27. In what two situations would UDP be better than TCP as the preferred transport protocol? (Choose two.)

when applications need to guarantee that a packet arrives intact, in sequence, and unduplicated
when a faster delivery mechanism is needed
when delivery overhead is not an issue
when applications do not need to guarantee delivery of the data
when destination port numbers are dynamic

Explanation: UDP is a very simple transport layer protocol that does not guarantee delivery. Devices on both ends of the conversation are not required to keep track of the conversation. UDP is used as the transport protocol for applications that need a speedy, best-effort delivery.

28. The current IP configuration of a small company is done manually and is time-consuming. Because of increased network growth, a technician needs a simpler way for IP configuration of workstations. Which service would simplify the workstation IP configuration task?

APIPA
DHCP
DNS
ICMP

Explanation: In networks with more than a few hosts, DHCP simplifies the addressing process. A DHCP server automatically assigns host IP addresses.

29. A company is looking for a next-generation firewall that provides VPN functionality, IDS/IPS functionality, and DoS/DDoS protection. Which device would be best suited for this task?

multipurpose device
router
endpoint management server
UTM

30. A student is helping a friend with a home computer that can no longer access the Internet. Upon investigation, the student discovers that the computer has been assigned the IP address 169.254.100.88. What could cause a computer to get such an IP address?

static IP addressing with incomplete information
interference from surrounding devices
reduced computer power supply output
unreachable DHCP server

Explanation: When a PC does not have a static IP address or cannot pick one up from a DHCP server, Windows will automatically assign the PC an IP address using APIPA, that uses the range of addresses 169.254.0.0 to 169.254.255.255.

31. What three values must be added to the IPv4 properties of a NIC in order for a computer to have basic connectivity with the network? (Choose three.)

subnet mask
DHCP server address
domain name
default gateway
speed and duplex
IP address

Explanation: The IP address, subnet mask, and default gateway address values should be added to the NIC properties in order for the computer to have basic network connectivity. This can be done either statically or dynamically with DHCP. An additional value that should be present if the computer is to be used to connect to the Internet is the DNS server value. A computer automatically attempts to locate a DHCP server if configured to do so. A DHCP server address is not used. Finally, NAT is configured on a router, not on a computer host, and speed and duplex settings are NIC hardware settings and not IPv4 properties of the NIC.

32. A device has an IPv6 address of 2001:0DB8:75a3:0214:0607:1234:aa10:ba01 /64. What is the host identifier of the device?

2001:0DB8:75a3
0607:1234:aa10:ba01
2001:0DB8
ba01

Explanation: An IPv6 address is made up of 128 bits that are represented as eight blocks of four hexadecimal digits that are called hextets. Because each hexadecimal digit represents four bits, each hextet represents 16 bits. The /64 network prefix indicates that the first 64 bits, or first four hextets, represent the network portion of the address. Because there are 128 bits in an IPv6 address, this leaves the last 64 bits, or last four hextets, to represent the host identifier. The value for the last four hextets is 0607:1234:aa10:ba01.

33. How can a user prevent specific applications from accessing a Windows computer over a network?

Enable MAC address filtering.
Disable automatic IP address assignment.
Block specific TCP or UDP ports in Windows Firewall.
Change default usernames and passwords.

Explanation: Network applications have specific TCP or UDP ports that can be left open or blocked in Windows Firewall. Disabling automatic IP address assignment may result in the computer not being able to connect to the network at all. Enabling MAC address filtering is not possible in Windows and would only block specific network hosts, not applications. Changing default usernames and passwords will secure the computer from unauthorized users, not from applications.

pages 1, 2, 3, 1, 2, 3
pages 3, 3, 2, 2, 1, 1
pages 3, 2, 1, 3, 2, 1

Explanation: The collate feature enables a printer to sort multiple copies of a document with the proper page order for each copy.

42. A color laser printer is used to print documents with graphics and photographs. Users are complaining that printing takes too long. Which component of the printer should be upgraded in order to improve printing performance?

CPU
RAM
hard drive
toner cartridges

Explanation: Because documents with graphics and photographs generate much larger print jobs, the printing process will run more efficiently if the printer memory is adequate to store the entire job before the job starts.

43. What service is available for Windows to provide software print server services to MAC OS clients?

Bonjour Print Server
Print to XPS
Apple AirPort Extreme
Apple AirPrint

Explanation: Bonjour Printer Server from Apple comes with MAC OS X and is a free download for Windows users to be used as a software print server. Airport Extreme, a dedicated print server, and a PC with a printer attached serving as a print server are all hardware print sharing solutions.

44. Which three components are typically found in laser printer maintenance kits? (Choose three.)

fuser assembly
primary corona
pickup rollers
transfer rollers
secondary corona
paper trays

Explanation: Laser printer maintenance kits typically contain components that wear and can be installed with minimal disassembly of the printer. Corona wires are internal components that would require a trained technician to replace. Paper trays are components that are not typically replaced during maintenance, but would be replaced any time if damaged.

45. A technician is installing a new printer in a cool, damp environment. After the printer cabling is done, and the software and print driver are installed, the printer test page jams. What is the most likely cause of the print failure?

incorrect printer driver

loose printer cables

Explanation: Paper jams are commonly caused when the paper being used is dirty, affected by humidity, or is the wrong type of paper for the printer.

46. A data center has recently updated a physical server to host multiple operating systems on a single CPU. The data center can now provide each customer with a separate web server without having to allocate an actual discrete server for each customer. What is the networking trend that is being implemented by the data center in this situation?

BYOD
virtualization
maintaining communication integrity
online collaboration

Explanation: Virtualization technology can run several different operating systems in parallel on a single CPU.

47. How does virtualization help with disaster recovery within a data center?

Power is always provided.
Less energy is consumed.
Server provisioning is faster.
Hardware does not have to be identical.

Explanation: Disaster recovery is how a company goes about accessing applications, data, and the hardware that might be affected during a disaster. Virtualization provides hardware independence which means the disaster recovery site does not have to have the exact equipment as the equipment in production. Server provisioning is relevant when a server is built for the first time. Although data centers do have backup generators, the entire data center is designed for disaster recovery. One particular data center could never guarantee that the data center itself would never be without power.

48. Which two hypervisors are suitable to support virtual machines in a data center? (Choose two.)

Virtual PC
VMware Fusion
VMware ESX/ESXi
Oracle VM VirtualBox
Microsoft Hyper-V 2012

Explanation: VMware ESX/ESXi and Microsoft Hyper-V 2012 are Type 1 hypervisors that have direct access to the hardware resources. Type 1 hypervisors are more efficient than hosted architectures, and enable greater scalability, performance, and robustness. They are used to support enterprise VMs in data centers. Oracle VM VirtualBox, VMware Fusion, and Microsoft Virtual PC are host based Type 2 hypervisors.

49. A web designer accesses a company Windows 10 computer remotely. The designer often needs to simultaneously open multiple applications, such as a web page editor and a graphics editor.
