Question # 31

Customer traffic from the branch site to the hub is experiencing packet drops. The engineer verified that:

Customer traffic from the hub is able to reach the branch site.

The connection between PE1 and PE2 is working normally.

Routers P1 and P2 are able to ping devices on the hub site.

Which action resolves the issue?

Options:

Redistribute the CE1 OSPF routes in the PE1 VRF.

Redistribute the CE2 OSPF routes in the PE2 VRF.

Advertise the VPNv4 routes of the branch site in CE2.

Advertise the VPNv4 routes of the hub in CE1.

Questions # 32:

The engineering team at ISP_1 must improve network stability time and minimize the impact of routing instabilities from other domains to unicast transit services in the backbone R1 is part of an OSPF- enabled network, and acts as an ASBR connected via interface GiO/1 to the external domain The OSPF exponential backoff algorithm RFC 3623 with helper mode is already implemented on R1 Which additional configuration must the ISP_1 team apply to suppress routing instability for 3 minutes'?

Options:

Configure ip ospf resync-timtout 180 under the Gi0'1 interface configuration

Configure ip ospf timer nsf interval 3 under the global Gi0'1 interface configuration

Configure nsf ittf restart-inttrval 180 under the global OSPF configuration

Configure nsf ospf wait 3 under the global OSPF configuration

Questions # 34:

You have configured MSDP peering between two autonomous systems that pass traffic between two sites, but the peering has failed to come up.

Which task do you perform to begin troubleshooting the problem?

Options:

Verify that multicast has been disabled globally

Verify that PIM-DM is configured on the source interface

Verify that both source interfaces are reachable from both peers

Verify that the two MSDP peers allow asymmetric routing

Question # 35

Early in the growth cycle of a small enterprise the network-engineering team implemented segment routing to support automation of the IPv4 network As the network grew organically more devices were added and the company migrated to SRv6 The company is now planning to significantly expand the number of hosts connected to R2 and R6 which will require further path manipulation Which action must the team take to customize the route that traffic takes between endpoints in the network?

Options:

Implement the flexible algorithm to customize the shortest path through the network

Implement MLAG to reduce traffic load on heavily congested links

Implement spanning-tree protocol to avoid loops between excess devices in the network

Implement priority queuing to drop non-mission-critical traffic.

Question # 36

After troubleshooting BGP traffic steering issue, which action did the network operator

take to achieve the correct effect of this configuration?

Options:

Routes that have passed through AS 65517 have the local preference set to 150.

Routes that have originated through AS 65517 have the local preference set to 150.

Routes directly attached to AS 65517 have the local preference set to 150.

Routes that have passed through AS 65517 have the local preference set to 150 and the traffic is denied.

Question # 37

Expert Solution

Questions # 38:

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.

Expert Solution

Questions # 39:

Which attribute is used to instruct the router that packets must be processed by an ASA that is associated with the segment?

Options:

service SID with service instructions

node SID that identifies a specific network device

prefix SID that represents a specific route prefix

adjacency SID with unidirectional adjacency instructions

Expert Solution

Questions # 40:

Refer to the exhibit.

Question # 40

Why is neighbor 10.1.5.5 stuck in “2WAY” state?

Options:

Router ID 10.1.5.5 is not reachable from R2

OSPF authentication has failed between R2 and 10.1.5.5

It is an expected behavior when OSPF network type is broadcast

OSPF parameters (Area ID or hello interval) are mismatched between R2 and 10.1.5.5
