+You can use the following Day 2 operations to manage telco core CNF clusters.
+
+Updating a telco core CNF cluster:: Updating your cluster is a critical task that ensures that bugs and potential security vulnerabilities are patched. 
+For more information, see xref:../day_2_core_cnf_clusters/updating/telco-update-welcome.adoc#telco-update-welcome[Updating a telco core CNF cluster].
+
+Troubleshooting and maintaining telco core CNF clusters:: To maintain and troubleshoot a bare-metal environment where high-bandwidth network throughput is required, see see xref:../day_2_core_cnf_clusters/troubleshooting/telco-troubleshooting-intro.adoc#telco-troubleshooting-intro[Troubleshooting and maintaining telco core CNF clusters].
+
+Observability in telco core CNF clusters:: {product-title} generates a large amount of data, such as performance metrics and logs from the platform and the workloads running on it. 
+As an administrator, you can use tools to collect and analyze the available data. 
+For more information, see xref:../day_2_core_cnf_clusters/observability/telco-observability.adoc#telco-observability[Observability in telco core CNF clusters].
+
+Security:: You can enhance security for high-bandwidth network deployments in telco environments by following key security considerations.
+For more information, see xref:../day_2_core_cnf_clusters/security/telco-security-basics.adoc#telco-security-basics[Security basics].
