NO.1 Which statement about G.722.1 codec support on Cisco Unified Communications Manager is
true?
A. It is always preferred by Cisco Unified Communications Manager over G.711.
B. It is a high-complexity wideband codec.
C. It operates at bit rates of 15.2 and 13.3 kb/s.
D. It is supported for SIP and SCCP devices.
E. It is supported for SIP and H.323 devices.
Answer: E
Explanation:
G.722.1 is a low-complexity wideband codec operating at 24 and 32 kb/s. The audio quality
approaches that of G.722 while using at most half the bit rate. As it is optimized for both speech and
music, G.722.1 has slightly lower speech quality than the speech-optimized iSAC codec. G.722.1 is
supported for SIP and H.323 devices.

NO.2 In Cisco IOS routers, which chipset is the PVDM2-32 DSP hardware based on?
A. C5441
B. C549
C. C5510
D. C5421
E. Broadcom 1500
Answer: C

NO.3 Which statement about application inspection of SAF network services on an adaptive
security appliance is true?
A. The adaptive security appliance can inspect and learn the ephemeral port numbers that are used
by H.225 and H.245 on SAF-enabled H.323 trunks.
B. An explicit ACL must be configured on the adaptive security appliance for SAF-enabled SIP trunks.
C. An explicit ACL must be configured on the adaptive security appliance for SAF-enabled
H.323 trunks to account for ephemeral port numbers that are used by H.225 and H.245.
D. The adaptive security appliance can inspect and learn the ephemeral port numbers that are used
by H.225 on SAF-enabled H.323 trunks, but H.245 ports must be explicitly defined.
E. The adaptive security appliance provides full application inspection for SAF network services.
Answer: C
Explanation:
The Adaptive Security Appliances do not have application inspection for the SAF network service.
When Unified CM uses a SAF-enabled H.323 trunk to place a call, the ASA cannot inspect the SAF
packet to learn the ephemeral port number used in the H.225 signalling. Therefore, in scenarios
where call traffic from SAF-enabled H.323 trunks traverses the ASAs, ACLs must be configured on the
ASAs to allow this signaling traffic. The ACL configuration must account for all the ports used by the
H.225 and H.245 signaling.

NO.4 Which statement about the effective path in the Enhanced Location Call Admission Control
mechanism on Cisco Unified Communications Manager is true?
A. It is a sequence of links and intermediate locations that connect a pair of locations.
B. It is used to define the bandwidth that is available between locations.
C. Only one effective path is used between two locations.
D. There could be multiple effective paths between a pair of locations.
E. It logically represents the WAN link.
Answer: C
Explanation:
The effective path is the path used by Unified CM for the bandwidth calculations, and it has the least
cumulative weight of all possible paths. Weights are used on links to provide a "cost" for the
"effective path" and are pertinent only when there is more than one path between any two locations
.

NO.5 Which two statements about the restrictions for support of H.239 are true? (Choose two.)
A. SIP to H323 video calls using H.239 are not supported.
B. Redundancy for H.323 calls is not supported.
C. H.239 calls are not supported over intercluster trunks with Cisco Unified Communications
Manager.
D. H.239 is not supported with third-party endpoints.
E. Cisco Unified Communications Manager supports a maximum of three video channels when using
H.239.
Answer: A,B

NO.6 Which statement describes the Cisco best practice recommendation about priority queue
bandwidth allocation in relationship to the total link bandwidth when multiple strict priority LLQs are
configured on the same router interface?
A. Each LLQ should be limited to one-third of the link bandwidth capacity.
B. The sum of all LLQs should be limited to two-thirds of the link bandwidth capacity.
C. The sum of all LLQs should be limited to one-half of the link bandwidth capacity.
D. The sum of all LLQs should be limited to one-third of the link bandwidth capacity.
E. Cisco does not recommend more than one strict priority LLQ per interface.
Answer: D
Explanation:
Cisco Technical Marketing testing has shown a significant decrease in data application response times
when Real-Time traffic exceeds one-third of a link's bandwidth capacity. Cisco IOS Software allows
the abstraction (and, thus, configuration) of multiple LLQs. Extensive testing and production-network
customer deployments have shown that limiting the sum of all LLQs to 33 percent is a conservative
and safe design ratio for merging real-time applications with data applications.

NO.7 Refer to the exhibit.
A user is going through a series of dialing steps on a SIP Type A IP phone to call a SCCP IP phone. Both
phones are registered to the same Cisco Unified Communications Manager cluster. Assume that the
calling SIP phone is not associated with any SIP dial rules.
Which statement about how digits are forwarded to the Cisco Unified Communications Manager for
further call processing is true?
A. As each digit is pressed on the SIP IP phone, it is sent to the Cisco Unified Communications
Manager in a SIP NOTIFY message as a KPML event.
B. The SIP IP phone waits for the inter-digit timer expiry and then sends each digit to the Cisco
Unified Communications Manager as a separate KPML event in a SIP NOTIFY message.
C. The SIP IP phone waits for the inter-digit timer expiry or for the Dial soft key to be selected before
it sends all digits to the Cisco Unified Communications Manager in a SIP INVITE message.
D. The SIP IP phone waits for the inter-digit timer expiry, or for the Dial soft key to be selected before
it sends the first digit in a SIP INVITE and the subsequent digits in SIP NOTIFY messages.
E. The SIP IP phone sends all digits to the Cisco Unified Communications Manager in a SIP INVITE
message as soon as the fourth digit is pressed.
Answer: C
