- What is the goal of change control In network maintenance and troubleshooting?
- to decrease the cost of equipment
- to reduce the mean time between failures
- to simplify the documentation process
- to increase network uptime *
- to automate the task of network documentation
- Which two components are normally considered part of change control? (Choose two.)
- the cost of network changes
- the authorization that is required to make changes *
- the technology that is used to implement changes
- the staff changes that are required to carry out repairs
- the time when changes can be made *
- What are two facts regarding the information that is collected for baseline creation? (Choose two.)
- The information is the same for all networks.
- It should be collected only once and then archived for future reference.
- It can be used for capacity planning.*
- It can be collected using tools such as NBAR, NetFlow, and SNMP.*
- It should be limited to only a few key performance statistics.
- What type of information can be gathered by using SNMP during the process of collecting baseline information?
- basic performance statistics about the Interface load for critical network links*
- basic performance statistics to profile different types of traffic on the network
- basic performance statistics via the use of show commands
- basic performance statistics for Layer 2 and Layer 3 protocols
- Which three IOS features can be used to keep the network documentation accurate? (Choose three.)
- basic performance statistics
- policy compliance
- Embedded Event Manager *
- rollback feature *
- performance monitoring
- configuration archive *
- Which Cisco IOS baseline performance tool can be used to measure delay and jitter across the network infrastructure?
- IP Service Level Agreement (IP SLA) *
- NetFlow
- Network Based Application Recognition (NBAR)
- Simple Network Management Protocol (SNMP)
- A network administrator executes the show processes cpu command on a production router and notices that the average CPU load over the past 5 seconds was 97% and over the last one minute was around 39%. What should the administrator do next?
- Compare the result to the baseline for an accurate assessment.*
- Replace the router as soon as possible because it has reached capacity.
- Nothing. This is normal behavior for an ISR router.
- Contact the service provider because the contract is not being fulfilled as specified in the SLA.
- Which two procedures can be implemented to ensure that current backups of all device configurations are maintained? (Choose two.)
- Implement a system to create automatic configuration backups.*
- Create configuration backups as soon as an issue is reported with network performance.
- Update configuration backups only after major network outages.
- Password protect all devices to prevent configuration changes,
- Log all configuration change events to a syslog server.*
- Which IOS feature can be leveraged to maintain current backups of all device configurations?
- Cisco Configuration Manager
- Cisco Prime Infrastructure
- Cisco Feature Navigator
- Cisco Embedded Event Manager *
- Which three types of data are useful for creating a baseline? (Choose three.)
- basic performance statistics like the interface load for critical network links and the CPU load and memory usage of routers and switches*
- Remote Monitoring (RMON), Network Based Application Recognition (NBAR), and NetFlow statistics*
- DHCP and NAT translation statistics
- network performance characteristics*
- number of infrastructure routers and switches
- switch interface statistics of all access ports
- What is a purpose of a disaster recovery plan?
- to minimize downtime in the event of a failed device *
- to evaluate current devices and software images and determine if they need to be upgraded
- to ensure all devices are continuously monitored at all times
- to prevent a single point of failure
- Refer to the exhibit. A network administrator is troubleshooting a routing related problem. Which two facts can be concluded based on the generated output of the show logging command? (Choose two.)
- Router R1 has established a stable IBGP peering relationship with the neighbor at IP address 192.168.2.2.
- The BGP-5-ADJCHANGE message indicates an error with the subnet mask for the specified prefix.
- Interface Serial 0/1 has been incorrectly configured with IP address 192.168.2.2.
- Router R1 has established a stable EBGP peering relationship with the neighbor at IP address 192.168.2.2.
- Interface Serial 0/1 is flapping.*
- Router R1 is unable to establish a stable BGP peering relationship with the neighbor at IP address 192.168.2.2.*
- What are two situations where escalation of a case is recommended? (Choose two.)
- when insufficient knowledge and skills exist *
- when the end-user reporting the problem is a manager
- when there is a lack of desire to solve the issue
- when shift work requires handing off the problem *
- when the cause of the problem is within the area of responsibility of the troubleshooter
- when there is an inability to clearly communicate the problem
