                                                  Which subnet would include the address 192.168.1.96 as a usable host address?
                                                  Correct

                                                  Incorrect

                                                  For the subnet of 192.168.1.64/26, there are 6 bits for host addresses, yielding 64 possible addresses. However, the first and last subnets are the network and broadcast addresses for this subnet. Therefore, the range of host addresses for this subnet is 192.168.1.65 to 192.168.1.126. The other subnets do not contain the address 192.168.1.96 as a valid host address.

                                                  Incorrect

                                                  Each service provided by a server, such as email or file transfers, uses a specific port number. The source port number of a service request identifies the client that is requesting services. The destination port number identifies the specific service. Servers do not use address information to provide services. Routers and switches use addressing information to move traffic through the network.

                                                  In an Ethernet network, each NIC in the network checks every arriving frame to see if the destination MAC address in the frame matches its own MAC address. If there is no match, the device discards the frame. If there is a match, the NIC passes the frame up to the next OSI layer.

                                                  Which connection provides a secure CLI session with encryption to a Cisco switch?
                                                  Correct

                                                  Incorrect

                                                  A CLI session using Secure Shell (SSH) provides enhanced security because SSH supports strong passwords and encryption during the transport of session data. The other methods support authentication but not encryption.

                                                  Hint

                                                  3 points
                                                  What are the three ranges of IP addresses that are reserved for internal private use? (Choose three.)
                                                  Correct

                                                  Incorrect

                                                  The private IP address blocks that are used inside companies are as follows:

                                                  • 10.0.0.0 /8 (any address that starts with 10 in the first octet)
                                                  • 172.16.0.0 /12 (any address that starts with 172.16 in the first two octets through 172.31.255.255)
                                                  • 192.168.0.0 /16 (any address that starts with 192.168 in the first two octets)

                                                  38. Question

                                                  What statement describes the function of the Address Resolution Protocol?
                                                  Correct

                                                  Incorrect

                                                  When a PC wants to send data on the network, it always knows the IP address of the destination. However, it also needs to discover the MAC address of the destination. ARP is the protocol that is used to discover the MAC address of a host that belongs to the same network.

                                                  Hint

                                                  1 points
                                                  What is the purpose of having a converged network?
                                                  Correct

                                                  Incorrect

                                                  With the development of technology, companies can now consolidate disparate networks onto one platform called a converged network. In a converged network, voice, video, and data travel over the same network, thus eliminating the need to create and maintain separate networks. This also reduces the costs associated with providing and maintaining the communication network infrastructure.
