Question 1

If you want to connect to the IPv6 internet from a server, what kind of IPv6 do you need?

Accepted Answer

Global Address

Answer

To connect to the public IPv6 Internet, a server requires a Global Unicast Address (GUA). GUAs are globally unique and routable across the entire IPv6 network, similar to public IPv4 addresses. Other IPv6 address types like Link-Local, Site-Local (deprecated), or Unique Local addresses are designed for local network communication and are not routable on the public Internet.

Question 2

Which DHCP option should the DHCP client select as the recommended NetBIOS name resolving technique?

Accepted Answer

046 WINS/NBT Node Type

Answer

DHCP option 046, 'WINS/NBT Node Type,' is used to configure how DHCP clients resolve NetBIOS names. This option specifies the NetBIOS over TCP/IP (NBT) node type (e.g., b-node, p-node, m-node, or h-node) that clients should use. Setting this option correctly ensures clients use the recommended method for NetBIOS name resolution, often leveraging WINS servers effectively.

Question 3

In the dialog box for configuring RIP properties, which of the following is a tab?

Accepted Answer

Neighbors

Answer

In the Routing and Remote Access console, when configuring Routing Information Protocol (RIP) properties, the 'Neighbors' tab is available. This tab allows administrators to manually specify RIP neighbors. This is useful for controlling routing adjacencies in specific network topologies or when automatic neighbor discovery is not feasible or desired.

Question 4

What is disabled on the node when you run a PathPing or TraceRt and the hop returns three asterisks?

Accepted Answer

ICMP

Answer

When `PathPing` or `TraceRt` returns three asterisks (***) for a hop, it signifies that the device at that hop did not respond to the Internet Control Message Protocol (ICMP) echo requests. This typically occurs because the device's firewall or security settings are configured to block ICMP traffic. By blocking ICMP, the device prevents itself from sending back the necessary ICMP Time Exceeded or Echo Reply messages.

Question 5

You are in control of a business that operates two distinct networks in various cities. You want each office, one in Newark and one in Chicago, to be able to surf the network of the other. Additionally, you want the network's users to continue having access to the internet. How ought the DNS to be set up?

Accepted Answer

Use conditional forwarding to setup the parent DNS servers for each to send queries destined for the other to the DNS servers of the other.

Answer

Conditional forwarding is the most effective DNS setup for this scenario. It allows DNS servers in each city to forward queries specifically for the other city's domain directly to that city's DNS servers. This ensures efficient resolution of internal queries between offices while general internet queries are handled separately, providing both inter-office connectivity and internet access.
