QUESTIONS AND ACCURATE

◉ What is the function of a MIB in SNMP? Answer: It is a definition
file for event translation.
◉ What does confidentiality with regard to data at rest ensure? Answer:
Data can be accessed after privileged access is granted.
◉ What should a network engineer do to prevent email delivery issues
after changing the MX record? Answer: Reduce the TTL record prior to
the MX record change.
◉ Which IP transmission type encrypts all of the transmitted data?
Answer: ESP (Encapsulating Security Payload).
◉ Which technology would likely mitigate interference with industrial
equipment in the 2.4GHz range? Answer: 5GHz frequency.
◉ What does ESP stand for in the context of IPsec? Answer:
Encapsulating Security Payload.
◉ What is the role of the TTL value in DNS records? Answer: It tells
how long the record should be cached.
,◉ What does the command 'no shutdown' do in a switch? Answer: It re-
enables the interface if it was previously disabled.
◉ What is the purpose of reducing the TTL before making DNS
changes? Answer: To ensure cached records expire quickly.
◉ What is a core principle of data security regarding data at rest?
Answer: Confidentiality.
◉ What does a MIB contain? Answer: Definitions and information
about all objects that can be managed on a network.
◉ What is the impact of a high TTL on DNS changes? Answer: It may
delay the propagation of changes.
◉ What does the absence of blinking indicator lights on a network
interface suggest? Answer: A physical layer issue, likely a shut down
port.
◉ What is the recommended practice before changing DNS records?
Answer: Reduce the TTL value to a lower value.
◉ What does ESP provide in addition to data confidentiality? Answer:
Integrity and authenticity of data.
, ◉ What is the effect of administratively shutting down a switch port?
Answer: It disables the port from passing any traffic.
◉ What should an administrator verify after making DNS changes?
Answer: Propagation using tools like dig or nslookup.
◉ What is the significance of the A record in DNS? Answer: It maps a
domain name to an IP address.
◉ What does the term 'privileged access' refer to? Answer: Access
granted to authorized individuals only.
◉ What is the role of SNMP in network management? Answer: To
manage and monitor network devices.
◉ Which two technologies can mitigate interference in the 2.4GHz
range? Answer: 5GHz frequency and non-overlapping channel.
◉ What is an ad hoc network? Answer: A temporary network created
for a specific purpose without a centralized management.
◉ What is the Recovery Point Objective (RPO)? Answer: The
maximum acceptable amount of data loss measured in time since the last
backup.
