An infrastructure company is implementing a cabling solution to connect sites on multiple continents. Which of the following cable types should the company use for this project?

Single-mode

Newly crimped 26ft (8m) STP Cat 6 patch cables were recently installed in one room to replace cables that were damaged by a vacuum cleaner. Now, users in that room are unable to connect to the network. A network technician tests the existing cables first. The 177ft (54m) cable that runs from the core switch to the access switch on the floor is working, as is the 115ft (35m) cable run from the access switch to the wall jack in the office. Which of the following is the MOST likely reason the users cannot connect to the network?

An incorrect pinout on the patch cable is being used.

A technician is installing a new fiber connection to a network device in a datacenter. The connection from the device to the switch also traverses a patch panel connection. The chain of connections is in the following order: ✑ Device ✑ LC/LC patch cable ✑ Patch panel ✑ Cross-connect fiber cable ✑ Patch panel ✑ LC/LC patch cable ✑ Switch The connection is not working. The technician has changed both patch cables with known working patch cables. The device had been tested and was working properly before being installed. Which of the following is the MOST likely cause of the issue?

TX/RX is reversed

A new cabling certification is being requested every time a network technician rebuilds one end of a Cat 6 (vendor-certified) cable to create a crossover connection that is used to connect switches. Which of the following would address this issue by allowing the use of the original cable?

MDIX

A technician is installing a cable modem in a SOHO. Which of the following cable types will the technician MOST likely use to connect a modem to the ISP?

Coaxial

A fiber link connecting two campus networks is broken. Which of the following tools should an engineer use to detect the exact break point of the fiber link?

OTDR (Optical Time Domain Reflectometer)

Which of the following connector types would have the MOST flexibility?

SFP

A business is using the local cable company to provide Internet access. Which of the following types of cabling will the cable company MOST likely use from the demarcation point back to the central office?

RG-6

Which of the following cable types would MOST likely be used to provide high-speed network connectivity between nearby buildings?

Fiber

A network technician is manually configuring the network settings for a new device and is told the network block is 192.168.0.0/20. Which of the following subnets should the technician use?

 

255.255.128.0

A client moving into a new office wants the IP network set up to accommodate 412 network-connected devices that are all on the same subnet.

The subnet needs to be as small as possible. Which of the following subnet masks should be used to achieve the required result?

 

255.255.254.0

IPv4 addresses. Instead of receiving the network address and subnet mask, the purchase paperwork indicates the allocation is a /28. This type of notation is referred to as:

CIDR (Classless Inter-Domain Routing)

A user in a branch office reports that access to all files has been lost after receiving a new PC. All other users in the branch can access fileshares.

The IT engineer who is troubleshooting this incident is able to ping the workstation from the branch router, but the machine cannot, ping the

router. Which of the following is MOST likely the cause of the incident?

Incorrect subnet mask

Which of the following commands can be used to display the IP address, subnet address, gateway address, and DNS address on a Window computer?

ipconfig /all

A network administrator used SLAAC in an extensive IPv6 deployment to alleviate IP address management. The devices were properly connected into the LAN but autoconfiguration of the IP address did not occur as expected. Which of the following should the network administrator verify?

 The network gateway is configured to send router advertisements.

A technician is setting up a new router, configuring ports, and allowing access to the Internet. However, none of the users connected to this new router are able to connect to the Internet. Which of the following does the technician need to configure?

 

Network address translation

A network technician needs to determine the IPv6 address of a malicious website. Which of the following record types would provide this information?

AAAA

An administrator is writing a script to periodically log the IPv6 and MAC addresses of all the devices on a network segment. Which of the following switch features will MOST likely be used to assist with this task? (Hint: Similar to ARP, but IPV6)

 

Neighbor Discovery Protocol (IPv4)

A device is connected to a managed Layer 3 network switch. The MAC address of the device is known, but the static IP address assigned to the device is not. Which of the following features of a Layer 3 network switch should be used to determine the IPv4 address of the device?

ARP table

A network architect is developing documentation for an upcoming IPv4/IPv6 dual-stack implementation. The architect wants to shorten the following IPv6 address: ef82:0000:0000:0000:0000:1ab1:1234:1bc2. Which of the following is the MOST appropriate shortened version? (Hint: groups of 0's can be represented by '::' and can only be done once per IPv6 address)

 

ef82::1ab1:1234:1bc2
