E sounds right, synchronized instances are key for canary deployments.
BU

Wait, D? I thought the database could still be accessed during copying?
PA

B seems a bit off, traffic shouldn't spike that much.
IO

I agree, C is also a must for compatibility!
GA
Gail

A is definitely true, schema changes can slow things down.
LE

I have a vague memory that the database isn't locked during the copy process, so I'm hesitant about option D being correct.
HO
Hobert

I practiced a question similar to this, and I think option B could be misleading; I don't recall traffic increasing significantly just because of a new instance.
TH
Thad

I'm not entirely sure, but I feel like the database needs to support all versions of the service during a canary deployment, which makes me lean towards option C.
DO
Dorthy

I remember discussing how changes to the database schema can impact performance, so I think option A might be true.

Alright, time to put on my database thinking cap. I'm leaning towards A and B being the correct answers here, but I'll double-check my understanding before submitting.

Oof, database questions are not my strong suit. I'm going to have to really focus on this one. Maybe I can eliminate a couple of the options and then make an educated guess.

Ah, this is a good one. I'm pretty confident that C is true - the database schema needs to be compatible across all service versions. But the other options have me a bit stumped.
PA

Okay, let's see here. I think A and B are both true, but I'm not sure about the other options. Gotta be careful with database schema changes and increased traffic during a canary rollout.

Hmm, this question seems to cover some tricky database concepts related to canary deployments. I'll need to think through the different options carefully.

This looks like a pretty straightforward IPSec VPN question. I think the key is remembering the two-stage process - the first stage is about establishing the identity of the peers, so the answer is probably IKE SA.
RE

Hmm, I'm not entirely sure about this one. The options cover a few different responsibilities of the Service Desk. I'll need to think through each one to determine which is the primary responsibility.
TA
Talia

I remember we discussed the importance of confidentiality during audits, so I think option C makes the most sense.
EL

I'm leaning towards picking E because it seems like all those elements together would give a complete cash picture.

E is a must, you need that second database instance to handle the traffic. Otherwise, your whole deployment could go up in flames!
PR

Without the second database instance, the deployment could be at risk of failure.
CO
Corrina

I agree, having that second database instance is crucial for handling the increased traffic.
RO

E is definitely a must for canary deployments.
JU

Haha, imagine if the database was just a goldfish bowl that they had to transfer between instances. Talk about a 'canary' deployment!
PE

E) Canary deployments require two synchronized instances of each database.
TO

Haha, that would be quite the sight to see! Like passing around a goldfish bowl.

C) The database schema must be compatible to all running versions of a service.
RE

A) Changes to the database schema can take long and reduce the database performance.
CA
Catarina

A and B are definitely true. Database schema changes and increased traffic can really impact performance. Better be prepared!
CR
Cruz

I'm not sure about D. Wouldn't the database be locked during the entire deployment process, not just while copying the data?
NU

KA

A) Changes to the database schema can take long and reduce the database performance.
AL

C and E sound like the right answers to me. Managing database changes during a canary deployment can be tricky.
VA

I agree with Mira, B and E make more sense in this scenario.
MI
