Which one of these is a valid HSRP Virtual Mac Address?
What Cisco IOS feature can be enabled to pinpoint an application that is causing slow network performance? Your Answer:
What are three reasons to collect Netflow data on a company network?
To identify applications causing congestion. To diagnose slow network performance, bandwidth hogs, and bandwidth utilization. To confirm the appropriate amount of bandwidth that has been allocated to each Class of Service. Explanation:
an embedded instrumentation within Cisco IOS Software to categorize and track network traffic.
Which three statements about the features of SNMPv2 and SNMPv3 are true?
SNMPv3 enhanced SNMPv2 security features. SNMPv2 added the Inform protocol message to SNMP. SNMPv2 added the GetBulk protocol message to SNMP.
In GLBP, which router will respond to client ARP requests?
The active virtual gateway will reply with one of four possible virtual MAC addresses.
In a GLBP network, who is responsible for the ARP request?
Gateway Load Balancing Protocol
Gateway Load Balancing Protocol (GLBP)
provides redundancy for IP networks, ensuring that user traffic immediately and transparently recovers from first hop router failures, while allowing packet load sharing between a group of redundant routers.
Which two tasks does the Dynamic Host Configuration Protocol perform?
Configure IP address parameters from DHCP server to a host. Assign and renew IP address from the default pool.
When a DHCP server is configured, which two IP addresses should never be assignable to hosts?
Network or subnetwork IP address Broadcast address on the network
What does the "Inside Global" address represent in the configuration of NAT?
A registered address that represents an inside host to an outside network.
What are three factors a network administrator must consider before implementing Netflow in the network?
CPU utilization where Netflow data will be sent number of devices exporting Netflow data
Network Address Translation
Which three statements about HSRP operation are true?
The virtual IP address and virtual MAC address are active on the HSRP Master router. The HSRP default timers are a 3 second hello interval and a 10 second dead interval. HSRP supports up to 255 groups per interface, enabling an administrative form of load balancing.
How does a DHCP server dynamically assign IP addresses to hosts?
Addresses are leased to hosts. A host will usually keep the same address by periodically contacting the DHCP server to renew the lease.
is used to enable individual computers on an IP network to extract their configurations from a server (the DHCP server) or servers.
Which of the following statements are TRUE regarding Cisco access lists?
In an inbound access list, packets are filtered as they enter an interface. Extended access lists are used to filter protocol-specific packets.
What are two benefits of using NAT?
NAT protects network security because private networks are not advertised. NAT eliminates the need to re-address all host that require external access.
A network administrator is configuring ACLs on a Cisco router, to allow traffic from hosts on networks 192.168.146.0, 192.168.147.0, 192.168.148.0, and 192.168.149.0 only. Which two ACL statements, when combined, would you use to accomplish this task?
Which three statements about Syslog utilization are true?
A Syslog server provides the storage space necessary to store log files without using router disk space. There are more Syslog messages available within Cisco IOS than there are comparable SNMP trap messages. A Syslog server helps in aggregation of logs and alerts.
A network engineer wants to allow a temporary entry for a remote user with a specific username and password so that the user can access the entire network over the Internet. Which ACL can be used?
Which command encrypts all plaintext passwords?
Router(config)# service password-encryption
Which two statements about static NAT translations are true?
They are always present in the NAT table. They allow connection to be initiated from the outside.
The Management Information Base (MIB) is a virtual information storage area for network management information, which consists of collections of managed objects.
Manager - NMS
The SNMP manager is the system used to control and monitor the activities of network hosts using SNMP.
Which statement describes VRRP object tracking?
It ensures the best VRRP router is the virtual router master for the group.
VRRP Object Tracking
VRRP object tracking provides a way to ensure the best VRRP router is virtual router master for the group by altering VRRP priorities to the status of tracked objects such as interface or IP route states.
Object tracking is an independent process that manages creating,
Which statement about access lists that are applied to an interface is true?
You can configure one access list, per direction, per layer 3 protocol.
View the exhibit. An attempt to deny web access to a subnet blocks all traffic from the subnet. Which interface command immediately removes the effect of ACL 102?
no ip access-group 102 out
What is the alert message generated by SNMP agents called?
How many addresses will be available for dynamic NAT translation when a router is configured with the following commands? Router(config)#ip nat pool TAME 22.214.171.124 126.96.36.199 netmask 255.255.255.224 Router(config)#ip nat inside source list 9 pool TAME
What is the subnet address for the IP address 172.19.20.23/28?
