What can cause a memory leak on a router?

How can an administrator determine if a memory leak is present in a router?

A network administrator has configured a Cisco IOS device to provide server load balancing (SLB) for the corporate web server. What is required on the client side to ensure proper load balancing?

Which three hardware components are common in the architectures of all Catalyst switch families?(Choose three.)

A network administrator wishes to use debug commands to observe how a router processes each individual packet on an interface. Which packet switching solution should be implemented on the interface to accomplish this task?

A network is experiencing performance degradation on an access switch where user traffic is subject to granular QoS policy and security inspection. Which switch component or components should be inspected by the network administrator to help determine the issue?

Refer to the exhibit. Based on the output of the show interfaces command, which two statements are true?(Choose two.)

Refer to the exhibit. A network administrator enables AutoQoS on a PPP link that is currently active. Once AutoQoS is enabled the link goes down. What should the administrator do to correct this problem?

Refer to the exhibit. Users on the network are complaining that transferring large files to the SRV1 server takes hours. A network administrator runs a few tests on both switches to investigate the problem. On the basis of the provided outputs, what could be the possible reason for problem?

Refer to the exhibit. A network administrator is investigating performance issues of the access switch. On the basis of the provided outputs, what conclusion can be made about the switch performance?

What reported error counter describes frames that do not end with an integral number of octets and have a bad cyclic redundancy check (CRC)?

Refer to the exhibit. A network administrator has noticed that the IP SLA probe did not run as expected.What should the administrator do to correct this problem?

What must a system administrator do to allow NBAR to recognize a new protocol without having to upgrade the Cisco IOS image?

Refer to the exhibit. What can be determined about the operation of interface FastEthernet 0/2?

Refer to the exhibit. A network administrator is troubleshooting the switching path on a router. Based on the exhibited output, what can be concluded?

A network administrator plans to implement QoS in the network by using the Cisco AutoQoS tool. What should be done in the first phase of the automation process?

Which three Cisco packet switching methods must a network administrator be familiar with in order to troubleshoot a router performance issue that is related to the switching path? (Choose three.)

Refer to the exhibit. What can be determined from the exhibited output?

A network administrator keeps receiving "%SYS−2−MALLOCFAIL" console messages. Further investigation reveals that the buffer pool continues to grow. The CCO knowledge base identified the cause of the problem as a result of a buffer memory leak due to an IOS software bug. What should the administrator do to rectify this problem?

What are three indicators of a cabling issue on a switch? (Choose three.)
