MCM Exchange Server 3 — Questions and Answers
Question 1: In Exchange 2010, what is the role of the witness server in a Database Availability Group with an even number of members?
- It stores a backup copy of all databases
- It provides an additional vote to achieve quorum (Correct answer)
- It acts as the primary Hub Transport server
- It hosts the arbitration mailbox
Correct answer: It provides an additional vote to achieve quorum
The witness server holds a file share witness that casts a tiebreaker vote, allowing the DAG to maintain quorum when the member count is even.
Question 2: A user reports that Outlook Anywhere connectivity fails after a certificate is renewed. Which Exchange component's certificate binding must be updated?
- Hub Transport SMTP listener
- Client Access server IIS binding (Correct answer)
- Edge Transport TLS certificate
- Mailbox server RPC encryption
Correct answer: Client Access server IIS binding
Outlook Anywhere (RPC over HTTP) terminates at the Client Access server's IIS; the new certificate must be bound to the Default Web Site and the RPC proxy virtual directory.
Question 3: Which Exchange 2010 transport feature ensures that a message is not permanently lost if a Hub Transport server goes offline before delivery?
- Redundant message store
- Shadow Redundancy (Correct answer)
- Safety Net
- Back Pressure
Correct answer: Shadow Redundancy
Shadow Redundancy keeps a shadow copy of each in-transit message on an alternate Hub Transport server until primary delivery is confirmed.
Question 4: An organization wants to archive inbound email for litigation purposes before it reaches end-user mailboxes. Which Exchange feature accomplishes this?
- Transport Rules with the 'Bcc' action
- Journal Rules targeting the Transport service (Correct answer)
- Managed Folder policies
- In-Place eDiscovery
Correct answer: Journal Rules targeting the Transport service
Journal Rules can be configured to send a journal report (with the original message) to a designated journaling mailbox before or during delivery.
Question 5: What Exchange 2010 feature throttles resource consumption per user to prevent a single client from degrading server performance?
- Back Pressure
- Client Throttling Policy (Correct answer)
- Connection Rate Limiting
- Store Driver Throttling
Correct answer: Client Throttling Policy
Client Throttling Policies define per-user resource budgets (connections, CPU time, RPC operations) and throttle clients that exceed those budgets.
Question 6: Which protocol does Outlook Web App (OWA) in Exchange 2010 use to communicate with the Mailbox server when the CAS and Mailbox roles are on separate servers?
- MAPI over TCP
- Exchange Web Services (EWS) (Correct answer)
- RPC over HTTP
- IMAP4
Correct answer: Exchange Web Services (EWS)
When CAS and Mailbox roles are separated, the CAS proxies OWA requests to the Mailbox server using Exchange Web Services (EWS) over HTTPS.
Question 7: An administrator configures a Receive Connector with the 'ExchangeUsers' permission group. What does this allow?
- Anonymous relay from the Internet
- Authenticated SMTP submission from internal Exchange servers (Correct answer)
- Edge Transport server SMTP relay
- Partner organization TLS connections
Correct answer: Authenticated SMTP submission from internal Exchange servers
The ExchangeUsers permission group grants authenticated Exchange users the right to submit messages via SMTP, typically used for internal client SMTP submission.
