Question 151
Refer to the exhibit. An engineer is designing a Layer 2 campus network. The design must support fast convergence and leverage as much bandwidth as possible between layers. Distribution switches do support VSS; unfortunately, not all routing protocols are available for use due to license limitations. Which solution must the engineer choose?
A. EtherChannel
B. MEC
C. RSTP
D. ECMP
Question 152
Refer to the exhibit. A customer experienced an unexpected network outage when the link between R1 and R2 went down. An architect must design a solution to ensure network continuity in the event the link tails again. Which solution should the design include?
A. Make R3 an L1L2 router.
B. Make R31 an L1 router.
C. Make Area 0 L2-only.
D. Make R11 an L2 router.
Question 153
Refer to the exhibit. An architect is developing a solution to consolidate networks while retaining device redundancy. The routing protocol for the WAN routers must be open standard, ensure high availability, and provide the fastest convergence time. Which solution must the design include?
A. both routers running EIGRP
B. one router running OSPFv2 and other OSPF v3
C. one router running ISIS and other OSPF v3
D. both routers running OSPFv2
Question 154
Refer to the exhibit. An architect is designing a network for a customer supporting a Wake-on-LAN application. Which solution must the architect choose?
A. IP directed-broadcasts on R1
B. spanning-tree uplinkfast on SW1
C. spanning-tree uplinkfast on SW2
D. IP directed-broadcasts on R2
Question 155
An engineer is designing an IPv4 addressing plan for an enterprise with 1000 branches. Each branch requires a prefix for data and a prefix for voice. Each prefix must accommodate up to 128 hosts, and prefixes must facilitate summarization at aggregation points in the network. The security team requires a simple method for identifying voce prefixes. Which allocation does the engineer recommend from the RFC1918 address space?
A. /24 prefixes for data from 10.0.0.0/15 and /24 prefixes for voice from 172.16.0.0/15
B. /24 prefixes for data from 10.0.0.0/8 and /24 prefixes for voice from the next contiguous /24 prefix per site
C. /25 prefixes for data from 10.0.0.0/8 end /25 prefixes for voice from the next contiguous /25 prefix per branch
D. /24 prefixes for data from 10.0.0.0/8 and /24 prefixes for voice from 172.16.0.0/12
Question 156
An engineer is designing a PIM Anycast RP solution between two data centers. The design must ensure that RP1 in DC1 and RP2 in DC2 inform each other about specific sources that have joined locally. Which solution must the engineer choose?
A. Provision the RPs on the same IP subnet and extend the subnet at Layer 2 between data centers
B. Enable MSDP between RPs using separate unique loopback interfaces
C. Enable MSDP between RPs using the configured Anycast RP address
D. No action is required because PIM registers from the source will, by default, reach each RP
Question 157
An engineer is designing a BGP network for a large customer. To permit efficient scaling, the BGP domain is split into clusters. Which peering solution should be used between the route reflectors in different clusters for the BGP routes to be propagated appropriately?
A. The route reflectors should be made dents of each other.
B. The route reflectors should be nonclients with regards to each other.
C. The route reflectors should not have any kind of BGP peering.
D. The route reflectors should have peering through another nonclient router.
Question 158
A company uses cloud-based applications for voice and video calls, file sharing, content sharing, and messaging. During business hours, these applications randomly become slow and unresponsive. However, other applications work smoothly with the current applied QoS polices. Which solution must the company choose to resolve the issue?
A. Identify the applications with NBAR2 and allocate the required bandwidth accordingly.
B. Identify the port used by each application and apply a minimum bandwidth guarantee.
C. Identify the applications and reserve the required bandwidth on the perimeter routers.
D. Identify the application ports, create groupings, and rate-limit the required bandwidth.
Question 159
DRAG DROP -Drag and drop the model-driven telemetry considerations from the left onto the modes they apply to on the right.
Select and Place:
Question 160
Which design achieves SD-WAN control plane redundancy?
A. Configuring BFD on the WAN Edge routers
B. Using multiple instances of vManage in clusters
C. Deploying using a virtual platform like UCS or CSP
D. Managing the underlay network with OMP
