Microsoft AZ-104 Exam Dumps, Practice Test Questions

The token remains not yet valid until its signed start time is reached, regardless of how long the expiry is extended. The clock skew remains unaddressed.

Key rotation changes which signatures are valid, but a newly signed token still fails when its start time lies ahead of Azure Storage time. It is not the timing correction.

A stored access policy can constrain a service SAS, but the future start still prevents immediate use. The server-side policy does not fix the issuer clock.

Resource scope constrains what object can be addressed, not whether transport must be HTTPS. A blob-scoped SAS can still fail the transport requirement if unrestricted.

Removing list reduces enumeration rights, but it does not determine whether the token may be sent over plaintext HTTP.

An allowed-IP constraint limits network origin, not transport encryption. HTTP remains possible from the permitted source unless the SAS protocol is HTTPS only.

A container-scoped SAS can authorize operations against other blobs in the container even without List; removing List does not preserve a one-blob deletion boundary. Keep a blob-scoped signed resource and add only its Delete permission.

Container scope plus listing would increase visibility to other objects, directly violating the requirement for single-blob confinement.

An account-scoped SAS with broad resource types and List would expand authorization beyond the single blob. Add Delete only to the existing blob-scoped service SAS to retain the vendor's narrow access.

SAS permission letters are not a mechanism for elevating above the authorizing identity. A request cannot acquire unauthorized operations merely by adding a letter.

Azure management Reader does not supply blob data write rights. Subscription resource visibility and object operations remain separate permission sets.

Start time affects token validity timing, not the permissions available to the signer. The write request would remain outside the authorization boundary.

RBAC visibility does not add stored-access-policy support to an SAS type whose signing mechanism does not use it.

SAS variants have different signing and policy support. Treating all tokens as linked service SAS would create a false revocation plan.

Redundancy choices do not define SAS policy link support or provide the required token revocation mechanism.

The se field defines the expiration time and can constrain how long a SAS remains usable. The scenario says expiry is valid, while the custom token encodes read and write in the wrong sequence. Extending lifetime does not make wr an accepted permissions ordering and would unnecessarily expand the interval during which the credential can be used.

The spr field restricts whether a signed request may use HTTPS only or both HTTPS and HTTP. It has no authority to relax the canonical ordering of the signed-permissions field, which the service validates independently. Allowing HTTP would weaken transport restrictions and would leave sp=wr malformed; the issuer must fix the permission field and recompute the signature.

The sr field selects the signed resource scope, such as a specific Blob or its container, but it does not disable permission-order validation. Switching from a Blob to a container would broaden which objects the SAS could address and violate the one-blob requirement. Keeping the invalid wr order would still prevent the token from being correctly issued and authorized.

More time does not add the create or write permission required for upload. The same operation remains unauthorized throughout the longer validity period.

Azure anonymous public access is primarily a read-oriented exception and is not a safe write authorization mechanism. It would not supply the requested scoped signed permission.

Management Reader cannot change the operations encoded in an already signed token. The client is authenticating with that SAS, whose permission bit still disallows the upload.

Versioning settings do not turn a snapshot-bound SAS into a universal blob token. The signed target and permissions still govern authorization.

SAS signature fields are integrity protected. Editing the expiration or resource reference after signing does not produce a valid signature for a different target.

Account names do not transform the SAS's signed resource binding. Renaming is not a supported way to make a snapshot signature authorize an unrelated base blob.

A SAS is generally constructed and signed by the client using key material it possesses. The Storage service does not receive a separate control-plane request for every resulting token string, so it cannot emit a CreateSasToken event per client-side generation. A request made later with the SAS is different from the local issuance act under audit.

The permissions in a client-side signed SAS alter what later requests can do, not where the SAS string was generated. Azure Storage cannot log an issuance event for a locally signed token it never receives.

A stored access policy governs later service SAS requests, but generating the signed URL can still happen outside the Storage service. Audit the signer and observed requests instead of inventing a native per-token issuance log.

A Set Container ACL write contains the complete desired set of policies, not merely the entry being updated. Omitting vendorC from the submitted list removes it along with vendorB, inadvertently invalidating vendorC-linked service SAS tokens. Preserve every intended surviving signed identifier, including vendorC, in the new ACL payload.

A service SAS is signed client-side; Azure Storage does not maintain a general central inventory of individually issued SAS URL strings for selective deletion. SAS linked to a stored access policy can be revoked by changing or removing the corresponding signed identifier on its container. Update the complete stored policy list instead.

Rotating the account key invalidates service SAS signatures made with that key across many partners, not just vendorB. It would interrupt unaffected clients and still would not exploit the requested targeted stored-policy revocation. Preserve vendorA and vendorC signed identifiers when replacing the container ACL, and remove only vendorB.

The signed services field b correctly identifies the Blob service for Get Blob. Changing it to f would scope the SAS to Azure Files instead, causing further authorization failures for Blob endpoints. The resource type, not the service code, is the missing dimension for this particular object request.

List is used for supported listing operations at service or container level; it does not convert a service/container scoped account SAS into an object scoped token. Get Blob is an object-level read operation, so a missing object resource type cannot be compensated by adding an unrelated signed permission.

A valid expiry is already established and does not distinguish service-level from object-level operations. Infinite SAS validity is not a supported solution to resource-type scoping, and unnecessarily long expiry creates additional credential exposure. The decisive field is the signed resource types.
