• virus

• worm

• phishing

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 value in the TTL field reaches zero

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

A network technician is researching the use of fiber optic cabling in a new technology center. Which two issues should be considered before implementing fiber optic media? (Choose two.)

• Fiber optic cabling requires different termination and splicing expertise from what copper cabling requires

• Fiber optic cabling requires specific grounding to be immune to EMI.

• Fiber optic cabling is susceptible to loss of signal due to RFI.

• Fiber optic cable is able to withstand rough handling.

• Fiber optic provides higher data capacity but is more expensive than copper cabling.

Which value, that is contained in an IPv4 header field, is decremented by each router that receives a packet?

• Header Length

• Differentiated Services

• Time-to-Live

• Fragment Offset

A user is complaining that an external web page is taking longer than normal to load.The web page does eventually load on the user machine. Which tool should the technician use with administrator privileges in order to locate where the issue is in the network?

• ping

• nslookup

• tracert

• ipconfig/displaydns

What two pieces of information are displayed in the output of the show ip interface brief command? (Choose two.)

A network administrator wants to have the same subnet mask for three subnetworks at a small site. The site has the following networks and numbers of devices:

Subnetwork A: IP phones – 10 addresses 

Subnetwork B: PCs – 8 addresses 

Subnetwork C: Printers – 2 addresses 

What single subnet mask would be appropriate to use for the three subnetworks?

• 255.255.255.0

• 255.255.255.240

• 255.255.255.248

• 255.255.255.252

Refer to the exhibit. A company uses the address block of 128.107.0.0/16 for its network. What subnet mask would provide the maximum number of equal size subnets while providing enough host addresses for each subnet in the exhibit?

• 255.255.255.192

• 255.255.255.0

• 255.255.255.128

• 255.255.255.240

• 255.255.255.224

Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)

• The source port field identifies the running application or service that will handle data returning to the PC.

• The TCP process running on the PC randomly selects the destination port when establishing a session with the server.

• UDP segments are encapsulated within IP packets for transport across the network.

• The UDP destination port number identifies the application or service on the server which will handle the data.

• TCP is the preferred protocol when a function requires lower network overhead.

What is an advantage to using a protocol that is defined by an open standard?

• A company can monopolize the market.

• The protocol can only be run on equipment from a specific vendor

• An open standard protocol is not controlled or regulated by standards organizations

• It encourages competition and promotes choices
