ITPEC IP April 2023 Question 15
ITPEC IP April 2023 — Question 15 of 100
Horizontal load distribution runs the same application on several peer-level computers so processing does not concentrate on one machine. Incoming work can be divided among equivalent servers, increasing capacity and often improving availability. It is horizontal because the machines have comparable roles, and load distribution because they share the same kind of work.
Answer (d)
Why not others:
- (a) divides interface and processing roles between clients and a server, a vertical arrangement
- (b) assigns different specialized functions to different servers, which is function distribution
- (c) uses branch-level computers and a higher-level headquarters computer, forming a vertical hierarchy
Key rule: Same role across peers means horizontal load distribution; different roles mean function distribution, and hierarchical levels mean vertical distribution.
