  Cisco IOS software supports the following versions of SNMP:

  +

  SNMPv1 ?The Simple Network Management Protocol: A Full Internet Standard, defined in RFC 1157. (RFC 1157 replaces the earlier versions that were published as RFC 1067 and RFC 1098.) Security is based on community strings.

  +

  SNMPv2c ?The community-string based Administrative Framework for SNMPv2. SNMPv2c (the "c" stands for "community") is an Experimental Internet Protocol defined in RFC 1901, RFC 1905, and RFC 1906. SNMPv2c is an update of the protocol operations and data types of SNMPv2p (SNMPv2 Classic), and uses the community-based security model of SNMPv1.

  +

  SNMPv3 ?Version 3 of SNMP. SNMPv3 is an interoperable standards-based protocol defined in RFCs 2273 to 2275. SNMPv3 provides secure access to devices by a combination of authenticating and encrypting packets over the network. The security features provided in SNMPv3 are as follows:

  ?Message integrity: Ensuring that a packet has not been tampered with in transit. ?Authentication: Determining that the message is from a valid source. ?Encryption: Scrambling the contents of a packet prevent it from being learned by an unauthorized source.

• Question 483:

  

  refer to the exhibit , on R1, which routing protocol is in use on the orute to 192.168.10.1?

  A. EIGRP
  B. OSPF
  C. RIP
  D. BGP
  A. EIGRP

• Question 484:

  Refer to the exhibit.

  

  Switch port FastEthernet 0/24 on ALSwitch1 will be used to create an IEEE 802.1Q- compliant trunk to another switch. Based on the output shown, what is the reason the trunk does not form, even though the proper cabling has been attached?

  A. VLANs have not been created yet.
  B. An IP address must be configured for the port.
  C. The port is currently configured for access mode.
  D. The correct encapsulation type has not been configured.
  E. The "no shutdown" command has not been entered for the port.
  C. The port is currently configured for access mode.

  ---

  According to the output shown the switchport (layer 2 Switching) is enabled and the port is in access mode. To make a trunk link the port should configured as a trunk port, not an access port, by using the following command: (Config-if) #switchport mode trunk.

• Question 485:

  Scenario:

  You are a junior network engineer for a financial company, and the main office network is experiencing network issues. Troubleshoot the network issues.

  Router R1 connects the main office to the internet, and routers R2 and R3 are internal routers.

  NAT is enabled on router R1.

  The routing protocol that is enabled between routers R1, R2 and R3 is RIPv2.

  R1 sends the default route into RIPv2 for the internal routers to forward internet traffic to R1.

  You have console access on R1, R2 and R3 devices. Use only show commands to troubleshoot the issues.

  

  

  

  

  R1 router clock is synchronized with ISP router R2 is supposed to receive NTP updates from R1. But you observe that R2 clock is not synchronized with R1. What is the reason R2 is not receiving NTP updates from R1?

  A. The IP address that is used in the NTP configuration on R2 router is incorrect.
  B. The NTP server command not configured on R2 router.
  C. R2 router Ethernet interface that is connected to R1 is placed in shutdown condition.
  D. R1 router Ethernet interface that is connected to R2 is placed in shutdown condition.
  A. The IP address that is used in the NTP configuration on R2 router is incorrect.

• Question 486:

  Which command can you enter to troubleshoot the failure of address assignments?

  A. show ip dhcp pool
  B. show ip dhcp database
  C. show ip dhcp import
  D. clear ip dhcp server statistics
  A. show ip dhcp pool

• Question 487:

  Which of the following is a security best practice?

  A. Use multifactor VPN authentication.
  B. Use only commercially licensed software
  C. Use only WiFi instead of Ethernet cabling
  D. use only solid state hard drives in servers.
  A. Use multifactor VPN authentication.

• Question 488:

  Which statement describes the process ID that is used to run OSPF on a router?

  A. It is globally significant and is used to represent the AS number.
  B. It is locally significant and is used to identify an instance of the OSPF database.
  C. It is globally significant and is used to identify OSPF stub areas.
  D. It is locally significant and must be the same throughout an area.
  B. It is locally significant and is used to identify an instance of the OSPF database.

  ---

  The Process ID for OSPF on a router is only locally significant and you can use the same number on each router, or each router can have a different number-it just doesn't matter. The numbers you can use are from 1 to 65,535. Don't get this confused with area numbers, which can be from 0 to 4.2 billion.

• Question 489:

  Which Rapid PVST+ port role provides a different path to the root bridge?

  A. designated
  B. forwarding
  C. backup
  D. alternate
  D. alternate

• Question 490:

  Which two EXEC mode commands can simplify DHCP lease management? (Choose two)

  A. release dhcp
  B. no ip dhcp conflict logging
  C. Renew dhcp
  D. ip address dhcp
  E. ip dhcp ping timeout 500
  A. release dhcp
  C. Renew dhcp
