You are configuring a new server for a customer. The customer has given you the following information regarding their environment: 2 processors with 22 cores 256GB RAM 600GB of usable internal…

Question

Options

• ADoes the application require a large memory footprint
• BDoes the application require RoCE capable adapters?
• CIs the application workload sensitive to I/O latency?
• DWill a Fibre Channel card be required?

Explanation

I/O latency sensitivity is the critical factor for internal storage selection because different storage technologies (HDD, SSD, NVMe) vary dramatically in their latency profiles - a latency-sensitive workload like a database or real-time transaction system demands NVMe or SAS SSD, while a bulk-data workload can use slower, cheaper SATA or SAS HDDs. Without knowing whether the application is I/O-sensitive, you cannot justify the right storage tier for the 600GB of internal space.

Why the distractors are wrong:

• A (memory footprint): RAM requirements are already answered - 256GB is specified. Memory size doesn't determine which storage type to use.
• B (RoCE adapters): RDMA over Converged Ethernet relates to network fabric for high-speed clustering (e.g., HPC or storage networking), not internal storage selection.
• D (Fibre Channel): FC is an external SAN connectivity option. The question is specifically about internal storage configuration, making FC irrelevant here.

Memory tip: Think "I/O = Input/Output = storage speed." When the question asks about internal storage type, the deciding factor is almost always workload I/O behavior - not memory, not network cards. If the app can't tolerate delays reading/writing data, you need fast storage.
