Question #14

Refer to Exhibit:

With Access-1, What needs to be identically configured With MSTP to load-balance VLANS?

A . Spanning-tree bpdu-guard setting
B . Spanning-tree instance vlan mapppjng
C . spanning-tree Cist mapping
D . Spanning-tree root-guard setting

Correct Answer: B
B

Explanation:

The correct answer is B. Spanning-tree instance VLAN mapping.

To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.

According to the Cisco document Understand the Multiple Spanning Tree Protocol (802.1s), one of the steps to configure MST is:

Split your set of VLANs into more instances and configure different MST settings for each of these instances. In order to easily achieve this, elect Bridge D1 to be the root for VLANs 501 through 1000, and Bridge D2 to be the root for VLANs 1 through 500.

These statements are true for this configuration:

Switch D1(config)#spanning-tree mst configuration

Switch D1(config-mst)#instance 1 vlan 501-1000

Switch D1(config-mst)#exit

Switch D1(config)#spanning-tree mst 1 priority 0

Switch D2(config)#spanning-tree mst configuration

Switch D2(config-mst)#instance 2 vlan 1-500

Switch D2(config-mst)#exit

Switch D2(config)#spanning-tree mst 2 priority 0

The above commands create two MST instances, 1 and 2, and map VLANs 501-1000 to instance 1 and VLANs 1-500 to instance 2. Then, they make switch D1 the root for instance 1 and switch D2 the root for instance 2.

The other options are incorrect because:

A) Spanning-tree bpdu-guard setting is a security feature that disables a port if it receives a BPDU from an unauthorized device. It does not affect load balancing with MSTP.

C) Spanning-tree CIST mapping is not a valid command. CIST stands for Common and Internal Spanning Tree, which is the spanning tree instance that runs within an MST region and interacts with other regions or non-MST switches.

D) Spanning-tree root-guard setting is another security feature that prevents a port from becoming a root port if it receives superior BPDUs from another switch. It does not affect load balancing with MSTP.

Question #16

Describe the difference between Class of Service (CoS) and Differentiated Services Code Point (DSCP).

A . CoS has much finer granularity than DSCP
B . CoS is only contained in VLAN Tag fields DSCP is in the IP Header and preserved throughout the IP packet flow
C . They are similar and can be used interchangeably.
D . CoS is only used to determine CLASS of traffic DSCP is only used to differentiate between different Classes.

Question #18

A customer just upgraded aggregation layer switches and noticed traffic dropping for 120 seconds after the aggregation layer came online again.

What is the best way to avoid having this traffic dropped given the topology below?

A . Configure the linkup delay timer to 240 seconds to double the amount of lime for the initial phase to sync
B . Configure the linkup delay timer to exclude LAGS 101 and 102, which will allow time for routing adjacencies to form and to learn upstream routes
C . Configure the linkup delay timer to include LAGs 101 and 102, which will allow time for routing adjacencies lo form and to learn upstream routes
D . Configure the linkup delay timer to 120 seconds, which will allow the right amount of time for the initial phase to sync
