Question # 50

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?

A.

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

B.

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

C.

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

D.

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

Question # 51

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?

A.

Change the regular expression to $.

B.

Change the regular expression to.*.

C.

Change the regular expression to _65547_.

D.

Change the regular expression to A65547$

Question # 52

Refer to the exhibit. HostB receives an IPTV traffic stream from the multicast source at 192.168 10.1. When router RB is powered down, it impacts multicast traffic forwarding to downstream peers. 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 )

A.

Enable PIM sparse mode on routers RC and RZ with a static RP address of 10.10.10.1.

B.

Set the backup RP address to 10 10 10.3 on routers RY and RZ.

C.

Enable bi-directional PIM on all routers.

D.

Enable PIM SSM mode on routers RA and RY.

E.

Set the RP address to 10.10.10.4 on all routers

Question # 53

Which two statements about mapping multicast IP addresses to MAC addresses are true? (Choose two.)

A.

All mapped multicast MAC addresses begin with 0x0100.5E

B.

The router performs the mapping before it hands the packet off to a switch

C.

All multicast MAC addresses end with 0x0100.5E

D.

The mapping process may generate overlapping addresses, which can cause receivers to receive

unwanted packets

E.

All destination MAC addresses begin with an octet of binary 1s

Question # 55

Refer to the exhibit.

What is the relationship between Router 1 and Router 2?

A.

Router 1 centrally learns the topology of the network to aid in SR-TE path selection, and Router 2 is a node that feeds Router 1 topology information.

B.

Router 1 and Router 2 are participating in SR-TE tunnels and are both head-end routers.

C.

Router 1 and Router 2 centrally learn the topology of the network to aid in SR-TE path selection for peers.

D.

Router 2 is the head-end router in an SR-TE tunnel, and it is learning topology of the network from the PCE enabled on Router 1.
