There are two basic kinds of 10G Ethernet ports:
8P8C aka RJ45
just connect to 1G 8P8C (1000BASE-T), pretty much all 10G ports are downward compatible with 1G
SFP+
You'd need to check whether 1G SFP copper modules are available and which ones are compatible. A copper modules on one side allows you to connect to an 8P8C port on the other.
If the SFP+ ...

Symmetric routing - packet takes one path towards for example google server and turn back on using the same path.
Asymmetric - packet takes one path towards for example google server and return back using different path.

This is successful. Your traceroute got to the destination 129.97.208.23 and you got an error message from that destination. Normally the error message for traceroute is ICMP destination port unreachable for the high UDP port that traceroute used. Another common case for public websites is that the final hop does not respond to the the icmp at all (...

As infra has laid out so picturesquely, a fabric is a network where everything is interconnected. There is no rigid, official definition, but very often when talking about a fabric it is implied that
there is "sufficient" bandwidth between any two nodes, so that the network is never a bottleneck
there is adequate redundancy, so that the fabric cannot fail
...

I think you have an Idea about Fabric. It means clothes. Now just think how cloth is made with yarn. Everything is inter-connected.
See this Image. You will get the idea.
Network Fabric is also something like this and Network Fabric is Network Topology that we can use to transfer data through inter-connecting switches and network components.

Zero separation is possible.
TLDR Yes you can do it in plain ehternet where there is no any restriction applied.
If communication between VMs is based on IP protocol there will be no issue. Even if it plain L2 protocol there is no issue also if protocol can differentiate communication node not only by MAC address(for example IP protocol).
Because ARP (...

Zac has put a great answer together. But I wanted to add a simplified answer along the same lines.
Identical MAC, not within a single layer 2/broadcast domain.
There are probably a lot of devices out there with the same MAC address, but because the minimum required separation is at this very low level it doesn't cause issues.
Another consideration to ...

Suppose you have two NICs with the same MAC address, but not necessarily the same IP address.
You can't have that within the same link-layer segment. Identical MAC addresses will disable reliable switching/bridging.
What is the least possible separation (in terms of number of switches, routers, different IP subnets etc.) needed that would still allow ...

Typically, a TCP responder (here: your SIEM Syslog Server) will send a TCP-RST as a response to a TCP-SYN that tried to reach a (destination) port that was not in LISTENING state.
In other words: "Port not open".
You may want to check if the intended receiving system is actually configured to accept syslog messages on TCP (most often, Syslog runs on UDP/...
