MCTS 70-642 Microsoft 70-642 2 — Questions and Answers
Question 1: A company uses BranchCache in Hosted Cache mode. Which port must be open on the hosted cache server for clients to retrieve cached content?
- TCP 80
- TCP 443 (Correct answer)
- TCP 3702
- TCP 8443
Correct answer: TCP 443
BranchCache Hosted Cache mode uses TCP port 443 (HTTPS) for secure client-to-cache communication.
Question 2: You need to configure a DHCP scope so that a specific server always receives the same IP address. Which DHCP feature should you use?
- DHCP exclusion range
- DHCP reservation (Correct answer)
- DHCP superscope
- DHCP split scope
Correct answer: DHCP reservation
A DHCP reservation binds a specific IP address to a client's MAC address so the client always receives the same address.
Question 3: Which IPv6 address type is routable on the internet and globally unique?
- Link-local (FE80::/10)
- Unique local (FC00::/7)
- Site-local (FEC0::/10)
- Global unicast (2000::/3) (Correct answer)
Correct answer: Global unicast (2000::/3)
Global unicast addresses (2000::/3) are publicly routable on the IPv6 internet, equivalent to IPv4 public addresses.
Question 4: A technician wants to verify that DNS name resolution is working for a specific record type. Which command-line tool provides the most granular control over query type?
- ping
- nslookup (Correct answer)
- ipconfig /flushdns
- netstat
Correct answer: nslookup
Nslookup allows you to specify query types (A, MX, SRV, PTR, etc.) and target specific DNS servers for granular resolution testing.
Question 5: You configure Network Access Protection (NAP) with DHCP enforcement. Non-compliant clients should receive a restricted IP address. Where do you configure the restricted network scope?
- Network Policy Server (Correct answer)
- DHCP server scope options
- DHCP server class options
- Windows Firewall policy
Correct answer: Network Policy Server
The Network Policy Server (NPS) defines the restricted network and instructs the DHCP server to assign restricted-network IP addresses to non-compliant clients.
Question 6: Which routing protocol is a link-state protocol supported natively by the Windows Server 2008 RRAS service?
- RIP version 2 (Correct answer)
- OSPF
- EIGRP
- BGP
Correct answer: RIP version 2
Windows Server 2008 RRAS supports RIP version 2 as a built-in dynamic routing protocol; OSPF support was removed from Windows Server.
Question 7: An administrator creates a new stub zone for contoso.com on an internal DNS server. What records does the stub zone store?
- All resource records for contoso.com
- Only SOA, NS, and glue A records for contoso.com (Correct answer)
- Only A and AAAA records for contoso.com
- Only MX records for contoso.com
Correct answer: Only SOA, NS, and glue A records for contoso.com
A stub zone stores only the SOA, NS, and necessary glue A records needed to locate the authoritative name servers for the zone.
