A company is migrating its internal DNS infrastructure to support IPv6. The DNS server currently runs on an IPv4-only host. The administrator has been asked to ensure that the DNS server can resolve AAAA records for internal hosts. The company's network is dual-stack. What is the minimum configuration required on the DNS server?

Replace the DNS server's IPv4 address with an IPv6 address

Configure the DNS server to listen on both IPv4 and IPv6 addresses, but no zone changes are needed

Assign an IPv6 address to the DNS server's network interface and ensure the DNS zone contains AAAA records

Only add AAAA records to the DNS zone; the server can remain IPv4-only

A university has a single physical network for its administrative offices and student labs. The administrator wants to ensure that student lab traffic cannot reach the administrative servers, but both groups need internet access. The switch supports 802.1Q trunking. What is the most efficient way to achieve this?

Configure the administrative servers with a firewall and block all traffic from the student lab subnet

Create two VLANs, assign administrative ports to VLAN 10 and student lab ports to VLAN 20, and configure a router with subinterfaces to route between the VLANs and the internet

Assign different IP subnets to the two groups and rely on the subnet mask to prevent communication

Create two separate physical networks with separate switches and routers

Which two parts make up an IPv4 address?

Public portion and private portion

Subnet portion and broadcast portion

Network portion and host portion

A company runs a public-facing web server at IPv4 address 203.0.113.10 and an internal file server at 10.0.0.5. Employees report that typing 'files.example.com' resolves to the public web server instead of the internal file server. The internal DNS server hosts the 'example.com' zone. Which configuration change should the administrator make to fix this issue?

Change the internal DNS server's forwarder to point to the public DNS server

Disable recursion on the internal DNS server

Add an A record for 'files' in the internal DNS zone pointing to 10.0.0.5

Create a CNAME record for 'files' pointing to the web server's hostname
