Routing should be configured without traffic filtering, address translation, or other packet manipulation at the core. The core, which acts as the front door to a network, is designed to prevent unauthorized users from gaining entry.
The core provides an optimized and reliable transport structure by using a combination of route summaries, distribution lists, and route exak. The QoS requirements should accommodate the smooth demand on bandwidth, low latency, and delay for voice traffic. UDLD sends hello messages to its neighbor at a rate of one per second to attempt to recover the connection. Create voice VLANs to keep voice traffic separate from other data to ensure special handling of the traffic.
Configure QoS policy to classify the voice traffic in the priority queue to guarantee reserved bandwidth allocation for the traffic. Configure the Weighted Random Early Detection WRED congestion avoidance mechanism to guarantee that the voice traffic will be placed in the priority queue. PortFast should be implemented on the uplink ports from the access switches to the distribution switches. Loop guard should be implemented on the Layer 2 ports between DSW1 essitching DSW2 and on the uplink ports from the access switches to the distribution switches.
To create a routed port requires removal of Layer 2 port functionality with anzwers no switchport interface configuration command. If the DSw1 switch is configured with the standby preempt command and DSw2 is not, then DSw1 will be the active router.
When host A sends an Exxm request for Decisions on which port to block when two ports have equal cost depend on the port priority and index. The difference in BPDUs sent and received indicates a loop caused by unidirectional link failure has been eswitcning.

STP can be active in the distribution layer, but is unaware of any FlexLink updates in the access layer. It will increase the number of additional links that are required to provide redundant connectivity. BPDU guard overrides the PortFast configuration and reverts to the default spanning tree configuration on the access ports. Configure switch virtual interfaces. The result is that the router will have a virtual interface in each VLAN. Edge ports never generate topology change notifications TCNs when the port transitions to a disabled or enabled status.
Edge ports can have another switch connected to them as long as the link is operating in full duplex. Wide coverage because of the fact that a VLAN can be geographically dispersed throughout the network.
When mixed video and voice packets are included in the video stream, the latency should be ms. Survey Maker Flashcards See All. Please take the quiz to rate it.

During the Quiz End of Quiz. Title of New Duplicated Quiz:. A copy of this quiz is in your dashboard. Go to My Dashboard. Removing question excerpt is a premium feature. Refer to the exhibit. Given the output of the show standby brief command on RTA, what is the cause of the problem? The command standby preempt should only be applied on the active router. The group number 50 is missing in the Router RTB configuration commands.
The priority number is missing in the Router RTB configuration commands. The ports on the switch must be configured with the spanning-tree PortFast feature. All intercepted packets that come from trusted ports are sent to untrusted ports only.

When a port security violation occurs on a switch port, the switch sends a syslog message but does not shut down the port. What port security mode is in effect? Which three steps are required to configure interfaces as routed ports on a multilayer Catalyst switch? Disable Layer 2 functionality on interfaces that will be configured as routed ports. A bridging loop occurs in a network and disrupts user connectivity.
What action should be taken by a network administrator to restore connectivity? Disable all ports on the distribution switches and replace with new switches. Which three actions can cause problems with a VTP implementation? Using lowercase on one switch and uppercase on another switch for domain names. What two conclusions can be made based on the output? The Cost column in the lower part of the exhibit is not the cumulative root path cost. The QoS requirements should accommodate the best effort delivery for voice traffic.
The QoS requirements should accommodate the bursty nature of voice traffic. The QoS requirements should accommodate the intensive demand on bandwidth for voice traffic.
When troubleshooting GLBP in an environment with a VLAN that spans multiple access layer switches, a network engineer discovers that suboptimal paths are being used for upstream traffic.
What is the recommended solution? Which two procedures should be implemented and in place when deploying VoIP in a campus network?
Keep voice and data traffic in the same VLAN and mark the traffic for high priority treatment. Answres traffic shaping QoS policy to guarantee minimum delay for the voice traffic. Finnal are three possible misconfigurations or indicators of misconfigurations on a Layer 3 interface? What type of queuing provides the best quality for voice applications?
What is the problem between the connection on Switch1 and Switch2? The exhibit contains the configuration for a Cisco access device. How will someone dialing in be authenticated?
Which STP enhancement should be configured in the network to prevent a nondesignated port to transition to a forwarding state when a topology change occurs?
Root guard should be implemented on the Layer 2 ports between the distribution switches. What are two actions a hacker may take in a VLAN hopping attack? Sending a unicast flood of Ethernet frames with distinct source MAC addresses. A network administrator wants to implement inter-VLAN routing in the network.
Which interfaces should be configured as routed ports? Which three actions are taken when the command switchport host is entered on a switch port? Which two statements are true about routed ports on a multilayer switch? A routed port behaves like a regular router interface and supports VLAN subinterfaces.
