StackWise Questions 2
Question 1
Explanation
A higher priority value for a stack member increases its likelihood to be elected stack master and to retain its stack member number. The priority value can be 1 to 15. The default priority value is 1.
Question 2
Explanation
VSLs can be configured with up to eight links between the two switches across any combination of line cards or supervisor ports to provide a high level of redundancy. If for some rare reason all Virtual Switching Link (VSL) connections are lost between the virtual switch members leaving both the virtual switch members up, the VSS will transition to the dual active recovery mode.
In the dual active recovery mode, all interfaces except the VSL interfaces are in an operationally shut down state in the formerly active virtual switch member. The new active virtual switch continues to forward traffic on all links.
Question 3
Explanation
If for some rare reason all Virtual Switching Link (VSL) connections are lost between the virtual switch members leaving both the virtual switch members up, the VSS will transition to the dual active recovery mode.
In the dual active recovery mode, all interfaces except the VSL interfaces are in an operationally shut down state in the formerly active virtual switch member. The new active virtual switch continues to forward traffic on all links.
Question 4
Explanation
VSS increases operational efficiency by simplifying the network, reducing switch management overhead by at least 50 percent. This includes removing the need for Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP), and Gateway Load Balancing Protocol (GLBP) -> D is correct.
Question 5
Question 6
Explanation
When you add a switch to a stack, the stack master automatically changes the configuration of the new switch. The master switch revises the new member switch port numbers to conform to the current port numbering sequence in the stack. Any existing port-level configuration in the newly-added switch is automatically cleared or updated.

Question 10
Explanation
What are the benefits of VSS?
+ Single point of management, IP address, and routing instance for the Cisco Catalyst 6500 virtual switch
+ Multichassis EtherChannel (MEC) is a Layer 2 multipathing technology that creates simplified loop-free topologies, eliminating the dependency on Spanning Tree Protocol, which can still be activated to protect strictly against any user misconfiguration.
+ Flexible deployment options. The underlying physical switches do not have to be colocated. The two physical switches are connected with standard 10 Gigabit Ethernet interfaces and as such can be located any distance based on the distance limitation of the chosen 10 Gigabit Ethernet optics. For example, with X2-10GB-ER 10 Gigabit Ethernet optics, the switches can be located up to 40 km apart.
Question 11
Question 12
Explanation
Mixed stacks are not supported with switches running the LAN base feature set -> C is not correct.
Switch stacks running the LAN base feature set do not support Layer 3 features -> E is not correct.
Note: Homogeneous stack: A Catalyst 3750-E-only stack with only Catalyst 3750-E switches as stack members or a Catalyst 3750-X-only stack with only Catalyst 3750-X switches as stack members.
One of the switches controls the operation of the stack and is called the stack master. The stack master and the other switches in the stack are all stack members -> D is not correct.
