The broadcast domain expands to all switches. One collision domain exists per switch. Frame collisions increase on the segments connecting the switches. There is one broadcast domain and one collision domain per switch. In Cisco LAN switches, the microsegmentation makes it possible for each port to represent a separate segment and thus each switch port represents a separate collision domain.- This fact will not change when multiple switches are interconnected. However, LAN switches do not filter broadcast frames. A broadcast frame is flooded to all ports. Interconnected switches form one big broadcast domain. A one rack unit access switch can have up to 48 ports. Larger switches may support hundreds of ports. What are two reasons a network administrator would segment a network with a Layer 2 switch? Choose two. The two devices have full-bandwidth full-duplex connectivity during the transmission. Fill in the blank. A converged network is one that uses the same infrastructure to carry voice, data, and video signals. Match the borderless switched network guideline description to the principle. Not all options are used. Match the functions to the corresponding layers. Match the forwarding characteristic to its type.

As data travels on the media in a stream of 1s and 0s how does a receiving node identify the beginning and end of a frame? The transmitting node inserts start and stop bits into the frame. The transmitting node sends a beacon to notify that a data frame is attached. The receiving node identifies the beginning of a frame by seeing a physical address. The transmitting node sends an out-of-band signal to the receiver about the beginning of the frame. Explanation: When data travels on the media, it is converted into a stream of 1s and 0s. The framing process inserts into the frame start and stop indicator flags so that the destination can detect the beginning and end of the frame. If the two values do not match, then the frame is discarded. Fill in the blank. What acronym is used to reference the data link sublayer that identifies the network layer protocol encapsulated in the frame? LLC Fill in the blank. A physical topology that is a variation or combination of a point-to-point, hub and spoke, or mesh topology is commonly known as a hybrid topology.- Match the characteristics to the correct type of fiber. Not all options are used. Its small core produces a single straight path for light and it is commonly used with campus backbones. Multimode fiber uses LEDs as the light source. Its larger core allows for multiple paths for the light. It is commonly used with LANs. What is the definition of bandwidth? It is the amount of data that can move between two points on the network over a specific period of time, typically one second.
- What is a role of the Logical Link Control sublayer? The LLC sublayer is responsible for communicating with the network layer and for tagging frames to identify what Layer 3 protocol is encapsulated. What are two examples of hybrid topologies? Choose two.

What is the purpose of HSRP? It provides a continuous network connection when a router fails. It prevents malicious hosts from connecting to trunk ports. It enables an access port to immediately transition to the forwarding state. Refer to the exhibit. What is the problem? The switch ports have to be configured as access ports with each port having a VLAN assigned. The interface port-channel number has to be different on each switch. The switch ports were not configured with speed and duplex mode.- What is an advantage of using LACP? What is a requirement to configure a trunking EtherChannel between two switches? The participating interfaces must be assigned the same VLAN number on both switches. The participating interfaces must be on the same module on a switch. The participating interfaces must be physically contiguous on a switch. The allowed range of VLANs must be the same on both switches. A network administrator would like to ensure that router R1 is always elected the active router for an HSRP group. Which set of commands would ensure the required results? R1 config-if ip address After the routers have been reloaded, a user on Host1 complained of lack of connectivity to the Internet The network administrator issued the show standby briefcommand on both routers to verify the HSRP operations.

In addition, the administrator observed the ARP table on Host1. Fill in the blank. What is a best practice to use before beginning an EtherChannel implementation? Enable each of the affected interfaces. Assign affected interfaces to the management VLAN. Shut down each of the affected interfaces. Assign affected interfaces to an unused VLAN. Which statement describes an EtherChannel implementation? EtherChannel operates only at Layer 2. A trunked port can be part of an EtherChannel bundle. PAgP cannot be used in conjunction with EtherChannel. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What are two reasons why the ping messages that are issued from Laptop0 towards Laptop1 are failing?- Choose two. The two interfaces on each of the switches belong to different VLANs. The channel group mode is not set correctly on the switches. The wrong cable types are connecting the two switches. The channel group should be configured as a trunk on each switch. A network administrator issued the show etherchannel summarycommand on the switch S1. What conclusion can be drawn? The EtherChannel is not functional. The port aggregation protocol PAgP is misconfigured.
- What statement is true about the output of the show standby command? The current priority of this router is This router is tracking two properly operating interfaces. This router is in the HSRP down state because its tracked interfaces are down. The router is currently forwarding packets. Which three options must match in order to establish an EtherChannel between two directly connected switches? Choose three. Which two protocols are used to implement EtherChannel?
- Which action does the router take after inbound-to-outbound traffic is inspected and a new entry is created in the state table? When traffic returns from its destination, it is reinspected, and a new entry is added to the state table. A dynamic ACL entry is added to the external interface in the inbound direction. The entry remains in the state table after the session is terminated so that it can be reused by the host. Traffic that originates from the inside interface is generally blocked entirely or very selectively permitted to the outside interface.
- Return traffic from the inside that is associated with traffic originating from the outside is permitted to traverse from the inside interface to the outside interface. Return traffic from the outside that is associated with traffic originating from the inside is permitted to traverse from the outside interface to the DMZ interface. Traffic that originates from the outside interface is permitted to traverse the firewall to the inside interface with few or no restrictions.

Traffic that originates from the DMZ interface is selectively permitted to the outside interface. Which statement best describes this implementation? The two models cannot be implemented on a single interface. An interface must be assigned to a security zone before IP inspection can occur. Both models must be implemented on all interfaces.IT Essentials Chapter 4 Exam Answers Version % - Premium IT Exam Answers
The decisions are based on the ingress port and the destination MAC address of the frame. The ingress port information is important because it carries the VLAN to which the port belongs. Refer to the exhibit. Consider that the main power has just been restored. To which port will SW1 forward this request? What is one function of a Layer 2 switch? To forward a frame onward, the switch examines the destination MAC address, looks in the MAC address for a port number associated with that destination MAC address, and sends it to the specific port. If the destination MAC address is not in the table, the switch forwards the frame out all ports except the inbound port that originated the frame. CCNA2 v6. SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch. SW1 forwards the frame directly to SW2. SW2 floods the frame to all ports connected to SW2, excluding the port through which the frame entered the switch. SW1 drops the frame because it does not know the destination MAC address.CCNA 1 (v5.1 + V6.0) Chapter 4 Exam Answers For Network Access
Explanation: When a switch powers on, the MAC address table is empty. The switch forwards based on the destination MAC address found in the frame header. If a switch has no entries in the MAC address table or if the destination MAC address is not in the switch table, the switch will forward the frame out all ports except the port that brought the frame into the switch. A small publishing company has a network design such that when a broadcast is sent on the LAN, devices receive the transmitted broadcast.Linux Essentials Chapter 4 Exam Answers - CCNA 7 Exam Answers
How can the network administrator reduce the number of devices that receive broadcast traffic? Add more switches so that fewer devices are on a particular switch. Replace the switches with switches that have more ports per switch. This will allow more devices on a particular switch. Replace at least half of the switches with hubs to reduce the size of the broadcast domain. Explanation: By dividing the one big network into two smaller network, the network administrator has created two smaller broadcast domains. When a broadcast is sent on the network now, the broadcast will only be sent to the devices on the same Ethernet LAN. The other LAN will not receive the broadcast. How many broadcast domains are displayed?- In the exhibit, 4 links between routers make 4 broadcast domains. Also, each LAN that is connected to a router is a broadcast domain. The 4 LANs in the exhibit result in 4 more broadcast domains, so there are 8 broadcast domains in all. Which solution would help a college alleviate network congestion due to collisions?
