Which two types of spanning tree protocols can cause suboptimal traffic flows because they assume only one spanning-tree instance for the entire bridged network? Choose two. Spanning Tree Protocol STP is required to ensure correct network operation when designing a network with multiple interconnected Layer 2 switches or using redundant links to eliminate single points of failure between Layer 2 switches. Routing is a Layer 3 function and does not relate to STP. Which STP priority configuration would ensure that a switch would always be the root switch?

Although the spanning-tree vlan 10 root primary command will ensure a switch will have a bridge priority value lower than other bridges introduced to the network, the spanning-tree vlan 10 priority 0 command ensures the bridge priority takes precedence over all other priorities.

Fill in the blank. Do not use abbreviations. Correct Answer: mode rapid-pvst. Switches configured to operate in a switch stack are connected together through StackWise ports. Refer to the exhibit.

Which trunk link will not forward any traffic after the root bridge election process is complete? S4 has the lowest bridge ID, thus S4 is the root bridge. Which port state will switch ports immediately transition to when configured for PortFast? PortFast allows a switch port to bypass the listening and learning states and transition immediately to the forwarding state. Which switch will be elected the root bridge and which switch will place a port in blocking mode?

The spanning-tree root bridge election process determines which switch becomes root bridge based first on the lowest priority number and then by lowest MAC address. Because all of the switches have the same priority value, SW3 becomes the root bridge based on lowest MAC address. To determine which ports are blocking or forwarding, first determine which ports become the root port on each switch.

Then determine which port becomes the designated port for each link. However, this is accomplished by manually configuring switches to be elected as root bridges for different VLANs on the network. The root bridges are not automatically selected. Furthermore, having spanning-tree instances for each VLAN actually consumes more bandwidth and it increases the CPU cycles for all the switches in the network. To obtain an overview of the spanning tree status of a switched network, a network engineer issues the show spanning-tree command on a switch.

Which two items of information will this command display?

It does not show the number of broadcast packets received on the ports. Link types can be either point-to-point, shared, or edge. If no bridge priority is configured in PVST, which criteria is considered when electing the root bridge? Only one switch can be the root bridge for a VLAN. The root bridge is the switch with the lowest BID.

If no priority is configured then all switches use the default priority and the election of the root bridge will be based on the lowest MAC address. When the network is saturated with broadcast traffic that is looping between switches, new traffic is discarded by each switch because it is unable to be processed.We will update answers for you in the shortest time.

Thank you! We truly value your contribution to the website. Which dynamic routing protocol was developed to interconnect different Internet service providers? Which routing protocol is limited to smaller network implementations because it does not accommodate growth for larger networks?

The RIP protocol was created with a metric that does not support larger networks. When would it be more beneficial to use a dynamic routing protocol instead of static routing? Dynamic routing protocols consume more router resources, are suitable for larger networks, and are more useful on networks that are growing and changing. When would it be more beneficial to use static routing instead of dynamic routing protocols? Dynamic routing protocols are viewed as less secure than static routing because they commonly forward routing information on the same links that data traffic is crossing.

What is a purpose of the network command when configuring RIPv2 as the routing protocol? The network command is used to advertise the directly connected networks of a router. It enables RIP on the interfaces that belong to the specified network. A network administrator configures a static route on the edge router of a network to assign a gateway of last resort. How would a network administrator configure the edge router to automatically share this route within RIP?

Which route would be automatically created when a router interface is activated and configured with an IP address? Directly connected networks are identified with a C and are automatically created whenever an interface is configured with an IP address and activated. Refer to the exhibit. Which two types of routes could be used to describe the Choose two.

A level 2 child route is a route that has a network with a mask that is greater than the classful equivalent. An ultimate route is a route that uses a next-hop IP address or exit interface to forward traffic. What occurs next in the router lookup process after a router identifies a destination IP address and locates a matching level 1 parent route?

When a router locates a parent route that matches the destination IP address of a packet, the router will then examine the level 2 child routes contained within it.

Which route would be used to forward a packet with a source IP address of Even though OSPF has a higher administrative distance value less trustworthythe best match is the route in the routing table that has the most number of far left matching bits. An ultimate route is a routing table entry that contains either a next-hop IP address another path or an exit interface, or both. This means that directly connected and link-local routes are ultimate routes. A default route is a level 1 ultimate route, but not all ultimate routes are default routes.

Routing table entries that are subnetted are level 1 parent routes but do not meet either of the two requirements to be ultimate routes. Ultimate routes do not have to be classful network entries. By default, dynamic routing protocols forward messages across a network without authenticating the receiver or originator of traffic.

Static routes increase in configuration complexity as the network grows larger and are more suitable for smaller networks.

Static routes also require manual intervention when a network topology changes or links become disabled. Which two statements are true regarding classless routing protocols?MAC address. IP address Refer to the exhibit. Which trunk link will not forward any traffic after the root bridge election process is complete?

Do not use abbreviations. Correct Answer: mode rapid-pvst What port type is used to interconnect switches in a switch stack? MST Which two types of spanning tree protocols can cause suboptimal traffic flows because they assume only one spanning-tree instance for the entire bridged network? Choose two. Which switch will be elected the root bridge and which switch will place a port in blocking mode?

SW4 will get a port blocked. Which two items of information will this command display? The status of native VLAN ports. Link types can only be determined if PortFast has been configured. Link types can only be configured on access ports configured with a single VLAN. If no bridge priority is configured in PVST, which criteria is considered when electing the root bridge? ARP broadcast requests are returned to the transmitting host.

Version 5. In order for two computers to be able to communicate effectively, there must be a mechanism that allows both the source and destination to set the timing of the transmission and receipt of data. Flow control allows for this by ensuring that data is not sent too fast for it to be received properly.

Broadcast communication is a one-to-all communication. A unicast communication is a one-to-one communication. Multicast is a one-to-many communication where the message is delivered to a specific group of hosts. Allcast is not a standard term to describe message delivery. Encapsulation is the process of placing one message format into another message format.It is designed to provide an additional opportunity to practice the skills and knowledge presented in the chapter and to prepare for the Chapter 3 Exam.

Explanation : When all devices need to receive the same message simultaneously, the message would be delivered as a broadcast. Unicast delivery occurs when one source host sends a message to one destination host.

The sending of the same message from a host to a group of destination hosts is multicast delivery. Duplex communications refers to the ability of the medium to carry messages in both directions. The internet layer determines the best path through the network.

Explanation : Physical addresses are encapsulated at the data link layer. Logical addresses, also known as IP addresses, are encapsulated at the network layer. Port addresses are encapsulated at the transport layer. No addresses are encapsulated at the physical layer.

The host is unable to communicate on the local network. The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks. There is no impact on communications. Explanation : A default gateway is only required to communicate with devices on another network.

The absence of a default gateway does not affect connectivity between devices on the same local network. Explanation : The protocols used in network communications define the details of how a message is transmitted, including requirements for message delivery options, message timing, message encoding, formatting and encapsulation, and message size. Explanation : The term protocol data unit PDU is used to describe a piece of data at any layer of a networking model.

A packet is the PDU at the network layer. A frame is the data link layer PDU. A segment is the PDU at the transport layer. Explanation : Protocols provide rules that define how a message is transmitted across a network. Implementation requirements such as electronic and bandwidth details for data communication are specified by standards.

Operating systems are not specified by protocols, but will implement protocols. Protocols determine how and when to send a message but they do not control the contents of a message. Explanation : The OSI model consists of seven layers: application, presentation, session, transport, network, data link, and physical.

The transport layer defines services to segment, transfer, and reassemble the data for individual communications between the end devices. They are required for devices to gain access to the Internet.Clean the CPU and the base of the heat sink with isopropyl alcohol before applying the thermal compound.
