If the building will be air conditioned as well as heated, increase the allow-able length by 15 (provided the environmental control system will run. If the building will be heated only and will have hinged-column bases, use the allowable length as specified. When other conditions prevail, the following rules are applicable: 1.The frame is broadcast to all other devices on the same network. The frame is returned to the originating network device. What happens to runt frames received by a Cisco Ethernet switch? The LENGTH field is the length of the user datagram including the header, that is the. 6Read Chapter wise CCNA 1 Exam Answers (v5.1 + v6.0) CCNA 1 Chapter 5 Exam Answers 2020This leaves the following topics as sections in this document. IEEE Std 802.3-2012, subclause 3.2.9 - Frame Check Sequence (FCS) field.CCNA 1 (v5.1 + v6.0) Chapter 5 Exam Answers for EthernetIt is set to 1 in a QoS data or management frame transmitting at HT or higher rate to indicate that the frame contains HT Control field (see above) IEEE 802.11bf edit IEEE 802.11bf is a mature standard 4 5 that is capable to 'to measure the range, velocity, direction, motion, presence, and proximity of people and objects'.Which two statements describe features or functions of the logical link control sublayer in Ethernet standards? (Choose two.) It connects multiple sites such as routers located in different countries.4. It defines a standard model used to describe how networking works. It is the required Layer 1 and 2 standard for Internet communication. It defines the most common LAN type in the world.* What are the two sizes (minimum and maximum) of an Ethernet frame? (Choose two.)
The data link layer uses LLC to communicate with the upper layers of the protocol suite.* The LLC sublayer adds a header and a trailer to the data. Logical link control is specified in the IEEE 802.3 standard. MAC addresses are implemented by software. Which statement is true about MAC addresses? They are added as part of a Layer 3 PDU.6. They are only routable within the private network. What statement describes a characteristic of MAC addresses? The exhibit shows a small switched network and the contents of the MAC address table of the switch. the source Layer 2 address of incoming frames*9. the source Layer 3 address of outgoing packets Gba emulator for mac os x 106Which switching method uses the CRC value in a frame? The switch will forward the frame only to ports 1 and 3.10. The switch will forward the frame to all ports. The switch will forward the frame to all ports except port 4.* The switch will forward the frame only to port 2. What will the switch do with the frame? RT1 will send an ARP reply with the PC2 MAC address. RT1 will send an ARP reply with its Fa0/0 MAC address. PC2 will send an ARP reply with its MAC address.* In this scenario, what will happen next? PC1 issues an ARP request because it needs to send a packet to PC2. Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network. Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic.* On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays. Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing. What are two potential network problems that can result from ARP operation? (Choose two.) SW1 will send an ARP reply with its Fa0/1 MAC address.13. Which network hosts will receive the ARP request sent by host A?A switch with a default configuration connects four hosts. Host A needs to communicate with host D, but host A does not have the MAC address for its default gateway. Which statement describes the treatment of ARP requests on the local link?They must be forwarded by all routers on the local network.They are received and processed by every device on the local network.*They are dropped by all switches on the local network.They are received and processed only by the target device.The switches are in their default configuration. The aim is to associate IP addresses to the wrong MAC addresses.17. Best app for recording camera on macEvery other host connected to the switch receives the broadcast and host D responds with its MAC address.*When a device is sending data to another device on a remote network, the Ethernet frame is sent to the MAC address of the default gateway.21. The switch sends the packet only to the host D, which in turn responds.Host A sends out a broadcast of FF:FF:FF:FF:FF:FF. What happens when host A wants to send an IP packet to host D?Host A sends an ARP request to the MAC address of host D.Host A sends out the packet to the switch. It processes more overhead than the controlled access methods do. What is a characteristic of a contention-based access method? (Not all options are used.)Cut-through (B) -> may forward runt frames (B)*Cut-through (C) -> begins forwarding when the destination address is received (C)*Store-and-forward (D) -> always stores the entire frame (D)*Store-and-forward (E) -> checks the CRC before forwarding (E)*Store-and-forward (F) -> checks the frame length before forwarding (F)23. Match the characteristic to the forwarding method. Which two statements are correct about MAC and IP addresses during data transmission if NAT is not involved? (Choose two.) What is the Layer 2 multicast MAC address that corresponds to the Layer 3 IPv4 multicast address 224.139.34.56?26. is used to identify the destination address25. What is the purpose of the preamble in an Ethernet frame? It scales very well under heavy media use.24. If a host is ready to send a packet to a local destination device and it has the IP address but not the MAC address of the destination, it generates an ARP broadcast.* What are two features of ARP? (Choose two.) Every time a frame is encapsulated with a new destination MAC address, a new destination IP address is needed.27. Destination IP addresses in a packet header remain constant along the entire path to a target host.* Destination and source MAC addresses have local significance and change every time a frame goes from one LAN to another. Destination MAC addresses will never change in a frame that goes across seven routers. A host is trying to send a packet to a device on a remote LAN segment, but there are currently no mappings in its ARP cache. If a device receiving an ARP request has the destination IPv4 address, it responds with an ARP reply.*28. If no device responds to the ARP request, then the originating node will broadcast the data packet to all devices on the network segment. When a host is encapsulating a packet into a frame, it refers to the MAC address table to determine the mapping of IP addresses to MAC addresses. It will send the frame with a broadcast MAC address. It will send the frame and use its own MAC address as the destination. * It will send an ARP request for the MAC address of the default gateway. It will send an ARP request for the MAC address of the destination device. 111111111111111111111111111111If both switches support different speeds, they will each work at their own fastest speed. The link between switches will work as full-duplex.* The link between the switches will work at the fastest speed that is supported by both switches. Which three statements are correct about the final result of the connection? (Choose three.) The switches are new and have never been configured. A network administrator is connecting two modern switches using a straight-through cable.
