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 SQL Server 2005/2008 Bedömningstest 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.

Science behind Adaface tests

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the SQL Server 2005/2008 Bedömningstest from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

Hur tolkar jag testresultat?

Det främsta att tänka på är att en bedömning är ett eliminationsverktyg, inte ett urvalsverktyg. En kompetensbedömning är optimerad för att hjälpa dig att eliminera kandidater som inte är tekniskt kvalificerade för rollen, den är inte optimerad för att hjälpa dig hitta den bästa kandidaten för rollen. Så det ideala sättet att använda en bedömning är att bestämma en tröskelpoäng (vanligtvis 55%, vi hjälper dig att jämföra) och bjuda in alla kandidater som gör poäng över tröskeln för nästa intervjurundor.

Vilken erfarenhetsnivå kan jag använda detta test för?

Varje AdaFace -bedömning anpassas till din arbetsbeskrivning/ idealisk kandidatperson (våra ämnesexperter kommer att välja rätt frågor för din bedömning från vårt bibliotek med 10000+ frågor). Denna bedömning kan anpassas för alla erfarenhetsnivåer.

Får varje kandidat samma frågor?

Ja, det gör det mycket lättare för dig att jämföra kandidater. Alternativ för MCQ -frågor och ordningen på frågor randomiseras. Vi har anti-cheating/proctoring -funktioner på plats. I vår företagsplan har vi också möjlighet att skapa flera versioner av samma bedömning med frågor om liknande svårighetsnivåer.

Jag är kandidat. Kan jag prova ett träningstest?

Nej. Tyvärr stöder vi inte övningstester just nu. Du kan dock använda våra exempelfrågor för övning.

Vad är kostnaden för att använda detta test?

Du kan kolla in våra prisplaner.

Kan jag få en gratis provperiod?

Plattformen är helt självbetjänande, så här är ett sätt att gå vidare:

Du kan registrera dig gratis för att få en känsla för hur det fungerar.
Den kostnadsfria provperioden inkluderar en provbedömning (Java/JavaScript) som du hittar i din instrumentpanel när du registrerar dig. Du kan använda den för att granska kvaliteten på frågorna och kandidaternas upplevelse av ett konversationstest på Adaface.
För att granska kvaliteten på frågorna kan du också granska våra offentliga frågor för 50+ färdigheter här.
När du är övertygad om att du vill testa det med riktiga bedömningar och kandidater kan du välja en plan enligt dina krav.
