Free Practice Questions for Cisco 350-601 Exam

The correct answer is B because Cisco OSPF MD5 authentication on an interface requires two specific elements: enabling message-digest authentication and defining a message-digest key. On Cisco platforms, the correct syntax is:

ip ospf authentication message-digest

ip ospf message-digest-key < key-id > md5 < encryption-type > < password >

In this question, the engineer must use MD5 and store the password using 3DES encryption, which corresponds to encryption type 3 in Cisco syntax. Therefore, ip ospf message-digest-key 2 md5 3 P@ssw01 is the valid form. The key ID can be any matching integer on both neighbors, and here it is 2.

Option A is incorrect because authentication-key is used for simple password authentication, not MD5 message-digest authentication. Option C is incorrect because ip ospf authentication md5 is not the NX-OS/IOS syntax used here; Cisco uses authentication message-digest. Option D is invalid because authentication-key does not take md5 in that format.

So the issue is resolved only by enabling message-digest authentication and configuring the MD5 key with encryption type 3, which is exactly what B does.

The correct answer is C because it is the only option that satisfies all four requirements at the same time. Cisco UCS Manager documentation states that an All configuration backup is an XML file containing all system and logical configuration settings. Because it is XML, it is human-readable, which matches the operations team requirement. By contrast, a Full state backup is a binary snapshot, so it is not human-readable, and System configuration or Logical configuration alone do not include both sets of settings.

For the transport requirement, SCP is correct because Cisco UCS supports backup transfer over FTP, TFTP, SCP, or SFTP, and SCP runs over SSH/TCP, providing authenticated, secure file transfer before the actual data copy occurs. TFTP is not valid here because it uses UDP and does not provide secure identity verification. Although SFTP also uses SSH/TCP, option D fails because Full state is binary, and option A fails because System configuration does not include all logical settings. Therefore, the only fully correct combination is All configuration + SCP.

Uplink failover enables the Cisco VIC to move traffic from the primary vNIC path to its secondary path when communication through the primary uplink fails. Enabling this function satisfies the first requirement. The failback timeout determines how long the restored primary path must remain operational before traffic automatically returns to it. Setting this timer to a value below five minutes satisfies the recovery requirement while avoiding immediate failback to an unstable link. The default VLAN determines VLAN handling and does not provide path redundancy. Class of service controls traffic priority rather than failover behavior. VN-Tag mode affects adapter virtualization and frame tagging but does not configure primary-to-secondary vNIC recovery. Cisco’s C-Series documentation states that vNICs can fail over when communication problems occur and defines the failback timeout as the period before the primary interface resumes operation.

Cisco APIC uses REST API operations against managed-object distinguished names. Creating a new managed object, such as an ACI tenant, is performed by sending an HTTP POST request containing an XML or JSON payload to the appropriate APIC URI. The payload defines the tenant object, normally an fvTenant, and includes required attributes such as the tenant name. GET retrieves existing objects and cannot create a tenant. PATCH is generally associated with partial modification semantics but is not the standard APIC method shown for creating this managed object. PUT is also not the method used by the APIC object model for the illustrated tenant-creation operation. A successful authenticated POST causes APIC to validate the payload and commit the new tenant to the management information tree. Therefore, POST is the correct HTTP method.
