Q

A Send connector can be configured to use DNS Mail Exchange (MX) resource records to route mail automatically. In this configuration, the DNS client on the source server must be able to resolve public DNS records. In this case, the Send connector uses the external DNS list that you specify by using the ExternalDNSServers parameter. For example, the following two commands specify an external DNS list and configure Send Connector01 to use this list: ______.

A

Set-TransportServer –Identity VAN-EX1 –ExternalDNSServers 192.168.30.2,10.10.50.10

As with Send connectors, you can configure the usage type of a Receive connector and determine the default security settings for that connector. You might also need to configure bindings by using the RemoteIPRanges parameter. For example, the following command creates the Receive connector Receive Connector01 with the Custom usage type. This connector listens for incoming SMTP connections on the IP address 10.10.10.1 and port 25 and accepts incoming SMTP connections only from the IP range 192.168.8.1 through 192.168.8.127: ______.

The following command specifies a maximum message size of 100 MB, a connection timeout of 20 minutes, and a connection inactivity timeout of 15 minutes for the ReceiveConnector01 Receive connector: ______.

A

Set-ReceiveConnector –Identity ReceiveConnector01 –MaxMessageSize 100MB -ConnectionTimeout 00:20:00 -ConnectionInactivityTimeout 00:15:00

41
Q

You should be aware that the server originating a message and the server receiving it exchange certificates from a ______ trusted CA.

A
42
Q

Exchange 2010 Setup creates a self-signed certificate and TLS is enabled by default. You can ______ this certificate to use it on additional servers. If necessary, you can replace it with certificates that are issued by a trusted third-party CA.

A

clone

43
Q

You can use the EMS ______ cmdlet to generate TLS keys. These keys consist of the TLS certificate and related private keys. You can specify certificate metadata that enables different services to use the same certificate and private key. This metadata is stored in fields in the resulting certificate. You can also generate a certificate request that you can send to a third party or other public key infrastructure CA.

A

New-ExchangeCertificate

44
Q

Running the ______ cmdlet without parameters generates a self-signed certificate with the FQDN of the server as the subject name.

A

New-ExchangeCertificate

45
Q

You can use this self-signed certificate for direct trust authentication and encryption between Edge Transport servers and Hub Transport servers. The certificate is published to Active Directory so that Exchange direct trust can validate the authenticity of the server for MTLS. You can also specify subject name and whether the private key is exportable. For example, the following EMS command creates a certificate with an exportable private key and a subject name defined by Country/Region = US, Organization = Adatum.com, and Common Name = mail.adatum.com: ______.

A

New-ExchangeCertificate –SubjectName “c=US, o=adatum.com, cn=mail.adatum.com” –PrivateKeyExportable $true

46
Q

You can use the ______ cmdlet to generate a certificate request that you can send to a CA. You can output the request to the command-line console; send the certificate request to a local, external, or commercial CA; or save the certificate request to a text file. The following EMS command generates a certificate request with a subject name c=UK, o=Blue Sky Airlines, cn=mail.blueskyairlines.co.uk, a subject alternate name blueskyairlines.co.uk, and an exportable private key: ______.

A

New-ExchangeCertificate,

New-ExchangeCertificate -GenerateRequest -SubjectName “c=UK,o=Blue Sky Airlines,cn=mail.blueskyairlines.co.uk” -DomainName blueskyairlines.co.uk -PrivateKeyExportable $true

47
Q

As an Exchange professional, you know that anonymous relay on Internet SMTP can be a serious security deficiency. You should therefore be aware that In Exchange 2010, relaying is typically handled by using ______ domains.

A

accepted

48
Q

An ______ relay domain is a domain for which the Exchange organization accepts email messages from external locations but does not process them locally, and forwards them to an external mail server.

A

external

49
Q

An ______ relay domain is a domain for which the Exchange organization accepts email messages from external locations but forwards them to another internal mail system.

A

internal

50
Q

You should be aware that MTLS authenticates the ______ for the recipient and the recipient for the server, and that some implementations of TLS (for example, SSL) do not.

A

sender

51
Q

Exchange 2010 attempts to use TLS for all remote connections, and all traffic between Edge Transport servers and Hub Transport servers is authenticated and encrypted by using ______.

A

MTLS

52
Q

You can require TLS authentication on Send and Receive connectors. For example, the following EMS command creates a Receive connector for incoming messages on port 25 from the IP address range 10.10.0.1 through 10.10.0.24 and specifies that all messages coming from this range must use TLS: ______.

A

New-ReceiveConnector –Name Secure –Bindings 0.0.0.0:25 –RemoteIPRanges 10.10.0.1-10.10.0.24 –RequireTLS $true

53
Q

You should be aware that the maximum size of messages specified for an IP site link sent through a Send connector is not always the same as the maximum message size configured on a Send connector. By no means do all the messages that are sent through a Send connector pass over an IP site link. Remember that if a message is subject to both Send connector and sitelink restrictions, the ______ of the two maximum message sizes applies.

A

smaller

54
Q

You use the ______ cmdlet to view configuration information about an Active Directory IP site link. You use the ______ cmdlet to configure maximum message size.

A

Get-AdSiteLink,

Set-AdSiteLink

55
Q

By default, Exchange 2010 does not limit the size of messages that are relayed between Hub Transport servers in different Active Directory sites, but it might become necessary to specify size limits because of traffic considerations. For example, the following command sets the maximum message size on the Active Directory IP site link LINKAB to 1 GB: ______.

A

Set-AdSiteLink -Identity LINKAB -MaxMessageSize 1GB

56
Q

The default value for the maximum size of a message sent by a Send connector is ______ MB.

A

10

57
Q

You can use the MaxMessageSize parameter with the EMS ______ or New-SendConnector cmdlet if you need to specify a maximum message size other than the default value. You can also configure the maximum message size on a Receive connector. The following command specifies a maximum message size of 100 MB for the Receive connector ReceiveConnector01: ______.

A

Set-SendConnector,

Set-ReceiveConnector –Identity ReceiveConnector01 –MaxMessageSize 100MB

58
Q

A Foreign connector has an ______ maximum message size by default. Answer: True. The following EMS command configures the maximum message size on ForeignConnector01 to be 50 MB: ______.
