Cisco 300-810 Exam Dumps & Practice Test Questions
Question No 1:
In Cisco Unity Connection, when configuring caller input options to transfer calls to an alternate contact number, administrators and users can use different interfaces to set or change the destination number. Depending on the method used to update the transfer number, the system may or may not enforce calling restrictions using the restriction table.
Which of the following accurately describes a scenario in which the restriction table is not enforced when setting the transfer number?
A. The restriction table is enforced when an administrator changes the extension number using the Cisco Unity Connection Administration interface.
B. The restriction table is bypassed when an administrator updates the extension number through the Cisco Unity Connection Administration interface.
C. The restriction table is not checked when a user modifies the extension number using a Telephone User Interface (TUI) conversation.
D. The restriction table is not checked when a user updates the extension number through the Cisco Personal Communications Assistant (PCA) web interface.
Correct Answer:
C. The restriction table is not checked when a user modifies the extension number using a Telephone User Interface (TUI) conversation.
Explanation:
In Cisco Unity Connection, restriction tables control which numbers can be dialed during call transfers or message notifications, protecting against unauthorized or costly calls. These tables ensure that only approved destinations are used when transferring calls.
When administrators modify numbers via the Cisco Unity Connection Administration interface, the system enforces the restriction tables, ensuring that no unauthorized call destinations are configured.
Users, on the other hand, can modify their settings through different interfaces:
When users update settings via the Cisco Personal Communications Assistant (PCA) web interface, the restriction table is enforced.
However, when users make changes using the Telephone User Interface (TUI), the restriction table is not checked. This can potentially create security risks, as users might set up transfers to unauthorized destinations.
To mitigate these risks, administrators should be aware of this behavior and consider limiting TUI access or implementing additional controls to monitor user-configurable settings.
Question No 2:
In an enterprise environment integrating Cisco Unified Communications Manager IM and Presence (IM&P) with Microsoft Skype for Business (formerly Lync), SIP federation is used to enable seamless communication between users on both platforms.
Considering the technical aspects and interoperability requirements of SIP federation, which of the following statements is accurate regarding this federation?
A. You can view the presence status of a federated Skype for Business user by simply adding them as a contact in Cisco Jabber.
B. The SIP Proxy service is primarily responsible for handling XMPP packets from Cisco Jabber and translating them into SIP format for interoperability.
C. The use of TLS (Transport Layer Security) for encrypted signaling is optional when setting up SIP federation between the two platforms.
D. Directory URI (e.g., [email protected]) as an IM addressing format is not supported in SIP federation between Cisco IM&P and Microsoft Skype for Business.
Correct Answer:
A. You can view the presence status of a federated Skype for Business user by simply adding them as a contact in Cisco Jabber.
Explanation:
SIP federation allows users on different platforms to communicate using the SIP (Session Initiation Protocol). In this case, Cisco Unified Communications IM and Presence (IM&P) and Microsoft Skype for Business are federated to enable real-time messaging and presence information exchange.
With SIP federation properly configured, Cisco Jabber users can add Skype for Business users as contacts and view their presence status. This seamless communication between the platforms is possible as long as SIP federation has been set up correctly, with proper DNS records, TLS certificates, and firewall configurations.
Option B is incorrect because the SIP Proxy service is responsible for managing SIP traffic, not XMPP packets. SIP is used for interoperability between the platforms, and XMPP is not involved in this context.
Option C is false because TLS (Transport Layer Security) is mandatory for encrypted signaling when establishing SIP federation between Cisco and Microsoft platforms. Both vendors require encryption to secure the communication channel.
Option D is incorrect; Directory URI (like [email protected]) is supported for IM addressing in SIP federation between Cisco IM&P and Skype for Business. This format allows for easier user identification and is standard in modern deployments.
For successful SIP federation, proper configuration, including secure signaling (TLS), is critical to ensure seamless interoperability and security.
Summary of Correct Answers:
Question 1: C
Question 2: A
Question No 3:
In the context of the Extensible Messaging and Presence Protocol (XMPP), which is widely used for real-time communication such as instant messaging and presence information, a <message> stanza is used to send messages between clients.
Which two of the following elements are valid child elements of an XMPP <message> stanza? (Select two options.)
A. <server/>
B. <error/>
C. <client/>
D. <body/>
E. <subject/>
Correct Answer:
B. <error/>
D. <body/>
Explanation:
XMPP (Extensible Messaging and Presence Protocol) defines various stanzas for communication, including the <message>, <presence>, and <iq> stanzas. The <message> stanza is specifically used to send messages between users and can contain several child elements:
<body>: This is the main content of the message. It contains the text or payload of the message that is being sent. This is the most commonly used child element of a <message> stanza.
<subject>: This optional element can be used to provide a subject or title for the message, useful for organizing or categorizing messages, particularly in chat rooms or group conversations.
<error>: This element is used to provide error information when there is an issue processing the message, such as problems with routing, format, or processing errors. This element is critical when there are failures in message handling.
The other options are incorrect:
<server> and <client> are not valid child elements of an XMPP <message> stanza. These elements do not exist in the standard XMPP message schema.
Therefore, the correct answers are <body/> and <error/>.
Question No 4:
Users are experiencing difficulties accessing their voicemail through the Voicemail tab in their Cisco Jabber client. After entering valid Cisco Unified Communications Manager (CUCM) credentials, they receive a login failure message instead of accessing voicemail services.
The Cisco Jabber client is otherwise functioning correctly for messaging and calling services. Based on this scenario, what is the most likely root cause of the voicemail login issue?
A. The associated service profile in Cisco Unified Communications Manager is not correctly configured for voicemail.
B. The users are not provisioned within the Cisco Unity Connection server.
C. The voicemail web application password is flagged as “User Must Change at Next Sign-in”.
D. The voicemail password has not been configured for the affected users.
Correct Answer:
C. The voicemail web application password is flagged as “User Must Change at Next Sign-in”.
Explanation:
In Cisco Jabber, when users try to access voicemail, they are authenticated based on their Web Application Password, which is managed in Cisco Unity Connection. If the "User Must Change at Next Sign-in" option is enabled for the user's voicemail account, they will not be able to access voicemail through Cisco Jabber until they change their password. This often causes login failures as the users may not be aware that their voicemail password needs to be updated.
Why Option C is Correct:
Option C is the most likely root cause of the issue. If the administrator has reset the voicemail password or newly provisioned a user in Unity Connection, they might have checked the box requiring the user to change their password upon the next login. Until this password change is performed, the Jabber client cannot authenticate the voicemail login, causing the failure.
Why Other Options Are Incorrect:
Option A: If the associated service profile in Cisco Unified Communications Manager (CUCM) was misconfigured for voicemail, it would likely affect all users’ voicemail access. Since other services in Jabber are working correctly, this scenario is less likely.
Option B: If users were not provisioned within the Cisco Unity Connection server, they wouldn’t have voicemail access at all, which would prevent any voicemail interaction, not just login failures.
Option D: While it's possible that the voicemail password has not been configured for users, this is uncommon in properly provisioned environments. Voicemail password configurations are typically part of the provisioning process in Unity Connection.
To resolve this issue, users should be instructed to log into the Cisco Unity Connection web interface and change their voicemail password. Once they reset their password, they will be able to access voicemail through Cisco Jabber.
Question No 5:
In an environment where Cisco IM and Presence (IM&P) is federating with external domains using XMPP (Extensible Messaging and Presence Protocol), securing the communication is critical. This is necessary for both message protection and proper authentication during federation.
Which specific certificate is used by the Cisco IM and Presence server for XMPP Server-to-Server (S2S) interdomain federation with an external XMPP domain?
A. cup
B. cup-xmpp
C. cup-xmpp-s2s
D. Tomcat
Correct Answer: C. cup-xmpp-s2s
Explanation:
Cisco IM&P uses XMPP for both internal and external communication. When the system is federated with external domains for interdomain communication, the connection is secured through Server-to-Server (S2S) federation. To ensure secure communication between federating domains, Cisco IM&P utilizes TLS certificates. The key certificate involved in S2S federation is:
cup-xmpp-s2s: This certificate is specifically designed for server-to-server XMPP communication and is used during interdomain federation. It ensures secure, encrypted, and authenticated connections between the Cisco IM&P server and external XMPP servers.
The other certificates serve different roles:
cup: This certificate is a general-purpose certificate used for Cisco Unified Presence services and is not used for federation.
cup-xmpp: This is used for client-to-server XMPP communication (i.e., communication between clients and the server), not for federation.
Tomcat: This certificate is used for web-based services like administration and REST APIs, but not for XMPP communications.
By using the cup-xmpp-s2s certificate for server-to-server communication, Cisco IM&P ensures that data exchanged between federating XMPP domains is both secure and authenticated.
Question No 6:
In an enterprise environment, two Cisco Unity Connection clusters are digitally networked using a secure HTTPS connection. This setup enables the sharing of certain data and functionalities across clusters, allowing for features like cross-cluster voicemail delivery and directory lookups, thus ensuring a seamless user experience even across geographically dispersed locations.
When configuring Digital Networking between two Unity Connection clusters, which two types of data objects are replicated between the clusters via the HTTPS-based connection? (Select two options)
A. Partitions and search spaces
B. User greetings
C. User templates and user greetings
D. Call handlers
E. Users and their corresponding mailboxes
Correct Answers:
D. Call handlers
E. Users and their corresponding mailboxes
Explanation:
Cisco Unity Connection Digital Networking enables data replication between multiple Unity Connection clusters, facilitating seamless voicemail and directory functionality across dispersed locations. This is particularly helpful in large organizations where users might be located in different administrative or geographic clusters, but still require unified voicemail services.
When Digital Networking is enabled, the following data objects are replicated between clusters:
Users and their corresponding mailboxes: This allows users to be recognized across both clusters and enables cross-cluster voicemail delivery. A user in Cluster A can send a voicemail to a user in Cluster B as if they were on the same system. The user mailboxes are also replicated to ensure that messages are routed correctly.
Call handlers: These are system components used for automated answering, call routing, and voicemail menu navigation. Replicating call handlers ensures that voicemail navigation and automated attendants work uniformly across clusters, ensuring a consistent user experience regardless of which cluster a user is in.
The following data objects are not replicated:
Partitions and search spaces: These are cluster-specific settings and are not shared across clusters. They are manually managed and configured within each cluster.
User greetings: Greetings are personalized and typically do not need to be replicated across clusters. They are set by individual users and are usually cluster-specific.
User templates: These are also not replicated, as they define user configuration and settings, which may vary from cluster to cluster.
Thus, users/mailboxes and call handlers are the two key data objects that are replicated for seamless operation in a Digital Networking setup.
Summary:
Call handlers and users/mailboxes are replicated across Unity Connection clusters for consistent voicemail and directory services.
Partitions, search spaces, and user greetings are cluster-specific and are not replicated.
Question No 7:
In Cisco Unity Connection, if you want to redirect calls made to a specific phone extension (for example, User A) to their voicemail greeting, which call routing rule should be configured?
A. Attempt Forward Forwarded Routing Rule
B. Opening Greeting Direct Routing Rule
C. Attempt Sign-In Direct Routing Rule
D. Opening Greeting Forwarded Routing Rule
Correct Answer: D
Explanation:
Cisco Unity Connection is a voicemail system that integrates with Cisco Unified Communications Manager (CUCM) to provide voicemail services. Proper call routing is essential to direct calls to the appropriate destination, whether that is another user, a voicemail greeting, or a different system. In this case, the goal is to redirect calls made to a specific user's extension (User A) to their voicemail greeting.
Let's analyze the routing rules provided:
Opening Greeting Forwarded Routing Rule:
This is the correct rule for the scenario. It is designed specifically to handle calls that are forwarded, ensuring they are routed to the voicemail system where the opening greeting will be played. When a call is forwarded to voicemail, the system uses this rule to guide the caller to leave a message, making it the best choice for redirecting calls to User A’s voicemail greeting.
Attempt Forward Forwarded Routing Rule:
This rule is used when the call is forwarded to attempt further routing or connection, rather than immediately being sent to voicemail. It would not meet the requirement of directly sending the call to voicemail, so it’s not appropriate in this case.
Opening Greeting Direct Routing Rule:
While this rule does direct calls to the opening greeting, it is typically used for direct calls to voicemail without any forwarding. Since the question involves calls being redirected, this rule would not apply because it does not handle forwarded calls effectively.
Attempt Sign-In Direct Routing Rule:
This rule is intended for scenarios where users are required to sign in to their voicemail system, not for directly routing calls to voicemail greetings. It’s not suitable for the intended purpose of immediately directing calls to voicemail.
In conclusion, the Opening Greeting Forwarded Routing Rule is the correct choice because it properly handles forwarded calls and directs them to the voicemail greeting, ensuring that callers are prompted to leave a message. This rule is designed to meet the exact needs of the scenario described.
Question No 8:
An end user submits a support ticket reporting that, before logging in to Jabber for Windows, they encounter a warning stating that a server certificate has expired.
Which two certificates should be verified on the Cisco Unified Communications Manager (CUCM) and IM and Presence (IM&P) deployment to resolve this issue? (Choose two.)
A. CAPF certificate on Cisco Unified CM
B. CUP-XMPP certificate on IM&P
C. CallManager certificate on Cisco Unified CM
D. Tomcat certificate on Cisco Unified CM
E. CUP certificate on IM&P
Correct Answer: A, B
Explanation:
In this scenario, the user is encountering a warning about an expired server certificate while trying to log in to Jabber for Windows. This typically indicates an issue with secure communication between the Jabber client and backend servers like Cisco Unified Communications Manager (CUCM) and IM and Presence (IM&P). The expiration of server certificates can prevent the client from securely connecting to the servers, leading to authentication failures or warnings.
Let's break down the relevant certificates:
CAPF certificate on Cisco Unified CM (A):
The CAPF (Certificate Authority Proxy Function) certificate is crucial for establishing secure communication between the Jabber client and CUCM. It ensures that the client trusts the server during authentication and communication. If the CAPF certificate has expired, Jabber will not be able to establish a secure connection to CUCM, and this will trigger a certificate error or warning.
CUP-XMPP certificate on IM&P (B):
The CUP-XMPP certificate is responsible for secure communication between the Jabber client and the IM&P server, which handles instant messaging and presence services via the XMPP protocol. An expired CUP-XMPP certificate would prevent Jabber from securely connecting to IM&P for presence and messaging, leading to similar certificate-related issues.
Now, let’s look at the other options:
CallManager certificate on Cisco Unified CM (C):
The CallManager certificate secures the signaling communication between CUCM and devices, but it is not typically responsible for Jabber login or presence. This certificate is more focused on voice and call routing, so it’s less likely to be directly involved in the login issue for Jabber.
Tomcat certificate on Cisco Unified CM (D):
The Tomcat certificate secures web-based applications on CUCM, such as administrative access to the system. While important for web services, it does not typically impact the Jabber client’s ability to authenticate or communicate with CUCM for messaging or presence services.
CUP certificate on IM&P (E):
The CUP certificate handles secure services on IM&P, but it’s not as relevant to Jabber login when the primary issue relates to the XMPP service. The XMPP certificate is the one that specifically manages secure communication for presence and instant messaging.
In conclusion, the CAPF certificate on Cisco Unified CM and the CUP-XMPP certificate on IM&P are the two certificates most likely to be causing the expired certificate warning in Jabber. Renewing these certificates should resolve the issue and allow the user to log in to Jabber securely.

Question No 10:
Which protocol is primarily responsible for facilitating presence and instant messaging between clients in a Cisco Unified Communications setup?
A) H.323
B) SIP
C) XMPP
D) SCCP
Correct Answer: C
Explanation:
Extensible Messaging and Presence Protocol (XMPP) is the core protocol used by Cisco Unified IM and Presence to enable instant messaging and presence updates between Cisco Jabber clients and other federated users. XMPP supports real-time communication features including chat, status sharing, and availability notifications. It is an open standard, which also allows for federation with external domains and third-party platforms that use the same protocol. While SIP is essential for call signalling and media control, XMPP is purpose-built for presence and text-based communication in collaboration environments.
