Refer to the exhibit. The company has provided IP phones to employees on the 192.168.10.0/24 network and the voice traffic will need priority over data traffic. What is the best ACL type and placement to use in this situation?

• • extended ACL inbound on R1 G0/0

• • standard ACL inbound on R1 vty lines

• • standard ACL inbound on R1 G0/1

• • extended ACL inbound on R3 G0/0

An ACL is applied inbound on a router interface. The ACL consists of a single entry:

access-list 210 permit tcp 172.18.20.0 0.0.0.31 172.18.20.32 0.0.0.31 eq ftp .

If a packet with a source address of 172.18.20.14, a destination address of 172.18.20.40, and a protocol of 21 is received on the interface, is the packet permitted or denied?

• • permitted

• • denied

Refer to the exhibit. Router R1 is configured with static NAT. Addressing on the router and the web server are correctly configured, but there is no connectivity between the web server and users on the Internet. What is a possible reason for this lack of connectivity?

• • The router NAT configuration has an incorrect inside local address.

• • The inside global address is incorrect.

• • Interface Fa0/0 should be configured with the command ip nat outside .

• • The NAT configuration on interface S0/0/1 is incorrect.

Refer to the exhibit. Which address or addresses represent the inside global address?

• • 10.1.1.2

• • 192.168.0.100

• • any address in the 10.1.1.0 network

• • 209.165.20.25

What are two benefits of using SNMP traps? (Choose two.)

• • They reduce the load on network and agent resources.

• • They limit access for management systems only.

• • They eliminate the need for some periodic polling requests.

• • They can passively listen for exported NetFlow datagrams.

• • They can provide statistics on TCP/IP packets that flow through Cisco devices.

Refer to the exhibit. From which location did this router load the IOS?

• a TFTP server

• • flash memory

• • NVRAM​

• • RAM

• ROM

What protocol uses smaller stratum numbers to indicate that the server is closer to the authorized time source than larger stratum numbers?

• • NTP

• • SYSLOG

• • TFTP

• • MPLS

Which step in the link-state routing process is described by a router flooding link-state and cost information about each directly connected link?

• • electing the designated router

• • exchanging link-state advertisements

• • injecting the default route

• • building the topology table

How does virtualization help with disaster recovery within a data center?

• • Server provisioning is faster.

• • Power is always provided.

• • Less energy is consumed.

• • Hardware at the recovery site does not have to be identical to production equipment.
