Tree protocol root guard feature be implemented? (Choose two) A. On the designated root switch downlinks to the access layer. B. On all of non-root switch facing ports of the access layer C. On the access layers root facing ports D. On Layer 3 boundaries in the distribution layer E. Globally on all network switches. Answer: A B Question 4 Where should the Root Guard be implemented in the network topology that Cisco recommends? (Choose two) A. All non-root ports of the Access Switches. B. Downstream links from Distribution to Access Switches C. Access Switches to uplink ports to Distribution Switches D. On Layer 3 Switches. Answer: A B Question 5 Which command enables root guard on a Cisco switch? A. Switch(config)#spanning-tree guard root B. Switch(config)#spanning-tree root guard C. Switch(config-if)#spanning-tree guard-root D. Switch(config-if)#spanning-tree guard root E. Switch(config-if)#spanning-tree root guardn Answer: D Question 6 Which feature do you implement so that an interface enters the root inconsistent state if it receives a superior BPDU? A. DPDU guard B. root guard

C. BPDU guard D. loop guard Answer: B Question 7 Which command is required for root guard for Cisco device to place ID:2071948x? (Where x is the last digit ID) A. (config if)# spanning-tree guard root B. (config)# spanning-tree guard root C. (config-if)# spanning-tree root guard D. (config)# spanning-tree root guard Answer: A RSTP Questions Question 1 After the recent upgrade of the switching infrastructure, the network engineer notices that the port roles that were once ―blocking‖ are now defined as ―alternate‖ and ―backup‖. What is the reason for this change? A. The new switches are using RSTP instead of legacy IEEE 802.1D STP. B. IEEE 802.1D STP and PortFast have been configured by default on all newly implemented Cisco Catalyst switches. C. The administrator has defined the switch as the root in the STP domain. D. The port roles have been adjusted based on the interface bandwidth and timers of the new Cisco Catalyst switches. Answer: A Question 2 What happens on a Cisco switch that runs Cisco IOS when an RSTP-configured switch receives 802.1d BPDU? A. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives an 802.1d BPDU, it responds with an 802.1d BPDU and eventually the

two switches run 802.1d to communicate. B. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it responds with a 802.1d BPDU and eventually the two switches run 802.1d to communicate. C. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU. D. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.
