Which option describes an advantage of UDLD?

Which option describes an advantage of UDLD?

Which option describes an advantage of UDLD?

A.
It makes the port go immediately into the forwarding state after being connected.

B.
It prevents switch loops by detecting one-way communications on the physical port.

C.
It prevents switched traffic from traversing suboptimal paths on the network.

D.
It prevents switch loops caused by uni-directional point-to-point link condition on Rapid
PVST+ and MST.

E.
It does not generate a spanning-tree topology change upon connecting and disconnecting a
station on a port.

F.
It allows small, unmanaged switches to be plugged into ports of access switches without the
risk of switch loops.

QUESTION 113
As a service provider you must support a Layer 2 virtualization protocol that does not include the use of label switching. Which option can meet this design requirement?

A. VPLS
B. VRF-Lite
C. QinQ
D. 802.3ad

Answer: C

QUESTION 114
Which two techniques are used in a network design to slow down the distribution of topology information caused by a rapidly flapping link? (Choose two.)

A. Bidirectional Forwarding Detection
B. IP event dampening
C. link-state incremental SPF
D. link-state partial SPF
E. LSA throttling
F. SPF throttling

Answer: BE

QUESTION 115
When designing a WAN that will be carrying real-time traffic, what are two important reasons to
consider serialization delay? (Choose two.)

A. Serialization delays are variable because they depend on the line rate of the interface and on the type
of the packet being serialized.
B. Serialization delay depends not only on the line rate of the interface but also on the size of the packet.
C. Serialization delays are invariable because they depend only on the line rate of the interface.
D. Serialization delays are variable because they depend only on the size of the packet being serialized.
E. Serialization delay is the time required to transmit the packet on the physical media.

Answer: BE

QUESTION 116
In a redesign of a multiple-area network, it is recommended that summarization is to be implemented. For redundancy requirements, summarization is done at multiple locations for each summary. Some customers now complain of higher latency and performance issues for a server hosted in the summarized area.
What design issues should be considered when creating the summarization?

A. Summarization adds CPU overhead on the routers sourcing the summarized advertisement.
B. Summarization prevents the visibility of the metric to the component subnets.
C. Summarization creates routing loops.
D. Summarization causes packet loss when RPF is enabled.

Answer: B

QUESTION 117
Refer to the exhibit. What limitations exist in this design, given that the access layer devices are expected to steadily increase by two devices per week for the next year?

A. scalability
B. serviceability
C. redundancy
D. resiliency

Answer: A

QUESTION 118
What is a key design aspect to be considered when designing an IP network that will be carrying real-time VoIP traffic?

A. Minimizing total bidirectional end-to-end delay to 0-150 ms
B. Minimizing total unidirectional end-to-end delay to 150-500 ms
C. Minimizing total bidirectional end-to-end delay to 0-50 ms
D. Minimizing total unidirectional end-to-end delay to 0-150 ms

Answer: D

QUESTION 119
What is a key role for the access layer in a hierarchical network design?

A. The access layer provides a security, QoS, and policy trust boundary.
B. The access layer provides an aggregation point for services and applications.
C. The access layer serves as a distribution point for services and applications.
D. The access layer can be used to aggregate remote users.

Answer: A

QUESTION 120
You have been asked to deploy BGP across a satellite link system to a small number of retail stores.
What must you do to successfully deploy BGP in this situation?

A. configure all the BGP peering sessions across the satellite links as EBGP
B. set the BGP hold timer to under one second
C. configure the initial window size, maximum MTU, and TCP keepalive parameters
D. manually configure static routes to back up BGP across the satellite link

Answer: C

QUESTION 121
Among the design criteria for a network is the requirement that bandwidth capacity be managed proactively. Which two techniques would most effectively support the proactive management of network bandwidth capacity? (Choose two.)

A. analyze network bandwidth utilization to establish a baseline
B. implement QoS to increase available bandwidth and overall throughput
C. implement utilization measurement and tracking measures in the network
D. configure SNMP MIB collectors to trigger at utilization thresholds

Answer: AC

QUESTION 122
What are the two preferred mechanisms for detecting Layer 2 link failures quickly? (Choose two.)

A. BFD
B. fast RSVP hellos
C. LDP keepalives
D. loss of signal

Answer: AD

B. broadcast
C. anycast
D. multicast

Answer: C

QUESTION 124
Which network management tool should a network manager consult in order to pinpoint the cause of a routing recursion error?

A. debug (for BGP output)
B. syslog (for BGP errors)
C. RMON events group
D. SNMP routing traps

Answer: A

QUESTION 125
