Question 1

Your business is creating its open network. The IPv4 address space used by the network is 131.107.40.0/22. The network must be set up as depicted in the ensuing exhibit.
For each segment, subnets must be configured.
Which IP addresses on the network should you assign?

Accepted Answer

Segment A: 131.107.40.0/23 Segment B: 131.107.42.0/24 Segment C: 131.107.43.0/25 Segment D: 131.107.43.128/27

Answer

This question requires careful subnetting of the given 131.107.40.0/22 IPv4 address space. The correct answer demonstrates a valid and non-overlapping allocation of subnets for each segment. It efficiently utilizes the address range by assigning 131.107.40.0/23, then 131.107.42.0/24, and further subdividing 131.107.43.0 into /25 and /27 segments, all fitting within the parent /22 block.

Question 2

A DHCP scope has to have a reservation added for a printing device.
Which two elements ought to be mentioned in the reservation? (Select two accurate answers; each one contributes to the answer.)

Accepted Answer

the IP address

Answer

A DHCP reservation ensures that a specific network device consistently receives the same IP address from the DHCP server. To create this reservation, the DHCP server requires two unique identifiers: the device's MAC (Media Access Control) address to identify it on the network, and the specific IP address that should always be assigned to that device. This is crucial for devices like printers that need stable network addresses.

Question 3

Your organization uses both IPv4 and IPv6 on computers spread across many sites. A firewall that implements symmetric NAT guards each location.
Peer-to-peer communication must be permitted between all locations.
What do need to do?

Accepted Answer

Configure the firewall to allow the use of Teredo.

Answer

Teredo is an IPv6 transition technology designed to allow IPv6-enabled hosts to communicate over an IPv4 network, even when separated by NAT devices. Since the organization uses both IPv4 and IPv6 across sites with symmetric NAT firewalls, configuring the firewall to allow Teredo is necessary. This enables peer-to-peer IPv6 communication by tunneling IPv6 packets over UDP/IPv4, effectively traversing the NAT barriers.

Question 4

A Server Core installation of Windows Server 2008 R2 is present on the two servers known as Server1 and Server2 in your network. DNS servers are set up on servers 1 and 2.
10.0.0.1 is the IP address of Server1.
10.0.0.2 is the IP address of Server2.
Contoso.com is the usual principal zone on Server 1. Zone transfers for contoso.com are permitted.
Make sure Server2 has a copy of the contoso.com zone hosted on it.
Which command ought to be entered into Server2?

Accepted Answer

dnscmd / zoneadd contoso.com /secondary 10.0.0.1

Answer

To ensure Server2 hosts a copy of the `contoso.com` zone from Server1, Server2 must be configured as a secondary DNS server for that zone. The `dnscmd /zoneadd` command is used to add a new zone, and the `/secondary` switch specifies it as a secondary zone. The IP address `10.0.0.1` is then provided as the master DNS server from which Server2 will pull the zone data.

Question 5

For the email servers on your network, you must set up a sender policy framework (SPF) record.
What kind of resource record ought to you make?

Accepted Answer

Text (TXT)

Answer

Sender Policy Framework (SPF) records are used to combat email spoofing by specifying which mail servers are authorized to send email for a particular domain. These SPF records are published in DNS as a special type of Text (TXT) resource record. Email receivers query this TXT record to verify the legitimacy of incoming mail, enhancing email security.
