A blockchain operations team is using Prometheus to monitor a Hyperledger Fabric peer. They notice that the peer's block height metric has not increased for 30 minutes, while other peers in the network continue to commit blocks. Which metric or log should they examine first to diagnose the issue?

The peer's log for 'Endorsement policy failure' entries

The peer's gossip peer count metric

A DevOps engineer wants to provide a real-time dashboard for a Quorum network that shows block height, transaction pool size, peer count, and CPU/memory usage of each node. Which combination of tools is most appropriate?

A block explorer such as Etherscan for all metrics

A custom shell script that writes metrics to a text file and displays it on a web page

Prometheus for metric collection and Grafana for visualization

ELK stack (Elasticsearch, Logstash, Kibana) for metric collection and visualization

What is the primary purpose of compliance monitoring in a blockchain deployment?

To ensure the deployment adheres to relevant legal and regulatory requirements

To reduce the storage requirements of the node

To increase the transaction throughput of the network

To automatically deploy smart contracts

What is the purpose of a migration script in a smart contract deployment framework like Truffle?

To compile the smart contract source code into bytecode

To define the sequence of steps for deploying contracts to a network

To monitor the performance of deployed contracts

To create a backup of the blockchain's state

Which monitoring activity is most likely to detect a consensus anomaly in a blockchain network?

Checking the color of the node's status LED

Monitoring the node's CPU temperature

Tracking block production rate and comparing it to the expected rate

Counting the number of active users on the network
