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

The correct choices are A and D. In Cisco UCS, when the requirement is to aggregate links between the Fabric Interconnects and the I/O modules, the chassis discovery policy must use Link Grouping Preference = Port Channel. Cisco documents that for UCS 2200 I/O modules, selecting Port Channel causes the IOM-connected server ports to be automatically added to a port channel, which is exactly what provides link aggregation across the four 10-GbE connections per I/O module.

The second required step is D, because Cisco also states that after changing the link grouping preference, the chassis must be reacknowledged so the links are rediscovered and formed into the fabric port channel. Cisco’s UCS Manager infrastructure policy documentation explicitly notes that links can be added or removed by changing the link group preference and reacknowledging the chassis.

Options B and C do not create FI-to-IOM aggregation, and E is unrelated because unified ports are FI ports for Ethernet/FCoE or Fibre Channel flexibility, not a chassis-side requirement for this aggregation task.

To establish EIGRP adjacency on Cisco NX-OS, the global configuration must match the parameters defined at the interface level. Let ' s break down why Option A is the only correct choice:

The Key Chain Name:

Looking at the interface command: ip authentication key-chain eigrp NXOS EIGRP

The first " NXOS " refers to the EIGRP instance name, and " EIGRP " (case-sensitive) is the name of the key chain.

Option A correctly defines key chain EIGRP. Options B, C, and D use lowercase or entirely different names, which would cause an authentication mismatch.

The EIGRP Instance Name:

The interface command ip router eigrp NXOS identifies the EIGRP instance as NXOS.

Option A and Option B correctly use router eigrp NXOS. Options C and D use " EIGRP " as the instance name, which contradicts the interface-level configuration.

Authentication Mode:

The interface specifies MD5: ip authentication mode eigrp NXOS md5.

While NX-OS often requires the mode to be set on the interface, including it under the router eigrp process (as seen in Option A) ensures the process is configured to handle that authentication type.
