What is the maximum number of switches that can be stacked using Cisco StackWise?
The maximum number of switches that can be stacked using Cisco StackWise is 8. Cisco StackWise technology typically supports up to 8 switches in a single stack, allowing them to function as a single logical unit and be managed using a single IP address. This stack can provide redundancy and increased port capacity.
An access switch has been configured with an EtherChannel port. After configuring SPAN to monitor this port, the network administrator notices that not all traffic is being replicated to the management server. What is a cause for this issue?
SPAN encapsulation replication must be enabled to capture EtherChannel destination traffic. Without this configuration, the SPAN session may not replicate all traffic accurately, especially when dealing with EtherChannel ports. This ensures that all replicated traffic from the EtherChannel source port is captured for monitoring.
Which technique allows specific VLANs to be strictly permitted by the administrator?
The technique that allows specific VLANs to be strictly permitted by the administrator is configuring trunk allowed VLANs. This is done by specifying which VLANs are allowed to pass through a trunk port. By default, all VLAN IDs (1 to 4094) are allowed on a trunk, but administrators can customize this list using commands to add or remove specific VLANs from the allowed list. This setup ensures that only the designated VLANs can send and receive traffic through the trunk port, thereby providing strict control over VLAN permissions.
A network engineer is extending a LAN segment between two geographically separated data centers. Which enhancement to a spanning-tree design prevents unnecessary traffic from crossing the extended LAN segment?
To prevent unnecessary traffic from crossing the extended LAN segment, configuring manual trunk pruning between the two locations is the most effective solution. By manually pruning the unnecessary VLANs on the trunk, you can ensure that only required VLANs are allowed to send traffic across the segment, thereby reducing unnecessary spanning-tree instances and enhancing traffic management.
When you design a switched network using VTPv2, how many VLANs can be used to carry user traffic?
VTP versions 1 and 2 support VLAN numbers from 1 to 1001 for normal VLANs. VLANs from 1002 to 1005 are reserved for Token Ring and FDDI, while VLANs from 1006 to 4095 are considered extended range VLANs and are not supported by VTPv1 and VTPv2. Therefore, the number of VLANs that can be used to carry user traffic in a switched network using VTPv2 is 1001.
