On Core-SW01, the ports are configured with LACP (mode active) for link aggregation. On Core-SW02, the ports are configured as independent trunks, not as part of an LACP group. Because of this mismatch, LACP cannot form the bundle, and the aggregated ports on SW01 will go into a suspended state.
A). CRC errors suggest cabling or signal integrity issues, not config mismatch.
B). Error disabled occurs when a violation (like BPDU guard or port security) disables the port, not LACP mismatch.
C). Administratively down indicates a shutdown command, not the case here.

* Definition of Fiber Connector Types:
* LC (Lucent Connector):A small form-factor fiber optic connector with a push-pull latching mechanism, commonly used for high-density applications.
* SC (Subscriber Connector or Standard Connector):A larger form-factor connector with a push-pull latching mechanism, often used in datacom and telecom applications.
* ST (Straight Tip):A bayonet-style connector, typically used in multimode fiber optic networks.
* MPO (Multi-fiber Push On):A connector designed to support multiple fibers (typically 12 or 24 fibers), used in high-density cabling environments.
* Common Usage:
* LC Connectors:Due to their small size, LC connectors are widely used in network interface cards (NICs) and high-density environments such as data centers. They allow for more connections in a smaller space compared to SC and ST connectors.
* SC and ST Connectors:These are larger and more commonly used in patch panels and older fiber installations but are less suitable for high-density applications.
* MPO Connectors:Primarily used for trunk cables in data centers and high-density applications but not typically on individual network interface cards.
* Selection Criteria:
* The small form-factor and high-density capabilities of LC connectors make them the preferred choice for network interface cards, where space and connection density are critical considerations.

If the business shares or duplicates the ISP-assigned public IP address, routing instability and conflicts will occur. Pinging a public IP like 8.8.8.8 may work (since ICMP can bypass certain conflicts), but browsing websites (which requires stable sessions and return traffic) will fail intermittently.
A). If the default gateway were incorrect, no external connectivity would work at all.
B). VLAN mismatch is an internal issue, not affecting ISP routing.
C). Subnet mask misconfiguration would prevent consistent routing but usually blocks ping too.

TLS (Transport Layer Security)is the protocol that providesencryption in transit for HTTPS. It ensures data is encrypted between the client (browser) and the web server, protecting it from interception or tampering.
* A. SSHis used for secure terminal access, not HTTPS.
* C. SCADArefers to control systems, not encryption protocols.
* D. RADIUSis an authentication protocol, not for encrypting HTTPS traffic.

Explanation:
To validate routing between networks hosting Workstation A and File Server 2, follow these steps:
Review Routing Tables:
Check the routing tables of Router A, Router B, and Router C to identify any missing routes.
Identify Missing Routes:
Ensure that each router has routes to the networks on which Workstation A and File Server 2 are located.
Add Static Routes:
If a route is missing, add a static route to the relevant destination network via the correct interface.
Routing Table:

These configurations ensure that each router knows the correct paths to reach Workstation A and File Server
