Question # 61

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

Options:

A.

In a large-scale network, LSA repletion, by all ABRs. can cause serious scalability issues


B.

Prefixes from the non-backbone area ate advertised by one ABR lo the backbone area


C.

Multiple ABRs reduce the CPU processing on each ABR due to spWtmg prefix advertisement between areas.


D.

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

Question # 64

ACME Mining has four data centers in Santiago, Cape Town, Mumbai, and Beijing. They are full-mesh connected via a 400 Mb/s EVP-LAN. A 1-TB transfer occurs daily via FTP between the Santiago and Mumbai data centers. When testing, the data transfer took an ''unexpected and outrageous, with an average transfer rate of 47 KB/s. The team provided this information.

LAN bandwidth usage below 5% at both data centers during transfer.

WAN bandwidth usage was between 20-30% at both data centers during transfer.

The only QoS on WAN is KB/s strict priority configured for other types of traffic.

There is no QoS on LAN.

The ping RTT average between data centers is 378 milliseconds.

Which action improves the file transfer rate?

Options:

A.

Use SFTP instead of FTP


B.

Apply optimization techniques at both data centers.


C.

Use TFTP instead of FTP.


D.

Classify FTP transfer and use the strict priority queue on the WAN.

Questions # 65:

A network engineering team is in the process of designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS traffic Engineering Fast Reroute solution has the same failover/failback times as a traditional SONET/SDH network (around 50MSEC). In order to address both link failure and node failure within the lab typology network, which type of the MPLS TE tunnels must be considered for this demonstration?

Options:

A.

TE backup tunnel


B.

Next-hop (NHop) tunnel


C.

FRR Backup tunnel


D.

next-next-hop (NNHop) tunnel

Questions # 66:

A data center deign requires monitoring of their business critical voice and video services accessed by remote locations. Which two items are applicable? (Choose two)

Options:

A.

If multiple applications share the same DSCP or CoS values, NBAR can be utilized


B.

The applications being monitored must be assigned a unique CoS value


C.

If multiple applications share the same the same DSCP or CoS values, IPFIX can be utilized


D.

The applications being monitored must be assigned a unique QoS profile


E.

The applications being monitored must be assigned unique DSCP values


F.

The reporting data must be assigned to a QoS profile to ensure accurate statistics

Questions # 67:

What is a design benefit of PortFast?

Options:

A.

PortFast allows small, unmanaged switches to be plugged into ports of access switches without risking switch loops


B.

PortFast disables spanning-tree on the port, which puts the port into the forwarding state immediately after it is connected


C.

Portfast does not generate a spanning-tree topology change when a station on a port is connected or disconnected


D.

PortFast detects one-way communications on the physical port, when prevents switch loops


E.

PortFast prevents switched traffic from traversing suboptimal paths on the network


F.

PortFast prevents switch loops that are caused by a unidirectional point-to-point link condition on Rapid PVST+ and MST


Expert Solution
Questions # 68:

Which two reasons for implementing Cisco MPLS TE in a service provider MPLS backbone are valid? (Choose two.)

Options:

A.

when Cisco MPLS TE is a prerequisite for implementing RSVP in the backbone


B.

when Cisco MPLS TE is required to reroute traffic within Jess than 1 second in case of a link failure inside the backbone


C.

when Cisco MPLS TE is required to create backup paths independently from the IGP


D.

when Cisco MPLS TE can detect and react to neighbor failures faster than IGPs can


E.

when Cisco MPLS TE is required to route different MPLS QoS service classes through different paths

Question # 69

You have designed a IPv6 migration plan, and now you need to determine the impact on the existing IPv4 network. Which is likely to happen when you enable IPv6 routing on the link between R3 and R2, starting at R3?

Options:

A.

R3 advertises the link from R3-R2 to R1, R4 and R5 only.


B.

R2 receives an IPv6 default route from R3.


C.

Only R3 and R2 have IPv4 and IPv6 reachability.


D.

Loopback reachability between all routers for IPv4 is lost.


E.

All routers except R2 are reachable through IPv4.

Questions # 70:

ACME Agricultural requires that access to all network devices is granted based on identify validation, and an authentication server was installed for this purpose. Currently the network team uses a list of passwords based on regions to access the internal corporate network devices. Which protocol do you recommend to ensure identify validation from the authentication server to the corporate directory?

Options:

A.

HTTPS


B.

TACACS+


C.

SSH


D.

LDAP
