Red Hat Certified System Administrator RHCSA Exam [EX200]

RHCSA-eksamen (EX200) er en performancebaseret test af din viden inden for områder af systemadministration, der er almindelige på en lang række miljøer og implementeringsscenarier. De færdigheder, der testes i, er grundlaget for systemadministration på tværs af alle Red Hat produkter. Med en RHCSA certificering får du bevis på, at du bestrider de grundlæggende færdigheder i systemadministration, der kræves i Red Hat Enterprise Linux-miljøer.

Denne eksamen er baseret på Red Hat® Enterprise Linux® version 8.

Eksamen kan også tages online - kontakt os for nærmere oplysninger.

Eksamensformat

Dette er en praktisk performance-baseret eksamen, hvor du skal demonstrere at du kan udføre real-world opgaver. Der er ikke adgang til internet under eksamen, og du må ikke medbringe nogen former for hjælpemidler, herunder noter, bøger eller andet materiale. På de fleste eksamener vil der dog være adgang til produktdokumentation under selve eksamen. Eksamen varer 2,5 time.

Scores og eksamensresultat

Det officielle resultat af din eksamen kommer udelukkende fra Red Hat Certification Central. Red Hat giver ikke eksaminatorer eller kursusudbydere tilladelse til at oplyse dig resultatet. Du vil typisk modtage svar inden for 3 arbejdsdage. Eksamensresultatet bliver oplyst som en samlet score.
