Question 13

The function of traps in SNMP is to:

Accepted Answer

Send unsolicited notifications of events

Answer

Passively monitor network devices

Answer

Actively poll network devices for information

Answer

Manage software updates remotely

Question 14

Object Identifiers (OIDs) in SNMP are used to:

Accepted Answer

Identify specific MIB objects and their attributes

Answer

Create custom MIBs for specific applications

Answer

Map SNMP messages to network addresses

Answer

Encrypt SNMP data during transmission

Question 15

In SNMP, which operation is used to obtain the present value of a specific object from an agent?

Accepted Answer

GET

Answer

SET

Answer

TRAP

Answer

WALK

Question 16

How do community strings contribute to basic security in SNMP?

Accepted Answer

Community strings serve as passwords, controlling access to SNMP operations and MIB data.

Answer

Community strings encrypt SNMP messages for secure communication.

Answer

Community strings authenticate SNMP managers and ensure data integrity.

Answer

Community strings are not relevant to SNMP security, they primarily identify devices.

Question 17

In SNMP, which operation is used to fetch data from a managed device?

Accepted Answer

GET

Answer

SET

Answer

TRAP

Answer

WALK

Question 18

In SNMP, what is the key difference between a private MIB and a standard MIB?

Accepted Answer

Private MIBs are defined by specific vendors, while standard MIBs are defined by industry organizations.

Answer

Private MIBs are used for managing proprietary devices, while standard MIBs are used for managing standard network devices.

Answer

Standard MIBs are more comprehensive than private MIBs.

Question 19

In SNMP, which field of the message PDU indicates the specific SNMP operation being performed?

Accepted Answer

PDU Type

Answer

Sequence Number

Answer

Request ID

Answer

Community String

Question 20

In SNMP, how do managers obtain and handle data from managed devices?

Accepted Answer

Managers send GET requests to agents and receive responses.

Answer

Agents proactively send data to managers without requests.

Answer

Managers only receive data through traps initiated by agents.

Question 21

In SNMPv1, what is the main purpose of the Community string?

Accepted Answer

Authentication

Answer

Error reporting

Answer

Device identification

Answer

Message sequencing

Question 22

In network monitoring, how do SNMP traps differ from informs in terms of their functionality?

Accepted Answer

Traps are sent asynchronously by agents to managers, while informs require a response from the manager.

Answer

Traps are used for critical events, while informs are used for less important events.

Answer

Traps and informs are essentially the same mechanism.
