MCTS 70-642 Technology & Digital Applications 5 — Questions and Answers
Question 1: A Windows Server 2008 R2 administrator needs to monitor network bandwidth usage by application on the server. Which built-in tool provides per-process network I/O data?
- Network Monitor 3.4
- Resource Monitor (Correct answer)
- Performance Monitor with Network counters
- Netstat -b
Correct answer: Resource Monitor
Resource Monitor (resmon.exe) shows real-time per-process network activity including bytes sent/received on the Network tab.
Question 2: Which IPv6 address type is equivalent to IPv4's 169.254.x.x APIPA range and is automatically assigned when no router or DHCPv6 server is present?
- Global unicast address (2000::/3)
- Link-local address (FE80::/10) (Correct answer)
- Unique local address (FC00::/7)
- Site-local address (FEC0::/10)
Correct answer: Link-local address (FE80::/10)
Link-local addresses (FE80::/10) are automatically configured on every IPv6 interface and are only valid on the local network segment.
Question 3: An organization wants to use BranchCache in Windows Server 2008 R2 to reduce WAN traffic. What are the two modes available?
- Distributed Cache mode and Hosted Cache mode (Correct answer)
- Active mode and Passive mode
- Client mode and Server mode
- Pull mode and Push mode
Correct answer: Distributed Cache mode and Hosted Cache mode
BranchCache operates in Distributed Cache mode (peers cache data locally) or Hosted Cache mode (a branch server caches data centrally).
Question 4: A Windows Server 2008 R2 server running RRAS is configured for demand-dial routing. The connection drops frequently. Which setting should the administrator adjust to keep the connection active?
- Increase the idle disconnect timeout or set it to never disconnect (Correct answer)
- Increase the MTU size on the WAN interface
- Enable dead gateway detection in TCP/IP settings
- Configure OSPF routing instead of static routes
Correct answer: Increase the idle disconnect timeout or set it to never disconnect
Demand-dial interfaces disconnect after a period of idle time; setting the idle timeout to 0 (never) or a larger value prevents unwanted disconnections.
Question 5: Which Windows Server 2008 R2 command-line tool allows an administrator to display and modify the IP routing table?
- netstat -r
- route print / route add (Correct answer)
- ipconfig /all
- arp -a
Correct answer: route print / route add
The 'route' command with 'print' displays the routing table and with 'add' allows administrators to add persistent or non-persistent static routes.
Question 6: A company implements NAP with DHCP enforcement on Windows Server 2008 R2. Non-compliant clients receive an IP address but can only reach remediation servers. How is this achieved?
- Non-compliant clients are placed in a separate VLAN automatically
- NPS instructs the DHCP server to assign limited routes and a restricted IP to non-compliant clients (Correct answer)
- Windows Firewall blocks all traffic except to remediation servers on non-compliant clients
- Non-compliant clients receive a public IP with no default gateway
Correct answer: NPS instructs the DHCP server to assign limited routes and a restricted IP to non-compliant clients
With DHCP enforcement, NPS signals the DHCP server to assign non-compliant clients a restricted address with routes only to remediation servers.
Question 7: An administrator must ensure that DNS records for servers in a Windows Server 2008 R2 domain are updated automatically when a server's IP address changes. Which feature must be enabled?
- DNS Dynamic Update (DDNS) on the DNS zone and DHCP registration on the server (Correct answer)
- Manual SOA record update via DNS Manager
- Zone transfer to all secondary servers
- Active Directory Sites and Services replication
Correct answer: DNS Dynamic Update (DDNS) on the DNS zone and DHCP registration on the server
Dynamic DNS allows DHCP clients and servers to automatically update A and PTR records in DNS when IP addresses change.
