Which of the following specifications is a companion to the IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) algorithm, and warrants the use multiple spanning-trees? ()
A. IEEE 802.1s (MST)
B. IEEE 802.1Q (CST)
C. Cisco PVST+
D. IEEE 802.1d (STP)
E. None of the other alternatives apply
pany uses MSTP within their switched LAN.
What is the main purpose of Multiple Instance Spanning Tree Protocol (MSTP)?()
A. To enhance Spanning Tree troubleshooting on multilayer switches
B. To reduce the total number of spanning tree instances necessary for a particular topology
C. To provide faster convergence when topology changes occur in a switched network
D. To provide protection for STP when a link is unidirectional and BPDUs are being sent but not received
E. None of the other alternatives apply
The Company network utilizes the Multiple-instance Spanning Tree protocol in its switched LAN.
Which three statements about the MST protocol (IEEE 802.1S) are true? ()
A. To verify the MST configuration, the show pending command can be used in MST configuration mode.
B. When RSTP and MSTP are configured; UplinkFast and BackboneFast must also be enabled.
C. All switches in the same MST region must have the same VLAN-to-instance mapping, but different configuration revision numbers.
D. All switches in an MST region, except distribution layer switches, should have their priority lowered from the default value 32768.
E. An MST region is a group of MST switches that appear as a single virtual bridge to adjacent CST and MST regions.
F. Enabling MST with the "spanning-tree modemst" global configuration command also enables RSTP.
On switch R1 you issue the "udld enable" global command.
What does this command accomplish? ()
A. Enables all fiber-optic LAN ports for Unidirectional LINK Detection (UDLD)
B. Enables all copper media LAN ports Unidirectional Link Detection (UDLD)
C. Overrides the default UDLS setting for all ports
D. Globally enables all ports on the device for Unidirectional Link Detection (UDLS)
E. None of the other alternatives apply
Switch R1 has been configured with the root guard feature.
What statement is true if the spanning tree enhancement Root Guard is enabled? ()
A. If BPDUs are not received on a non-designated port, the port is moved into the STP loop- inconsistent blocked state
B. IF BPDUs are received on a PortFast enabled port, the port is disabled.
C. If superior BPDUs are received on a designated port, the interface is placed into the root- inconsistent blocked state.
D. If inferior BPDUs are received on a root port, all blocked ports become alternate paths to the root bride.
