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.)
Target RPO/RTO requirements cannot be met due to the one-way delay introduced by the distance between sites.
VSANs must be routed between sites to isolate fault domains and increase overall availability.
Synchronous data replication must be used to meet the business requirements
Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.
VSANs must be extended from the primary to the secondary site to improve performance and availability.
Which undesired effect of increasing the jitter compensation buffer is true?
The overall transport jitter decreases and quality improves.
The overall transport jitter increases and quality issues can occur.
The overall transport delay increases and quality issues can occur.
The overall transport delay decreases and quality improves.
Which three tools are used for ongoing monitoring and maintenance of a voice and video environment? (Choose three.)
flow-based analysis to measure bandwidth mix of applications and their flows
call management analysis to identify network convergence-related failures
call management analysis to identify CAC failures and call quality issues
active monitoring via synthetic probes to measure loss, latency, and jitter
passive monitoring via synthetic probes to measure loss, latency, and jitter
flow-based analysis with PTP time-stamping to measure loss, latency, and jitter
Which two advantages of using DWDM over traditional optical networks are true? (Choose two.)
inherent topology flexibility and service protection provided without penalty through intelligent oversubscription of bandwidth reservation
ability to expand bandwidth over existing optical Infrastructure
inherent topology flexibility with built-in service protection
inherent topology flexibility with intelligent chromatic dispersion
inherent topology flexibility with a service protection provided through a direct integration with an upper layer protocol

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 m 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?
route summarization the ASBR interfaces facing the OSPF domain
route summarization on the appropriate ASBRS.
route summarization on the appropriate ABRS.
route summarization on EIDRP routers connecting toward the ASBR
Company XYZ is running OSPF in their network. They have merged with another company that is running EIGRP as the routing protocol. Company XYZ now needs the two domains to talk to each other with redundancy, while maintaining a loop free environment. The solution must scale when new networks are added into the network in the near future. Which technology can be used to meet these requirements?
multipoint route-redistribution with route filtering using ACLs
DUMP multipoint route-redistribution with route filtering using route tags
DUMPS single point route-redistribution with route filtering using route tags
DUMPS single point route-redistribution with route filtering using ACLs
Company XYZ is in the process of identifying which transport mechanism(s) to use as their WAN technology. Their main two requirements are.
• a technology that could offer DPI, SLA, secure tunnels, privacy, QoS, scalability, reliability, and ease of management
• a technology that is cost-effective
Which WAN technology(ies) should be included in the design of company XYZ?
Software-defined WAN should be the preferred choice because it complements both technologies, covers all the required features, and it is the most cost-effective solution.
Internet should be the preferred option because it is cost effective and supports BFD, IP SLA. and IPsec for secure transport over the public Internet.
Both technologies should be used. Each should be used to back up the other one; where the primary links are MPLS, the internet should be used as a backup link with IPsec (and vice versa).
MPLS meets all these requirements and it is more reliable than using the Internet. It is widely used with defined best practices and an industry standard.
Company XYZ asks for design recommendations for Layer 2 redundancy. The company wants to prioritize fast convergence and resiliency elements. In the design. Which two technologies are recommended? (Choose two.)
Design MLAG/MC-LAG into the network wherever possible.
Configure DHCP snooping on the switches.
Use root guard.
Use BPDU guard.
Use UniDirectional Link Detection.

An engineer is designing a multiarea OSPF network for a client who also has a large EIGRP domain EIGRP routes are getting redistributed into OSPF ,OSPF area 20 has routers with limited memory and CPU resources The engineer wants to block routes from EIGRP 111 from propagating into area 20 and allow EIGRP 222 routes to How in Which OSPF area type fulfills this design requirement?
area 20 as a stub area
type 5 LSA filtering on the ASBR between EIGRP 111 and area a
area 20 as a NSSA area
type 3 LSA filtering on the ABR between area 0 area 20
