Questions # 2:

Refer to the exhibit.

Question # 2

Routers RA and RB are IS-IS peers configured for NSF but router RC is an IS-IS peer without NSF capability If RA undergoes processor switchover what is the effect on the network environment?

Options:

If RC is operating without the Cisco configuration option all three routers tear down their peering relationships and re-establish peering

All peer relationships remain up and the link-state database is unchanged

All peer relationships remain up, but the link-state database is rebuilt on each device

If RC is operating without the Cisco configuration option only 2 routers tear down their peering relationships and re-establish peering

Questions # 3:

Level 3 switch SW1 is part of an EIGRP enabled network located at the edge of an area. Cisco Express Forwarding and SSO are enabled on the router. A network engineer must minimize the downtime of data-transmit services in the network. HSRP group 2 has already been configured with standby preempt delay minimum 2 and standby timers 140. Which additional action must the engineer take on SW1 to suppress routing flaps for 2 minutes?

Options:

Configure timers standby 2 wait 2 under the HSRP group 2 configuration.

Configure timers nsf route-hold 120 under the global EIGRP configuration.

Configure timers nsf signal 2 under the global EIGRP IPv4 address family.

Configure timers standby 2 coverage 120 under the HSRP group 2 configuration.

Question # 4

A network engineer at a large ISP with an employee ID 4876 94 052 started to configure OSPF on two routers The engineer notices that router 1 learned about network 20 20 20 0/24 from router 2, but router 2 did not learn about 10.10 10.0/24 from router 1 Layer 2 and Layer 3 connectivity are working between the two routers and the physical connection between the devices is functioning. Which action must the engineer take to resolve the issue?

Options:

Replace the router 1 OSPF network configuration with network 10.10.10.0 0.0.0.255 area 0.

On router 1 configure a route map with a distribution list for the 10 10.10 0/24 network.

Replace the router 2 OSPF network configuration with network 10.10.10.0 0.0.0.255 area

On router 2 configure a route map with a distribution list for the 101010 0/24 network

Questions # 5:

Refer to the exhibit.

Question # 5 .

R1 is expected to receive routes originating from AS 65516 and from any ASs that are directly attached to it. However, R1 is receiving routes only from AS 65516. Which action corrects the configuration?

Options:

Change the regular expression in the AS-path permit filter to .*.

Change the regular expression in the AS-path permit filter to ^65516_[0-9]*$.

Add the regular expression ^$. in the AS-path filter to permit the traffic from R2.

Change the regular expression in the AS-path permit filter to _65516_.

Questions # 6:

Refer to the exhibit.

Question # 6

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?

Options:

Configure the routers as Level 1/Level 2 routers

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

Configure the IS-IS routers with metric-style wide

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

Expert Solution

Questions # 7:

Which statement about BFD on Cisco IOS XR Software is true?

Options:

Cisco IOS XR router must use LDP to route back to the Cisco IOS router to establish the peer relationship.

Cisco IOS XR Software does not support BFD multihop for IPv4.

Cisco IOS XR router must use dynamic routing or a static route back to the Cisco IOS router to establish the peer relationship.

BFD is not compatible between Cisco IOS XR and Cisco IOS Software.

Questions # 8:

Question # 8

Refer to the exhibit. Router R1 is expected to receive routes that originate from AS 65547 only. However, R1 is receiving routes from AS 65547 and several other ASs that are directly attached to it. Which change to the AS path permit filter corrects the problem?

Options:

Change the regular expression to $.

Change the regular expression to.*.

Change the regular expression to _65547_.

Change the regular expression to A65547$

Questions # 9:

Question # 9

Refer to the exhibit. Unified MPLS is implemented on this network to provide end-to-end services A network engineer noticed that R3 is failing to receive labels from R1 However, R2 is receiving labels from R1 R3 can ping R1 normally Which action resolves the issue?

Options:

Add the cdp run command to the link configuration between R1 and R3.

Add the send-label keyword in the R1 neighbor statement for R3.

Configure R1 to run Unified MPLS on both interfaces.

Disable mpls Ip on the link between R1 and R3

Expert Solution

Questions # 10:

Refer to the exhibit.

Question # 10

R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3

is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result between

BGP peers R1, R2 and R1, R3 is true?

Options:

The BGP session does not come up between R1 and R2 and between R1 and R3.

The BGP session comes up between R1 and R2 and between R1 and R3.

The BGP session comes up between R1 and R3, but not between R1 and R2.

The BGP session comes up between R1 and R2, but not between R1 and R3.
