CV0-004 Exam Dumps : CompTIA Cloud+ (V4)

Remote replication for failover is the data protection strategy that should be used to back up on-premises data to the cloud for an earthquake-prone location. It provides real-time or near-real-time copying of data to a remote location, which can be quickly activated in case the primary site fails.

Disaster recovery strategies, including remote replication for failover, are part of the cloud-based data protection methods covered in the CompTIA Cloud+ certification.

Comprehensive and Detailed 150 to 200 words of Explanation from CompTIA Cloud CV0-004 Study guide and objectives:

The most likely cause is a Layer 2 segmentation mismatch between the VM host’s storage uplink and the SAN’s iSCSI network. In the provided switch configuration, the VM host storage uplink on GigabitEthernet 1/0/2 is configured as an access port in VLAN 24, while the SAN iSCSI controller ports (GigabitEthernet 1/0/6 and 1/0/7) are placed in VLAN 25. If the VM host’s iSCSI initiator interface is connected to Gi1/0/2, it will be in VLAN 24 and therefore cannot reach iSCSI targets in VLAN 25—preventing discovery entirely (no iSCSI SendTargets responses, no target login).

This aligns with Cloud+ (CV0-004) networking objectives emphasizing network segmentation, correct VLAN placement, and hybrid/virtualized storage connectivity. While jumbo frames (MTU 9000+) can improve iSCSI efficiency, MTU mismatch typically impacts performance or causes large-payload issues—not basic target discovery. Correcting Gi1/0/2 to access VLAN 25 restores Layer 2 adjacency to the iSCSI targets.

Given that the WAF was hardened without changing any ports and all protected applications continued to function as expected, it is most likely that the engineer blocked all traffic originating outside of North America, which is the company's operating region.
