Options:

A.

Increase the hello timers on both HSRP devices

B.

Use the preempt delay feature on the primary HSRP device.

C.

Use the preempt delay feature on the backup HSRP device

D.

Questions # 34:

An engineer is designing a networking solution to allow two hosts to communicate—one host located within the company A network and the other within the company B network. The two companies have no other plans for future additional connections. Both companies want to use a single secure and encrypted internet connection, and the configuration must be as simple as possible. Which network solution must the engineer choose?

Options:

A.

single DMVPN with EIGRP routing

B.

routed IPsec tunnel with OSPF routing

C.

policy-based IPsec tunnel with static routing

D.

MPLS VPN provided service with BGP routing
