A network engineer wants to analyze all incoming and outgoing packets for an interface that is connected to an access switch. Which three items must be configured to mirror traffic to a packet sniffer that is connected to the distribution switch? (Choose three.)
A.      A monitor session on the distribution switch with a physical interface as the source and remote SPAN VLAN as the destination.
B.     A remote SPAN VLAN on the distribution and access layer switch.
C.      A monitor session on the access witch with a physical interface source and the remote SPAN VLAN as the destination.
D.     A monitor session on the distribution switch with a remote SPAN VLAN as the source and physical interface as the destination.
E.      A monitor session on the access switch with a remote SPAN VLAN source and the physical interface as the destination.
F.       A monitor session on the distribution switch with a physical interface as the source and a physical as the destination

How can the traffic that is mirrored out the Gigabitether0/48 port be limited to only traffic that is  received or transmitted in VLAN 10 on the GigabitEthernet0/1 port?
Interface GigabitEthernet0/1
     switchport
     switchport mode trunk
     switchport trunk allowed vlan 1-100
     !
Interface GigabitEthernet0/48
     switchport
     switchport mode access
     !
monitor session 1 source interface GigabitEthernet0/1
monitor session 1 destination interface GigabitEthernet0/48
A.      Change the configuration for GigabitEthernet0/48 so that it is a member of VLAN 10.
B.      Add an access-list to GigabitEthernet0/48 to filter out traffic that is not in VLAN 10.
C.      Apply the monitor session filter globally to allow only traffic from VLAN 10.
D.      Change the monitor session source VLAN 10 instead of the physical interface.

What percentage of bandwidth is reduced when a stack cable is broken?
A.0
B.25
C.50
D.75
E.100
Explanation: Physical Sequential Linkage
The switches are physically connected sequentially, as shown in figure 3. A break in any one of the cables will result in the stack bandwidth being reduced to half of its full capacity. Subsecond timing mechanisms detect traffic problems and immediately institute failover. This mechanism restores dual path flow when the timing mechanisms detect renewed activity on the cable.

       A.4
       B.5
       C.8
       D.9
       E.10
       F.13
Explanation: Up to 9 Cisco Catalyst switches can be stacked together to build single logical StackWise switch since Cisco IOS XE Release 3.3.OSE. Prior to Cisco IOS XE Release3.3.OSE, up to 4 Cisco Catalyst switches could be stacked together.
