StackWise Questions 2

September 5th, 2017 in SWITCH 300-115 Go to comments

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 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.
