Correct Answer: 2

Explanation

Azure management groups provide a hierarchy above subscriptions and allow organizations to apply governance controls across multiple subscriptions. Policies and role assignments can be managed at the management group level and inherited by lower scopes where appropriate. Resource groups organize resources within subscriptions but do not provide the same cross-subscription governance capability. Availability zones are physical locations within a region, while storage accounts provide data storage. Management groups are therefore the appropriate architectural component for centralized governance across multiple Azure subscriptions.

Question 59

Which Azure feature can prevent accidental deletion of important resources?

1. Azure Resource Lock
2. Azure Advisor

Azure resource locks help protect important resources from accidental modification or deletion. A delete lock can prevent users from deleting a resource while still allowing permitted configuration changes, depending on the lock type. This is useful for protecting critical infrastructure from accidental administrative actions. Advisor provides recommendations, Monitor collects telemetry, and DNS manages domain resolution. Resource locks are therefore an important governance feature when architects need an additional safeguard against accidental deletion of critical Azure resources.

Question 60

Which Azure storage option provides redundancy across availability zones?

1. LRS
2. GRS
3. ZRS
4. Archive Storage

Correct Answer: 3

Explanation

Zone-redundant storage, or ZRS, replicates data synchronously across multiple availability zones within the primary Azure region. This design protects storage data against failures affecting an individual availability zone while keeping the data within the same region. LRS maintains copies within a single physical location, while GRS provides replication to a secondary region. Archive is a storage access tier rather than a redundancy option. ZRS is therefore the appropriate choice when an architecture requires storage resilience across availability zones.
