Which statement Is correct about the SLE dashboard?
- A . SLEs are displayed as a percentag e of success and classifiers are displayed as a percentage of failure.
- B . SLEs are displayed as a percentage of failure and classifiers are displayed as a percentage of success.
- C . Both SLEs and classifiers are displayed as a percentage of success.
- D . Both SLEs and classifiers are displayed as a percentage of failure.
C
Explanation:
Service Level Expectations (SLEs): In Mist’s SLE dashboard, SLEs are shown as a percentage of success. This indicates how well the network is meeting the predefined performance metrics, such as throughput, capacity, and coverage (CertsHero).
Classifiers: Classifiers, which help in diagnosing issues by breaking down SLEs into specific causes, are also displayed as a percentage of success. This unified view aids in quickly identifying areas that need improvement and ensures consistent monitoring (CertsHero).

You are the network administrator for your company. The network consists of a single Active Directory domain with five domain controllers that run Windows Server, Enterprise Edition. You are updating the public key infrastructure (PKI) for your company. Issuing Certification Authorities (CAs) have been provided certificates with a validity period of five years. Certificates are issued to enable network users to encrypt files on their computers.
Basic EFS certificates have been issued and have been configured with the default validity period. You want to configure all new EFS certificates so that they are valid for up to three years.
What should you do?
Each correct answer presents part of the solution. (Choose all that apply.)
- A . Duplicate and rename the Basic EFS certificate template.
- B . Open the Basic EFS certificate template Properties dialog box.
- C . Select the General tab and edit the validity period.
- D . Select the General tab and edit the renewal period.
- E . Select the Security tab and change the permission for the Administrators group to Enroll.
In which two Mist configuration levels would you create labels? (Choose two.)
- A . site
- B . organization
- C . switch
- D . location
How does Mist determine the location of clients in an Indoor setting?
- A . triangulation
- B . GPS
- C . probability surface
- D . trilateration
D
Explanation:
Understanding Location Determination in Mist:
Mist uses advanced methods to determine the location of clients in an indoor setting.
Possible Methods:
Triangulation: Uses angles to determine position, but not typically used by Mist.
GPS: Not feasible indoors due to signal limitations.
Probability Surface: Involves calculating the probability of a client’s location, but not the primary method used.
Trilateration: Uses the distance from multiple known points to determine the exact location.
Mist’s Method:
Mist primarily uses trilateration to determine the location of clients by measuring the distance from at least three access points.
Which two statements correctly describe Mist organizations and sites? (Choose wo.)
- A . A site is contained within an organization.
- B . Multiple sites may be contained within a single organization.
- C . An organization is contained within a site.
- D . Multiple organizations may be contained within a single site.
A B
Explanation:
In the Mist architecture, an organization is a higher-level entity that can contain multiple sites.
You are troubleshooting a wireless client’s issue and you suspect It Is related to DHCP latency.
In this scenario, which SLE should you review in the Mist Ul?
- A . Capacity
- B . Time to Connect
- C . Throughput
- D . Coverage
B
Explanation:
Identify the Problem: Suspected issue related to DHCP latency while troubleshooting a wireless
client.
Understanding SLEs:
Capacity: Related to the number of clients and bandwidth.
Time to Connect: Measures the time taken for clients to connect, including DHCP latency.
Throughput: Measures the data transfer rate.
Coverage: Measures the signal strength and coverage area.
Selecting the Appropriate SLE:
Time to Connect is the relevant SLE as it includes metrics on DHCP latency, which affects the connection time.
Review the SLE:
Analyze the Time to Connect SLE to identify any latency issues with DHCP.
