CompTIA N10-009 Exam Dumps

To enable communication between VLANs, the technician must configure inter-VLAN routing. On a Layer 3 switch, this is commonly done by creating an SVI (Switched Virtual Interface) for each VLAN. An SVI provides a virtual Layer 3 interface with an IP address that acts as the default gateway for hosts in that VLAN. Once SVIs exist and routing is enabled, the switch can route traffic between VLAN subnets internally, allowing clients in different VLANs to communicate (subject to any security controls). This aligns with Network+ (N10-009) infrastructure objectives covering VLANs, Layer 2/Layer 3 switching, and the requirement for routing to cross broadcast domains.

ACLs can permit or deny inter-VLAN traffic, but they do not create the routing function by themselves. VXLAN is an overlay tunneling technology used mainly in data centers to extend Layer 2 networks over Layer 3 fabrics, not the standard solution for basic VLAN-to-VLAN connectivity on a switch. VPC is not the required configuration element for inter-VLAN routing in this context. Therefore, configuring SVIs is the correct and most direct answer.

Content filtering can be used to block or restrict access to websites and services that facilitate torrenting and other prohibited activities. By implementing content filtering, the company can comply with the ISP's cease-and-desist order and prevent users from accessing torrent sites and engaging in prohibited activities.Reference: CompTIA Network+ study materials.

The correct answer is Active-active because a stock exchange broker requires extremely high availability, minimal downtime, and near-zero data loss. According to CompTIA Network+ (N10-009) objectives under high availability and disaster recovery concepts, an active-active configuration involves multiple systems or sites operating simultaneously and sharing the workload. If one system fails, the other continues processing traffic without service interruption.

This model provides the lowest Recovery Time Objective (RTO) and Recovery Point Objective (RPO), which is critical in financial trading environments where even seconds of downtime can result in major financial loss. Active-active architectures also support load balancing, redundancy, and continuous synchronization between systems.

A warm site (Option A) contains preconfigured hardware but may require data restoration and configuration before becoming fully operational, resulting in some downtime. A full mesh (Option C) is a network topology design and does not specifically address disaster recovery at the service level. In-band (Option D) refers to management traffic sharing the production network and is unrelated to DR strategy.

Therefore, an active-active approach is the most suitable solution for mission-critical financial operations.

Changing default admin passwords is a fundamental first step in device hardening to prevent unauthorized access.

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.
