ACDP appliancesits in the data path and:

Intercepts all writesto the production volume.

Splits each write into two copies: one goes to the production volume, the other to the replica volume.

Maintains a journal for point-in-time recovery.

Option A/B/C: These are aspects of replication, but CDP’s primary function is real-time interception and splitting of writes.

Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet. It offers fundamental infrastructure services such as compute, storage, and networking, which users can provision and manage through a self-service portal. This model allows organizations to scale resources as needed and pay only for what they use.

Dell RecoverPoint is a continuous data protection (CDP) solution that uses journaling to provideany point-in-time recoveryof data. It continuously captures and replicates data changes, storing them in a journal to enable precise recovery to any required point in the past.

Dell SRDF (Symmetrix Remote Data Facility):Provides synchronous/asynchronous replication, not CDP.

Dell TimeFinder SnapVX:Creates point-in-time snapshots but doesn’t offer continuous journaling.

Dell Cloud Tier:Used for archiving older data to the cloud.

Routers are networking devices that determine the optimal path for data packets to travel across networks. They primarily operate at Layer 3 of the OSI model, known as the Network Layer. This layer is responsible for logical addressing and routing, enabling data to move between different networks.

Layer 2 (Data Link Layer):Handles physical addressing and is the primary domain of switches.

Layer 3 (Network Layer):Manages logical addressing (IP addresses) and routing; the main operational layer for routers.

Layer 4 (Transport Layer):Ensures reliable data transfer but is not the primary layer for routers.

Layer 7 (Application Layer):Interfaces with end-user applications; not relevant to routing functions.

VM cloningallows administrators to createexact copiesof a virtual machine quickly.

Saves time compared to manually configuring new VMs.

Useful for testing, development, and scaling environments.

Each clone can be independently modified after creation.

Same IP addressis typically not the case (clones get unique addresses).

Snapshotsprovide rollback points, not full VM clones.

Performancedoes not improve because of cloning itself.

In Ethernet networking, VLANs (Virtual Local Area Networks) are identified using a 12-bit VLAN ID field in the IEEE 802.1Q standard. Since 12 bits can represent 2¹² = 4096 unique values, the maximum number of VLANs that can be supported is 4096.

1024 and 2048: These values are less than the maximum and represent subsets of possible VLANs.

8192: This exceeds the 12-bit limit and is not supported by the standard.

Native NVMeis a protocol designed for direct-attached storage (DAS) environments. It allows a host to communicate with NVM storage devices (like NVMe SSDs) within the same server.

Limitation:Native NVMedoes notsupport external NVMe storage connectivity beyond the server.

To connect to external shared NVMe storage, protocols likeNVMe over Fabrics (NVMe-oF)are used.
