StackWise Questions 3

November 17th, 2019 Go to comments

Question 1

Question 2

Explanation

Although answer B is a bit unclear but we understand the word “independently” here “can still operate when others go down” so we believe it is correct.

Answer D may be a correct answer but Cisco only mentioned about “proprietary stacking cables”, not “proprietary modules” so we still believe answer B is the better choice.

Question 3

Explanation

The Switch Stack configuration files record these settings:
+ System-level (global) configuration settings – such as IP, STP, VLAN, and SNMP settings – that apply to all stack members
+ Stack member interface-specific configuration settings, which are specific for each stack member

Question 4

Question 5

Explanation

A stack master retains its role unless one of these events occurs:
+ The switch stack is reset.*
+ The stack master is removed from the switch stack.
+ The stack master is reset or powered off -> A is correct.
+ The stack master fails.
+ The switch stack membership is increased by adding powered-on standalone switches or switch stacks.*

In the events marked by an asterisk (*), the current stack master might be reelected based on the listed factors.
When you power on or reset an entire switch stack, some stack members might not participate in the stack master election. Stack members that are powered on within the same 20-second time frame participate in the stack master election and have a chance to become the stack master -> E is correct.

Question 6

Note: The Cisco Virtual Switching System is a clustering technology that pools two Cisco Catalyst 4500-E Series Switches with Cisco Catalyst Supervisor Engine 7-E or 7-LE or two Catalyst 4500-X Series Switches into a single virtual switch.

    Question 2

    Which two statements about stack is true? (Choose two)
    A. It is using one IP address to manage all switches.
    B. It shares one IP address in all switches, but they all work independently.
    C. It is using some IP address to manage all switches.
    D. It uses proprietary modules.

    Answer: A D

    B I do not think is correct because it does not SHARE the IP with the stack, it just has one IP for the stack
    D I think is correct because Stackwise is cisco propriety based on

    Q:6 is confusing as well ?

    what is correct answer upstream or downstream

    Please help?

  4. Q5

    i found it: The new priority value takes effect immediately but does not affect the current stack master. The new priority value helps determine which stack member is elected as the new stack master when the current stack master or the switch stack resets

    So, i things that correct answer are A and E.

    Q5

    May be I need coffee or something but doesn’t the below implies answer C is also correct “When a switch with a higher priority is added to the stack.” ? Or am I missing something ?

    A stack master retains its role unless one of these events occurs:

    + The switch stack membership is increased by adding powered-on standalone switches or switch stacks.*
    In the events marked by an asterisk (*), the current stack master might be reelected based on the listed factors
