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 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 7

Question 8

Question 9

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.

Reference: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/15-0_1_se/configuration/guide/3750xcg/swstack.pdf

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.

    Where are the questions

    More information on Question 7:

    The election process goes through the following:
    1. The current switch master (obviously). If not set, then:
    2. The priority set on the switch itself (config)#switch X priority Y). If a match, then:
    3. A pre-configured switch over a non-preconfigured switch. If a match, then:
    4. The highest/best feature set. If a match, then:
    5. The switch with the highest uptime. If a match, then:
    6. The switch with the lowest MAC address.

    q5 If the stack master detects that the software on a new switch does not match, it upgrades (or downgrades) the new switch with the active image that is running on the switch stack by using the automatic upgrade (auto-upgrade) and the automatic advise (auto-advise) features.

    For qn10, why C is not the answer?

    Q. What are the benefits of VSS?

    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.
