Accenture IT Analyst Interview Questions and Answers

DNS name resolution process translates domain names to IP addresses.

• Client sends a request to DNS resolver.

• Resolver checks its cache for the IP address.

• If not found, resolver sends a request to root DNS server.

• Root server responds with the address of TLD server.

• TLD server responds with the address of authoritative DNS server.

• Authoritative server responds with the IP address.

• Resolver caches the IP address and sends it to the client.

• Client uses the IP address to connect to the ...read more

Active Directory Schema defines the structure of objects in an AD forest.

• It determines the attributes and object classes that can be used to create objects in AD.

• It is stored in the Configuration partition of the AD database.

• It can be extended to include custom attributes and object classes.

• Changes to the schema should be carefully planned and tested before implementation.

Incremental backup only backs up changes since last backup, while differential backs up changes since full backup.

• Incremental backup saves time and storage space compared to full backup.

• Differential backup requires less time to restore data compared to incremental backup.

• Example: Incremental backup of a file system only backs up files that have changed since last backup.

• Example: Differential backup of a database backs up all changes made since last full backup.

Data life cycle management is the process of managing data from creation to deletion.

• It involves organizing, storing, protecting, and disposing of data.

• It ensures data is available, accurate, and secure throughout its life cycle.

• Examples include backup and recovery, archiving, and data retention policies.

Backup process is a method of creating copies of data to protect against data loss.

• Identify critical data to be backed up

• Choose a backup method (full, incremental, differential)

• Select a backup location (on-site, off-site, cloud)

• Schedule regular backups

• Test backups to ensure data can be restored

• Monitor backup process for errors or failures

FSMO roles are specialized domain controller roles in Active Directory.

• There are 5 FSMO roles: Schema Master, Domain Naming Master, RID Master, PDC Emulator, and Infrastructure Master.

• Schema Master: responsible for maintaining and modifying the Active Directory schema.

• Domain Naming Master: responsible for adding or removing domains in the forest.

• RID Master: responsible for allocating RIDs (Relative Identifiers) to domain controllers.

• PDC Emulator: responsible for backward comp...read more
