NEW QUESTION 84
Refer to the exhibit.

Which impact of using three or more ABRs between the backbone area and area 1 is true?

In a large-scale network LSA replication by all ABRs can cause serious scalability issues

Multiple ABRs reduce the CPU processing on each A6R due to splitting prefix advertisement

In a large-scale network multiple ABRs can create microloops.

Prefixes from the non-backbone area are advertised by one ABR to the backbone

NEW QUESTION 85
Various teams in different organizations within an enterprise are preparing low-level design documents to capture network parameters using a Waterfall project model:
* hardware sizing and power consumption
* Layer 2 and layer 3 services parameters
* configuration of all control plane protocols
Input from relevant stakeholders was captured at the start of the project, and the project scope has been defined based on the parameters above. What impact will it have on documentation and project deliverables if the stakeholders ask to have changes carried out in the network before the information has been captured?

This provides more opportunity to think outside the box.

Rework is expected before the delivery.

Significant effort and time are required.

This provides a flexible approach to incorporate changes.

NEW QUESTION 86
Which two statements describe the usage of the IS-IS overload bit technique? (Choose two )

It can be set in intermediate systems (IS-IS routers) to prioritize control plane CSNP packets.

It can be used to automatically synchronize the link-state database between Level 1 intermediate systems

It can be set in intermediate systems (IS-IS routers) to avoid traffic black holes until routing protocols are fully converged after a reload operation.

It can be set in intermediate systems (IS-IS routers) to attract transit traffic from other intermediate systems

NEW QUESTION 87
Agile and Waterfall are two popular methods for organizing projects. What describes any Agile network design development process?

working design over comprehensive documentation

contract negotiation over customer collaboration

following a plan over responding to change

processes and tools over individuals and interactions over time

synchronous replication over dual data centers via Metro Ethernet

asynchronous replication over geographically dispersed dual data centers via CWDM

Enable and use only secure protocols.

Send logs to a centralized logging collection server.

Implement EBGP to advertise all owned IP blocks.

Use login banners and interface access lists to restrict administrative access to the system

NEW QUESTION 90

Choose a high minimum data rate to reduce the duty cycle.

increases the number of SSlDs to load-balance the client traffic.

Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.

Enable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.

NEW QUESTION 91
Company XYZ connects its sites over a private WAN. Their overlay network is running a DMVPN setup where the headquarters site is the hub. The company is planning on implementing multicast routing on the network. What should be used in the multicast routing design?

PIM dense mode with RP located at the hub

PIM sparse mode with RP located at each remote site

PIM sparse mode with RP located at the hub

PIM dense mode with RP located at each remote site

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

NEW QUESTION 93

NEW QUESTION 95
Customer XYZ network consists of an MPLS core. IS-IS running as IGP a pair of BGP route reflectors for route propagation, and a few dozens of MPLS-TE tunnels for specific tactical traffic engineering requirements. The customer’s engineering department has some questions about the use of the Overload Bit in the IS-IS networks and how it could be used to improve their current network design. Which two concepts about the Overload Bit are true? (Choose two.)

It can be set on a router during the startup process for a fixed period of time

Networks advertised within the LSPs of the respective node will become unreachable

It forces the midpoint MPLS-TE node to reoptimize the primary tunnels going through the OL node.

It can be set on a router until other interacting protocols have signaled convergence.

It is not recommended on BGP Route Reflectors
