NO.1 Ferris Plastics, Inc. is a medium sized company, with an enterprise network
(access,
distribution and core switches) that provides LAN connectivity from
user PCs to corporate servers.
The distribution switches are configured to
use HSRP to provide a high availability solution.
DSW1 -primary device for
VLAN 101 VLAN 102 and VLAN 105
DSW2 - primary device for VLAN 103 and VLAN
104
A failure of GigabitEthemet1/0/1 on primary device should cause the
primary device to release its
status as the primary device, unless
GigabitEthernet1/0/1 on backup device has also failed.
Troubleshooting has
identified several issues. Currently all interfaces are up. Using the
running
configurations and show commands, you have been asked to investigate
and respond to the
following question.
During routine maintenance, it
became necessary to shut down the GigabitEthernet1/0/1 interface
on DSW1. All
other interfaces were up. During this time, DSW1 remained the active device for
the
VLAN 102 HSRP group. You have determined that there is an issue with the
decrement value in the
track command for the VLAN 102 HSRP group. What needs
to be done to make the group function
properly?
A. The decrement value on
DSW1 should be greaterthan 5 and less than 15. 0
B. The decrement value on
DSW1 should be greaterthan 9 and less than 15.
C. The decrement value on DSW1
should be greaterthan 11 and less than 19.
D. The decrement value on DSWTs
should be greaterthan 190 and less than 200.
E. The decrement value on DSWTs
should be greaterthan 195 and less than 205.
Answer: C
NO.2 Refer to
the exhibit.
Which set of configurations will result in all ports on both
switches successfully bundling into an
EtherChannel?
A. switch1
channel-group 1 mode active switch2 channel-group 1 mode auto
B. switch1
channel-group 1 mode desirable switch2 channel-group 1 mode passive
C.
switch1 channel-group 1 mode on switch2 channel-group 1 mode auto
D. switch1
channel-group 1 mode desirable switch2 channel-group 1 mode auto
Answer:
D
NO.3 Which VLAN range is eligible to be pruned when a network engineer
enables VTP pruning on a
switch?
A. VLANs 1-1001
B. VLANs 1-4094
C.
VLANs 2-1001
D. VLANs 2-4094
Answer: C
NO.4 A network engineer
deployed a switch that operates the LAN base feature set and decides to
use
the SDM VLAN template. The SDM template is causing the CPU of the switch
to
spike during peak working hours. What is the root cause of this
issue?
A. The VLAN receives additional frames from neighboring
switches.
B. The SDM VLAN template causes the MAC address-table to
overflow.
C. The VLAN template disables routing in hardware.
D. The switch
needs to be rebooted before the SDM template takes effect.
Answer:
C
NO.5 What does the command vlan dot1q tag native accomplish when
configured under global
configuration?
A. All frames within the native
VLAN are tagged, except when the native VLAN is set to 1.
B. It allows
control traffic to pass using the non-default VLAN.
C. It removes the 4-byte
dot1q tag from every frame that traverses the trunk interface(s).
D. Control
traffic is tagged.
Answer: D
NO.6 A network engineer must improve
bandwidth and resource utilization on the switches by
stopping the
inefficient flooding of frames on trunk ports where the frames are not needed.
Which
Cisco IOS feature can be used to achieve this task?
A. VTP
pruning
B. access list
C. switchport trunk allowed VLAN
D. VLAN
access-map
Answer: A
NO.7 Refer to the exhibit.
A network engineer
investigates a recent network failure and notices that one of the interfaces
on
the switch is still down. What is causing the line protocol on this
interface to be shown as down?
A. There is a layer 1 physical issue.
B.
There is a speed mismatch on the interface.
C. The interface is configured as
the target of the SPAN session.
D. The interface is configured as the source
of the SPAN session.
E. There is a duplex mismatch on the
interface.
Answer: C
NO.8 A network engineer wants to ensure Layer 2
isolation of customer traffic using a private VLAN.
Which configuration must
be made before the private VLAN is configured?
A. Disable VTP and manually
assign VLANs.
B. Ensure all switches are configured as VTP server mode.
C.
Configure VTP Transparent Mode.
D. Enable VTP version 3.
Answer: C
