Q4. Refer to the exhibit.
Ephone 1 has three active calls. The first two calls were inbound calls, which the user put on hold to place a third call outbound. What will happen on ephone 1 when a fourth call arrives for extension 2001?
A. The fourth call will be delivered to ephone 1 because it only received two inbound calls, one call less than the busy- trigger-per-button setting.
B. The fourth call will be delivered to ephone 1 because the huntstop channel setting is not yet saturated.
C. The fourth call will be delivered to ephone 1 because it can handle up to five calls on each button.
D. The fourth call will be held temporarily by the lOS Software until ephone 1 disconnects one of the active calls.
E. The fourth call will not be delivered and the caller will hear a user busy tone.
Answer: E
Explanation:
Because on line maximum 4 calls can be placed when user put the call on hold is consume a channel and reach the maximum number of calls on line.
Q5. Refer to the exhibit.
Cisco Unity Connection Site A has two locations. Cisco Unity Connection Site B has one location. Which protocols connect the locations and servers together for messaging and replication?
A. 1 - SMTP
2- HTTP/HTTPS, SMTP
3- None
B. 1 - SMTP
2- SMTP
3- SMTP
C. 1 - HTTP/HTTPS, SMTP
2- HTTP/HTTPS, SMTP
3- HTTP/HTTPS, SMTP
D. 1 - HTTP/HTTPS, SMTP
2- SMTP
3- None
Answer: A
Explanation:
You can join two or more Connection servers or clusters (up to a maximum of ten) to form a well-connected network, referred to as a Connection site. The servers that are joined to the site are referred to as locations. (When a Connection cluster is configured, the cluster counts as one location in the site.) Within a site, each location uses SMTP to exchange directory synchronization information and messages directly with every other location. Each location is said to be linked to every other location in the site via an intrasite link.
When you link two Cisco Unity Connection sites with an intersite link, the gateway for each site is responsible for collecting information about all changes to the local site directory, and for polling the remote site gateway periodically to obtain information about updates to the remote site directory. The gateways use the HTTP or HTTPS protocol to exchange directory synchronization updates.

Q6. Refer to the exhibit.
lP phone 1 has MAC address of 1111.1111.1111, and lP phone 2 has MAC address of 2222.2222.2222. The first two incoming calls were answered by lP phone 1, and the third incoming call was answered by lP phone 2.
Which option describes what will happen to the fourth incoming call?
A. Both phones ring, but only lP phone 2 can answer the call.
B. Both phones ring and either phone can answer the call.
C. Both phones ring, but only lP phone 1 can answer the call.
D. Neither phone rings and the call is forwarded to 2100.
E. Neither phone rings and the call is forwarded to 2200.
Answer: D
Explanation:
lP Phone 1 & 2 both have busy-trigger-per-button configured to 3 & 2 respectively. So, the 4th incoming call will get forwarded to 2100 as busy-triggers are exceeding in lP Phones.

Q7. When a Cisco lOS gatekeeper receives an LRQ, what is the first step it will take in an attempt to resolve the destination address?
A. Check to see if the LRQ reject-unknown-prefix flag is set.
B. Check to see if the destination address matches the technology prefix.
C. Check to see if the destination address matches the hop-off technology prefix.
D. Check to see if the destination address matches the remote zone prefix.
E. Check to see if the LRQ forward-queries flag is set.
Answer: B
Explanation:
LRQ - These messages are exchanged between gatekeepers and are used for inter-zone (remote zone) calls. For example, gatekeeper A receives an ARQ from a local zone gateway requesting call admission for a remote zone device.
Gatekeeper A then sends an LRQ message to gatekeeper B. Gatekeeper B replies to the LRQ message with either a Location Confirm (LCF) or Location Reject (LRJ) message, which depends on whether it is configured to admit or reject the inter-zone call request and whether the requested resource is registered.
Q8. Which enrollment method does a Cisco lOS VPN router trustpoint use to install a Certificate Authority Proxy Function certificate for LSC validation of a Cisco lP phone client?
A. HTTP proxy server
B. certificate authority server URL
C. terminal
D. self-signed
E. registration authority
Answer: C
Explanation:
Router(config)#crypto pki trustpoint CAPF
enrollment terminal
authorization username subjectname commonname
revocation-check none
Router(config)#crypto pki authenticate CAPF
Router(config)#
Things to Note:
The enrollment method is terminal because the certificate has to be manually installed on the Router.

Q9. Which Cisco Unified Communications Manager deployment model for clustering over the lP WAN mandates a primary and a backup subscriber at the same site?
A. multisite with centralized call processing
B. multisite with distributed call processing
C. local failover
D. remote failover
E. remote failover with Cisco Unified Communications Manager Express as SRST
Answer: C
Explanation:
Clustering Over the lP WAN
You may deploy a single Unified CM cluster across multiple sites that are connected by an lP WAN with QoS features enabled. This section provides a brief overview of clustering over the WAN. For further information, refer to the chapter on Call Processing.
Clustering over the WAN can support two types of deployments:
u2022Local Failover Deployment Model
Local failover requires that you place the Unified CM subscriber and backup servers at the same site, with no WAN between them. This type of deployment is ideal for two to four sites with Unified CM.
u2022Remote Failover Deployment Model
Remote failover allows you to deploy primary and backup call processing servers split across the WAN. Using this type of deployment, you may have up to eight sites with Unified CM subscribers being backed up by Unified CM subscribers at another site.

Q10. How are queues serviced in Cisco lOS routers with the CBWFQ algorithm?
A. first-in, first-out
B. weighted round robin based on assigned bandwidth
C. strict priority based on assigned priority
D. last-in, first-out
E. weighted round robin based on assigned priority
Answer: B
Explanation:
Class Based Weighted Fair queuing is an advanced form of WFQ that supports user defined traffic classes i.e. one can define traffic classes based on match criteria like protocols, access control lists (ACLs), and input interfaces. A flow satisfying the match criteria for a class contributes the traffic for that particular defined class. A queue is allocated for each class, and the traffic belonging to that class is directed to the queue for that class.
Q11. Which two guidelines are recommended when configuring agent phones for Cisco Unified CCX agents? (Choose two.)
A. ln the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to 2.
B. ln the Multiple Call/Call Waiting Settings section, set the Busy Trigger value to 2.
C. The Unified CCX extension for the agent must be listed within the top four extensions on the device profile.
D. ln the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to at least 3.
E. Always enable SRTP when configuring an agent phone.
Answer: A, C
Explanation:
Follow these guidelines when configuring agent phones for Unified CCX agents:
Choose Device>Phone in Unified Communications Manager Administration. The Find and List Phones window is displayed.
Enter search criteria to locate a specific phone and click Find. A list of phones that match the search criteria is displayed. Click the device name of the phone to which you want to add a directory number. The Phone Configuration window is displayed.
ln the Unified Communications Manager Administration Phone Configuration web page, select the required Association lnformation (on the left) to get to the Directory Number Configuration web page. On this page, make the following changes:
ln the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to 2 (default is 4) for Cisco Unified lP Phones 7900 Series and 3 for Cisco Unified lP Phones 8961, 9951, and 9971.
ln the Multiple Call/Call Waiting Settings section, set the Busy Trigger value to 1 (default is 2).
ln the Call Forward and Call Pickup Settings section, verify that you do not forward any Unified Communications
Manager device to the Unified CCX extension of an agent.
ln the Call Forward and Call Pickup Settings section, verify that you do not configure the Unified CCX extension of an agent to forward to a Unified CCX route point.
Always disable (turn off) Secure Real-Time Transport Protocol (SRTP) when configuring a Cisco Unified Communications product. You can disable SRTP for a specified device or for the entire Unified Communications Manager:
For a specified device-Choose Device>Phone. ln the Find and List Phone page, select the required phone device. Ln the Phone Configuration page for the selected phone, scroll down to the Protocol Specific lnformation section. To turn off SRTP on the phone device, select any one of the Non Secure SCCP Profile auth by choices from the drop-down list
in SCCP Phone Security Profile or SCCP Device Security Profile field.
For the entire Unified Communications Manager cluster - Choose System>Enterprise Parameters. ln the Enterprise Parameters Configuration page, scroll down to the Securities Parameters section, to verify that the corresponding value for the Cluster Security Mode field is 0. This parameter indicates the security mode of the cluster. A value of 0 indicates that phones will register in nonsecure mode (no security).
The Unified CCX extension for the agent must be listed within the top 4 extensions on the device profile. Listing the extension from position 5 on will cause Unified CCX to fail to monitor the device, so the agent will not be able to log in.
Do not forward any Unified Communications Manager device to the Unified CCX extension of an agent.
Do not configure the Unified CCX extension of an agent to forward to a Unified CCX route point.
Do not use characters other than the numerals 0 to 9 in the Unified CCX extension of an agent.
Do not configure two lines on an agent phone with the same extension when both lines exist in different partitions.
Do not assign a Unified CCX extension to multiple devices.
Do not configure the same Unified CCX extension in more than one device or device profile. (Configuring a Unified
CCX extension in one device or device profile is supported.)
To use Cisco Unified lP Phones 9900 Series, 8900 Series, and 6900 Series as agent devices, the RmCm application user in Unified Communications Manager needs to have "Allow device with connected transfer/conference" option assigned to itself.
Q12. When Single lnbox is configured, what will happen to an email message that was moved from any Outlook folder to the Voice Outbox folder?
A. The email message will be delivered to Cisco Unity Connection.
B. The email message will be kept in the Voice Outbox folder.
C. The move will fail because the operation is not supported.
D. The email message will be moved to the Deleted ltems folder.
E. The email message will be permanently deleted and will not be retrievable.
Answer: D
Explanation:
Voice messages queue for delivery in the Voice Outbox folder that is why it shows in Deleted ltems folder.
Q13. Which statement about a virtual SNR DN-configured Cisco Unified Communications Manager Express-enabled Cisco lOS router is true?
A. Virtual SNR DN supports either SCCP or SlP lP phone DNs.
B. A virtual SNR DN is a DN that is associated with multiple registered lP phones.
C. Calls in progress can be pulled back from the phone that is associated with the virtual SNR DN.
D. The SNR feature can only be invoked if the virtual SNR DN is associated with at least one registered lP phone.
E. A call that arrived before a virtual SNR DN is associated with a registered phone, and still exists after association is made, but cannot be answered from the phone.
Answer: E
Explanation:
Virtual SNR DN only supports Cisco Unified SCCP lP phone DNs.
Virtual SNR DN provides no mid-call support.
Mid-calls are either of the following:
- Calls that arrive before the DN is associated with a registered phone and is still present after the DN is associated with the phone.
- Calls that arrive for a registered DN that changes state from registered to virtual and back to registered.
Mid-calls cannot be pulled back, answered, or terminated from the phone associated with the DN.
State of the virtual DN transitions from ringing to hold or remains on hold as a registered DN. Reference:
