💡 ANSWER:

“I’d look at traffic filtering and routing design first. 👀
Techniques like ACLs can block unnecessary traffic, while route summarization can reduce routing information exchanged between networks.

The goal is simple: send only the traffic and routing information that actually needs to cross the WAN.

👉 Limited bandwidth? Make every packet count. 📡🔥

💡 ANSWER:

“If there’s no matching route, the router checks whether a default route exists. 👀
If a default route is available, the packet is forwarded toward that next hop. If there’s no suitable route at all, the router drops the packet and may send an ICMP destination-unreachable message back to the source.

👉 No route? The router needs a fallback—or the packet stops there. 🚦🔥

💡 ANSWER:

“That’s where Spanning Tree Protocol (STP) comes in. 👀
STP identifies redundant paths and places some links into a blocking state, preventing Layer 2 loops. If the active path fails, STP can recalculate and bring a backup path into use.

👉 Backup links stay ready without creating a network loop. 🔄🔥

💡 ANSWER:

“The standard choice is IEEE 802.1Q, also called Dot1Q. 👀
It adds VLAN tagging information to Ethernet frames, allowing multiple VLANs to travel across the same trunk link.

Unlike proprietary trunking protocols, 802.1Q is supported across different vendors.

👉 Different vendors, same VLAN tagging standard. 🌐🔥

💡 ANSWER:

“I’d check the interface counters and error statistics first. 👀
Errors such as CRC errors, collisions, input/output errors, or packet drops can point toward a duplex mismatch, faulty hardware, or a physical-layer problem.

I’d also compare the interface status with the connected device to identify where the errors are actually occurring.

👉 When packets disappear, the interface counters often tell the real story. 🔍🔥

💡 ANSWER:

“That’s where **Dual Stack** comes in. 👀
Devices run **IPv4 and IPv6 simultaneously**, allowing communication with either protocol while the network gradually moves toward IPv6.

👉 **You don’t have to switch overnight—run both and migrate step by step.** 🌐🔥

💡 ANSWER:
“I’d use an Access Control List (ACL). 👀
An ACL can permit or deny traffic based on things like source IP, destination IP, protocol, and port number.
👉 Don’t block everything—control exactly what’s allowed. 🔐🔥

💡 ANSWER:

“Port Security can help here. 👀
You can limit how many MAC addresses are allowed on a switch port and define what happens when an unauthorized MAC appears.

👉 Control the MACs before they control your network. 🔐🔥

💡 ANSWER:

“Yes — this is called **Equal-Cost Multi-Path (ECMP)**. 👀
When multiple routes have the same cost and meet the routing protocol’s rules, the router can install multiple paths and distribute traffic across them.

👉 **Same destination, multiple equal paths, better use of the network.** ⚡🔥

💡 ANSWER:

“That’s where QoS (Quality of Service) comes in. 👀
QoS can classify and prioritize important traffic, such as voice, so it gets better treatment when the network is congested.

👉 When the network gets busy, not all traffic has to wait equally. 📞🔥
