A user is executing a tracert to a remote device. At what point would a router, which is in the path to the destination device, stop forwarding the packet?

• when the router receives an ICMP Time Exceeded message

• when the RTT value reaches zero

• when the host responds with an ICMP Echo Reply message

• when the values of both the Echo Request and Echo Reply messages reach zero

Refer to the exhibit. What is wrong with the displayed termination?

• The woven copper braid should not have been removed.

• The wrong type of connector is being used.

• The untwisted length of each wire is too long.

Refer to the exhibit. The network administrator has assigned the LAN of LBMISS an address range of 192.168.10.0. This address range has been subnetted using a /29 prefix. In order to accommodate a new building, the technician has decided to use the fifth subnet for configuring the new network (subnet zero is the first subnet). By company policies, the router interface is always assigned the first usable host address and the workgroup server is given the last usable host address. Which configuration should be entered into the properties of the workgroup server to allow connectivity to the Internet?

• IP address: 192.168.10.65 subnet mask: 255.255.255.240, default gateway: 192.168.10.76

• IP address: 192.168.10.38 subnet mask: 255.255.255.240, default gateway: 192.168.10.33

• IP address: 192.168.10.38 subnet mask: 255.255.255.248, default gateway: 192.168.10.33

• IP address: 192.168.10.41 subnet mask: 255.255.255.248, default gateway: 192.168.10.46

• IP address: 192.168.10.254 subnet mask: 255.255.255.0, default gateway: 192.168.10.1

Refer to the exhibit. The switches are in their default configuration. Host A needs to communicate with host D, but host A does not have the MAC address for its default gateway. Which network hosts will receive the ARP request sent by host A?

• only hosts B and C

• only router R1

• only hosts A, B, and C

• only hosts A, B, C, and D

• only hosts B, C, and router R1

Which two traffic types use the Real-Time Transport Protocol (RTP)? (Choose two.)

• video

• web

• file transfer

• voice

• peer to peer

Which wireless technology has low-power and data rate requirements making it popular in home automation applications?

• ZigBee

• LoRaWAN

• 5G

• Wi-Fi
