IS-IS runs in the network and all routers are in the same area R1 statically routes to distribute traffic with R6 and the networking team has redistributed the static routes on R1 into IS-IS Hosts on R3 need access to servers connected to R6 A tag has been applied to the routes to manipulate routes along the path but routers running IS-IS are still unable to reach the redistributed routes Which action must the team take to resolve the issue?

A.

Configure the routers as Level 1/Level 2 routers

B.

Configure R3 with a default route that uses R2 as the next hop

Configure the IS-IS routers with metric-style wide

D.

Configure the route map with an additional route-map set-tag permit 10 sequence

The RA and RB routers reside in the same physical location. Which two configurations must be implemented so that HostB receives the multicast stream even when RB is powered down? (Choose two )

R2(config)# ip prefix-list List1 seq 5 permit 30.1.1.0/24 ge 25 1e

R2(config)# ip prefix-list List1 seq 10 permit 0.0.0.0/le 32

R2(config)# interface fastethernet 0/0

R2(config-if)# ip router isis 122

R2(config-if)# router isis 122

R2(config-router)# distribute-list prefix List1 in

An engineer is addressing an IS-IS design issue which is running within the topology. All

links are running on FastEthernet, except the link between R5 and R4, which is Gigabit Ethernet. Which statement about the design is true?

A.

R4 prefer to reach R5 using R1 as the next hop

B.

All links have equal cost if the default metric is used

C.

R5 prefers to use R4 as the next hop for all routes

D.

R1 prefer to use R5 as the next hop to reach R4

Refer to the exhibit.

CE1 and CE2 are iBGP neighbors in AS 65516. All traffic that exits AS 65516 must use the link from CE1 to PE1. CE1 is advertising a higher local preference to CE2, but traffic from CE2 still prefers the PE2 link. Which action corrects the problem?

A.

Add the lower local-preference value on PE2 towards CE2.

B.

Configure CE1 to send routes to CE2 with a higher MED.

C.

Configure CE1 to send routes to CE2 with a higher weight.

Company_A hosts multiple online VoD platforms. R3 is connected to MAN with a 100 Mbps link R2 has only a 10 Mbps connection, but it has the lowest number of hops to R1 A network engineer must allow users in area 49.421e.2331 5548.7624 00 to access online library resources, using the best possible route toward the online platforms to guarantee the highest connection quality. After the engineer implements the requirements, they notice an excessive number of routes in the R4 routing table and high memory consumption on the router.
