Not sure about that, seems a bit off to me.

Definitely true, I've seen it in action.

Wait, can it really send ARP queries first?
JI
Jina

I thought it was just for duplicate IPs, not DNS queries.
RO

True, that's how ARP works!
NA

I’m confused; I thought the host could only send gratuitous ARPs after it has its own IP address confirmed.
LE

I feel like I've seen a similar question before, and it was about the order of ARP requests and gratuitous ARPs. Maybe it's False?
JO

I'm not entirely sure, but I remember something about gratuitous ARPs being sent to check for duplicates after the initial ARP queries.
OT

I think the answer is True because ARP queries are typically sent before any other network activity, right?

This seems like a tricky question. I'll make sure to read it thoroughly and consider the details before making my choice.

Hmm, I'm not sure about this one. I'll need to think it through carefully before selecting an answer.

Okay, I remember now. The host can send ARP queries to find the MAC address of the DNS server, but it needs to do gratuitous ARPs to check for duplicate IPs. I'll go with True.
EV

I'm a bit confused about the difference between ARP queries and gratuitous ARPs. I'll need to review that before answering.
HU
Hui

This question seems straightforward. I think the host is allowed to send ARP queries for the local DNS server before sending gratuitous ARPs.
ST

I agree with Hana. It's important to ensure communication with the DNS server before checking for duplicate IP addresses.
EM
Emily

True, of course! The host has to find the DNS server first before it can check for duplicate IPs. That's just basic networking 101.
RO

Agreed, it's an essential step in the boot-up process.
HY

Exactly, finding the DNS server is crucial for network communication.
DA

A) True
KA

False. I think sending gratuitous ARPs to test for duplicate IP addresses should come first.

I don't know, but I bet the exam writer has a good sense of humor. They're really testing our knowledge of network protocols, not our ability to juggle.

I think it's true.
BE

A) True
HA
Hana

True. It makes sense to first query for the MAC address of the local DNS server.
AL

False. Wouldn't the host need to know the IP address of the DNS server to send an ARP query? Sounds like a chicken and egg problem to me.
GR
Grover

True, the host can send ARP queries for the MAC address of the local DNS server before checking for duplicate IPs. Why not just ask the DNS server directly?
JE
Jettie

True, it's a way to ensure there are no IP address conflicts before fully joining the network.

Yes, the host should test for duplicate IP addresses first.
