Cisco 300-820 (CLHCT) Sample Questions:

01. An organization wants MRA users to authenticate against the corporate identity provider and remain signed in without re-entering credentials on every launch.
Which mechanism provides this?
a) Mutual TLS certificate authentication configured on each user device individually
b) SRTP key exchange negotiated during the encrypted media handshake for every user
c) SAML SSO to the IdP using OAuth tokens
d) A shared local user account defined directly on the Expressway-E edge
 
02. Endpoints configured with secure device profiles are expected to use encrypted signaling and SRTP, but they keep registering to CUCM in non-secure mode.
What is the most likely cause?
a) Expressway-E is missing a DNS zone for the secure domain
b) The cluster is not in mixed mode so no CTL establishes trust
c) The endpoints are missing a _collab-edge SRV record for the cluster
d) The traversal zone between Expressway-C and -E is currently down
 
03. Two unrelated MRA tickets arrive the same morning at Proseware. On one endpoint the client rejects the edge during sign-in; on another the edge is reached but the internal registration never completes.
Which two conditions independently explain these MRA failures?
(Choose two.)
a) The Video Mesh nodes serving that endpoint are currently offline
b) Expressway-C cannot reach the CUCM registration services from inside
c) The _sips._tcp federation record for the endpoint is absent
d) The Directory Connector sync for the endpoint has stopped
e) The Expressway-E certificate is not trusted by the endpoint
 
04. In a multi-cluster deployment at Litware, a user signs in through MRA, the edge handshake succeeds, but the device pulls the wrong configuration and lands on the wrong call-processing cluster.
Which cause best fits this behavior?
a) The user lacks a home-cluster assignment so UDS steers to the wrong cluster
b) The _collab-edge._tls record resolves to Expressway-C instead of the edge
c) The endpoint used the internal _cisco-uds._tcp record from outside the network
d) SRTP is disabled on the device security profile for that cluster
 
05. After MRA is enabled, remote Jabber clients fail the TLS connection to Expressway-E with an 'unknown CA' error. The Expressway-E is still presenting the certificate it shipped with.
What resolves the failure?
a) Enable SRTP on the secure device profile in CUCM for clients
b) Add a DNS zone on Expressway-E for the clients' domain
c) Open an extra inbound firewall pinhole to the internal Expressway-C
d) Install a CA-signed Expressway-E certificate the Jabber clients already trust
 
06. On a B2B Expressway-E, external unregistered devices are placing transit calls that route out to the PSTN. Investigation shows a search rule whose source is set to Any.
What is the underlying problem with that configuration?
a) Source Any restricts matching to configured zones so registration is irrelevant
b) Source Any also matches unregistered and unauthenticated devices beyond known zones
c) The search rule priority is set too low for its transform to apply
d) The TURN relay must be disabled to stop the transit media path
 
07. You are hardening an Expressway-E that serves both MRA and B2B against toll fraud and unnecessary exposure.
Which two actions correctly reduce the risk?
(Choose two.)
a) Replace the CA-signed edge certificate with a self-signed one to simplify trust
b) Enable a SIP ALG on the edge firewall to filter messages
c) Open inbound firewall pinholes from the DMZ to each internal CUCM
d) Apply a CPL call policy that denies unauthenticated transit calls
e) Scope search-rule sources so unregistered devices cannot match B2B routes
 
08. Cedar Valley University keeps calling on its on-premises CUCM but wants Webex app users to gain cloud calendar scheduling and a unified call history tied to that CUCM.
Which two services are required to meet both goals?
(Choose two.)
a) Hybrid Data Security deployment protecting messaging content keys
b) Hybrid Call Service via the Call Connector for history
c) A Video Mesh cascade cluster for meeting media
d) Hybrid Calendar via the Calendar Connector for cloud scheduling
e) Webex Calling with a Local Gateway instead of the CUCM
 
09. A newly deployed MRA endpoint at Tailspin Toys trusts the CA chain, yet sign-in aborts with a certificate name-mismatch against the edge.
Which SAN entry is most likely missing from the Expressway-E certificate?
a) The Control Hub cloud organization identifier value
b) The internal hostname of each CUCM node
c) The CUCM registration domain for service discovery
d) The far-end partner organization's SIP domain
 
10. Summit Rail keeps its room systems registered to on-premises CUCM but wants those devices visible in the cloud for centralized management and analytics.
Which service links the on-premises devices to the cloud without changing their registration?
a) Hybrid Call Service for cloud CUCM calling and history
b) Webex Edge for Devices management
c) Webex Edge Audio for cloud meeting dial-in
d) A Video Mesh node for local cloud meeting media
