Branch1# clock set 08:00:00 05 AUG 2013

What is the purpose of utilizing Diffie-Hellman (DH) algorithms as part of the IPsec standard?

DH algorithms allow two parties to establish a shared secret key that is used by encryption and hash algorithms.

How can SNMP access be restricted to a specific SNMP manager?

Define an ACL and reference it by using the snmp-server community command.

What key question would help determine whether an organization should use an SSL VPN or an IPsec

Do users need to be able to connect without requiring special VPN software?

What key question would help determine whether an organization should use an SSL VPN or an IPsec VPN for the remote access solution of the organization?

Do users need to be able to connect without requiring special VPN software?

What is an IPsec protocol that provides data confidentiality and authentication for IP packets?

ESP

When logging is used, which severity level indicates that a device is unusable?

Emergency-Level 0

Which three statements describe the building blocks that make up the IPsec protocol framework? (Choose three.)

IPsec uses encryption algorithms and keys to provide secure transfer of data. IPsec uses secret key cryptography to encrypt messages that are sent through a VPN. IPsec uses ESP to provide confidential transfer of data by encrypting IP packets.

Which statement correctly describes IPsec?

IPsec works at Layer 3, but can protect traffic from Layer 4 through Layer 7.

Which statement describes a characteristic of IPsec VPNs?

IPsec works with all Layer 2 protocols.

A network administrator issues two commands on a router: R1(config)# snmp-server host 10.10.50.25 version 2c campus R1(config)# snmp-server enable traps What can be concluded after the commands are entered?

If an interface comes up, a trap is sent to the server.

Which statement describes a feature of site-to-site VPNs?

Internal hosts send normal, unencapsulated packets.

What is the purpose of a message hash in a VPN connection?

It ensures that the data has not changed while in transit.

A network administrator has issued the snmp-server user adminl admin v3 encrypted auth md5 abc789 priv des 256 key99 command. What are two features of this command? (Choose two.)

It uses the MD5 authentication of the SNMP messages. It adds a new user to the SNMP group.

Which two algorithms use Hash-based Message Authentication Code for message authentication? (Choose two.)

MD5 SHA

What is a difference between SNMP and NetFlow?

NetFlow collects more detailed traffic statistics on IP networks than SNMP does.

Which two statements describe items to be considered in configuring NetFlow? (Choose two.)

Netflow can only be used in a unidirectional flow. Netflow consumes additional memory.

How is "tunneling" accomplished in a VPN?

New headers from one or more VPN protocols encapsulate the original packets.

How does NetFlow function on a Cisco router or multilayer switch?

One user connection to an application exists as two NetFlow flows.

How does NetFlow function on a Cisco router or multilayer switch? Netflow captures and analyzes traffic.

One user connection to an application exists as two NetFlow flows.

Which algorithm is an asymmetrical key cryptosystem?

RSA

Which SNMP feature provides a solution to the main disadvantage of SNMP polling?

SNMP trap messages

Refer to the exhibit. A tunnel was implemented between routers R1 and R2. Which two conclusions can be drawn from the R1 command output? (Choose two.)

The data that is sent across this tunnel is not secure. A GRE tunnel is being used.

A network administrator has issued the logging trap 4 global configuration mode command. What is the result of this command?

The syslog client will send to the syslog server any event message that has a severity level of 4 and lower.

Refer to the exhibit. Which two conclusions can be drawn from the syslog message that was generated by the router? (Choose two.)

This message is a level 5 notification message. This message indicates that service timestamps have been configured.
