STP Network Design and Implementation

Question 1

When designing a network with STP, what is the primary reason for creating redundant paths between switches?

Accepted Answer

To ensure high availability and fault tolerance

Answer

To increase network bandwidth

Answer

To enhance network security

Answer

To simplify network management

Question 2

In a network with multiple VLANs, which STP variant should be used to optimize spanning tree performance?

Accepted Answer

Multiple Spanning Tree Protocol (MSTP)

Answer

Common Spanning Tree (CST)

Answer

Rapid Spanning Tree Protocol (RSTP)

Answer

Per-VLAN Spanning Tree (PVST)

Question 3

How does the network topology affect STP operation and design?

Accepted Answer

It influences the election of the Root Bridge and path cost calculations

Answer

It determines the maximum bandwidth available to each switch

Answer

It dictates the encryption methods used for data transmission

Answer

It sets the time intervals for data retransmission

Question 4

What is a key consideration when implementing STP in a network with a mix of older and newer devices?

Accepted Answer

Ensuring all devices support the same version of STP

Answer

Configuring STP to ignore BPDUs from older devices

Answer

Adjusting STP timers to accommodate slower devices

Answer

Using a single STP instance for the entire network

Question 5

How does STP interact with Link Aggregation (e.g., EtherChannel) in a network?

Accepted Answer

STP uses the aggregated link as a single logical link when calculating path costs

Answer

STP disables Link Aggregation to prevent loops

Answer

STP requires separate STP instances for each physical link in the aggregation

Answer

STP does not interact with Link Aggregation, as they operate independently
