Route summarization
Ingore the networks between routers, what is the summarized route pointing back from HQ to A, B and C ?
What is the static route required in HQ router ?
Thx

Without knowing what networks are at HQ, it's impossible to say. But since HQ is also connected to the internet, typically a default route would be advertised to the remotes.
Best would be setup a routing protocol such as OSPF between the HQ router and A, B and C. If you want static routes then you will need 3 of them as follows:
ip route 172.16.10.0 255.255.255.0 next-hop address or exit interface
ip route 172.16.20.0 255.255.255.0 next-hop address or exit interface
ip route 172.16.30.0 255.255.255.0 next-hop address or exit interface
ip route 172.16.10.0 255.255.255.0 next-hop address or exit interface
ip route 172.16.20.0 255.255.255.0 next-hop address or exit interface
ip route 172.16.30.0 255.255.255.0 next-hop address or exit interface

In case I use RIP, can I configure the summarized route as 172.16.10.0 /19 ?

No you can't summarize here because your router has to distinguish between the exit interfaces for each network.

Thx. But the question is asking " what is the summarized route pointing back from HQ to A, B and C"
I just wonder why it is asking the network command under the RIP or OSPF ....

So, static route will be the solution and we can use summarization in this case, correct ?
Thx again.

Yes you will need to setup 3 static routes on the HQ router as I stated earlier. You cannot do any summarization in your setup. Better option would be to use OSPF routing protocol between HQ and A,B and C.
The following static routes should go on the HQ router:
ip route 172.16.10.0 255.255.255.0 next-hop address or exit interface
ip route 172.16.20.0 255.255.255.0 next-hop address or exit interface
ip route 172.16.30.0 255.255.255.0 next-hop address or exit interface
The following static routes should go on the HQ router:
ip route 172.16.10.0 255.255.255.0 next-hop address or exit interface
ip route 172.16.20.0 255.255.255.0 next-hop address or exit interface
ip route 172.16.30.0 255.255.255.0 next-hop address or exit interface
