You have configured switches A and B in a network. The gigabitethernet0/1 interface of switch A has HSRP enabled on it for VLAN 30. Switch A has a priority of 240 and switch B has a priority of 200 for the HSRP group. You want to ensure that if the gigabitethernet0/1 interface of switch A goes down, then switch B becomes the active HSRP switch for the VLANs. You have executed the standby preempt command on switch B. Which of the following commands should be used on switch A to achieve the desired results? A. standby 30 track gigabitethernet0/1 B. standby 30 track gigabitethernet0/1 10 C. standby 30 track gigabitethernet0/1 30 D. standby 30 track gigabitethernet0/1 45
D. standby 30 track gigabitethernet0/1 45

A single HSRP group with one active router for the group C. Two HSRP groups, each with an active router D. Two HSRP groups with one active router for both the groups E. Three HSRP groups, each with an active router F. Three HSRP groups with one active router for all groups
E. Three HSRP groups, each with an active router
Interface FastEthernet0/1 is configured as a trunk interface that allows all VLANs. This command is configured globally: monitor session 2 filter vlan 1 - 8, 39, 52 What is the result of the implemented command? A. All VLAN traffic is sent to the SPAN destination interface. B. Traffic from VLAN 4 is not sent to the SPAN destination interface. C. Filtering a trunked SPAN port effectively disables SPAN operations for all VLANs. D. The trunk's native VLAN must be changed to something other than VLAN 1. E. Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.
E. Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.
SIMULATION The headquarter office for a cement manufacturer is installing a temporary Catalyst 3550 in an IDF to connect 24 additional users. To prevent network corruption, it is important to have the correct configuration prior to connecting to the production network. It will be necessary to ensure that the switch does not participate in VTP but forwards VTP advertisements that are received on trunk ports. Because of errors that have been experienced on office computers, all non-trunking interfaces should transition immediately to the forwarding state of DumpsArena - Pass Your Next Certification Exam Fast! dumpsarena.com - Page 117 of 655 Spanning tree. Also configure the user ports (all FastEthernet ports) so that the ports are permanently non-trunking. Requirements: You will configure FastEthernet ports 0/12 through 0/24 for users who belong to VLAN 20. Also all VLAN and VTP configurations are to be completed in global configuration mode as VLAN database mode is being deprecated by Cisco. You are required to accomplish the following tasks: 1. Ensure the switch does not participate in VTP but forwards VTP advertisements received on trunk ports. 2. Ensure all non-trunking interfaces (Fa0/1 to Fa0/24) transition immediately to the forwarding state of Spanning-Tree. 3. Ensure all FastEthernet interfaces are in a permanent non-trunking mode. 4. Place FastEthernet interfaces 0/12 through 0/24 in VLAN 20.
