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

Answers Explanation & Hints:

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.

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

Answers Explanation & Hints:

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.

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

Answers Explanation & Hints:

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.

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.

Answers Explanation & Hints:

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.

Place the six stages of the troubleshooting process in the correct order.

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.

Answers Explanation & Hints:

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.
