No way, I thought unicast and multicast had different FDBs!

I agree, separate MAC FDBs for each service makes more sense!
JU

Wait, are we sure about that? I thought each VPLS had its own MAC FDB.
WA

I think a single MAC FDB is shared by all VPLS services on a PE.
PO

A VPLS service definitely uses a MAC FDB.

I thought each VPLS service used separate MAC FDBs for unicast and multicast, but I’m not entirely sure if that’s the case.

I vaguely recall that a single MAC FDB is shared among all VPLS services on a PE, but I’m not completely confident about that.
XE

I practiced a similar question, and I feel like each VPLS service has its own MAC FDB, but I could be mixing it up with something else.
ER

I think I remember that a VPLS service actually does use a MAC FDB, but I'm not sure if it's shared or separate.

Hmm, this is a good test of my VPLS knowledge. I'll eliminate the options that don't sound right, then decide between the remaining choices.
MI

I'm a bit confused on this one. I'll need to review my notes on VPLS to make sure I understand how the MAC FDB is used in that context. Gotta be careful not to overthink it.
CL

I'm pretty confident I know the answer to this one. VPLS uses a separate MAC FDB for each service, that's a key characteristic of how it works.

Okay, let me see. I know VPLS is a virtual private LAN service, so the MAC FDB behavior might be different from a traditional LAN. I'll need to carefully consider each option.
BE

Hmm, this is a tricky one. I'll need to think through the differences between how MAC FDBs are used in VPLS services compared to other network setups.

A VPLS service without a MAC FDB? That's like trying to navigate a maze without breadcrumbs. Good luck with that!
NO

So, is the MAC FDB like a bouncer at a club, only letting the right traffic in? Gotta keep those party crashers out!

C: D) Each VPLS service uses a separate MAC FDBs for unicast and multicast traffic.
EL

B: Yeah, it's like the bouncer making sure only the invited guests get in.
AG

A: B) A single MAC FDB is shared by all VPLS services on a PE.
NA

D sounds a bit too complex. Separate FDBs for unicast and multicast? I'm sticking with C, it's the most straightforward option.
FL
Floyd

Haha, A is just silly. Of course a VPLS service has to use a MAC FDB, how else would it forward the traffic?
YV
Yvonne

I was leaning towards B, but I see your point. A separate MAC FDB for each VPLS service makes sense to maintain that separation.
LO
Loren
1 year ago
Yes, it's important to ensure that each VPLS service has its own MAC FDB to prevent any issues with overlapping or shared information.
SH
Sharen
1 year ago
I agree, having a separate MAC FDB for each VPLS service helps in maintaining the separation and avoiding any potential conflicts.
NA
Nadine

I think C is the correct answer. Each VPLS service should have its own MAC FDB for better isolation.
AL
Alton
1 year ago
Hmm, I think C is the correct answer. Each VPLS service needs its own MAC FDB to keep the traffic isolated, right?
KA
Kathrine
1 year ago
Yeah, it seems like both C and D could be correct depending on the specific setup.
RO
Rosendo
1 year ago
That makes sense too. So it's either C or D then.
CA
Casey
1 year ago
I think it's actually D. Each VPLS service uses separate MAC FDBs for unicast and multicast traffic.
MI
Michael
1 year ago
I agree, C is the correct answer. Each VPLS service needs its own MAC FDB.
DE
Denae

I'm not sure, but I think it might be D because of the different types of traffic.
PA

I agree with Helga, each VPLS service has a separate MAC FDB.
HE

I think the answer is C.
