CompTIA N10-009 Exam - Topic 3 Question 5 Discussion

Actual exam question for CompTIA's N10-009 exam

Question #: 5
Topic #: 3

A company's marketing team created a new application and would like to create a DNS record for newapplication.comptia.org that always resolves to the same address as www.comptia.org. Which of the following records should the administrator use?

ASOA

BMX

CCNAME

DNS

Show Suggested Answer

Suggested Answer: C

A CNAME (Canonical Name) record is used in DNS to alias one domain name to another. This means that newapplication.comptia.org can be made to resolve to the same IP address as www.comptia.org by creating a CNAME record pointing newapplication.comptia.org to www.comptia.org. SOA (Start of Authority) is used for DNS zone information, MX (Mail Exchange) is for mail server records, and NS (Name Server) is for specifying authoritative DNS servers.

The DNS section of the CompTIA Network+ materials describes the use of CNAME records for creating domain aliases.

I thought NS records were for delegating, not aliasing!

SOA is not the right choice here, just saying.

Wait, can you really use CNAME for that?

I feel like MX records are related to email, so they probably wouldn't work for this DNS resolution task.

I practiced a similar question where we had to point a subdomain to a main domain, and I think it was also a CNAME.

I'm not entirely sure, but I remember something about SOA records being more about zone information than actual address resolution.

I think the CNAME record is the right choice here since it allows one domain to point to another.

I'm still not 100% sure, but I think a CNAME record is the best option based on the information provided. I'll double-check my understanding before submitting the answer.

Okay, I've got it! A CNAME record is the way to go. It allows us to create an alias that points to the same IP address as the main website.

The question is asking about a DNS record, so I'm pretty sure the answer is either CNAME or NS. I'll have to think this through carefully.

I think this is a CNAME record since we want to create an alias for the new application to point to the same address as www.comptia.org.

Hmm, I'm a bit confused. Wouldn't an MX record be used for email-related services? I'm not sure if that's the right choice here.

I'm a bit confused on the "individual workflows per issue type" part. How exactly would that help meet additional requirements? I'll need to re-read the question carefully.

I bet the marketing team is just thrilled to be creating a new app. Hopefully they remembered to test it first before pointing a CNAME at it. That could get messy!

Definitely going with C. CNAME. Wouldn't want to accidentally point the new app to the wrong place, you know? Gotta keep that marketing team happy!

I think the correct answer is C. CNAME. That way the new application can use the same IP address as www.comptia.org without having to set up a separate A record.
