System Administrator 2026 — Test 17

Correct Answer: B. B. False
Explanation: An SNMP engine is defined with explicit subsystems that include dispatch and message-processing functions. It manages all three versions of SNMP to coexist in a management entity. This formalizes the various messages that have been in use in the earlier versions.

Correct Answer: D. D. By reordering and time delaying of message streams
Explanation: SNMPv3 has enhanced security features as compared to SNMPv1 and SNMPv2. The configuration can be set remotely with secured communication that protects against the modification of information and masquerades by using encryption schemes. It also tries to ensure against malicious modification of messages by reordering and time delaying of message streams.

Correct Answer: B. B. False
Explanation: In a dispatch subsystem of SNMP architecture, there is only one dispatcher in an SNMP engine and it can handle multiple versions of SNMP messages.

Correct Answer: C. C. Authorization
Explanation: There are three subsystems in SNMPv3 architecture. They are Dispatcher Subsystem, Message Processing Subsystem and Security and Access Control Subsystem. The access control subsystem provides access to authorization service.

Correct Answer: A. A. It converts the xml pdu to snmp pdu
Explanation: An SNMP security management architecture that is policy-based is composed of several components. XML interpreter converts the XML PDU to SNMP PDU. It then transfers these SNMP PDUs to other applications.

Correct Answer: B. B. Command generator
Explanation: SNMPv3 formally defines five types of applications. They are command generator, command responder, notification originator, notification receiver, and proxy forwarder. A command generator application is used to generate get-request, get-next-request, get-bulk, and set-request messages.

Correct Answer: B. B. Configuration
Explanation: SNPv1 provides active management tasks. It sets the foundation for performing fault and configuration management. In configuration management, network operations are controlled whereas in fault management network problems are solved.

Correct Answer: C. C. Statistical
Explanation: The characterization of the performance of a computer network is statistical in nature. This led to the logical step of measuring the statistics of important parameters in the network from the NOC and the development of remote monitoring (RMON) specifications.

Correct Answer: A. A. Passive
Explanation: SNMP messages going across the network between a manager and an agent is examined. This is accomplished by using a tool that “sniffs” every packet that is going across a local area network (LAN), opens it and analyzes it. Thus it is a passive operation.

Correct Answer: B. B. False
Explanation: In RMON, individual segments can be monitored on a continuous basis. This characteristic of RMON proves to be more advantageous. It helps in faster detection and reporting of faults to the Network Management System. It provides better control of the network.
