Q5. You have just enabled IS-IS on the lab testing network. You notice that IS-IS is not using the optimal path selection based on the interface bandwidth. Currently, the IS-IS routing process seems to be selecting the best path based on the hop count. 

What configuration change can you make to cause IS-IS to select the optimal path based on the interface bandwidth? 

A. Enable a wide-style IS-IS metric. 

B. Enable a narrow-style IS-IS metric. 

C. Change the default auto-cost reference bandwidth to a higher value. 

D. Change the default IS-IS metric on each of the router interfaces to better correspond to the interface bandwidth. 

E. Change the interface bandwidth by using the bandwidth interface configuration mode command. 

Answer: D 

Q6. Which type of service provider is responsible for offering backbone connectivity services to other service providers? 

A. CSP 

B. TSP 

C. NSP 

D. ISP 

E. ASP 

Answer: C 

Q7. You want to configure HSRP between a Cisco IOS and a Cisco IOS XR router for the 192.0.2.0/24 subnet. Half of the PCs on the 192.0.2.0/24 subnet are configured to use 192.0.2.1 as the default gateway, and the other half of the PCs are configured to use 192.0.2.254 as the default gateway. The intent is to load balance the traffic across both routers. 

Which two IOS and IOS XR configurations are needed? (Choose two.) 

A. 

! IOS-XR interface GigabitEthernet 0/0/0/0 ip address 192.0.2.3 255.255.255.0 router hsrp interface GigabitEthernet 0/0/0/0 hsrp 1 ipv4 192.0.2.1 hsrp 1 priority 95 hsrp 1 preempt hsrp 2 ipv4 192.0.2.254 hsrp 2 priority 105 hsrp 2 preempt 

B.

C.

D. 

! IOS interface GigabitEthernet 0/0 ip address 192.0.2.2 255.255.255.0 standby 1 ip 192.0.2.1 standby 1 priority 105 standby 1 preempt standby 2 ip 192.0.2.254 standby 2 priority 95 standby 2 preempt !

C. ACLs always search for the most specific entry before taking any filtering action. 

D. Router-generated packets cannot be filtered by the interface ACLs on the router. 

E. Extended ACLs should be placed as close to the destination as possible. 

F. There must be at least one permit statement in an ACL, or all traffic is denied. 

Answer: A,D,F 

Q9. Refer to the exhibit.
