System Administrator 2026 — Test 16

Correct Answer: B. B. False
Explanation: The ATM Forum has defined as management interface architecture, ATM network reference model. There are five interfaces between systems and networks, M1, M2, M3, M4 and M5. The public NMS, which manages the public network, responds to the private NMS via the M3 interface with the relevant information or takes the appropriate action requested.

Correct Answer: B. B. Asn.1
Explanation: The MIB and the structure of management of information that is required for the management of the ATM network are specified between two sets of documents defined by IETF and the ATM Forum. The structure of management information is defined using the ASN.1 syntax.

Correct Answer: A. A. Broadband network
Explanation: The broadband network has several interpretations. One of the chief characteristics of broadband service is the integration of voice, video, and data services over the same transportation medium; in other words, it is multimedia transportation networking. The broadband network and service have contributed significantly to advances in three network segments of WAN, access network. and home/customer premises equipment (CPE) network.

Correct Answer: B. B. False
Explanation: The ATM has helped bring about the merger of computer and telecommunication networks. The implementation of these concepts in a network that is made up of ATM switches achieves high-speed network that can transport all three services (voice, video, and data). The desired quality of service is provided to individual streams (unlike the current Internet) at the same time. Therefore, this network is also easily scalable.

Correct Answer: A. A. M4
Explanation: The ATM Forum has defined as management interface architecture, ATM network reference model. There are five interfaces between systems and networks, M1, M2, M3, M4 and M5. Ml and M2 are, respectively, the interfaces between private NMS and either end-user of private network. A private NMS can access its own network-related information in a public network via an M3 interface to the public NMS. M4 is the interface between a public NMS and a public network. M5 is the interface between NMSs of two service providers.

Correct Answer: A. A. Trap
Explanation: It is very necessary to report problems occurring in a network to its respective network manager. Thus SNMP Trap messages are defined as alert messages that are sent to the network manager by the agent. This helps the network manager to take necessary actions on time.

Correct Answer: C. C. It is used to retrieve snmp object variables
Explanation: In Simple Network Management Protocol (SNMP) GET operations are used for retrieving SNMP object variables. GET, GETNEXT, GETBULK etc. are some of the SNMP message PDUs used for retrieving SNMP object variables.

Correct Answer: B. B. False
Explanation: SNMP is an asynchronous type of protocol. It means that messages are sent only when a problem is reported. This is a disadvantage.

Correct Answer: A. A. Lexicographic
Explanation: Lexicographic, Numerical, Collation and Alphabetical are conventional ways of arranging alphabets or objects in an order. Thus in SNMP we use Lexicographic convention for retrieval of objects.

Correct Answer: B. B. False
Explanation: Security in SNMP is managed by defining community, and only members belonging to the same community can communicate with each other. A manager can belong to multiple communities and can manage multiple domains.
