What are two reasons for implementing a multifactor authentication solution such as Duo Security provide to an
organization? (Choose two)
Answer : A, D
Two-factor authentication adds a second layer of security to your online accounts. Verifying your identity using a
second factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they
know your password.
Note: Single sign-on (SSO) is a property of identity and access management that enables users to securely
authenticate with multiple applications and websites by logging in only once with just one set of credentials
(username and password). With SSO, the application or website that the user is trying to access relies on a
trusted third party to verify that users are who they say they are.

What is an advantage of network telemetry over SNMP pulls?
Answer : D
Network telemetry is a technology that allows network devices to push data to a collector in real time, rather than waiting for the collector to pull data from them. This improves the efficiency and accuracy of data collection, and enables the monitoring of a large number of network devices. SNMP, on the other hand, is a protocol that uses a pull model, where the collector requests data from the devices periodically. This can cause delays, gaps, and overhead in data collection, and limit the scalability of network monitoring. Therefore, network telemetry has an advantage over SNMP pulls in terms of scalability.Reference:

An engineer is configuring Cisco Umbrella and has an identity that references two different policies. Which action ensures that the policy that the identity must use takes precedence over the second one?
Answer : D
Cisco Umbrella evaluates policies from the top down and looks for a matching identity and destination. Once a match is found, Umbrella applies that policy's settings to the identity and destination and stops evaluating all other DNS policies. Therefore, to ensure that the policy that the identity must use takes precedence over the second one, the engineer should make the correct policy first in the policy order. This way, Umbrella will match the identity to the correct policy before checking the second policy. The other options are not correct because they do not guarantee that the identity will use the correct policy. Configuring the default policy to redirect the requests to the correct policy will not work if the identity matches another policy before the default one. Placing the policy with the most-specific configuration last in the policy order will not work if the identity matches a less-specific policy before the last one. Configuring only the policy with the most recently changed timestamp will not work if the identity matches an older policy before the newer one.Reference:=

In which two ways does Easy Connect help control network access when used with Cisco TrustSec? (Choose two)
Answer : C, E
Easy Connect simplifies network access control and segmentation by allowing the assignment of Security

An organization is using DHCP Snooping within their network. A user on VLAN 41 on a new switch is
complaining that an IP address is not being obtained. Which command should be configured on the switch
interface in order to provide the user with network connectivity?
Answer : D
To understand DHCP snooping we need to learn about DHCP spoofing attack first.
DHCP spoofing is a type of attack in that the attacker listens for DHCP Requests from clients and answers them with fake DHCP Response before the authorized DHCP Response comes to the clients. The fake DHCP Response often gives its IP address as the client default gateway -> all the traffic sent from the client will go through the attacker computer, the attacker becomes a ''man-in-the-middle''.
The attacker can have some ways to make sure its fake DHCP Response arrives first. In fact, if the attacker is ''closer'' than the DHCP Server then he doesn't need to do anything. Or he can DoS the DHCP Server so that it can't send the DHCP Response.
DHCP snooping can prevent DHCP spoofing attacks. DHCP snooping is a Cisco Catalyst feature that
determines which switch ports can respond to DHCP requests. Ports are identified as trusted and untrusted.
Only ports that connect to an authorized DHCP server are trusted, and allowed to send all types of DHCP
messages. All other ports on the switch are untrusted and can send only DHCP requests. If a DHCP response is seen on an untrusted port, the port is shut down.
The port connected to a DHCP server should be configured as trusted port with the ''ip dhcp snooping trust'' command. Other ports connecting to hosts are untrusted ports by default.
In this question, we need to configure the uplink to ''trust'' (under interface Gi1/0/1) as shown below.
