To which of the following locations would you navigate to configure a Cisco TelePresence VCS to register only
aliases that match an entry in the Allow List?
A.
Registration > Allow List
B.
Registration > Deny List
C.
Registration > Configuration
D.
Protocols > SIP > Domains
E.
Configuration > System Configuration > SIP > Profile 1 > Authentication 1
Explanation:
You would navigate to Registration > Configuration to configure a Cisco TelePresence Video Communication
Server (VCS) to register only aliases that match an entry in the Allow List. Restriction policies are used to
whitelist or blacklist endpoint aliases. If the Restriction policy setting is set to Allow List, an endpoint will be
allowed to register only if its alias matches an Allow List entry. If the Restriction policy setting is set to Deny List,
an endpoint will be allowed to register only if its alias does not match a Deny List entry.
Navigating to Registration > Allow List will allow you to add, modify, or delete entries in the Allow List, but it will
not allow you to configure the restriction policy so that Cisco VCS will register only aliases that match an entry in
the Allow List. Similarly, navigating to Registration > Deny List will allow you to add, modify, or delete entries in
the Deny List, but it will not allow you to configure the restriction policy so that Cisco VCS will prevent
registration of aliases that match an entry in the Deny List.
You should navigate to Protocols > SIP > Domains on a Cisco VCS if a domain does not exist in the list of
defined domains. If an endpoint attempts to register with a domain name that does not exist on the VCS, the
endpoint will not be allowed to register. In addition, the error message Unknown domain will appear in the event
log.
You should navigate to Configuration > System Configuration > SIP > Profile 1 > Authentication 1 on an
endpoint if the endpoint is using incorrect authentication credentials when trying to register with Cisco VCS.
When an endpoint fails to authenticate with Cisco VCS, an Authentication Failed error will appear in the Cisco
VCS event log.Cisco: Cisco TelePresence Video Communication Server, Administrator Guide: Configuring registration
