You need đồ sộ enable hosts on your network đồ sộ find the IP address of logical names, such as srv1.myserver.com. Which device should you use?

In this scenario, you would most likely need đồ sộ configure the forward lookup zone. The forward lookup zone matches the hostname đồ sộ the IP address.
You wouldn't need đồ sộ configure the reverse lookup zone since you can access the intranet site using the IP address. A reverse lookup zone matches the IP address đồ sộ the hostname.
Dynamic DNS (DDNS) enables clients or the DHCP server đồ sộ update records in the zone database automatically. This occurs whenever an IP address lease is created or renewed. This is not necessary in this scenario.
The CNAME record provides alternate names (or aliases) đồ sộ hosts that already have a host record. Using a single A record with multiple CNAME records means that when the IP address changes, only the A record needs đồ sộ be modified. This is not necessary in this scenario.

If dynamic DNS is in use, which of the following events causes a dynamic update of the host records? (Select two.)

Enter the ipconfig /registerdns command on a workstation.
Renew the DHCP server's IP address lease.

Which of the following services automatically creates and deletes host records when an IP address lease is created or released?

You are the network administrator for a small consulting firm. The firm has recently rolled out a new intranet site, and you are responsible for configuring the DNS.
You are able đồ sộ connect đồ sộ the intranet site by using the IP address, but you cannot connect when you use the hostname.
Which of the following vì thế you need đồ sộ configure sánh that the site can be accessed with the hostname?

In this scenario, you would most likely need đồ sộ configure the forward lookup zone. The forward lookup zone matches the hostname đồ sộ the IP address.
You wouldn't need đồ sộ configure the reverse lookup zone since you can access the intranet site using the IP address. A reverse lookup zone matches the IP address đồ sộ the hostname.

Which of the following is the first place a computer looks at during the name resolution process?

You want đồ sộ implement a protocol on your network that allows computers đồ sộ find a host's IP address from a logical name. Which protocol should you implement?

Listed below are several DNS record types. Match each record type on the left with its function on the right.

What is the process of a DNS server asking other DNS servers đồ sộ perform name resolution known as?
