Medium Backup Strategy Backups Troubleshooting	Solve
As a DBA, you receive an alert notifying you that the production database has gone offline due to a severe issue. Fortunately, you have a proper backup strategy in place. The backups are performed as follows: 1. Full database backup every Sunday at 2:00 AM. 2. Differential backup every day at 2:00 AM, except Sunday. 3. Transaction log backup every hour. Today is Wednesday, and the failure occurred at 10:15 AM. You have the following backup files available: 1. Full backup: Full_Backup_Sun.bak taken on Sunday 2:00 AM. 2. Differential backups: Diff_Backup_Mon.bak, Diff_Backup_Tue.bak, Diff_Backup_Wed.bak taken at 2:00 AM on their respective days. 3. Transaction log backups: Hourly backups from Sunday 3:00 AM until Wednesday 10:00 AM, like TLog_Backup_Wed_09.bak, TLog_Backup_Wed_10.bak. Given the RPO (Recovery Point Objective) of 15 minutes, which of the following sequences of restore operations would ensure minimal data loss? A: Full_Backup_Sun.bak, Diff_Backup_Wed.bak, then all Transaction Log backups from Wednesday. B: Full_Backup_Sun.bak, Diff_Backup_Tue.bak, then all Transaction Log backups from Tuesday and Wednesday. C: Full_Backup_Sun.bak, Diff_Backup_Wed.bak, then Transaction Log backups from Wednesday 2:00 AM to 10:00 AM. D: Full_Backup_Sun.bak, then all Transaction Log backups from Sunday to Wednesday 10:00 AM.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment MS SQL Server 2005/2008 beoordelingstest in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

What topics are covered in the MS SQL Server Online Test?

SQL Querying
SQL -vragen omvat schrijven en uitvoeren Query's om gegevens op te halen, te manipuleren en te beheren die zijn opgeslagen in een SQL -database. Het is een essentiële vaardigheid om in de test te meten, omdat het het vermogen van een kandidaat bepaalt om informatie efficiënt te extraheren uit databases met behulp van gestructureerde querytaal.
Databasebeheer
Databasebeheer omvat het beheer, organiseren, organiseren, en het beheersen van de verschillende aspecten van een databasesysteem. Deze vaardigheid wordt gemeten in de test om de kennis en competentie van kandidaten te evalueren bij het beheren van databasecomponenten zoals gegevensopslag, gebruikerstoegangsmanagement, back -up- en herstelprocedures en prestatie -optimalisatie.
indexen </h4> <p > Indexen zijn gegevensstructuren die de snelheid van het ophalen van gegevens op databasetabellen verbeteren. Het meten van het begrip van een kandidaat van indexen in de test helpt bij het beoordelen van hun vermogen om efficiënte databasestructuren te ontwerpen en te implementeren, waardoor snellere gegevenstoegang voor toepassingen wordt gewaarborgd. </p> <h4> Normalisatie
Normalisatie is het proces van het organiseren van gegevens In een database om duplicatie te verminderen, de gegevensintegriteit te verhogen en de algehele efficiëntie te verbeteren. Deze vaardigheid wordt in de test gemeten om de kennis van kandidaten van databaseontwerpprincipes en hun vermogen om goed gestructureerde, genormaliseerde databases te maken te evalueren.
databasebeperkingen
databasebeperkingen zijn regels en beperkingen Toegepast op gegevens in een database om gegevensintegriteit en consistentie te behouden. Het meten van deze vaardigheid in de test helpt bij het beoordelen van de bekendheid van kandidaten met verschillende soorten beperkingen en hun vermogen om gegevensvalidatieregels binnen een database af te dwingen.
Transacties
Transacties zijn sets van databasebewerkingen die dat van databasebewerkingen zijn. worden behandeld als een enkele werkeenheid, waardoor gegevensconsistentie en integriteit worden gewaarborgd. Deze vaardigheid wordt in de test gemeten om het begrip van kandidaten van transactiebeheersingconcepten te evalueren, zoals het waarborgen van atomiciteit, consistentie, isolatie en duurzaamheid in database -bewerkingen.
opgeslagen procedures
opgeslagen procedures zijn vooraf gecompileerde sets van SQL -instructies opgeslagen in een database en uitgevoerd als een enkele eenheid. Deze vaardigheid wordt in de test gemeten om de vaardigheid van kandidaten bij het maken, beheren en uitvoeren van opgeslagen procedures voor efficiënte en veilige databasebewerkingen te beoordelen.
triggers
triggers zijn database -objecten die automatisch zijn die automatisch zijn uitgevoerd in reactie op specifieke gebeurtenissen voor gegevensmanipulatie. Het meten van deze vaardigheid in de test helpt bij het evalueren van de kennis en het vermogen van kandidaten om triggers te maken om bedrijfsregels af te dwingen, gegevensintegriteit te behouden en taken in een databasesysteem te automatiseren. Virtuele tabellen gegenereerd door query's die gegevenstoegang vereenvoudigen door een logische weergave van de onderliggende databasetabellen te bieden. Deze vaardigheid wordt in de test gemeten om het begrip van de kandidaten te beoordelen in het creëren en gebruiken van weergaven om complexe vragen te vereenvoudigen, de prestaties te verbeteren en de gegevensbeveiliging te verbeteren.

Niet-googelbare vragen
IP Proctoring
Web Proctoring
Webcam Proctoring

Hoe interpreteer ik testscores?

Het belangrijkste om in gedachten te houden is dat een beoordeling een eliminatietool is, geen selectietool. Een vaardighedenbeoordeling is geoptimaliseerd om u te helpen kandidaten te elimineren die niet technisch gekwalificeerd zijn voor de rol, het is niet geoptimaliseerd om u te helpen de beste kandidaat voor de rol te vinden. Dus de ideale manier om een beoordeling te gebruiken is om een drempelscore te bepalen (meestal 55%, wij helpen u benchmark) en alle kandidaten uit te nodigen die boven de drempel scoren voor de volgende interviewrondes.

Voor welk ervaringsniveau kan ik deze test gebruiken?

Elke ADAFACE -beoordeling is aangepast aan uw functiebeschrijving/ ideale kandidaatpersonage (onze experts van het onderwerp zullen de juiste vragen kiezen voor uw beoordeling uit onze bibliotheek van 10000+ vragen). Deze beoordeling kan worden aangepast voor elk ervaringsniveau.

Krijgt elke kandidaat dezelfde vragen?

Ja, het maakt het veel gemakkelijker voor u om kandidaten te vergelijken. Opties voor MCQ -vragen en de volgorde van vragen worden gerandomiseerd. We hebben anti-cheating/proctoring functies. In ons bedrijfsplan hebben we ook de optie om meerdere versies van dezelfde beoordeling te maken met vragen over vergelijkbare moeilijkheidsniveaus.
