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.

Signature-based detectionis the most common method of malware detection. It works by comparing files and data to a database of known malware signatures:

Fast and efficient for known threats.

Updated regularly by security vendors.

Reputation-based:Looks at the trustworthiness of files/domains.

Behavioral:Monitors actions and identifies suspicious patterns.

Heuristic:Detects new malware based on file behaviors and patterns, useful for unknown threats.

In continuous data protection (CDP), journal space stores all the changes made to data over time. The amount of journal space determines the retention window, i.e., how far back in time data can be recovered. A larger journal allows for a longer recovery window.

Amount of space the source and replica volumes require:Relates to storage capacity, not recovery time.

Length of time required to recover the data:Depends on system performance and data size.

Amount of data that can be restored to a specific point:Depends on the changes captured in the journal.

Total operational hours required: 12 hours/day × 5 days = 60 hours

Total downtime during required hours:

Monday: 2 hours

Wednesday: 1 hour (only 5 PM to 6 PM counts)

NAS systemsare purpose-built to handle file sharing and provide:

Centralized file accessfor multiple clients.

Optimized file sharingthrough dedicated hardware and software.

Efficient managementwith file-level protocols (NFS, CIFS/SMB).

FC protocols(Option B) are for block storage, not NAS.

Object ID(Option C) relates to object storage, not NAS.

Speed (Option D): While NAS can offer good speed, its main advantage is shared file access.

Intelligent storage systems incorporate advanced features like automated tiering, deduplication, and compression. These features enable efficient storage utilization and optimized management by automating data placement and reducing manual intervention.

Option A: While intelligent systems may facilitate cloud integration, they do not guarantee cost-free migration.

Option B: Data reduction features help, but the primary advantage is broader efficiency and optimization.

Option C: Creating silos increases complexity; intelligent systems aim to unify and simplify storage management.

Astub fileis a small placeholder file that remains on primary storage after data has been archived or moved to secondary storage.

Itcontains a pointer or addressof the archived data’s location.

When accessed, the data is transparently retrieved from the archive.

Address of the source fileand other options do not accurately describe a stub file’s purpose.

AnIDPS (Intrusion Detection and Prevention System)monitors network traffic and system activities for signs of malicious activity and policy violations. It canidentify and blocksecurity threats in real-time.

Antivirus software:Focuses on detecting/removing malware, not broader vulnerabilities.

Password encryption:Secures credentials but does not identify vulnerabilities.

IAM:Manages access but does not detect attacks.

In traditional storage provisioning, the RAID configuration significantly impacts the storage system's characteristics:

RAID Level: Determines data redundancy and fault tolerance. For example, RAID 1 mirrors data, providing high availability, while RAID 5 uses parity, balancing performance and redundancy.

Number of Drives: Affects both capacity and performance. More drives can increase total storage capacity and improve performance through parallel data access.

Make of Drives: While drive quality matters, it's less influential than RAID configuration in determining overall system characteristics.

Capacity of Drives: Impacts total storage size but doesn't directly influence performance or availability as significantly as RAID level and drive count.
