What does an assigned IP address 169.254.0.12 indicate?
- A.
The computer is configured with a static IP address.
- B.
The computer is using a dial-up modem.
- C.
The computer is being used as an Internet shared connection host.
- D.
The computer has been configured to work with a Linux system.
- E.
The computer is configured for DHCP and cannot connect to the DHCP server.
Correct Answer
E. The computer is configured for DHCP and cannot connect to the DHCP server.Explanation
The assigned IP address 169.254.0.12 indicates that the computer is configured for DHCP and cannot connect to the DHCP server. This IP address falls within the range of Automatic Private IP Addressing (APIPA), which is used when a device is unable to obtain an IP address from a DHCP server. The APIPA range is specifically reserved for this purpose, allowing devices to assign themselves a unique IP address to enable basic network connectivity even without a DHCP server.Rate this question:

Which two are examples of wireless encryption? (Select two answers)
- A.
VPN
- B.
PPP
- C.
WEP
- D.
WPA
- E.
MAC
Correct Answer(s)
C. WEP
D. WPAExplanation
WEP and WPA are both examples of wireless encryption. WEP (Wired Equivalent Privacy) is an older encryption standard that was commonly used in early Wi-Fi networks. However, it is now considered to be relatively weak and easily hackable. WPA (Wi-Fi Protected Access) is a more secure encryption protocol that was introduced as a replacement for WEP. It provides stronger encryption and improved security features, making it a better choice for securing wireless networks.Rate this question:

Which item is an example of a physical network address?
- A.
IP address
- B.
MAC address
- C.
Www.zombo.com
- D.
Correct Answer
B. MAC addressExplanation
A MAC address is an example of a physical network address because it is a unique identifier assigned to a network interface controller (NIC) by the manufacturer. It is used to identify devices within a local area network (LAN) and is embedded in the hardware of the device. Unlike an IP address, which can change and is used for routing data over a network, a MAC address remains constant and is used for communication within the immediate network. The other options, such as a website address (www.zombo.com) and an email address ([email protected]), are examples of logical network addresses that are used for communication over the internet.Rate this question:

Which are the default network settings for a Windows computer?
- A.
DHCP and configured as part of a workgroup
- B.
DHCP and configured as a part of a domain
- C.
Static IP address and configured as part of a workgroup
- D.
Static IP address and configured as part of a domain
- E.
There are no default network settings for a Windows computer
Correct Answer
A. DHCP and configured as part of a workgroupExplanation
The default network settings for a Windows computer are DHCP and configured as part of a workgroup. DHCP stands for Dynamic Host Configuration Protocol, which automatically assigns IP addresses to devices on a network. Configuring the computer as part of a workgroup means that it is not connected to a domain, but rather a smaller network of computers. This allows for easier file sharing and collaboration within the workgroup.Rate this question:

Correct Answer
B. Create a shortcut to a network locationExplanation
The term "Map Network Drive" refers to creating a shortcut to a network location. This allows the user to easily access files and folders on a remote network location as if it were a local drive on their computer. This shortcut makes it convenient to navigate and work with files stored on a network share without having to manually browse to the location every time.Rate this question:

A hierarchical structure made up of multiple domains that trust each other is called a(n) _______?
- A.
Forest
- B.
Schema
- C.
Site
- D.
Organizational Unit
- E.
Tree
Correct Answer
E. TreeExplanation
A hierarchical structure made up of multiple domains that trust each other is called a "tree." In this structure, domains are organized in a parent-child relationship, with a single root domain at the top. The tree structure allows for the efficient management and administration of multiple domains within a network. Trust relationships between domains within the tree enable users to access resources across different domains while maintaining security and control.Rate this question:

What is the standard port for HTTP?
- A.
443
- B.
80
- C.
25
- D.
143
Correct Answer
B. 80Explanation
The standard port for HTTP is 80. This is because HTTP (Hypertext Transfer Protocol) is the protocol used for transmitting web pages and other web content, and port 80 is the default port for HTTP communication. When a user enters a website's URL in their browser, the browser automatically sends an HTTP request to the server on port 80, and the server responds with the requested web page.Rate this question:

Correct Answer
B. 443Explanation
The standard port for HTTPS is 443. HTTPS is the secure version of HTTP, which is the protocol used for transmitting data over the internet. The use of port 443 ensures that the communication between the client and the server is encrypted and secure. This port is commonly used for secure online transactions, such as online banking or shopping, where the protection of sensitive information is crucial.Rate this question:

Correct Answer
B. Verify and recreate the IssueExplanation
The first step to take in this situation is to verify and recreate the issue. This involves investigating and confirming the problem reported by the users, as well as trying to replicate the issue to understand its cause. By doing this, you can gather more information about the problem and potentially identify any patterns or common factors that may be contributing to the issue. This step is crucial in troubleshooting and resolving the problem effectively.Rate this question:

We're installing a new phone system in our main location, and the phone system technician asks you for the network details for how to connect it to the phone systems in the other locations. For redundancy purposes, we have two internet connections coming into the building, one with a VPN connection to other sites, and one with an MPLS connection to the other sites. Since phone traffic is highly susceptible to latency and bandwidth issues, you direct the technician to send the voice traffic over the VPN connection.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The explanation for the answer "False" is that the technician should be directed to send the voice traffic over the MPLS connection, not the VPN connection. Phone traffic is highly sensitive to latency and bandwidth issues, and MPLS connections are typically more reliable and provide better quality of service for voice traffic compared to VPN connections. Therefore, directing the technician to use the MPLS connection would be the appropriate choice for ensuring optimal voice quality.Rate this question:

- B.
When you rename the root domain server you will simply rename the child domain also
- C.
When you rename the root domain server you will lose the entire network orphaning the child domains
- D.
When you rename the root domain server you will not need to do anything else since domain names are inherited the child domains will acquire the new domain name
Correct Answer
C. When you rename the root domain server you will lose the entire network orphaning the child domains -
