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 error in the exhibit indicates that Guest Shell cannot resolve or reach the Python package repository. Guest Shell maintains its own Linux resolver configuration, so a valid DNS nameserver must be added to /etc/resolv.conf. The installation command must then execute through the management VRF because external repository connectivity is available through that routing context. The chvrf management command places the process in the management VRF, while pip install Markdown invokes the correct Python package manager. Setting only an NX-OS name server does not necessarily populate Guest Shell’s resolver configuration. python install is not a valid package-installation command, and cloning the source repository is unnecessary when pip is available. Cisco documentation specifically directs administrators to configure Guest Shell DNS in /etc/resolv.conf and supports using pip inside Guest Shell. Cisco NX-OS Guest Shell guidance

Cisco NX-OS PowerOn Auto Provisioning uses DHCP to provide initial addressing, gateway, DNS, and boot-script location information. The switch then contacts a TFTP or HTTP server to download the Python configuration script. Therefore, the configuration script must be deployed on the TFTP server. The DHCP server supplies the script location but does not normally host or execute the script itself. Software images and final configuration files can reside on one or more file servers referenced by the Python script, so placing the image on a TFTP server may also be part of the complete design. However, the action specifically required to execute the Python-based POAP workflow is hosting the configuration script on TFTP. Cisco’s POAP requirements explicitly identify a TFTP server containing the configuration script used to automate image installation and configuration. Cisco POAP requirements
