The default gateway for a network should bean IP address within the subnet, butnot the broadcast address. In this case:

IP: 192.163.1.15

Subnet Mask: 255.255.255.0

This means thenetwork rangeis: 192.163.1.0 - 192.163.1.255

192.163.1.255 is thebroadcast addressfor this subnet, so itcannot be used as a gateway.

Hence, the device fails to communicate outside its subnet because it's trying to use abroadcast addressas its gateway.

✅The issue is clearly with thegateway configuration.

EIGRP (Enhanced Interior Gateway Routing Protocol)is a Cisco proprietary advanced distance-vector routing protocol. While it operates within an Autonomous System (AS), itrequiresthe AS number to be configured for routers to recognize each other as EIGRP neighbors.

OSPF (Open Shortest Path First)uses areas and routers must be in the same area to form adjacencies, but it doesn't require AS numbers in the same way.

FHRP (First Hop Redundancy Protocol)is not a routing protocol but a group of protocols (e.g., HSRP, VRRP) to ensure high availability at the default gateway level.

RIP (Routing Information Protocol)does not use autonomous system numbers.

When working with fiber optic cables, one common issue is that the transmit (TX) and receive (RX) fibers might be reversed. The first step in troubleshooting should be to reverse the fibers at one end to ensure they are correctly aligned (TX to RX and RX to TX). This is a simple and quick step to rule out a common issue before moving on to more complex troubleshooting.References: CompTIA Network+ study materials.

A hybrid cloud deployment model is the best choice for the CTO's requirements. It allows the organization to run key services from the on-site data center while leveraging the cloud for enterprise services. This approach provides flexibility, scalability, and cost savings, while also minimizing disruptions to users by keeping critical services local. The hybrid model integrates both private and public cloud environments, offering the benefits of both.References: CompTIA Network+ study materials and cloud computing principles.

Clientless VPNsallow users to access network resources through asecure web portal using a browser, with no VPN software needed. This is ideal for occasional access to internal resources via HTTPS.

A. Proxyis a gateway for accessing web content, not a VPN.

C. Site-to-siteVPN connects entire networks, not individual users.

D. Direct Connectusually refers to dedicated cloud connections, not VPNs.

Quality of Service (QoS): This is a feature used in networking to prioritize certain types of traffic. By configuring QoS, network administrators can allocate higher bandwidth to time-sensitive applications like VoIP, video conferencing, or critical business applications during peak usage times. This helps to reduce latency and packet loss, which are often caused by congestion.

Load Balancing (A): While load balancing is useful in distributing traffic across multiple servers or paths, it does not address congestion on a single switch.

Port Mirroring (B): This is used for monitoring network traffic for troubleshooting and diagnostics but does not alleviate congestion.

Spanning Tree Protocol (D): STP prevents switching loops in redundant network topologies, but it is not designed to handle traffic prioritization or congestion issues.
