NES
B. rpsu - Set DC power source from the rpsu
C. baystack10 - Set DC power source from BayStack 10
D. unit - Set power pairs of another unit in a stack
Answer: A
