QUESTION 1:

You are the new network administrator for Certkiller . The network includes an ISA Server computer named Certkiller 1. Certkiller 1 was configured by a previous administrator. Certkiller 1 functions as a firewall between the Certkiller network and the Internet.
During a routine audit of Certkiller 1’s log files, you discover that several non-standard services are installed and configured to start automatically. Your manager tells you that the previous administrator installed additional services on Certkiller 1 for monitoring and reporting purposes. Your manager wants Certkiller 1 to function only as a firewall.
You want to ensure that no additional services on Certkiller 1 are opening ports on Certkiller 1. You do not want to change the status of any built-in services.
What should you do?

A. Run the nbtstat – an command.
Disable any of the additional services that are listed as Registered. B. Run the netstat -an command.
Disable all services that are listening on authorized ports.
C. Run the ISA Server Security Wizard to set the system security level of Certkiller 1 to Secure.
D. Run the ISA Server Security Wizard to set the system security level of Certkiller 1 to Limited Services.

Answer: D
System hardening has three steps:
Dedicated (only Firewall, would be the best, but is not here as a point), Secure (ISA as Firewall and Caching Maschine),
Limited Services (lowest step, ISA and other services).
nbtstat has no “-an” and “netstat -an hostname” shows no ports and no
Protocols, it shows netbios nametable and macaddress
. According to the MOC, ISA Server security has three levels: Dedicated, Limited Services (Use this settings to function as a combined firewall and cache server), and Secure (use this settings when the ISA Server performs other functions, such as running web server, database, etc.)
Security level For a server For a domain controler
Dedicated hisecws.inf hisecdc.inf
Limited Services Securews.inf securedc.inf
Secure Basicsv.inf basicdc.inf

QUESTION 2:

You are the network administrator for Certkiller . The network includes 1,000 Microsoft Windows 98
client computers, 5,000 Windows XP Professional client computers, and 15 UNIX-based client computers. All client computers use Microsoft Internet Explorer as their only Web browser.
You purchase a new ISA Server computer named Certkiller 1. You configure Certkiller 1 to function as a firewall and cache server and you install it so that it connects to Certkiller ’s network to the Internet. The relevant portion of the network configuration is shown in the exhibit.

Certkiller policy states that only users who are authenticated by the domain are allowed to send any traffic to the Internet. However, this policy contains an exception that allows unauthenticated users to
send HTTP traffic after they provide the name and password of a special user account.
You configure Certkiller 1 to require authentication for all outgoing traffic and to support Basic and
Integrated authentication. Another administrator creates the special user account. You need to comply with Certkiller policy.
Which two actions should you take (Each correct answer presents part of the solution. Choose two)

A. Configure Certkiller 1 so that the system security level is set to Secure.
B. Install the Firewall Client software on all Windows-based client computers.
C. Configure Internet Explorer on all client computers to use Certkiller 1 as the proxy server.
D. Configure all client computers to use Certkiller 1’s internal IP address as their default gateway.
E. Modify the local address table on Certkiller 1 so that all internal IP addresses are included.

Answer: A, C Explanation:
A and C, ISA Firewall and Caching is supported by all OS. B is not going, because there are UNIX-Clients.
E is not going, because this is only working with Firewallclients
D is not good, because SecureNATClients could not work with Authorisation.

QUESTION 3:

You are the enterprise administrator for Trey Research. Certkiller network includes one Microsoft Windows 2000 domain and four sites. Each site has 500 client computers. The relevant portion of your network configuration is shown in the exhibit.

The Amsterdam site contains an array of three ISA Server computers. This array provides Internet access to client computers in all four sites.
Trey Research wants to reduce the bandwidth used on internal connections for Internet access. Amsterdam will remain the only site with a direct connection to the Internet.
Which two actions should you take? Each correct answer presents part of the solution. (Choose two)

A. Install additional ISA Server computer in Berlin, Rome, and Paris. Join these servers to Corp ISA Array.
B. Install additional ISA Server computer in Berlin, Rome, and Paris. Create a separate array in each of these sites.
C. Create a routing rule in Berlin, Rome, and Paris to route client requests to Corp ISA array.
D. Install the firewall client software on the ISA server computers in Berlin, Rome, and Paris. Specify
Corp ISA array as the destination.
E. Create a web publishing rule in Berlin, Rome, and Paris. Redirect all client requests to Corp ISA Array.
F. Configure the ISA server computers in Berlin, Rome, and Paris to use one of the IP addresses of
Corp ISA Array for intra-array communication. Answer: B, C
Explanation:
B: We create a separate ISA server array at each site to reduce unnecessary network traffic between sites.
C: Requests at the new ISA servers should be routed to the ISA array in Amsterdam. Incorrect Answers
A: ISA servers in different sites should not be members of the same array. Performance would decrease due the increase in intersite communication.
D: Firewall client software could be useful on client, not on ISA servers however.
E: Web publishing rules are used to make a web server accessible to external users. A web publishing rule is of
no use here.
F: ISA servers in different sites should not be members of the same array. Performance would decrease due the increase in intersite communication.
