This change will not require a restart in the application when using AppInternals Xpert:

A. Changes in jida.config

B. Enabling monitoring of generic classes with config.package metrics

C. Changes in the -agentpath parameter

D. Enabling cross-tier transactions

If a proxy or load balancer changes or hides internet protocols (IPs), how could AppResponse Xpert (ARX) determine the originating IP? (Select 2)

A. This is not currently supported.

B. Monitor web traffic in a location where AppResponse Xpert can observe the originating and server IPs directly.

C. Configure all intervening devices to include X-Forwarded-For (XFF) headers.

D. AppResponse Xpert is able to expose the originating and server IPs even when intervening devices hide them.

In the Database Performance module, the Response Time (First Response) (sec) metric refers to:

A. The cold cache response time, when the information is first requested from the database

B. The response time from the warm cache, known as the First Response table

C. The response time measured from the start of the database query to the receipt of the final response packet

D. The response time measured from the start of the database query to the receipt of the first response packet

E. The response time for stored procedure queries into the database

Which of the following is not correct regarding packet deduplication in AppResponse Xpert (ARX)?

A. ARX compares 40 bytes of the IP header (minus the ToS, TTL, and Checksum fields) and TCP header for each packet. It calls it a duplicate if those headers are identical across two packets received inside of the deduplication packet buffer or time window.

B. ARX associates the TCP segment seen first with the corresponding VLAN ID. AppResponse Xpert then ignores all other identical TCP segments that arrive (in its deduplication time window or buffer) encapsulated in other VLANs.

C. If two identical TCP segments arrive encapsulated in identical VLAN IDs, then only the last one is kept and used for analysis; the first are discarded.

D. If two identical TCP segments arrive and only one of them is encapsulated in the 802.1q VLAN header, then VLAN-based deduplication will associate a fake VLAN ID of -1 with the non-802.1q segment and the TCP segment that is seen first in the current deduplication window is considered the original packet. Identical TCP segments with other VLAN IDs are ignored.

Which metrics does AppResponse Xpert compute for monitoring? (Select 3)

A. TCP out-of-sequence

B. TCP retransmission

C. TCP frozen window

D. TCP reset

E. TCP connection failed
