350-601 Cisco Exam Lab Questions

The correct answer is C. standby supervisor.

From the exhibit, the command output clearly shows:

Module 6 SUP Yes disruptive Module Upgradable and later confirms:

Module 6 EPLD upgrade is successful and 6 SUP Success.

This indicates that the EPLD upgrade was performed on a Supervisor (SUP) module, specifically module 6. In Cisco MDS 9700 architecture, supervisor modules operate in a redundant pair (active and standby). When EPLD upgrades are performed, Cisco best practice and system behavior typically upgrade the standby supervisor first, because it allows the system to maintain control-plane continuity and minimizes disruption.

The output does not mention PSU, fan, or fabric modules, eliminating options A, B, and D. The explicit reference to SUP confirms that the upgrade applies to a supervisor module.

Thus, based on the module type shown in the output and standard Cisco upgrade behavior, the EPLD upgrade is applied to the standby supervisor, making C the correct answer.

The correct answer is C. Ansible because it is the one option that matches all three stated requirements at the same time. Official Ansible documentation describes Ansible as an agentless automation tool installed on a control node, and states that it manages remote systems over SSH without requiring additional daemons or software on the managed nodes. Ansible documentation also states that its playbooks are written in YAML, which is intended to be easier for humans to read and write, making it a strong fit for teams with limited scripting experience.

The other options do not fit as cleanly. Chef can use SSH in agentless mode, but Chef’s core model is based on Chef Infra Client, which is an agent, and its automation logic is built around recipes rather than simple declarative YAML playbooks. Puppet supports declarative configuration and can use SSH through Bolt, but Puppet commonly relies on installed agents in standard deployments. PowerShell is primarily a scripting language, not the best match for the requirement for an easy-to-read declarative orchestration tool. Therefore, Ansible is the best and verified choice.

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.
