• A. When MLD snooping is enabled, QoS is automatically enabled.
• B. A VLAN can support multiple active MLD snooping queries, as long as each one is associated toa different multicast group.

NEW QUESTION 8
Retef to the exhibit. This network is running OSPF and EIGRP as the routing protocols. Mutual redistribution of the routing protocols has been contoured on the appropriate ASBRs. The OSPF network must be designed so that flapping routes in EIGRP domains do not affect the SPF runs within OSPF. The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains.
Which technique accomplishes the requirement?

• A. route summarization the ASBR interfaces facing the OSPF domain
• B. route summarization on the appropriate ASBRS.
• C. route summarization on the appropriate ABRS.
• D. route summarization on EIDRP routers connecting toward the ASBR

Answer: B

NEW QUESTION 9
Company XYZ is planning to deploy primary and secondary (disaster recovery) data center sites. Each of these sites will have redundant SAN fabrics and data protection is expected between the data center sites. The sites are 100 miles (160 km) apart and target RPO/RTO are 3 hrs and 24 hrs, respectively. Which two considerations must Company XYZ bear in mind when deploying replication in their scenario? (Choose two.)

• A. Target RPO/RTO requirements cannot be met due to the one-way delay introduced by thedistance between sites.
• B. VSANs must be routed between sites to isolate fault domains and increase overall availability.
• C. Synchronous data replication must be used to meet the business requirements
• D. Asynchronous data replication should be used in this scenario to avoid performance impact in theprimary site.
• E. VSANs must be extended from the primary to the secondary site to improve performance andavailability.

Answer: BD

NEW QUESTION 10
Which three tools are used for ongoing monitoring and maintenance of a voice and video environment? (Choose three.)

• B. call management analysis to identify network convergence-related failures
• C. call management analysis to identify CAC failures and call quality issues
• D. active monitoring via synthetic probes to measure loss, latency, and jitter
• E. passive monitoring via synthetic probes to measure loss, latency, and jitter
• F. flow-based analysis with PTP time-stamping to measure loss, latency, and jitter
