All N10-009 Test Inside CompTIA Questions

Elasticity is the ability of a system (often in cloud environments) to automatically scale resources up or down in real time based on demand.

A. Scalability means the ability to grow over time but not necessarily dynamically.

B. SaaS is a service model, not a resource-allocation concept.

C. Hybrid cloud is a deployment model, not a performance behavior.

MIB (Management Information Base): A MIB is a database used for managing the entities in a communication network. The MIB is used by Simple Network Management Protocol (SNMP) to translate events into a readable format, enabling network administrators to manage and monitor network devices effectively.

Function of MIB: MIBs contain definitions and information about all objects that can be managed on a network using SNMP. These objects are defined using a hierarchical namespace containing object identifiers (OIDs).

A hot site is a fully operational backup facility with hardware, network, and data synchronization already in place. It allows for immediate failover in the event of a disaster, minimizing downtime.

B. DCI (Data Center Interconnect) connects data centers but doesn’t guarantee availability unless built redundantly.

C. Direct Connect refers to a private link to cloud providers, not disaster recovery.

D. Active-passive can help with failover but may involve delay unless combined with hot site principles.

The correct answer is IP address blocks because geofencing policies typically rely on public IP address ranges associated with specific geographic regions or countries. According to CompTIA Network+ (N10-009) security objectives, geofencing is a security control used to restrict or allow traffic based on geographic location. This is commonly implemented on firewalls, VPN concentrators, or security gateways by referencing databases that map IP address blocks to countries or regions.

When configuring geofencing, administrators create access control rules that permit or deny traffic from specific country-based IP ranges. This method is effective for limiting remote access to approved geographic locations and reducing exposure to international threat sources.

MAC filtering (Option A) is used within local networks and does not function over the internet for geographic control. Administrative distance (Option B) is a routing concept that determines route preference and has no relation to access control policies. Bluetooth beacon signals (Option C) are used for proximity-based services and indoor positioning, not for country-level remote access restrictions.

Therefore, leveraging IP address blocks is the correct approach for implementing geofencing controls.
