  1. General

  2. Browser

  3. Network

  4. Internet Protocol

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In LoadRunner's Runtime Settings, the 'General' node contains settings that apply universally across all protocols - think, pacing, logging, and other fundamental settings. Protocol-specific nodes like Browser (for Web), Network (for network-level protocols), and Internet Protocol (for specific IP settings) are only available when those particular protocols are selected in the script.

  3. IMAP

  4. MAPI

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

UCF (Universal Content Transfer) in Documentum uses HTTP as its transport protocol for content transfer between client and server. It's not FTP, IMAP, or MAPI - these are entirely different protocols for different purposes.

  1. 8080

  2. 7334

  3. 443

  4. 7338

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The default UCF port number in Documentum is 7338. Port 8080 is commonly used for web servers, 7334 might be mistaken for the UCF port, and 443 is the standard HTTPS port. The correct UCF default is 7338.

  1. Configures the network parameters and enables all the http request to reach vpn server.

  2. Configures the network parameters and enables all the http request with appropriate dns suffix to reach vpn server.

  3. Configures the network parameters and enables all the http request with appropriate dns suffix to reach nielsen server.

  4. Configures the network parameters and enables all the http request with appropriate dns suffix to reach nielsen ntework.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Checkpoint VPN configures network parameters and routes HTTP requests with appropriate DNS suffixes to reach the VPN server. The key aspect is the DNS suffix handling - requests with matching suffixes are routed through the VPN tunnel. Option A is incomplete (missing DNS suffix). Options C and D incorrectly mention 'nielsen' instead of 'vpn' server.

Multiple choice technology web technology
  1. Request reaches the TCS dns servers and get resolved.

  2. Request reaches the TCS domain server and get resolved.

  3. Request reaches the vpn domain server and get resolved.

  4. Request reaches the vpn dns servers and get resolved.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

When VPN is connected inside TCS, DNS requests are routed through the VPN's DNS servers, not TCS infrastructure. The request to hermes.nielsen.com reaches the VPN DNS servers and gets resolved through the VPN tunnel. Option A incorrectly says TCS DNS servers. Options B and C mention 'domain server' instead of 'DNS server'.

Multiple choice technology web technology
  1. Request reaches the TCS dns servers and get resolved.

  2. Request reaches the vpn dns servers and get resolved.

  3. Request reaches the TCS domain server and get resolved.

  4. Request reaches the vpn domain server and get resolved.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When VPN is disconnected inside TCS, DNS requests use the default corporate DNS infrastructure - in this case, TCS DNS servers. The request to hermes.nielsen.com reaches TCS DNS servers and gets resolved (or fails if the domain is only accessible via VPN). Option B is incorrect because VPN is disconnected.

Multiple choice technology web technology
  1. 3

  2. 2

  3. 1

  4. 4

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The VPN infrastructure in this context has 2 DNS servers. This is a standard configuration for redundancy and load balancing. Having exactly 2 DNS servers provides failover capability without unnecessary complexity.

Multiple choice technology web technology
  1. POP3

  2. IMAP

  3. SMTP

  4. MIME

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

IMAP (Internet Message Access Protocol) is the correct protocol for receiving emails. It allows email clients to access and manage email messages stored on a mail server. POP3 (A) is also for receiving but is an older protocol with limitations. SMTP (C) is for SENDING emails, not receiving. MIME (D) is a format specification, not a protocol.

Multiple choice technology web technology
  1. enterprisenet.org

  2. nielsen.com

  3. narheapp.org

  4. answersint.nielsen.com

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To solve this question, the user needs to have knowledge about DNS suffix and Checkpoint VPN. The user needs to identify which DNS suffix is the default for Checkpoint VPN.

The correct answer is option A: enterprisenet.org. This is the default Checkpoint VPN DNS suffix. Checkpoint VPN is a software-based VPN client and firewall solution which uses DNS suffix to resolve domain names to IP addresses. The DNS suffix is added to the hostname when making a DNS query. In the case of Checkpoint VPN, the default DNS suffix is enterprisenet.org. Options B, C, and D are incorrect, as they are not related to Checkpoint VPN or its default DNS suffix.

Multiple choice technology web technology
  1. Since it is private address, more secure to use.

  2. Since it is private address, cost effective.

  3. Since it is public address, more secure to use.

  4. Since it is public address, cost effective.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

IP addresses starting with 10 are private IP addresses (10.0.0.0/8 range). Using private addresses is cost-effective because organizations don't need to purchase public IP addresses for internal infrastructure. Option A incorrectly claims private addresses are 'more secure' - security depends on other factors. Options C and D are wrong because 10.x is private, not public.

Multiple choice technology performance
  1. nmon

  2. netmon

  3. netstat

  4. nstat

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The netstat (network statistics) command is a standard command-line utility used to monitor network status, active connections, routing tables, and interface statistics. Distractors like nmon, netmon, and nstat are either different system monitoring utilities or not standard commands for basic network status display.

A,B,C Correct answer
Explanation

Quova, IP2Location, and MaxMind are all IP geolocation and intelligence services that can integrate with Oracle Adaptive Access Manager's open APIs to provide location-based risk assessment and fraud detection capabilities.

Multiple choice technology testing
  1. Number which indicates the server

  2. GUID number used in URL

  3. Unique number used to create site

  4. Number helps in identifying the site name.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In web server administration (like IIS hosting), a port number acts as a unique identifier used to host and bind a specific website on the server. Along with the IP address and host header, the port distinguishes sites sharing the same hardware.

Multiple choice technology web technology
  1. SOAP

  2. Http

  3. RMI-IIOP

  4. RPC

Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation

Web services are called over both SOAP (which itself rides on HTTP) and directly over HTTP (especially RESTful services). SOAP is a protocol that uses HTTP as transport, and HTTP is the underlying network protocol. RMI-IIOP is specific to Java CORBA, not standard web services. RPC is a general concept but not specific protocol in this context.
